I used Duane to replace my old wood window with new aluminum ones which are great for keeping the heat in and cold air out.

Jenny Wilson owning older home

My windows leaked every time it rains and it rains a lot in the Lower Mainland. Duane knew exactly what to do and I can sleep comfortably again without worrying about water damaage.

Theresa Webb Renovating our house

Our new front door is wonderful and really reflects the style of the rest of our home. Thank you Duane.

 Interior condensation is often caused by high indoor humidity and large temperature differences. If fogging occurs between the panes of double-glazed windows, the seal has failed. 

Consider replacement if you notice drafts, condensation between panes, difficulty opening/closing, or if your windows are over 15–20 years old.

Repairing is an option for minor hardware issues. However, if frames are warped, rotted, or broken, a full replacement is usually necessary.

  • Installation can happen year-round unless there is extreme weather (heavy rain or sub-zero temperatures). Winter can be a great time to buy due to off-season discounts.
