I scheduled to have someone come give me an estimate for all new windows in our 1950s home with not so great Remodeling work by previous owners. Alex Li promptly met with us & his crew throughout the entire process. They were always on time to work, left our home clean of debris & spectacular new JeldWin windows. Helped me with getting Financing as well...Just all around a great experience & highly recommend!

I recently hired Hamilton Exteriors to replace my siding and windows, and they did a fantastic job. Their team was punctual, polite, and paid close attention to detail. The siding looks seamless, and the new windows have made a noticeable difference in both appearance and energy efficiency. Communication was always clear, and they finished on time and within budget. I’m very happy with their work and would definitely recommend them.

From the very first consultation, we knew we'd made the right choice. The team was knowledgeable and genuinely listened to our concerns about energy efficiency and design. We've already noticed a drop in our energy bills.
