Our Promise

Our Promise

My name is John Wrzesinski, President of Best Windows Inc.

I have installed over 80,000 windows around the Chicago area since 1998, and people just like you have decided to trust me. We are proud to say we work out of my home which gives us a lower overhead; and the savings are passed on to you! It’s just common sense. Did you go to a showroom? No, so why pay for one or put up with some phony high pressure three hour, “Tonight Only” price with a heat lamp dog and pony show sales pitch that just insults your intelligence? You should ask, “what is the NFRC U-rating.” It shouldn’t be any higher than 0.27 to be Energy Star Rated in Northern Illinois.

Best Windows is a proud member of the Better Business Bureau. As of February 2007 to present, we have maintained an A+ rating with the BBB. Our company has excellent reviews across the web on Google, Yelp, Angie’s List, and the BBB

When Best Windows gives you an estimate, our promise to you is that:

Best Windows will provide and expertly install your windows at the guaranteed most affordable value you will find in all of Chicagoland. Our installers have over fifteen years of experience. We are licensed, fully insured and bonded. We will provide you with local references you can trust.

Best Windows will never ask for your spouse to be present! We will never use high pressure tactics like “today only” pricing and long drawn out sales pitches. We will never quote a very high price at the beginning and then lower it drastically if you tell us you need to think about it. Best Windows will get to the point fast because we know your time is very valuable and we respect the privilege of being allowed into your home. Our average time for a quote is only 45 MINUTES!

Best Windows will always be ready for your business. We have had the same phone number for over 20 years.

Best Windows truly counts on referrals and will pay you a minimum of $100 for every referral that purchases at least five windows and larger referrals fees for larger jobs. They will thank you for sending them to Best Windows and saving them time, money and aggravation.

We at Best Windows stand by this promise. Let us show you what it’s like to do business with the Best!
