What does a post-construction cleaning company in Ottawa charge for window cleaning add-ons?

Window cleaning after construction in Ottawa typically costs between $200 and $1,500 as an add-on service, depending on the number of windows, their size, accessibility, and the amount of construction residue that needs removal. This pricing reflects the specialized nature of post-construction window cleaning, which goes far beyond regular residential window washing.

Post-Construction Window Cleaning Complexity

Construction window cleaning requires removing paint overspray, adhesive residue, concrete splatter, drywall dust film, and protective tape residue that accumulates during building or renovation work. Standard residential window cleaning costs $3 to $8 per window in Ottawa, but post-construction window cleaning runs $8 to $25 per window because of the additional time and specialized solvents required. Large picture windows or floor-to-ceiling glass can cost $40 to $80 each when heavily contaminated with construction debris.

The biggest cost factor is accessibility. Ground-floor windows are straightforward, but second-story windows, skylights, or windows above extensions require ladders or scaffolding, which increases labor time and safety requirements. Interior window cleaning during post-construction work often costs more than exterior cleaning because construction dust settles on interior glass surfaces in layers, and the fine particulate bonds to glass when mixed with humidity from drywall compound and paint curing.

Ottawa's extreme winter conditions affect post-construction window cleaning pricing and timing. Windows cleaned during heating season (October through April) accumulate static electricity from low humidity, attracting fine dust particles that require multiple cleaning passes. Professional cleaners use anti-static solutions and microfiber cloths specifically designed for construction dust removal. Summer cleaning is more efficient because higher humidity reduces static buildup, but surfaces must be cleaned before direct sunlight hits wet glass to prevent streaking.

Professional post-construction window cleaning is essential because construction debris particles act like sandpaper when dragged across glass with standard cleaning cloths. Homeowners attempting DIY window cleaning after construction frequently scratch new windows permanently, creating damage that costs hundreds or thousands of dollars to repair. Professional cleaners use glass-safe solvents, razor blade techniques for removing paint spots, and lint-free cloths that won't scratch.
