New Build & Supply

If you're a homeowner who likes to get their hands dirty or a professional builder, we're here to help you order windows for your project, tailored to your exact specifications.

What Our Clients Say

  • "We have used Enertight Windows and Doors for over 20 years, and always with complete satisfaction. They have competitive prices with quality product. The staff is efficient and professional. They are a very pleasant company to work with."

    Betty Wilson from Nepean

  • "I replaced all windows and the front door in a home in the heritage designation area of Lowertown. Windows are excellent functionally, of course. But more important, the work was done while entirely preserving the interior trim (impossible to replace) and keeping the facade in character (great, minimalist flashing). Be prepared for sawdust. They clean up but cover beds, carpets and furniture."

    Stephen Brockwell

  • "I have had a lot of experience with Ener-Tight Windows both with the properties managed by my properties and our personal condominium investment properties, so I had no hesitation in using them for my principal residence. They gave me a written quote and an estimation of when when the window would be ready for installation. The final cost matched the estimation and I was advised in advance of the day and timing for the installation. They arrived at the appointed hour of 08:30 and by 10:30 they left having shown us the installed window and how it operated. they respected the contents of our home by using drop cloths to protect our floors and carpets. It was a completely painless operation from start to finish."

  • "The representative was very helpful, and delivery was earlier than we had expected. The crew that installed the door were very professional. We will reach out to EnerTight again with any other window or door replacement."
