How We Approach Window and Door Installation
Windows and doors are the most vulnerable part of your home's envelope. They need to be installed with focused care to protect against infiltration from the wet weather the Mid Island region is known for.
As general contractors, we understand this is a critical part of a system. We take the time to ensure the framing, positioning, insulation, flashing, and finishing all come together to protect your home from the harshest conditions.
What clients say
Jason R. — Major Home Renovation (Including Exterior French Door Installation)
Recommends on Facebook
"We hired Clarity Contracting for a major renovation after meeting with several companies. From the start we felt they were not only the most detailed in their quote but the most committed to the success of the project. As with any renovation, there were a few bumps and surprises along the way, but they worked through them with us, ensuring we were always on the same page. Communications were clear."

"Hired them for several projects: exterior window and door replacement; design and renovation of a bedroom suite combining two rooms and creating a large walk-in closet within including wall and ceiling rough-in, insulation, and drywall; studding, insulation, and drywall of the complete upstairs and basement of a property, and the design and build of a large (16x26) chicken coop. All work was completed on time..."

What We Install
Window and door suppliers sell a product and installation is an afterthought- their crews are trained to swap a unit into an existing opening, not to do carpentry or framing work. If your opening needs to change, that's where they stop.
Clarity Contracting handles the complete scope. We supply and install windows and doors, and we can modify or relocate openings — larger sizes, new placements, structural changes — all included as part of the same job.
Our installs cover:
- Casement, sliding, double hung, and fixed windows
- Entry doors and patio doors
- Framing modifications for larger openings or new window locations
- Interior and exterior trim
- Caulking and air sealing
- Full finish carpentry — painted and ready
Window and door work often runs alongside larger projects. Whether you're planning a kitchen renovation in the Comox Valley, a bathroom renovation in Courtenay, general home improvements in Comox, or a deck build in Cumberland, we manage all project types across the Comox Valley and in Campbell River.

Questions worth asking
Are there rebates available for new windows in BC?
Yes, in many cases. BC's CleanBC Better Homes program offers rebates on energy-efficient windows and doors that meet specific performance thresholds. The amounts and eligible products change periodically — the current program details are at betterhomesbc.ca.
The practical advice: confirm rebate eligibility before selecting your product, not after. Some products qualify and some don't, and the rebate amount can meaningfully offset the cost difference between a standard and a higher-performance unit. Clarity Contracting can tell you which products are likely to qualify — but final eligibility should always be confirmed directly with the program before purchasing decisions are made.
How much does window replacement cost in BC?
Window replacement cost depends on the number of units, size, style, and how much work surrounds the window itself. The glass unit is only part of the price — interior trim, drywall repair, exterior casing, siding patches, and insulation all factor in depending on what the job requires.
A straightforward retrofit on a standard-size window typically runs $800 to $1,500 per opening installed, including finishing work. Full-frame replacements with framing changes cost more — plan for $1,500 to $3,000 per opening and up depending on complexity. A whole-home window replacement with framing modifications is a multi-thousand dollar project that should be estimated as a full renovation, not a per-unit calculation.
The variables are real. A precise number comes from a site visit and a written estimate, not a per-window average.
What should I know about framing changes when replacing windows?
If an opening needs to change size, the work goes well beyond swapping the window unit. Framing, siding, insulation, drywall, and trim all need to be addressed. Window and door suppliers are trained to swap a unit into an existing opening — not to do carpentry or framing work. Clarity Contracting handles the complete job, including any framing modifications, as part of the same project.
Do I need a permit to replace windows or doors?
It depends on what the job involves. A like-for-like replacement in the same opening typically does not require a municipal building permit. Enlarging an opening, relocating a window, or making structural changes to accommodate a new unit will trigger a permit requirement. Clarity Contracting handles the coordination — if your project needs permits, we'll tell you what's required and make sure the right ones are in place before work begins.
How long does window and door installation take?
A standard retrofit window replacement takes a few hours per window. A full-frame replacement with framing changes takes longer — plan for a full day or more per opening when structural work is involved. A complete whole-home window replacement with framing modifications is typically a multi-day project.
What is the difference between a retrofit and a full-frame window replacement?
A retrofit installs a new window inside the existing frame — faster and less expensive, and the right choice when the frame is in good condition. A full-frame replacement removes everything including the frame, jamb, and trim — required when the frame is rotted, damaged, or when the opening is changing size. Retrofit is not a cosmetic shortcut — it is the correct method when the existing frame is sound. Full-frame is the correct method when it isn't.
