It's the cheapest space to gain in a house — the structure is already there. The trick is finishing it properly, especially in the Chelsea hills.
Family room, home theatre, bedroom, bathroom, office or wet bar: we design and execute the entire project for Chelsea homeowners. Framing, insulation, soundproofing, electrical, plumbing, drywall, flooring and finishes — a single point of contact, from the plan to the last coat of paint.
Here, many homes are built on granite bedrock, often with a walk-out basement that already brings good natural light and a door to the yard. We account for that from the plan onward. The home consultation is free with no obligation.

Finishing a basement means coordinating half a dozen trades: framer, electrician, plumber, drywaller, painter, flooring installer. On your own, it's a scheduling and accountability headache. We handle it all, in the right order, with one accountable team and one fixed price.
No contractors pointing fingers when something goes wrong. One plan, one schedule, one contract — and a cohesive result from start to finish.

A beautiful basement built over a moisture or radon problem is money thrown away. Before the first stud goes up, we assess the basement: rock seepage, condensation, drainage. We install an air-gap dimpled membrane, proper insulation and vapour barrier, and plan dehumidification where needed.
In Chelsea, building on granite bedrock also means radon is a real local concern: we recommend a test and can integrate sub-slab depressurization during the finish. The Verano team is on site, supervised by Pierre-Michel Légaré. RBQ-licensed and insured.
We finish basements throughout the municipality: Old Chelsea, Farm Point, Mont-Cascades, Burnett, as well as Wakefield and the La Pêche area. A recent build with high ceilings or a cottage on rock with a walk-out basement — we fit the plan to your space, your lot and your budget, keeping in mind that the permit goes through the MRC des Collines-de-l'Outaouais.

The price depends on the square footage, whether you add a bathroom or wet bar, the number of rooms and the level of finish. It's almost always cheaper than adding space above grade because the structure is already there. We travel to Chelsea for free to assess the project and give you a fixed turnkey price with no surprises.
Yes. In Chelsea the renovation permit goes through the MRC des Collines-de-l'Outaouais, not the City of Gatineau. If you add a bedroom, the Building Code requires a compliant egress (emergency-exit) window — and Chelsea's walk-out basements often already provide the door and natural light you need. We handle the permit application and make sure everything is compliant before, during and after the work.
Many homes in the Chelsea hills are built on granite bedrock, and granite is a natural source of radon. We recommend a radon test before finishing, and we can integrate sub-slab depressurization during the finish to vent the gas. On moisture, here it's less about clay and more about rock seepage and condensation: we manage the seepage, install an air-gap dimpled membrane, proper insulation and vapour barrier before we finish.
We manage the whole project and coordinate our licensed electricians (CMEQ members) and plumbers (CMMTQ members). You sign one contract and deal with one responsible contractor, from the plan to the last coat of paint. Most Chelsea homes are on well and septic, and we account for that in the plumbing. The specialized work is done by licensed professionals and is Code-compliant.
Most basements are finished in 4 to 8 weeks depending on scope — a bathroom, a wet bar or several rooms extend the schedule. Because one contractor coordinates framing, electrical, plumbing, drywall and finishes, you avoid the delays between subcontractors. We give you a precise schedule before we start.
Yes. A legal bedroom needs a code-compliant egress window — an advantage with a walk-out basement, since the door and light are often already there. A bathroom needs proper drainage (sometimes a sewage-ejector pump if the basement sits below the sewer line). We plan both from the start so the layout is compliant and functional.
