"It went extremely well. They kept us up to speed on their arrival times. Eduardo and KC were courteous, professional, and did a great job on our windows. And, they came in at the lower end of the estimate. I will hire Smart Window Cleaning again."

"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."

"Adam clearly explained my choices, with prices, for my door screen repair work. His work was excellent and his prices were reasonable. He arrived on time, with a text message just prior to his arrival, as agreed."

"All went fine. First a door to door sales person , and we made an appointment with an estimator. A few days later she called to confirm a couple hours before the app.  She arrived on time and we came to an agreement  on the job and price.  Later someone  showed up and measured all the windows and ordered the custom built windows. About 10 days later they called and made an app. for installation,  the craftsmen arrived on time and did a wonderful job.  Jack J Bradbury

"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 FAQs, answered by experts

Mulled windows are often more expensive than standalone windows. However, this is mostly because mulled windows tend to be larger than standard windows, meaning they require more materials and labor to manufacture and install, both of which drive up the cost. If mulled windows take up the same square footage as separate windows, they should cost about the same unless you need to reinforce your exterior wall to support the larger wall opening.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

There are several ways to reduce noise coming through your windows. You can seal gaps around the window frames with acoustic caulk or fresh weatherstripping to reduce noise and air leaks. Installing sound-dampening curtains, thick blinds, or shades can also help deaden sound vibrations. For an additional interior barrier, consider installing an acrylic or plexiglass sheet inside the window, which stifles sound while still allowing for outdoor views. Another strategy is to add external barriers, like dense shrubbery or a sturdy fence, to block neighborhood noises. If these methods are not effective enough, it might be time to install new noise-canceling windows.
