"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

Because bay windows are a combination of three windows, there are many options for how wide or tall they can be. That said, individual windows come in standard sizes, and you can use those as a guide for the width and height of your bay window.

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.

You should board up windows when you need to protect your home either from intruders after a window breaks or from severe weather before you experience damage. To maintain home security with a broken window, get your window boarded immediately. If there’s a hurricane, tropical storm, or tornado expected in your area, board your windows a day or two beforehand to avoid emergency service fees.

Yes, egress windows must meet local building codes for size and accessibility. Professional installers ensure compliance.

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.
