About Us

About GT Exterior Design & Development LLC

GT Exterior Design & Development LLC was built on experience, hard work, and a genuine passion for helping people. Founded in August 2023, the business was created to offer homeowners a better, more personal experience when it comes to exterior construction and remodeling.

We are proud to be family- and community-oriented, and we believe that personal service still matters. When you work with us, you are not dealing with a large company where you get passed around, you are working with someone who takes pride in doing the job right.

A more personal way to serve homeowners

Owner Tomasz Wozny started this business because he enjoys meeting new people, helping others, and using his experience in the trades to make a real difference in the community. For him, this business is about more than construction, it is about building relationships, being accessible, and delivering work people can feel good about.

Our front bay window developed some bad water leaks over the past few years. Tom and his team replaced all of the flashing and added gutters to stop the leaks. They were on time and very professional. We were so happy we asked them to re-caulk all of our other windows and they even fixed our front storm door! Bring on the bad weather we are ready now! Highly recommend them, you will not be disappointed!!!
