Elliott Duda

We had all our windows replaced with Marvin windows just over a year ago. We were extremely happy with the quality of service and product and still are today. Dave and Jake were great to work with and took a lot of time helping us choose the right product for our home. They also took great care while installing all our windows to ensure our home was left in the same or better shape as when they started the project. We highly recommend Lakeshore Windows to anyone looking to install Marvin products in their home.

Mauricio Rodriguez

Very friendly but I consider it expensive

Loris Macor

Dave was excellent to deal with. Took time to explore options. Delivered on time and when one issue arose he was there within a day or two. Pleasure to work with and if I had to do all over again I would deal with Lakeshore again.

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?
