Question 1

Is CCC RBQ licensed?

Accepted Answer

Yes. Castelli & Carson Construction holds two active RBQ (Régie du bâtiment du Québec) licenses — the mandatory provincial licenses for contractors in Quebec. RBQ 1.2 covers residential roofing and RBQ 1.3 covers general commercial construction. Both licenses are active and publicly verifiable through the RBQ contractor directory. We encourage every client to verify our credentials before signing any contract. Visit the RBQ public search at rbq.gouv.qc.ca.

Question 2

What areas does CCC serve?

Accepted Answer

We serve the greater Montreal area and surrounding regions. Our dedicated service area pages cover Downtown Montreal, West Island, NDG (Notre-Dame-de-Grâce), Laval, the South Shore (Longueuil, Brossard, Boucherville), Westmount, Vaudreuil-Dorion, Île-Perrot, Plateau Mont-Royal, and Verdun & LaSalle. Each area page includes neighbourhood-specific information, local project examples, and a direct contact form. Visit our service areas at /areas/downtown-montreal, /areas/west-island, /areas/ndg, /areas/laval, /areas/south-shore, /areas/westmount, /areas/vaudreuil-dorion, /areas/ile-perrot, /areas/plateau-mont-royal, and /areas/verdun-lasalle.

Question 3

Are you fully insured?

Accepted Answer

Yes. CCC carries comprehensive general liability insurance and is fully CNESST compliant for worker safety on every job site. You can request our certificates of insurance at any time — we provide them as standard practice for all projects over $5,000. Our insurance coverage protects your property, our workers, and any third parties throughout the duration of any project. Uninsured contractors expose homeowners to significant liability — always ask for proof of insurance before any work begins.

Question 4

Do you offer free estimates?

Accepted Answer

Yes. We provide detailed, transparent written estimates at no charge. For most projects, we respond to estimate requests within 2 business hours and deliver the written estimate within 24 hours of our site visit. Estimates are broken down line-by-line by trade and phase so you know exactly what you are paying for. We never provide vague lump-sum quotes. Submit your request through our contact page or call (438) 808-1103.

Question 5

How long does a typical project take?

Accepted Answer

Project timelines vary significantly by type and scope. Residential shingle roof replacements typically take 1–3 days. Flat membrane roofing projects take 1–5 days. Kitchen renovations typically run 4–8 weeks. Bathroom renovations run 3–6 weeks. Basement finishing projects take 6–12 weeks depending on scope. Commercial construction timelines are project-specific. We provide a detailed phase-by-phase schedule in every written proposal so you know exactly what to expect week by week.

Question 6

Do you handle permits?

Accepted Answer

Yes. We research and manage the full permit application process for every project that requires one. In Montreal, permits are required for structural changes, electrical panel upgrades, new plumbing rough-ins, additions, and changes to egress. We file applications, coordinate inspections, and ensure your project is fully code-compliant and documented. Skipping permits creates serious liability at resale and can void home insurance — we never recommend cutting that corner.

Question 7

What makes CCC different from other contractors?

Accepted Answer

Several things set us apart: (1) Full RBQ licensing — verifiable online, covering both residential and commercial scopes. (2) Line-item transparency — every estimate is broken down by trade and phase, not a vague lump sum. (3) Digital project management — structured scheduling, milestone updates, and direct contractor communication throughout. (4) Written workmanship warranty — eligible projects are backed by documented warranty protection. (5) CCQ compliance — all trades are properly licensed and regulated. We built this company on the principles we wish every contractor operated by.

Question 8

Are you CCQ compliant?

Accepted Answer

Yes. CCQ (Commission de la construction du Québec) regulates all construction trades in Quebec. CCQ compliance means every tradesperson on your project is properly licensed, trained, and legally permitted to work in their trade in Quebec. Non-compliant work can void your home insurance, create issues at resale, and expose you to personal liability. All CCC subcontractors and employed trades are CCQ-compliant. We never use grey-market labour or unlicensed electricians or plumbers.

Question 9

Do you offer a workmanship warranty?

Accepted Answer

Yes. Eligible projects are backed by a written workmanship warranty — documented protection covering defects in our installation work for the applicable warranty period. Material warranties are separate and vary by manufacturer: IKO shingles carry 10–15 year manufacturer warranties, SOPREMA and IKO membrane systems carry product warranties of 10–25 years depending on the product. We walk you through all applicable warranties at the time of your estimate and deliver all warranty documentation at project close.

Question 10

How long does a flat roof last in Montreal?

