Window & Door Installers in Algoma District

Per-window pricing drops as quantity rises, so a whole-house quote is rarely the single-window price multiplied out. Be careful comparing quotes where one is retrofit and the other is full-frame. They are different jobs, and the cheaper one is not necessarily the worse deal, but you should know which you are buying.

Questions to ask before you hire

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?

Are your installers employees or subcontractors, and are they manufacturer-trained?

What is the lead time, and what happens to my deposit if it slips?
