About Blaze Window Systems

We are a small,  family-owned & operated St. Louis business since 2004. We are not a franchise with our headquarters in another state. We KNOW St. Louis homes! From historic Soulard to Chesterfield, we handle it all!

We will help you choose the best replacement window for your needs, with KNOWLEDGE, HONESTY, and INTEGRITY at prices our competitors can't beat due to our low overhead.

Customer satisfaction is always our top priority!  We will be there for you from start to finish and years later if you ever have issues with your windows.  

My name is Oliver Blase, the owner of Blaze Window Systems. I've been in the window business for 40 plus years. I was born and raised in St. Louis. In fact, I grew up in the Soulard neighborhood. 

Our family team consists of myself, my daughter Nancy, my son TJ along with my trusted installers that have been with us for over 20 years. 

We are able to offer affordable, high-quality name brand windows at prices our competitors can't beat due to our very low overhead.

Give us a call for a free estimate!  We will treat you like family. No high-pressure sales tactics. We are not commissioned based. 

We look forward to hearing from you!

No pushy salesman to try to upsell you to earn high commissions. We are highly knowledgeable about replacement windows and will only sell you what you want. We won't take up hours of your valuable time or offer you special pricing if you "buy today". Our prices don't need gimmicks. 

At Blaze Window Systems, we have a non-proprietary supply of windows from various manufacturers. We never pressure you into making a purchase – instead, we focus on helping you find the best products for your needs and budget.
