Real Google reviews from Charleston homeowners

Read what Charleston homeowners had to say about our window replacement and window installation, siding and gutter projects across the Lowcountry.

“Top Tier replaced 40 of our windows and some are over 18' high. They were excellent about, scheduling, impacting our family the least amount possible, keeping the house clean inside and outside, and the exterior finish work looks perfect. We couldn't be happier that we chose Top Tier. We would definitely hire them again. Feeling grateful!”

“Charlie with Top Tier Gutters and Windows just completed the replacement of windows at our home in Mount Pleasant. He is obviously very experienced and paid attention to details. The installation was seamless and the windows look fantastic.”

“I can see why they are voted number one in the low country. The estimate was free and the price was about what I wanted to spend. Shannon… explain[ed] how the process is to have them install the gutters for my house. 3 days later his team came out [and] install[ed] them. Worth every dime I spent — I no longer have water splashing on my house, … and they look wonderful on my house.”

“We decided to install replacement windows, and new Gutters in our home… Top Tier stood out from the rest by far. Barry was our salesman and he was very knowledgeable and never pushy. The installation team was professional, on time, and cleaned up after themselves. The windows are beautiful and the gutters look great. Highly recommend!”
