Answers to Your

Common Questions


Can you make my window larger?

Yes, we can make your windows larger. However, first we have to make sure the structural load above the windows is supported properly. Depending on your needs, there may be higher installation costs because of this.

How fast can you install my window and doors?

Once you’ve placed your order, you can expect it’ll be 6-8 weeks until we can install your new windows and doors. If you need a tighter timeframe, please let our team know and we’ll do our best to work within your needs.

Can I get new windows or doors in the winter?

Yes! Our crews work to -15C and are able to quickly replace your windows. We’ll then finish the install by insulating around the new window and, if needed, come back on a warmer day to apply exterior caulking.

How do I properly care for my windows?

To avoid scratches and keep your windows looking great and performing well, it’s important to occasionally clean your windows. Use a mixture of dish soap and water, rinse it completely, and dry with a soft cloth.


Do you offer custom-sized doors?

Will I need to repaint my walls when I get a new door?

We take great care when we’re installing your new doors and take precautions to prevent damaging your walls. If you have any questions or concerns about your install, please give us a call or stop by our Kelowna showroom and we’d be happy to discuss our installs with you.

Will someone need to be home during the install?

Yes, we do require someone to let us into your home and answer questions. 


Do I have to register my warranty online?

Our team takes care of registering your warranty so that you can rest easy knowing you’re covered.

Is my warranty transferable to the next home owner?

Your warranty is generally transferable to the next homeowner for 10 years, but we recommend contacting us for specifics.
