Customers say: True professional

"I contacted CWE to replace 8 windows and 1 patio door. Jeff came by and did the consultation. He was very friendly and professional. Communication 5/5 - Jeff was very responsive to questions and clearly communicated the work and timeline. Timeliness 5/5 - Both the consultation and installation started on time. The windows actually arrived sooner than expected. Quality 5/5 - The installation team laid down blankets before starting any work. They removed the old windows without damaging the surrounding wall. They installed the new windows and applied the cleanest caulk line I’ve ever seen. They cleaned up after themselves. The Anlin windows that were installed works perfectly and are beautiful."

"American Home Renewal did an excellent job. They were incredibly responsive and helpful, especially when dealing with the special circumstances and constraints of retrofitting windows within the guidelines of an HOA. Mark who ran my initial estimate and supported the project through the end of the contract creation and signing was always available to answer questions and willing to help out when I needed support with my HOA. The installation team did a wonderful job, they were prompt, professional, and courteous. And when I discovered several tears in one of the screens about a month after the project, AHR sent someone right out to fix it. I am extremely happy with my new windows - the house is much warmer and quieter now, and I've already recommended the company to several of my neighbors."

"Window measured, created, and installed in a reasonable time frame. Had to pick up broken glass (from old window) after. At first rain the window leaked from one of the screws in the inside top of the frame; I called Roxy and they sent someone out to caulk that screw. At the next rain the another screw leaked so I went ahead and caulked all the screws. Could be a flashing or other wall issue... Otherwise window has performed well over the last year."

"Great experience. Found AMG doors and windows online and they reached out and were able to clearly and professionally explain the step by step process of measuring the door ordering and the installation process. They were hassle free and was able to give me and over the phone quote for my new French doors. The install only took them 4 hours and they keep the space clean and were very professional."

"Excellent! They did such a great job and at an outstanding price. I have so many windows in my house and they came in way below any other competitor. It's been a few years but the windows still look and work great! As a matter of fact, my next door neighbor recently hired them to replace all of their windows based on the job they did at my house."

"Our family room needs a ton of work because it is an old house and we cannot afford to get it completely redone. The flooring in our family room needed to be replaced so we decided we would just do the one room for now and get new flooring throughout and paint too. We called Bayside Builders and they came up with a plan which included new flooring, paint, wallpaper and other items that should be done."
