Canada Greener Homes Loan

Smart homeowners are taking advantage of the Canada Greener Homes Loan. This program allows you to lock in energy savings at today’s prices and start saving immediately on your utility bills, interest-free!

No reason to wait years while the prices of windows and doors, not to mention utilities, keep increasing.

Get loans of up to $40,000, ten years, interest-free.

This program can be even more beneficial than a cash rebate, as it allows you to potentially complete an entire project now.

Frequently Asked Questions

Beware of any window dealer offering huge discounts. Often they have inflated their prices to make an inferior window seem like a good deal. If possible try to obtain 2 or more quotes on the same brand of window, making it obvious which discounts are genuine.

Written references are ok, but they can’t show you the kind of workmanship that will be performed, nor can they guarantee that your installer is the same as the installer in a written reference. At Superior Home Improvements we do NOT subcontract work out, period. Continuity of the workmanship is assured because we don’t have staff turnover.  If possible, talk with a previous customer, that’s how we get most of our business, from referrals. If anyone ever has an issue, Karl, one of the owners, is always just a phone call or email away to help.

All our products are Energy Star Rated. Our windows are Energy Start Certified to meet the strictest rebate program requirements.

We welcome the chance to provide you with an in-home estimate and there is never any cost or obligation on your part. We are also happy to quote small jobs over the phone or via email, if need be.

Here are some sure signs that your old windows need to be replaced:

  • Difficult to open or close
  • Drafty, with air leaking through or around the window
  • Excessive condensation on the inside of the windowpanes
  • Windows rattle in the wind
  • Paint chipping or peeling
  • High utility bills
  • House is always -too hot in summer or too cold in winter
  • Water leaks or damp areas around or below the windows. Cracking of drywall or visible mould in the vicinity.

We no longer operate our own showroom as the amount of traffic didn’t justify the expense. All products can be viewed online, and our partners do have showrooms available to the public.
