Whether you call it window washing or window cleaning, the result homeowners want is the same: streak-free, crystal-clear glass that lets natural light flood every room. If you are searching for professional window washing in Ottawa, this guide covers what the service includes, what to look for in a company, and how to get the most value.
Window Washing vs Window Cleaning: Is There a Difference?
There is no practical difference. “Window washing” and “window cleaning” refer to the same professional service. Some Ottawa homeowners use “washing” because it feels more descriptive of the wet cleaning process. Others use “cleaning” as the broader term.
Both terms describe the same process: removing dirt, water spots, pollen, and film from glass surfaces using professional tools and techniques. WindowGuru uses purified water systems and professional-grade squeegees for both interior and exterior glass.
What Is Included in Professional Window Washing in Ottawa
A thorough window washing service goes beyond just wiping the glass. When you book with WindowGuru, every visit includes:
- Exterior glass: All exterior windows cleaned, including hard-to-reach second and third-storey panes using water-fed pole systems.
- Interior glass: Each window cleaned from inside the home with protective drop cloths to protect your floors and furniture.
- Frames, tracks, and sills: Dirt, insects, and debris removed from every window track and sill.
- Screen washing: Screens removed, hand-washed, dried, and reinstalled.
- Spot treatment: Hard water stains, paint overspray, and stubborn mineral deposits treated with specialized products.
The result is not just clean glass, but clean frames and tracks that help your windows operate smoothly and seal properly.
How Often Should Windows Be Washed in Ottawa?
For most Ottawa homes, twice a year delivers excellent results. The ideal schedule is:
- Spring (April or May): Removes the heavy layer of winter salt spray, road grime, and mineral runoff.
- Early fall (September or October): Clears summer pollen, dust, and organic matter before winter.
Homes near busy roads such as Carling Avenue, Bank Street, or Highway 417 accumulate grime faster and may benefit from quarterly washing. The same applies to homes near ongoing construction in rapidly developing areas.
What Ottawa Homeowners Should Look for in a Window Washing Company
Not all window washing services deliver the same quality. Before hiring, verify:
- Insurance and WSIB: The company should carry both general liability insurance and WSIB coverage. If an uninsured worker is injured on your property, you could be held liable.
- Google reviews: Look for a track record of consistent five-star reviews. WindowGuru has earned 271+ reviews at a 5.0 average, the highest rating among Ottawa window washing providers.
- Written quotes: Get pricing in writing before the appointment. This prevents surprise charges on the day of service.
- Interior and exterior service: Some companies only wash exterior glass. For a complete result, choose a company that handles both sides.
- Bundling options: Companies like WindowGuru that also offer gutter cleaning, siding cleaning, and softwash cleaning can save you money by combining services into one visit.
How Much Window Washing Typically Costs in Ottawa
Pricing varies based on home size, number of windows, and accessibility. Typical Ottawa ranges for 2026:
- Small home (15-20 windows): $180 to $280
- Average home (25-35 windows): $280 to $400
- Large home (40+ windows): $400 to $600+
Interior-and-exterior cleaning costs more than exterior-only, but the value is significantly better because interior surfaces accumulate fingerprints, cooking film, and condensation residue that exterior cleaning cannot address.
When to Bundle Window Washing with Other Services
The most cost-effective approach for Ottawa homeowners is to combine window washing with complementary exterior cleaning services on the same visit:
- Windows + gutters: The most common combo. The crew is already using ladders, so gutter cleaning adds minimal setup time.
- Windows + siding: If your siding is showing green algae, oxidation, or general dullness, combining with a siding wash refreshes your entire home exterior.
- Full exterior package: Windows, gutters, and siding cleaned in a single visit. This is our most popular residential package at WindowGuru.
How to Get Streak-Free Results That Last Longer
Professional window washing already delivers streak-free results, but you can extend the clean between visits:
- Adjust sprinklers so they do not spray window glass (mineral deposits from irrigation water are the top cause of spotting)
- Trim overhanging branches that drip sap or drop debris onto windows
- Keep window screens clean. Dirty screens transfer grime to glass every time it rains
- Avoid cleaning windows in direct sunlight. The glass dries too fast and leaves streaks
