Our Mission: Value for Generations

Our goal from the very start of the company has been to offer consumers the best value for their money. Many times the children of previous customers call to have us install our windows or doors in their first homes after witnessing the value their parents received from our company. We are in the business for the long run, intent on bringing value to generation after generation.

Local People, Local Expertise

Much of our success is due to the fact that we’re from right here. We understand Wisconsin weather and Wisconsin folks. We all grew up around here and our staff and their families are part of the community. We treat every job like we were doing the work for neighbors because we are doing the work for neighbors!

By the way, we do all the work ourselves. We do not use subcontractors or outside labor for our installations. Our installation teams are fully trained, certified and experienced. And because we use only our own people we have full control over scheduling and quality.

We Guarantee EVERYTHING!

Some window companies offer a manufacturer warranty on window parts. AHT Windows is one of the few replacement window companies in Wisconsin to offer a full 50-year non-prorated warranty on our windows. The warranty is not pro-rated and is fully transferable if you sell your home. No worries with us!

Licensed, Certified and Insured for Your Protection

AHT Windows is a licensed contractor in the State of Wisconsin, and we carry full liability and workers’ compensation insurance coverage for every job. Why is that important? If you choose a contractor who is not insured and an accident occurs on the job site, you may be held liable! AHT Windows makes sure you are protected.

In addition we are fully certified by the manufacturers of the windows and doors that we install. Because we are certified all manufacturer warranties are valid and in full effect. Installation by a non-certified contractor may mean that the warranty is invalid.

Aw, We’ve Won Some Awards

People other than our customers think we are OK, too. AHT Windows has been named one of Qualified Remodeler magazine’s “Top 500” home improvement companies every year since 1998 including #105 on the 2009 Qualified Remodeler Exterior 200 and #137 in 2008. Our company has also been ranked #104 on Remodeling magazine’s “Top 550” for 2009 and one of Replacement Contractor magazine’s “Replacement 100” for the past two years.

We must be doing something right.
