How Do I know it is Time to Replace My Windows and Doors?

Over our 25 years in operation, we’ve seen a lot! We know that it can be difficult to pinpoint exactly when it’s time to replace your windows and doors, so here is a starting point that may help.


Windows and doors do not last forever, and age is the biggest indicator that the time as come to replace them. Depending on how much time has passed and whether or not they were installed properly, it may be time to look into replacements – we can help.

Operating Issues

Have you noticed that it has become increasingly difficult to operate your windows or doors? If opening and closing them has become more than a simple task, it may be time for a replacement.


Any time you feel drafts coming in around your windows and doors this is a sure sign that they are beginning to fail. It’s time to address the issue and ensure your windows and doors are functioning as they should.

Visible Damage

If you notice any visible damage such as chipping, deterioration, or stains around your windows and doors – don’t ignore these.

Energy Bills

Have you noticed a steady, unexplained increase in your energy bills? As windows and doors age, they lose the ability to properly insulate your home, which forces your air conditioning and heating systems to work overtime. New windows and doors provide improved energy, and thermal efficiency.

If you notice any of the above or are unsure, it may be time to contact a trusted Georgina contractor! We offer free, no-obligation inspections to help evaluate your specific situation in order to build a customized solution for your home.

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."
