Serving Ontario

About the company

Windows and doors work for Ontario homes and small commercial spaces

QTSHUB Windows & Doors replaces, installs, and repairs windows and doors. We look at the opening, say what it needs, and quote that work in writing. Our office is in Kingston. We serve customers across Ontario.

How the company works with people

Most clients find us when something in the house has become annoying or unsafe: a window that fogs, a door that does not lock, or glass that has broken. They do not need a lecture. They need someone who will come, measure, and explain the difference between a glass repair and a full replacement.

When you call +1 (613) 634-3422 or email [email protected], you reach QTSHUB Windows & Doors. You can also send an estimate request from the contact page. An estimate request is not a confirmed appointment.

Our office is at 616 Gardiners Rd, Kingston, ON K7M 9B8. Property visits are scheduled. If you want the list of what we take on, the services page is the complete version. The order of a job is on how we work.

What we value

The standard we hold the work to

Say what is wrong

If a pane can be replaced, we say that. If the frame is finished, we say that too. The recommendation follows the condition of the opening.

Write it down

Quotes name the openings, the product direction, and the price. You should not have to reconstruct the agreement from a text message.

Respect the house

Floors, furniture, and landscaping are part of the job site. We plan the work so the opening is protected and the area is left tidy.

Stay reachable

After-sales questions can use the same phone number listed on this site.

Who the work is for

Homeowners are the core of the schedule: houses and townhomes across Ontario. Small commercial clients are welcome when the openings are a similar scale, such as an office entry, a clinic window, or a modest shop lite.

Common reasons people call include failed seals, sills that hold water, patio doors that no longer glide, and units that were installed without enough attention to the gap around the frame.

We do not publish awards, ratings, or certifications on this site. Read the privacy policy if you want to know how call and form details are handled.

Talk to the company

Start with the opening, not a script
