Frequently Asked Questions

Got Questions? We've Got Clear Answers.

How do I know it’s time to replace my windows or doors?

You may notice drafts, difficulty opening or closing, rising energy bills, or visible damage like rot or warping. If your windows or doors are over 15–20 years old, replacement can improve comfort, security, and efficiency.

Can I get both windows and doors installed in one visit?

Yes, many customers schedule both window and door installations together. It’s a convenient option that saves time and ensures your entire home gets a seamless upgrade.

Do you offer energy-efficient window and door options?

Absolutely. We work with high-performance, energy-efficient products designed for Ontario’s climate. These options help reduce heat loss, lower utility bills, and improve indoor comfort year-round.

How long does a typical installation or replacement take?

Most standard window or door installations are completed in just one day. Larger or custom projects may take slightly longer, but everything is planned to minimize disruption to your home.

What should I expect during the window or door installation process?

The team arrives on time, protects your space, removes old units, and installs the new ones precisely. Every opening is sealed properly, and cleanup is done before we leave. You’re left with a flawless finish and fully functioning product.
