Frequently Asked Questions
How is it possible for a window contractor to offer a 40% discount on my window order?
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.
Each company assures us that they do quality work. How do I know the job will be done right?
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.
Are your products Energy Star Rated?
All our products are Energy Star Rated. Our windows are Energy Start Certified to meet the strictest rebate program requirements.
Do you charge a fee for an in-home estimate?
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.
How can I tell if I need new windows?
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.
Do you have a showroom?
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.
I cant say enough good things about Karl and Jay! They came recommended and they did not let me down. They know the products, understood my needs and delivered excellent service at my expedited time frames. A pleasure to deal with!!
