"We are extremely happy with A1 Home Improvement. We hired them to install siding on our home. From start to finish, wonderful staff to work with. Joe, our salesperson, spent a lot of time with us and even provided a 3D image of what our house would look like once completed. Tawana and Lisa promptly answered any questions brought to them. The installation team, Jose' and his crew were wonderful and did an excellent job. The guys that installed the gutters also did a great job. Our overall experience was excellent. Our home is just beautiful!"

"Windows will take a few weeks to manufacture since they are being made for specific sizing. The windows are triple pane windows with argon gas in between each pane. We replaced 70-year-old windows, which were starting to rot. So glad that we replaced them. The windows are bit pricier than what you find in Home Depot, but quality is better."

"I hired C&S craftsmen and the are the best contractor I've ever had the pleasure of working with. They were on time, professional and diligent. They took extreme pride in their work. They made sure that we fully understood what the process was and how long it would take. I would recommend C&S craftsmen to anyone looking for reasonably priced quality work done by a professional crew."