Accepted Answer

A professionally installed 2-ply elastomeric membrane flat roof can reliably perform for 25–30 years in Montreal's climate when properly maintained. Lower-quality single-ply or poorly installed systems may fail in 10–15 years. Key longevity factors include proper drainage slope, quality of flashing at parapets and penetrations, correct heat-welded seam adhesion, and periodic inspection every 3–5 years. Visit our flat roof service page at /services/roofing/flat-roof-membrane for full details on our installation process.

Question 11

What is the best flat roof membrane for Quebec winters?

Accepted Answer

For most Montreal residential and light commercial applications, the gold standard is a 2-ply SBS-modified bitumen elastomeric membrane — typically SOPREMA Sopralene Flam or an equivalent IKO SBS system. SBS (Styrene-Butadiene-Styrene) modification gives the membrane exceptional cold-temperature flexibility, preventing cracking in Quebec's extreme winter conditions. The heat-welded torch-applied installation method creates seamless, fully bonded joints that resist water infiltration. TPO is an excellent energy-efficient alternative for commercial flat roofs.

Question 12

How much does flat roof replacement cost in Montreal?

Accepted Answer

Flat roof replacement costs in Montreal typically range from $8–$18 per square foot for a complete 2-ply elastomeric membrane system, depending on roof complexity, accessibility, existing membrane condition, and required deck repairs. A standard 1,000 sq ft flat roof replacement often falls between $9,000–$16,000 including materials, labour, and disposal. Additional costs apply for parapet wall waterproofing, drain replacement, and structural deck repair. We provide detailed line-item estimates — contact us at (438) 808-1103 for a free evaluation.

Question 13

Can a flat roof be repaired or does it need full replacement?

Accepted Answer

It depends on the condition and age of the existing membrane. Isolated punctures, small seam separations, and localized blistering can often be repaired if the membrane is less than 15–20 years old and otherwise in good condition. Signs that indicate full replacement is necessary: membrane nearing 25+ years old, widespread blistering or bubbling, multiple active leak points, saturated insulation beneath the membrane, or visible granule loss across large areas. We perform honest assessments — we will never recommend replacement when repair is the appropriate solution. See /services/roofing/flat-roof-membrane.

Question 14

What is elastomeric membrane roofing?

Accepted Answer

Elastomeric membrane roofing is the Quebec standard for flat and low-slope roofs. The membrane is composed of SBS-modified bitumen — asphalt reinforced with styrene-butadiene-styrene polymer — that provides exceptional elasticity, superior waterproofing, and resistance to cracking across a wide temperature range. A professional installation uses two integrated layers: a base sheet bonded to the deck for structural adhesion, and a granule-surfaced cap sheet heat-welded on top as the primary weather barrier. This system is engineered for Montreal's freeze-thaw cycle and can last 25–30 years when properly installed.

Question 15

What is EPDM roofing?

Accepted Answer

EPDM (ethylene propylene diene monomer) is a single-ply synthetic rubber membrane commonly used on commercial flat roofs. Its key advantages are excellent low-temperature flexibility, UV and ozone resistance, and a 50+ year track record of performance. Firestone RubberGard EPDM is one of the most recognized products in this category. EPDM is typically mechanically fastened or fully adhered rather than torch-applied, making it a practical choice for large commercial rooftop areas. We install EPDM systems on qualifying commercial projects.

Question 16

What is TPO roofing?

Accepted Answer

TPO (thermoplastic polyolefin) is a single-ply flat roof membrane known for its energy efficiency and commercial-grade performance. The white or light-coloured surface has high solar reflectivity, reducing rooftop heat absorption and lowering cooling costs. Seams are heat-welded for a watertight bond. Products like IKO PrevailPro TPO and Carlisle Sure-Weld TPO are commonly specified for Montreal commercial buildings. TPO is Energy Star compliant and available with up to 20-year NDL (No Dollar Limit) warranties on qualifying commercial installations.

Question 17

How do I know if my flat roof needs replacement?

Accepted Answer

Key warning signs: (1) Recurring interior water stains or active leaks after rain. (2) Visible membrane cracking, blistering, or extensive granule loss. (3) Standing water that persists more than 48 hours after rainfall (indicating drainage issues). (4) Soft or spongy areas when walking the roof (indicating saturated insulation beneath). (5) Membrane age of 20+ years. (6) Multiple past repairs that have not held. A professional inspection is the definitive answer — we offer free roof evaluations across Greater Montreal. Call (438) 808-1103 or visit /services/roofing/flat-roof-membrane.

