Picking a window cleaner comes down to a few checks you can run in one phone call. Work through these eight checks, then compare quotes on equal terms, and you can judge any crew in Kitchener, Waterloo, Cambridge or Guelph for yourself.

What a good match looks like for your house
Start with your own house. The right company for a bungalow with clear access is not automatically the right one for a three-storey home with divided-pane windows and a hard-water problem. Write down what you need: how many windows, how many storeys, inside and outside or outside only, whether screens and tracks are included, and whether sprinklers have spotted the glass.
Then hold every company you consider to the same checklist. It works across the whole region, it does not go stale when a company changes owners or crews, and it keeps you comparing facts instead of star counts.
Eight checks to run before you compare prices
- Liability insurance. Ask for a certificate, not a verbal yes. It should show general liability cover and be current. A cracked pane or a scratched car is far easier to sort out when insurance is in place.
- WSIB coverage. Ask how the crew is covered if someone is hurt on your property. A current WSIB clearance certificate, or a clear answer about the company's coverage, is a fair request.
- Work-at-height training. Ontario has Working at Heights training for workers. It is not a homeowner requirement, but a company putting people on ladders should be able to say who holds it.
- Written scope. The quote should list what is included: outside, inside, screens, tracks, sills, skylights and basement windows.
- Method. Pure-water poles, hand washing with a squeegee, or a mix of both are all normal in the trade. What matters is that the company can explain how it handles the mineral spotting that hard groundwater causes in Waterloo Region and Guelph.
- Access plan. A good answer covers ladder placement, how gardens and lawns are protected, and what happens if a window cannot be reached safely.
- Independent reviews. Read reviews on platforms the company does not control. Start with the low-star ones and see how the company replied.
- Cleanup and fixes. Ask what happens if a spot is missed or something is damaged, and how you report it.
Send these questions by email if you can. The replies become a written record, and a company that answers plainly and quickly is telling you something about how the job itself will go.

How to read a written quote line by line
A useful quote is short but specific. Look for these lines, and ask for any that are missing.
- The number of windows and glass doors, and how many are above the ground floor.
- Which sides of the glass are covered: outside only, or inside as well.
- Whether screens, tracks and sills are included.
- Any extras by name, such as skylights, basement windows and glass railings.
- The price, the payment terms and what would change the price.
- The date, the arrival window and what happens in bad weather.
Collect three quotes if you can, then rewrite each one on the same scope before you compare. A quote far below the others usually leaves something out, or plans to add it later.
Red flags that cost homeowners later
- A price over the phone with no questions about the house.
- Hesitation about showing insurance or explaining crew coverage.
- A large deposit, or pressure to decide on the spot.
- No business address and no way to reach anyone after the job.
- Whole-house pricing with no count of windows.
- Ladders leaning straight on gutters, or crews trampling flower beds with no protection.
One red flag is a reason to ask more questions. Two are a reason to move on to the next quote.
Where D&D fits, so you can test it against the same list
D&D Home Services was founded in 2018 and is based in Kitchener-Waterloo. It carries $2 million in general liability insurance, its crew members are Working at Heights certified, and quotes are free and confirmed in writing before work begins. Window cleaning starts from $125 for typical local homes, and the company serves Kitchener, Waterloo, Cambridge, Guelph and nearby towns.
Put those claims through the checks above, the same as you would for anyone else. For more on weeding out weak contractors, read how to spot a bad exterior cleaning contractor. To see what a visit involves, start with window cleaning.
Key Takeaways
- Ask for insurance and WSIB paperwork, not a verbal yes.
- Insist on a written scope that names the sides of the glass, screens, tracks, sills and extras.
- Ask how a cleaner handles hard-water spotting, since pure-water poles and hand squeegee work are both normal methods.
- Read the low-star independent reviews and the company's replies before you compare prices.
