You’ll have peace of mind for years to come.

Choose Your Colour

Vinyl windows are available in standard white or beige fully extruded colours, this means that the colour is throughout not just painted on.

An optional Dark Oak laminate is available on the interior for added appeal on our casement and awning windows.

During this past summer we have purchased a new storm door, patio screen and replaced an existing window. I would like to personally congratulate DuoTemp’s office staff and trades people for the outstanding courtesy and service they have provided us. This type of courtesy and service is a rarity, we certainly would not hesitate to recommend DuoTemp based on this experience.

We recently had our basement windows installed by your company… This was the second job we had done with your company and we can honestly say that on both occasions your receptionist Marlene, your salesman Gord Howard and your installer Frank Minaker were very courteous, helpful and efficient. We really appreciate the extra few minutes Mr Minaker took to reattach our alarm sensor to the new basement window.

This letter is in regards to recent work that was completed in my home. Brady who was the gentleman that installed my windows did a superb job with the old out of square frames. Upon returning home from work that day I fully expected to have to clean the carpets in the rooms where the windows were replaced but much to my surprise everything was spotless. The free piece of fascia was also a nice touch.
