How much does post-construction window cleaning cost for a new home in Ottawa?

Quotes for post-construction window cleaning on a new home in Ottawa can run roughly $200 to $1,500, depending on the number of windows, their size, accessibility, and how much construction residue has accumulated on the glass. A modest home with a standard window package will sit toward the lower end, while a large custom home with many windows, skylights, and a multi-storey design can land toward the top. Treat that as perspective and ask for itemized written quotes.

What Drives the Cost of Post-Construction Window Cleaning

The biggest factor is the type and amount of construction residue on the glass. New-build windows can accumulate a wide variety of contamination during the construction process, including drywall dust film, paint overspray, stucco or mortar splatter, adhesive residue from protective films, silicone smears from caulking work, and general construction grime. Each of these contaminants requires a different cleaning approach, and some, like dried mortar or silicone, demand specialized solvents and careful hand scraping with razor tools. A window that only has dust film is quick to clean, while one with dried stucco splatter needs much more careful detail work.

Accessibility is the second major cost driver. Ground-floor windows are straightforward, but second and third-storey windows require extension poles, ladders, or even scaffolding. Two-storey designs with large picture windows and transom windows above entryways can require specialized reach equipment. Skylights can add cost because they may need interior scaffolding or a platform to reach safely.

Window cleaners may charge per window, per pane, or a flat rate. Larger picture windows, patio doors, and floor-to-ceiling units usually cost more than standard double-hung or casement windows. Some companies offer flat-rate packages for new builds, which can provide better value than per-window pricing for homes with many windows. Always confirm whether the quote includes both interior and exterior cleaning, as some companies price these separately.

Post-construction window cleaning is tricky to tackle yourself on a new build. Glass can be scratched by construction debris particles, and using the wrong cloth or technique can cause permanent damage, so check your window manufacturer's care instructions before anyone cleans the glass. Experienced cleaners may use purified water systems, glass-safe solvents, and proper razor techniques to remove construction residue without scratching.
