Real reviews from homeowners who chose THT Windows for their replacement window projects.
"The estimator came out the next day after we called, measured everything, and explained all our options clearly — no pressure at all. Installation was fast and clean, and the new windows have completely changed the look of our house. Very happy we went with THT Windows."
"I got estimates from three companies and THT Windows was the most knowledgeable and professional by far. They took time to explain our window options and why the casement style was the best fit for my kitchen. The installation team was respectful and cleaned up after themselves completely."
"Our bay window in the living room was old and drafty for years. THT Windows replaced it with a beautiful new bay window and the result exceeded our expectations. The crew handled the full installation in about four hours. We noticed the difference in comfort immediately. Worth every penny."
"We replaced three large picture windows across the back of our house and the transformation was dramatic. THT Windows matched the grid pattern on all three so they look consistent, and the energy efficiency is noticeably better. Great communication from estimate to installation. Highly recommend."
"We had a sliding glass door and four windows replaced on the same visit — THT Windows made it seamless. The sliding patio door is buttery smooth and the windows look so much better than the originals. The team showed up on time, worked efficiently, and left the house spotless. Five stars without hesitation."
"I was nervous about replacing all 11 windows in my home but THT Windows made the process so easy. From the free estimate to the final installation, everything was handled professionally.
