| Material | Relative cost | Why choose it | Best for |

| Vinyl | $ | Most affordable, low maintenance, great efficiency | Most KW homes |
| Fiberglass | $$ | Extra strength, excellent efficiency, slim frames | Large or premium windows |
| Wood | $$$ | Classic look, needs upkeep | Heritage & character homes |
What affects your price
- Number of windows. More windows means a lower per-unit price, but a higher total. Full-home projects (10–12 windows) run $8,000–$18,000.
- Size & style. A large casement costs more than a small slider. Bay and bow windows are the priciest because they're custom-built.
- Material. Vinyl is most affordable; fiberglass and wood cost more (see vinyl vs fiberglass).
- Double vs triple pane. Triple-pane glass adds cost but improves efficiency and noise reduction — see triple vs double pane.
- Custom shapes & colours. Arched, bay, bow, or specialty colours add to the price.
- Old-frame condition. If we find rot or water damage during removal, repairs can add to the quote — we always flag this before doing the work.

Window replacement cost: FAQ
Is window replacement worth it in Kitchener?
For most Kitchener homeowners, yes. New energy-efficient windows cut drafts and lower heating and cooling bills, add resale value, and come with a warranty. If your windows are 20+ years old, fogging between panes, or hard to open, replacement usually pays off in comfort and energy savings.
Should I choose vinyl or fiberglass windows in Ontario?
Vinyl is the most popular and affordable choice and performs very well in the Ontario climate. Fiberglass costs more but is stronger, allows slimmer frames, and handles temperature swings with less expansion. See our vinyl vs fiberglass comparison to decide.
How long do replacement windows last?
Quality replacement windows last 20 to 30 years. Vinyl and fiberglass frames typically outlast the sealed glass units, which may need attention sooner if the seal fails. A written warranty protects you if anything goes wrong early.
How long does a window installation take?
Most Kitchener window replacement projects are completed in one to two days. A few windows can be finished in a single day, while a full-home replacement of 10–12 windows usually takes two days.
