Say goodbye to drafts and hello to comfort with new energy-efficient windows. When it comes to keeping your family comfy and cozy, your home deserves the best. New windows also give your home an overnight facelift, and a decent curb appeal boost.

And in Canada, where the weather can be quite extreme, having excellent windows is crucial. Our windows stand up to harsh weather, even when all 4 seasons show up on the same day! Properly installed windows seal your home, shut out cold air during winter and keep you cool in the summer. This helps lower your energy bills and keeps you comfortable year-round.  

New windows work wonders for your home's efficiency, but they also transform the way your home looks. See the world through new windows — our team is here to help you through the process.

Frequently Asked Questions

What are the signs I need to replace my windows?

Plus icon - black

If you're experiencing any of the signs below, it's time to consider booking a window replacement consultation:

  • Drafts: Are whistling sounds or a breeze coming through the windows?
  • Higher energy bills: Your furnace and A/C units work overtime to make up for those drafty windows.
  • Single pane windows: These windows offer no insulation, soundproofing and lack energy efficiency. When replaced you will be sure to notice a sufficient drop on your energy bills.
  • Hard to operate: Opening and closing your windows should not be a daily struggle. Not being able to properly lock or securely shut windows can cause a home security risk.
  • Condensation: Condensation can happen for several reasons, but if it is constant and frost appears — it’s a window issue.  
  • Moisture between panes: There should be an air tight seal between your panes of glass. If a seal is broken than moisture can occur, and replacement should be considered.
  • Outside noise: Older windows do not provide much sound insulation, so if you can hear everything day and night, you might consider new windows that absorb the daily noises!
  • Decaying, damaged frames: Even the highest quality of frames can decay over time, and in some cases mould can develop. Any sign of mold means it's time for a new window!
  • Curb appeal: Modern, energy-efficient windows can also add valued curb appeal to your home!

Can I replace my own windows as a DIY project?

Plus icon - black

If you're handy and have experience replacing windows, it's a project you can take on as a DIY. However, many homeowners choose professional window replacement over DIY.  

For one, window replacement is a time-consuming project, especially if you don't have much experience. If delayed, this project can leave your home unsecured.  

Another good reason to hire a pro window installer is quality assurance. Improperly installed windows negatively affect the way your home looks — and won't provide the same performance. Pro window installers also come with a warranty, guaranteeing a quality install.

ENERGY STAR® certified windows can seriously cut down your energy use. Plus, they can save about three-quarters of a metric tonne of greenhouse gas emissions every year. To put it in simple terms, it's like planting 80 trees' worth of carbon offset.
