Curb Appeal

Want to see clearly and increase your home's curb appeal? You will be thrilled by the appearance and function of these windows. My home is now warmer in the winter and cooler in the summer months. The installation was quick and clean. The new windows look amazing! The employees were professional, well organized, and recommended choices that worked well for my home's exterior.

Outstanding work all around!


My experience with the company from the begininng was exceptional. There knowledge from the start to finish is unusual in the business world today. I highly recommend them for their professionalism and the quality of materials that they use.

Awesome Job

Guaranteed supplied us with an excellent product and outstanding workmanship. We are delighted by the appearance of our lake cabin with new siding,soffit and trim. It was a quick but professional makeover. The crew worked 8 or more hours every day and cleaned up the yard every evening before leaving. I highly recommend Guaranteed if your looking for a quality product and an exceptional installation.

Great Job!

Excellent, Fast Professional Service

I had them install rain gutters on my house. From the sales man to the installer everything was smooth and fast. The salesman was not pushy and the installer was very professional.

They painted my house and did a great job from start to finish. They were on time and were super professional. I was nervous and they were patient. The clean up was great. You couldn't tell they were there. Thanks

Personal, fast service


Everything from start to finish was great. Salesman was friendly, informative and not pushy. Windows were put in quickly and with great care. The team did an excellent job cleaning up, going so far as to take the yard and touch up paint. The windows look fantastic and we couldn’t be happier.

Excellent Job!

James, Brian, and Randy did an excellent job siding our home. It absolutely looks 100% better than before! As they began taking our old siding off, they realized that our windows were installed incorrectly. Thankfully, they were able to redo them beautifully. The accent work around our windows and doors looks really wonderful and we appreciate all of their hard work. A plus is the way they clean up around the house every day. Thanks also to Corey for his input into this project and his knowledge of the Prodigy insulated siding. This has been a good experience all around!

Very impressed with the installation time

Kris S.

I was very impressed with the installation time. They came out for measurements, gave an estimate and out a few days later to install the guttering. It looks beautiful! Corey and Austin are wonderful to work with also...
