Frequently Asked Questions

Is there a fee for consulting with an Isothermic advisor?

Absolutely not. You can meet with our team for free, either online or in person at our stores.

How do I prepare for my consultation?

First of all, you don’t need to know all the window and door lingo—that’s why we’re here. The easiest thing to bring with you is pictures of your current windows so that we can get an idea of what you have. Tell us which room each window is located in so that we can steer you to the right product. Tell us what year the house was built so we can get an idea of its wall construction. Finally, if you give us approximate measurements for each door and window that you want to replace, it would help us create a quote. Show us photos of what you like so we can get a sense of your favourite design and styles.

How long does it generally take for my order to be ready?

Can I have my windows and doors installed in winter?

Yes, absolutely. Our teams of certified installers are trained to do so. How? We remove and replace one window at a time, we create plastic barriers that we move as work progresses, and we keep doors to indoor rooms closed.

Can I buy Isothermic windows and doors without using your installation service?

What is an Isothermic Certified Installer?

Our Isothermic Certified Installers have completed the latest training on the A-440 national standard, as well as mandatory training on our products and our high expectations. They are required to participate in continuing training, score 100% in our training program, and submit to surprise inspections. Our certified installers are more than just skilled—they are passionate about doors and windows and will install your new Isothermic doors and windows with great care.

What do I need to do the day before the team of certified installers arrives?

Since installation sometimes starts early in the morning, here’s what to do the day before we come to your home:

Make room so our teams can move freely indoors and out.
Remove blinds and curtains.
Move fragile or valuable items out of the workspace so installers don’t damage them while working.

What should I do on installation day?

How do I prepare for winter?
