"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."

"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

"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

In addition to window well covers or bars, you can take a few more steps to boost basement window security. Try motion-activated lighting; it scares off potential intruders by lighting up when someone gets too close. Strengthening your window glass with impact-resistant security film can also deter forced entry. A dependable home security system with window sensors and cameras offers real-time monitoring and alerts for added protection. Lastly, fostering good relationships with neighbors can establish a supportive community watch network, enhancing your home's safety.

Sometimes, you can buy windows directly from the manufacturer, and it may be cheaper than buying through a third party or wholesaler. Manufacturers may also offer more options, including custom shapes and features, or better warranties if you purchase through them directly. 

However, some companies limit the ability to buy from them, especially if you need standard pre-fabricated sizes, so don’t expect this service from every manufacturer.

A common way to modernize arched windows is to install interior window treatments that allow light through the curved portion up to and let you cover the bottom portion for privacy. You can also install plantation shutters to make an arched window look more modern. From the exterior, arched windows can appear outdated if they’re coupled with ornate trim, so toning down the decor can make your window look more natural with a modern design.

Whether or not you need permission to change the windows in your house depends on your local laws. If you’re enlarging an opening or installing a new window and need to make structural changes to the house, you’ll need a permit. In most locations, you won’t need permission if you’re just replacing a window with another window of the same size. The window installation company you work with will be able to help you navigate any planning permits you may need.

Yes. Vinyl windows have a PVC frame that wraps around a glass panel that is usually made up of two thinner glass panels separated by an insulating, noise-absorbing airspace. Some vinyl windows are triple-glazed, with three insulating air panels within them. This glass helps keep your interior quiet from outside noise while its insulating qualities help your space stay cool in the summer and warm in the winter.
