Steve Vukosavljevic

Great experience from start to finish! The team was professional, on time, and did excellent work. The windows and patio door look amazing, fit perfectly, and have already made a big difference. Highly recommend! Thank you Kyle!

Janine Krieger

Kyle and his KNR crew were amazing. Professional, great service, work done in a timely fashion. His knowledge of his products and guidance in choosing the windows and doors were perfect. Highly recommend.

Nicole Griffiths

Kyle came and quoted us for our front window and quickly got the order in, it came early which was a good surprise and he came out to install it for us. The work was done meticulously and quickly leaving us with a beautiful new front window as well as some capping around our front door. We now have a safe and efficient window (instead of one that was rotting and also apparently homed a nice sized bee hive). Kyle is professional, quick and reliable and we are thankful for his handiwork. We will be having him return for additional work in the near future.

Ray Serifi

I have had nearly all my homes windows replaced by KNR and am extremely happy with the service. Kyle and his crews are punctual, arrive when scheduled, neat while performing installation and very informative during the process. I would highly recommend KNR to my family and friends.

Michelle Cassidy

Kyle did an amazing job. He's very professional and so easy to deal with. I could tell Kyle takes pride in his work and makes sure its done properly. It's absolutely worth giving him a call. We'll be contacting him again to do our other windows. Thanks for our new look. We absolutely love it!!

Before you hire a window and door installer in Ontario

No provincial licence is required. Installation quality is governed by manufacturer specification and the Ontario Building Code rather than by a trade certificate.

General liability insurance and WSIB clearance

Standard checks. Window installation involves ladder work and heavy glass.

Manufacturer-trained installer status

Matters more than usual here, because most window warranties are voided by installation that departs from the manufacturer specification.

Building permit for new or enlarged openings

Replacing a window in an existing opening generally does not need one. Cutting a new opening, or enlarging one for a basement egress window, generally does.

Verify with: Your municipal building department confirms what your specific job requires.

ENERGY STAR certification for the product

Relevant if you intend to claim any efficiency rebate, which typically requires certified products and documentation.

Questions worth asking

  • Is this a retrofit or a full-frame installation? What would the other one cost?
  • How is the gap between the window and the rough opening insulated and air-sealed?
  • Is exterior capping included, and in what colour and material?
  • Is the warranty on the glass seal, the frame, and the labour - and are they different lengths?
  • Is the warranty transferable if I sell the house?
