(Based on 932 reviews)

Reviews often praise the value for money, with multiple mentions of pricing that compared favorably to other quotes. Homeowners cite quick, coordinated installations and crews who clean up thoroughly. Communication from sales to scheduling and installers is described as clear and professional. A smaller number of reviews mention follow-up delays on repair or service visits.

They upgraded 29 very large windows on my house and some even custom.
They had 11 guys here and got the entire job done in just A FEW HOURS!
Lifetime warranty on windows and caulk I don’t know how you would beat this. Anderson windows quoted me 250% more then window world when it’s the same glass just different casing. We’ll I enjoy my new windows and they are beautiful and whenever something needs fixed they are on it and my home is not an easy one out in the middle of no where down 8 miles of county road.

So I have to leave a damn good review a lot of people bash window world mostly competitors because they just can’t keep up with the pros! Don’t spend more else where these are insulated windows with tint heat does not go through them they are very good quality.
Everyone I worked with there was super nice and well kept. I honestly can’t think of anything negative to even say I even secured a 0% interest loan on the darn things for 3 years almost.

Excellent company to work with. Very reasonably priced. Great quality and installation. The installers cleaned up beautifully when they were done. I couldn't be happier with the results!!! Before and after photos are attached.

Scott Dickman on Window World of St. Louis

Had a new front door built and installed. The entire experience was great., from the initial visit for measurements and picking out details to Ben coming out and installing the door on one of the coldest days right after the big snow. 100% recommend using Window World. We will be back!

I had them on install new siding after a hail storm. Now I have siding falling off and have been trying for almost 4 months to get someone out to fix it.

Gregory Strautmann on Window World of St. Louis

From the sales person to the installation crew, every person I dealt with was friendly, knowledgeable, professional and treated my house like their own! They said it would be 6-12 weeks from the day of order but was only 2. They worked until 9:30 PM to ensure it was done 1 day and done right. The end result was beautiful and I no longer have a draft from the windows. Not to mention the cost was the best of the multiple quotes I received. If I need new windows again I will be calling Window World!
