Expert Window Installers in Port Coquitlam, BC
Did you know that up to 90% of window performance issues are caused by poor installation, not the window itself? The highest-quality energy-efficient window is useless if it is improperly shimmed, inadequately foamed, or poorly caulked. In the wet and windy climate of Port Coquitlam, installation shortcuts inevitably lead to drafts, condensation, and expensive wood rot inside your walls.
At Robertson Windows, we treat the installation process as the most critical step of your home improvement project. Unlike major big-box stores or volume-focused companies that farm out labor to the lowest-bidding sub-contractors, we rely entirely on our own in-house, factory-trained installation crews. This allows us to maintain strict quality control from the moment we pull into your driveway until the final bead of caulking is applied.
Our comprehensive installation service encompasses careful extraction of your old units, precision leveling, advanced multi-layer weatherproofing, and a spotless cleanup. Whether you need a standard retrofit installation or a complex full-frame tear-out in your Port Coquitlam home, we have the specialized expertise to ensure your windows perform flawlessly for decades—backed by an ironclad lifetime warranty.

Our Proven 6-Step Installation Process
We follow a strict, standardized installation protocol designed to maximize the lifespan, security, and efficiency of your new windows.
Site Preparation & Protection
We begin by protecting your home. Our crew lays down padded drop cloths, runners, and protective plastics over your floors and nearby furniture to prevent dust and damage.
Careful Extraction
Your old windows are carefully scored and removed to minimize any disturbance to your interior drywall, trim, or exterior siding. We instantly haul the old units out to our trucks.
Precision Fitting & Shimming
The new window is set into the opening. We use specialized shims and laser levels to ensure the unit is perfectly plumb, square, and level so it operates flawlessly for life.
Advanced Insulation
We apply high-quality, closed-cell low-expansion polyurethane foam around the entire perimeter gap. This creates a permanent, waterproof, and highly insulated thermal break.
Sealing & Trim
The exterior is sealed with premium, climate-resistant caulking and custom flashing to shed rain. Interior trim and casing are then re-applied or replaced to frame the window beautifully.
Final Walkthrough & Cleanup
We vacuum the work areas, clean the new glass, and perform a final inspection with you, demonstrating how to operate and maintain your new windows.
CleanBC & Federal Efficiency Rebates
Having your windows professionally installed by a certified company is often a requirement to qualify for significant eco-energy government rebates. Ask us how to qualify!
