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."

"Great experience getting windows installed by American Home Renewal. First contact was 6 months ago. I slept on it for a few months and got some other quotes. Chris was friendly as a sales man, Gave me a competitive price and some pointers on fiberglass vs vinyl. I went with Vinyl. Alex was the installer and was very detailed in explaining the install process. He explained everything in detail to me and showed me tips on how to do a proper install. We did a mix of new construction and retrofit. we added window casings and he was very thorough and asked multiple questions on how I wanted the casings to look. only hiccup was one of the windows was ordered wrong. we couldn't determine where the mixup occurred but they immediately took full ownership and reordered me a new window to the specs I wanted. I would highly recommend."

"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."

"The tile in the shower was done well, but the tile on the floor was not. The tile was uneven, grout missing and they put in the wrong drain cover. So, they came back and fixed it. The etched window in the shower that was caulked had mold growing under it. They came back and re-caulked it. The thermostat for the floor was not installed on it's own dedicated circuit, so an electrician has to come and fixed it."

Windows FAQs, answered by experts

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.

Awning windows can have screens, but it depends on your manufacturer. If your awning window does have a screen, it will be on the interior side so it doesn’t get in the way when you crank the window open. Having the screen on the inner part of the window also makes it easier to clean from inside your home.

Upgrade to double-glazed glass or apply energy-efficient coatings to reduce heat loss and utility costs.

If your windows weren’t manufactured with a retaining clip to receive muntins and hold them in place, you should contact a window company near you to add them for you. A professional will bond the muntins directly to the glass to hold them in place, and they’ll make sure the edges line up nicely with your window frames. If your window does have retaining clips to hold muntins in place, you can just pop the muntins into the clips.

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.