Question 18

Do you repair flat roofs on triplexes and duplexes?

Accepted Answer

Yes — Montreal triplexes and duplexes are one of our core specialties. The iconic flat-roofed Montreal plex typically uses a 2-ply elastomeric membrane system, and these roofs require re-roofing every 20–30 years. We handle both full replacements and localized repairs on plex-style buildings, including proper parapet wall waterproofing, drain servicing, and building-permit coordination where required. We work regularly in NDG, Plateau Mont-Royal, Rosemont, and Verdun — the heart of Montreal plex territory. Visit /areas/plateau-mont-royal or /areas/ndg for local information.

Question 19

How long do asphalt shingles last in Montreal?

Accepted Answer

Quality architectural (dimensional laminate) asphalt shingles installed with proper ventilation and ice-and-water shield can last 20–35 years in Montreal's climate. 3-tab shingles have a shorter lifespan of 15–20 years. IKO Dynasty® shingles carry a manufacturer warranty and are rated for up to 220 km/h wind resistance. Lifespan is significantly affected by attic ventilation — improper ventilation accelerates shingle degradation from both heat buildup in summer and ice dam formation in winter. Visit /services/roofing/shingle for full product details.

Question 20

What shingle brand is best for Quebec climate?

Accepted Answer

For Montreal's climate, we recommend IKO Dynasty®, IKO Cambridge®, or BP Mystique 42™ as primary options. IKO Dynasty offers the highest wind resistance rating (220 km/h) and Nordic Seal technology designed for cold-climate self-sealing. BP Mystique 42 uses SBS-modified asphalt for superior cold-temperature flexibility — critical for Quebec winters. We also install GAF Timberline HDZ, CertainTeed Landmark, and Owens Corning Duration. Each product is evaluated against your specific project conditions — roof slope, exposure, and budget. See our full product lineup at /services/roofing/shingle.

Question 21

How much does shingle roof replacement cost in Montreal?

Accepted Answer

Residential shingle roof replacement in Montreal typically costs $4.50–$9.00 per square foot installed, depending on roof complexity, pitch, access, existing layers, and material selection. A standard 1,500–2,000 sq ft bungalow shingle replacement typically falls between $8,000–$18,000 fully installed including tear-off, ice-and-water shield, underlayment, drip edge, new shingles, and debris removal. Complex roof geometries, steep pitches, and extra layers increase cost. We provide free line-item estimates — call (438) 808-1103.

Question 22

What is IKO Dynasty and why do you recommend it?

Accepted Answer

IKO Dynasty® is IKO's premium architectural shingle line — designed specifically for performance in demanding climates like Quebec. Key features include True Square Advantage sizing (larger coverage per shingle), a wider ArmourZone® nailing surface for secure installation, Nordic Seal self-sealing technology that performs in cold temperatures, Class 3 impact resistance against hail, and wind resistance up to 220 km/h. Dynasty is available in 25+ enhanced colour blends and may increase resale value. It is the shingle we most often recommend for replacement projects across Montreal. Full details at /services/roofing/shingle.

Question 23

How do I know if I need a new roof vs. repair?

Accepted Answer

Repair is appropriate when: damage is isolated (single storm event, limited area), the overall shingle is under 15 years old, and the underlying deck is intact. Full replacement is appropriate when: shingles are 20+ years old, granules are consistently collecting in gutters, shingles are curling or cupping across large areas, you have multiple independent leak points, the decking is compromised, or you have had multiple repairs that have not held. If you have ice dam issues, that points to a ventilation problem that replacement alone will not solve — we evaluate both simultaneously. Contact us for a free honest assessment at (438) 808-1103.

Question 24

What causes ice dams and how can I prevent them?

Accepted Answer

Ice dams form when heat escapes from the living space through an under-insulated attic, warming the roof deck and melting snow. The meltwater flows to the cold eaves, refreezes, and creates a wall of ice that forces water back under shingles. Prevention requires: (1) Adequate attic insulation (minimum R-40 in Quebec). (2) Proper attic ventilation — balanced intake and exhaust. (3) Ice-and-water shield at eaves extending at least 900mm beyond the interior wall line. All three components are code requirements in Quebec. A new roof installation without fixing the insulation/ventilation problem will not eliminate ice dam issues.

Question 25

How many layers of shingles can a roof have?

