Frequently Asked Questions
Everything Montreal homeowners ask us about hiring a general contractor, renovation costs, timelines and permits. Answered without the jargon.
General Contractor
A general contractor manages your entire construction or renovation project. That includes planning, budgeting, permit applications, hiring and supervising subcontractors, ordering materials, coordinating inspections and delivering the finished space. With Kasa General Contractor, you have a single point of contact from the first call to the final walkthrough.
In Quebec, renovation work valued at more than $2,000 generally requires an RBQ licensed contractor. Beyond the legal requirement, a general contractor saves you from juggling schedules, quotes and site issues across multiple trades. You get one accountable partner, a structured timeline, insurance protection and workmanship covered by a written warranty.
Search the contractor's name or licence number in the online registry of the Régie du bâtiment du Québec. Confirm the licence is active and covers the categories of work you need, then ask for proof of liability insurance. Kasa General Contractor holds RBQ licence 5797-3208-01, is an APCHQ member and carries $5,000,000 in liability insurance.
The process starts with a free 30 to 45 minute discovery call, followed by an on-site visit when the project warrants it. For major projects, we then prepare a detailed quote. You get precise numbers, not a vague ballpark.
A general contractor holds the contract with you and is responsible for the entire project: permits, schedule, budget and quality control. Subcontractors are specialists, such as electricians and plumbers, hired and supervised by the general contractor to complete specific portions of the work. You never have to source or manage them yourself.
Renovations in Montreal
We deliver turnkey residential renovations, kitchen remodeling, bathroom remodeling, home extensions, commercial construction and post-disaster reconstruction. Our team serves Montreal, the West Island and the South Shore, and works in English, French and Spanish.
As a guideline, a bathroom renovation starts at around $25,000 and a kitchen renovation at around $40,000. Complete home renovations typically range from $80,000 to $600,000 depending on the size of the property and the scope of work. Every project receives a detailed quote before any work begins.
Verify the RBQ licence and insurance first, then look at completed projects, reviews and how detailed the quote is. A reliable contractor puts everything in writing, explains the schedule and communicates at every critical step. Be cautious with unusually low bids: they often hide exclusions that surface later as extras.
A bathroom renovation generally takes 3 to 6 weeks and a kitchen renovation 6 to 12 weeks. Home extensions run from 4 to 12 months once design and permits are included. We provide a detailed schedule at contract signing and keep you informed throughout the project.
Older Montreal homes can hide outdated wiring, plumbing or structural surprises behind the walls. When something comes up, we document it, explain your options and price the change in writing before proceeding. No additional work is done without your approval, so your budget stays under control.
House Remodeling
We handle complete house remodeling: open-concept conversions, kitchen and bathroom remodels, basement transformations, structural modifications and full interior reconfigurations. As a turnkey general contractor, we manage design coordination, permits and every trade required to deliver the finished space.
Yes, when it is done well. A kitchen remodel typically returns 60 to 80% of its cost in added resale value, and a bathroom remodel 50 to 70%. Beyond resale numbers, remodeling improves how your home works for your family every single day.
Labour is usually the largest single expense, and it climbs quickly when structural, plumbing or electrical work is involved. Moving load-bearing walls, relocating drains or upgrading wiring requires licensed specialists and inspections, which costs far more than surface finishes. That is why changing the layout of a space costs more than refreshing it.
It depends on the work and your borough. Cosmetic updates rarely need a permit, but structural changes, extensions and modifications to the building envelope generally do. We identify the permits your project requires and can submit the applications to the city on your behalf.
Renovation restores or updates a space without changing its purpose, think new flooring, cabinets or fixtures. Remodeling changes the structure, layout or function of the space, such as removing walls to create an open-concept kitchen or converting a garage into living space. Remodeling usually involves permits and structural work, which makes an experienced general contractor essential.
The role of a general contractor in your renovation
A general contractor is the single party legally and contractually responsible for your project from start to finish. Instead of hiring an architect, an electrician, a plumber and a cabinetmaker separately, you sign one contract and the contractor coordinates everyone: permits, drawings, schedules, deliveries, inspections and the final handover.
At Kasa General Contractor, that coordination is backed by 40 years of family experience in construction, 12 years as general contractors and more than 500 completed projects across Greater Montreal. Cristian and Samuel walk the site with you at every critical milestone, so decisions about partitions, electrical layouts and finishes are made together, never behind your back.

Common renovation projects in Montreal and their benefits
Kitchen remodeling remains the most requested project, and for good reason: a well-designed kitchen typically returns 60 to 80% of its cost in added resale value while transforming daily life at home. Bathroom renovations follow closely, recovering 50 to 70% of their cost and solving the plumbing and waterproofing issues common in older Montreal properties.
Home extensions deliver the biggest change in living space: second storeys, rear extensions, four-season sunrooms and garage conversions let growing families stay in the neighbourhood they love instead of moving. For properties that need work everywhere, a complete turnkey renovation modernizes the whole home in one coordinated project, with budgets typically between $80,000 and $600,000.
How to hire the right general contractor
Start with the paperwork: an active RBQ licence, proof of liability insurance and membership in a recognized association such as the APCHQ. These are not formalities, they are the protections that stand between you and an abandoned or defective job.
Then judge the process. A serious contractor asks detailed questions before quoting, visits the site, and delivers a written quote that itemizes the work rather than a single round number. Ask who will supervise your project, how change orders are handled and what warranty covers the workmanship. Kasa General Contractor answers each of these questions in writing, holds RBQ licence 5797-3208-01, carries $5,000,000 in liability insurance and backs its work with a 1 year labour warranty plus the RBQ guarantee plan.
Renovation permits in Montreal: what to expect
Permits in Montreal are issued by each borough, and the rules vary from one to the next. As a general rule, structural changes, home extensions, load-bearing wall modifications and changes to the building envelope require a permit, while purely cosmetic work usually does not. Processing times typically run 4 to 8 weeks, and longer in heritage sectors such as parts of Westmount and Outremont, where additional architectural review applies.
The good news: you do not have to navigate any of it alone. We prepare the drawings with our architects and technologists, submit the permit applications on your behalf and schedules the work around the approval timeline. It is one more reason to start with a free evaluation before committing to any plan.

Wonderful experience building our patio deck last fall. The job was done quickly with great attention to detail. Solid construction.
