Signs It’s Time to Replace Your Windows and Doors

Visible Damage and Mold

Visible damage seen with the eye is a key sign that it may be time to replace your windows and doors. If you notice any mold, discoloration, chipping, peeling, water damage or staining – it’s time to call in the professionals.

Decreased Energy Efficiency

Aged, damaged, and patched-up windows and doors lose a great deal of their original energy efficiency, compromising their ability to keep the home’s temperature regulated. This causes your heating and AC systems to work overtime, and your energy bills to skyrocket.

If you’re noticing your energy bills steadily increasing with no obvious cause, new windows and doors could be the help you need to improve your home’s energy efficiency, and decrease your monthly bills.

Drafts and Air Infiltration

This is another sign of your windows and doors becoming decreasingly energy efficient. If you’re feeling air coming in from around the edges and corners of your windows and doors, it may be time to get them checked out.

Our products come with air sealing technology which provides unmatched air infiltration protection to help eliminate drafts.

Operating Difficulty & Noise

It should not be difficult to open and close your windows and doors. If you are noticing that you are having an increasingly difficult time getting your windows to function and operate as they once did, it’s time to address the issue.

If you are hearing noises from the outside when your windows and doors are closed, chances are that they are not providing enough insulation and operating as they should be.

Cleaning Issues

Older, dated windows may be difficult to clean and make maintenance a hassle. Our glass uses a solar shield and anti-dirt coating to help keep your windows and doors spotless. This coating works to prevent dirt and rain from sticking to the glass, which helps make maintenance simple.

Professional Job and Cleanup

"Well our job is all finished. I want to thank everyone for such a professional job and cleanup. Adam, Justin and Paul were amazing and finished the eavestroughing and window installation without a hitch. Thanks to Adam for pointing out that the colour we had chosen was not the best match. He ordered the better choice and it was here on the job before they actually needed it. Thank you for not letting me put up the WRONG colour Adam."