Accepted Answer

Quebec building code and most municipal building departments allow a maximum of two layers of asphalt shingles (one re-roof over an existing layer). Beyond two layers, the weight becomes structurally problematic and a complete tear-off is required. We always inspect the existing shingle count and deck condition before proposing an overlay. Even when an overlay is technically permissible, we often recommend full tear-off to properly inspect the decking, install fresh ice-and-water shield, and address any structural issues — providing a longer-lasting and higher-quality final result.

Question 26

What is the difference between 3-tab and architectural shingles?

Accepted Answer

3-tab shingles are a single layer of asphalt with three uniform cutouts along the bottom edge — creating a flat, repetitive appearance. They are lighter and less expensive but have shorter lifespans (15–20 years) and lower wind resistance. Architectural (dimensional laminate) shingles are constructed with two bonded layers of asphalt, creating a textured, dimensional appearance that mimics natural wood shake or slate. They are heavier, more wind-resistant (up to 220 km/h on premium models), and last longer (25–35 years with proper installation). We recommend architectural shingles for all replacement projects — the cost difference is modest, the performance difference is significant.

Question 27

Does a new roof increase home value?

Accepted Answer

Yes, consistently. A new roof is one of the highest-ROI home improvements in the Montreal market. Buyers and inspectors immediately flag an aging roof as a major negotiating point — and for good reason. A professionally installed IKO architectural shingle or elastomeric membrane replacement with proper documentation signals building integrity and removes the largest exterior maintenance concern from a buyer's mind. According to industry data, roofing replacement typically recovers 60–80% of its cost in resale value — and in a competitive market, it can be the difference between a listing that sits and one that sells quickly at asking price.

Question 28

How much does a kitchen renovation cost in Montreal?

Accepted Answer

Kitchen renovation costs in Montreal range widely depending on scope: cosmetic updates (new cabinet doors, countertops, paint, hardware) typically run $10,000–$20,000. A mid-range full renovation with new cabinetry, countertops, tile backsplash, and appliance upgrades runs $25,000–$55,000. Premium renovations with custom millwork, structural changes, high-end stone, and luxury appliances typically exceed $60,000. Every project at CCC is quoted with full line-item transparency — no lump sums, no surprises. Visit /services/interior-renovation/kitchen for detailed information on what each scope includes.

Question 29

How long does a kitchen renovation take?

Accepted Answer

Most kitchen renovations at CCC take 4–8 weeks from demolition to completion. A simple cosmetic refresh without structural changes can be completed in 2–3 weeks. Projects requiring custom cabinetry (typically 4–6 weeks lead time from cabinet manufacturer), structural wall changes, new electrical panel work, or plumbing relocation typically run 8–14 weeks. We provide a detailed room-by-room timeline in every proposal. Sequencing is planned to maintain access to essential kitchen functions as long as possible during the renovation. Learn more at /services/interior-renovation/kitchen.

Question 30

How much does a bathroom renovation cost in Montreal?

Accepted Answer

Bathroom renovation costs in Montreal: a cosmetic refresh (new fixtures, vanity, tile over existing tile) runs $8,000–$18,000. A full gut renovation with new waterproofing, tile, shower, vanity, and fixtures typically runs $20,000–$40,000. Luxury renovations with heated flooring, freestanding soaker tub, custom tile work, steam shower, and premium fixtures typically exceed $45,000. Master ensuites cost more than standard bathrooms due to size and finish expectations. Every project is quoted with complete line-item detail. Visit /services/interior-renovation/bathroom for full scope descriptions.

Question 31

How long does a basement finishing project take?

Accepted Answer

A standard basement finishing project — framing, insulation, drywall, electrical, flooring, and basic finishes — typically takes 6–10 weeks for a 600–1,000 sq ft space. Adding a bathroom rough-in adds 1–2 weeks and requires a plumbing permit. Complex projects involving egress windows, legal secondary suite configurations, or extensive custom work can run 10–16 weeks. We provide phase-by-phase timelines in all proposals. Permit approval time (if required) is separate from construction time and varies by municipality. Full details at /services/interior-renovation/basement.

Question 32

Do I need a permit for interior renovations in Montreal?

Accepted Answer

It depends on the scope. Cosmetic updates — paint, cabinet replacement, flooring, fixture replacement at existing locations — generally do not require permits. Work that does require permits in Montreal: moving or removing load-bearing walls, adding or relocating electrical circuits or panels, relocating plumbing (toilets, sinks, showers), adding new bathrooms, finishing basements with new bedrooms or bathrooms, and adding egress windows. We research permit requirements for every project during the estimate phase and manage the full application process as part of our service. Never skip permits — they protect you at resale and with your insurer.

Question 33

Can you renovate while the home is occupied?

