What is the cost of cleaning a newly finished attic conversion in my Ottawa home?

Post-construction cleaning for a newly finished attic conversion in Ottawa typically costs between $600 and $1,800, depending on the size and complexity of your conversion. The unique challenges of attic cleaning—including sloped ceilings, limited access, and the fine dust that accumulates in these enclosed spaces during construction—require specialized equipment and techniques that affect pricing.

Attic Conversion Cleaning Specifics

Attic conversions present unique cleaning challenges that drive costs higher than standard room cleaning. The sloped ceilings and tight corners where walls meet the roofline trap construction dust that's difficult to reach with standard equipment. HEPA vacuuming is absolutely essential because the confined space means construction dust becomes highly concentrated and airborne particles settle into every crevice. Professional cleaners need specialized extension tools and often scaffolding or ladders to properly clean angled surfaces and skylights that are common in attic conversions.

Ottawa's extreme winter climate significantly impacts attic cleaning costs. If your conversion was completed during heating season, the bone-dry indoor air (often 15-20% humidity) means drywall dust and sawdust became exceptionally fine and pervasive. This dust infiltrates insulation gaps, settles behind knee walls, and gets drawn into any HVAC ducts serving the new space. Many attic conversions require dedicated duct cleaning at $300-600 additional cost because the new ductwork and increased air circulation spreads construction particles throughout your home's entire HVAC system.

Per-square-foot pricing for attic cleaning ranges from $0.75 to $2.25 in Ottawa, higher than standard room cleaning due to access challenges. A typical 400-square-foot attic conversion runs $800-1,200 for complete post-construction cleaning. Larger conversions of 600-800 square feet cost $1,200-1,800. If your conversion includes a new bathroom, add $200-400 for specialized fixture cleaning and grout haze removal from new tile work.

Timing affects your costs significantly. Spring cleaning demand in Ottawa drives prices up 15-25% as winter-delayed projects rush to completion. Summer cleaning is most efficient because lower humidity allows surfaces to dry quickly, but book early as this is peak construction season. Always get three written quotes and ensure they specify cleaning of all angled surfaces, skylights, built-in storage areas, and any new electrical fixtures or ceiling fans.
