The owner at Raven Window made the whole process of ordering my new door super easy. They took the time to explain everything clearly and helped me choose the right option for my home. Great communication and service so far can’t wait to see the finished result!

Absolutely do not waste your money buying these!! The doors leak so much air and the condensation is terrible, Raven & Reynaers have both been out multiple times to fix and adjust them just to have the same results. I will say they have helped me as much as they can but I still have tons of problems that I don’t see going away. I have waited a very long time to review these cause I wanted to love them so bad and now I’m just totally unimpressed.

As a builder based in the U.S., I have had the pleasure of working with Raven Windows on my last four projects, and I cannot recommend them highly enough. The level of customer service and the quality of their products is truly exceptional. Every interaction with their team has been seamless, professional, and incredibly supportive. One of the standout qualities of Raven Windows is their attention to detail and willingness to collaborate. They consistently offer valuable design suggestions and practical advice on what will work best for each unique project. Their expertise has been instrumental in ensuring that the final results are not only aesthetically stunning but also functionally sound. The quality of their windows and doors is unmatched. Raven Windows' products are modern, durable, and versatile, accommodating a wide range of design preferences. It’s rare to find a company that combines innovative products with such a high level of craftsmanship and reliability. Finding Raven Windows has been a game-changer for my business. They’ve quickly become a trusted partner, and I look forward to working with them on many more projects in the future. If you're seeking exceptional products and a team that truly cares about your project's success, I highly recommend Raven Windows.

I’ve had the opportunity to work with Raven Windows both as an installer and as a customer using them in my own build, and both experiences have been outstanding. From an installation perspective, Raven Windows are exceptionally easy to work with. The process was smoother and more straightforward than installing North American-style windows. The innovative clip system eliminates the need for drilling holes into the frame or relying on a nailing flange, allowing everything to be done from inside. This design not only maintains the frame's integrity but also simplifies and quickens the installation process. As someone with extensive experience in installing windows and doors, I can confidently say Raven's European-style windows are the best I’ve worked with. As an end user, I’ve been equally impressed with their performance and quality. If you’re looking for high-quality windows that are easy to install and deliver exceptional results, I highly recommend Raven Windows!

We always prefer to work with Raven and confidently recommend them to our clients. A trusted partner for anyone seeking top-tier craftsmanship and professionalism! Debra Rigby Design

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?
