Why Oshawa Windows Need Professional Cleaning
- GM plant industrial residue — decades of automotive manufacturing left Oshawa with airborne particulate that settles on glass surfaces, especially south of the 401
- 401 highway salt and road spray — Oshawa runs right along the 401. Homes within 2km get coated in road salt mist from November through April
- Lake Ontario humidity — the lake sits just south of the city. Constant moisture accelerates mineral deposit buildup on glass
- Oshawa Creek valley pollen — the creek corridor and conservation areas produce heavy spring pollen loads that coat every exterior surface
- Durham Region hard water — local tap water leaves mineral deposits on glass when sprinklers or rain hit windows. Our ClearCoat™ system eliminates this
- New construction dust — north Oshawa is booming with new developments around Taunton and Windfields. Construction dust travels kilometres

Frequently Asked Questions
How much does window cleaning cost in Oshawa?
Professional window cleaning in Oshawa ranges from $179 for a bungalow to $749+ for large homes with interior and exterior service. Most 2-storey detached homes cost $249 to $399 for exterior cleaning. Bundle with gutter cleaning to save $50, or add pressure washing too and save $75.
Which areas of Oshawa do you serve?
We serve all of Oshawa including Taunton, Windfields, Northwood, Samac, Eastdale, Pinecrest, Lakeview, Kedron, and all surrounding areas. We also serve Whitby, Ajax, and Pickering.
What is ClearCoat™ purified water?
Our multi-stage filtration system removes 100% of minerals from water. Durham Region tap water contains dissolved solids that leave white spots when water dries on glass. Our purified water (0mg/L TDS) dries crystal clear with zero streaks and stays cleaner 2-3x longer than traditional cleaning.
Do I need to be home during cleaning?
Not for exterior-only cleaning. We'll text you before and after with photos. For interior + exterior, someone needs to provide access. Many Oshawa customers leave a key or garage code.
How long does it take?
Most Oshawa homes take 1.5 to 3 hours depending on size and services. Bungalows are typically done in 90 minutes. We'll give you a time estimate when you book.
