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."

Windows questions, answered by experts

You will need about half of a caulking cartridge to caulk one window. The average home has eight to 10 windows, so you would need about 4 or 5 cartridges to caulk every window in an average-sized house. However, you may not need to caulk all the windows at once. If just one window has a pesky draft, you may only need half of a cartridge to fill in the gaps.

Mulled windows are no less efficient than individual windows, provided the wall opening is the same size. Larger wall openings filled with glass will always reduce overall energy efficiency, as glass transmits heat more readily than a solid wall. If the windows that are mulled together have the same square footage as individual windows, you might actually see a small decrease in your electric bills, as mulled windows let in more natural light that can reduce interior lighting costs.

According to the U.S. Department of Energy, low-E windows can reduce energy loss by 30% to 50%. But the actual effect of low-E windows in your home will depend on many factors, like climate, number of windows, window treatments, and more. In terms of aesthetics, you may or may not notice a difference in how your windows look or how much natural light shines through. But overall, low-E windows look very similar to traditional windows.

Whether you need a permit to install a bay window depends on the project's scope. Replacing an existing bay window typically does not require a permit. However, if you are adding a new bay window, requirements can vary. Adding a new bay window to the front of your house usually requires a building permit, while adding one to the side or back of your house often does not. It's always best to check with your local municipality to confirm the specific requirements in your area. Additionally, if you live in a historic district, you should consult your neighborhood association to ensure your project complies with their construction guidelines. If you're unsure about the process, a professional can provide guidance.

Having a professional caulk your windows will cost you around $50 to $70 per window (or $1.25 to $4 per linear foot), including labor. However, caulking is one of the easiest DIYs there is, and you’ll save a lot of money by getting the supplies and doing it yourself. You’ll only pay $0.05 to $0.20 per linear foot if you DIY this one. Finally, different types of caulk don’t vary too much in price, with most tubes costing no more than $15 apiece (but typically only $3 to $10) at the most.