Accepted Answer

Yes — in most cases. We sequence work carefully to maintain access to essential areas and minimize disruption to daily life. For kitchen renovations, we typically set up a temporary kitchen (microwave, mini-fridge, coffee maker) in another room and keep plumbing functional as long as possible before the final connection phase. For bathrooms, we work floor by floor and maintain access to at least one functional bathroom at all times in multi-bathroom homes. We discuss phasing in detail during the estimate so you know exactly what to expect week by week throughout your project.

Question 34

Do you handle all trades or do I need to hire separately?

Accepted Answer

We are a full general contractor — we manage all trades under one contract. This includes demolition, framing, electrical, plumbing, HVAC modifications, drywall, tile, flooring, painting, and finishing. You have one point of contact from estimate to final walkthrough. You never need to coordinate multiple separate contractors, manage scheduling conflicts between trades, or worry about accountability gaps. All subcontractors we use are CCQ-compliant and RBQ-licensed in their respective trades. This single-point-of-accountability model is a core reason clients choose CCC. Visit /services/interior-renovation for our full scope.

Question 35

How does your estimate process work?

Accepted Answer

Our estimate process has three steps: (1) Initial contact — you reach us by phone at (438) 808-1103, through the contact form at /contact, or through any area page. We respond within 2 business hours. (2) Site visit — we schedule a visit to assess your project in person. We review scope, materials, existing conditions, and any structural considerations. (3) Written estimate — within 24 hours of the site visit, you receive a detailed line-item estimate broken down by trade and phase. No lump sums, no hidden items. You approve every line before any work begins. All estimates are free with no obligation.

Question 36

How quickly can you start a project?

Accepted Answer

Project start timing depends on our current schedule and project type. For emergency roof repairs, we respond immediately and begin triage work as quickly as possible — often same-day or next-day. For planned roofing projects, typical lead time is 1–3 weeks depending on season (summer is peak season for exterior work). For interior renovations, typical lead time is 2–6 weeks depending on scope and permit requirements (if applicable). We are transparent about our scheduling availability during the estimate phase. Contact us at (438) 808-1103 or /contact to discuss timing for your project.

Question 37

Do you require a deposit?

Accepted Answer

Yes. We use a simple two-payment structure. A 50% deposit is due on the arrival of materials and the first day of work — this covers material procurement and mobilization. The remaining 50% is due upon completion of the contract, once all work is finished to your satisfaction. This structure protects both parties: you are never paying for work that has not started, and we are covered for material costs before the project begins. We do not request 100% payment upfront — that is a significant red flag with any contractor.

Question 38

What payment methods do you accept?

Accepted Answer

We accept e-transfer, cheque, and major credit cards. E-transfer is the most common payment method for our clients. We provide itemized invoices for each milestone payment that align exactly with the work completed. All payments are documented and receipts provided promptly. We do not accept cash-only arrangements — proper documentation of payments protects you as a homeowner for warranty claims, tax purposes, and at time of resale.

Question 39

Can I see examples of your past work?

Accepted Answer

Yes. You can view project photos and videos across several platforms: our Facebook page features completed project galleries, our YouTube channel at youtube.com/@C-C-Construction includes project walkthroughs and technical breakdowns, and our Yelp profile features verified client reviews alongside project photos. During your estimate meeting, we can also show you photos of recent projects similar to yours in scope and neighbourhood. Client references are available upon request for projects over a certain value — ask us at time of estimate.

Question 40

What happens if unexpected problems are found during a project?

Accepted Answer

Montreal homes contain surprises — hidden rot, asbestos-containing materials, knob-and-tube wiring, unknown plumbing configurations, and structural issues that only appear during demolition. Our protocol: we stop work immediately when we discover something outside the original scope, document it thoroughly with photos, and present you with options and associated costs before proceeding. Nothing proceeds without your written approval via a formal change order. We never assume verbal approvals or proceed on our own judgment when your money and your property are at stake. This transparency is a core operating principle.

Question 41

How do I prepare my home for a renovation project?

Accepted Answer

We provide a detailed preparation checklist specific to your project during the pre-construction meeting. General guidelines: clear the work area of furniture, art, and valuables. For kitchen renovations, set up a temporary kitchen and remove items from cabinets. For basement finishing, remove all stored items from the basement. For roofing, remove fragile items from the attic and be aware that vibration from installation may affect the interior. Arrange for pet containment during active construction days. Inform neighbours about the project scope and expected duration — especially relevant for roofing. We handle all site protection and daily cleanup.
