★★★★★ 5/5

"I would rate them ‘A’s on everything. They were great. I would recommend them to family and friends. That actually was our second time using them."

"This past Winter was really unusual for us – too cold! Thanks to our triple-pane windows from Ameritech we have saved about 50% on our energy bill."

"The siding installation was well organized by the project manager and job site manager. The installers were professional and efficient! The siding looks amazing. I truly got a new house at the same address. I’m so happy."

"We had them out a couple of years ago and they replaced most of our upstairs windows. They did a wonderful job demoing the quality and value of their triple pane windows and gave us a good price."

"The technician who came to see us was punctual, knowledgeable and courteous and did a fine job of explaining and selling his product. Ameritech has always been very good about follow-up on our windows, even sending someone out to reacquaint me with the tilt-in cleaning or replacing the balance systems. We will most certainly use them again in the future."

O’Sullivans’s Brookland Neighborhood Window and Door Makeover

The O’Sullivans came to Ameritech back in 2014 to replace a portion of their windows homes. Now, ready replace the remaining windows and doors, they knew they could trust Ameritech to do the job right again. The goal was to eliminate drafts and lower utility bills, something Ameritech could do, bringing in new windows to match the first phase and replace the old, ill-fitting doors that were letting out their climate control.

Our clients choose our windows for the structural integrity of the frame and our super low U-value (sometimes referred to as heat transfer coefficients or thermal transmittances), to get that desirable high energy efficiency. The O’Sullivan’s were ready to make the switch across the 30 windows and 4 doors of their home. The results speak for themselves! “The installation was really well done by Danny and his crew. He explained the windows and doors when we had questions and was efficient, courteous and professional. The windows and doors have excellent craftsmanship and quick installation.”

AMERITECH ADVANTAGE: We are fully committed to earning your satisfaction with our work. You can look forward to our remodelers listening to the details of your project, helping you select the perfect new windows or doors for your needs and budget, and complete a flawless installation.
