Signs It's Time to Replace Your Windows or Doors
Newfoundland's wind, salt air, and extreme temperatures are hard on windows and doors. If you're noticing any of the following, it may be time for an upgrade:
- Drafts or cold air coming in around the window or door frames
- Rising heating bills
- Condensation or frost forming between glass panes
- Windows that are difficult to open, close, or lock
- Visible rot, warping, or seal failure around frames
- Noise from outside that seems louder than it used to be
- Outdated single-pane windows that don't meet modern energy standards

How long does window installation take?
Most window replacements can be completed in a single day. The exact time depends on the number of windows and accessibility, but our team works efficiently to minimize disruption to your home.

Yes — absolutely. Estimates are always free, and there is no such thing as a silly question. Contact us today, and we'll assess your needs and provide an honest, no-obligation quote.
Can you repair my existing vinyl windows instead of replacing them?
In many cases, yes. We service and source parts for virtually any brand of vinyl window on the market. If repair is the right option for your situation, we'll tell you honestly rather than push you toward a full replacement.
What is the best type of window for Newfoundland's climate?
We recommend Kohltech vinyl windows for most NL homes. They are Canadian-engineered for extreme weather, highly energy efficient, and require no maintenance like painting or staining. Their sealed thermal units are designed to handle our province's temperature swings and coastal salt air.
