5 Things to Look for When Hiring a Window Cleaning Company in Ontario

Quick answer: When hiring a window cleaning company in Ontario, verify they carry liability insurance, check for real local reviews, ask about their equipment and cleaning method, confirm they offer a clear written quote, and make sure they're experienced with your property type. Those five checks filter out most unreliable operators.

Most homeowners spend more time picking a paint color than vetting the crew they let onto their ladders. It's understandable, window cleaning feels low-stakes until something goes wrong. A broken screen, a scratched pane, or a no-show on the day you took the afternoon off can all be avoided with a little due diligence upfront.

Here's what to look for before you book.

1. Proof of Liability Insurance

This is the first question to ask, every time. A reputable window cleaning company in Ontario will carry general liability insurance, typically at least $2 million in coverage. It protects your property if something breaks and protects you if a worker is injured on your premises.

• Ask for a certificate of insurance before the job starts
• Check that the policy is current, not expired
• Confirm it covers both residential and the type of work being done

If a company hesitates or can't provide proof quickly, move on.

2. Genuine Local Reviews

Why "local" matters more than star count

A company with 50 detailed Google reviews from Oakville, Burlington, or Mississauga homeowners tells you far more than a generic 5-star rating. Look for reviews that mention specific things: streak-free results, punctuality, how they handled a tricky second-storey job.

• Check Google Business Profile reviews first
• Look for recent reviews, not just volume
• Watch for how the company responds to negative feedback
• Be skeptical of profiles with only 5-star reviews and no written comments

3. Professional Equipment and a Clear Cleaning Method

What should a good window cleaning setup actually look like?

A professional company should be able to explain exactly how they clean your windows. Blondie's Window Services uses a purified de-ionized water system delivered through a water-fed pole. De-ionized water has had all minerals removed, so it dries completely clear without leaving spots or residue.

• Water-fed pole systems are safer for multi-storey homes (less ladder work)
• Purified water leaves no mineral deposits or streaks
• For interior windows, squeegee and lint-free cloth technique still applies

If a company just shows up with a bucket and dish soap, that's worth knowing ahead of time.

4. A Written Quote With Clear Scope

Verbal quotes are easy to misremember. A written quote protects both you and the company. It should spell out exactly what's included.

• Number of windows and which floors
• Whether screens, tracks, and sills are included or extra
• Interior vs. exterior, or both
• Any add-ons like skylights or French panes

Pricing in Ontario typically ranges by home size and job complexity. Getting two or three quotes lets you spot outliers in either direction.

5. Experience With Your Property Type

Does the company work on homes like yours?

A crew that mainly does high-rise commercial buildings may not be the right fit for a heritage home in Markham with wood-framed windows. Ask whether they regularly work on residential properties in your area, whether that's a detached home in Vaughan, a townhouse in Etobicoke, or a condo in Toronto.

• Ask for examples of similar jobs they've completed nearby
• Check if they know how to handle specialty glass or older window frames
• Confirm they're familiar with the access challenges at your property
