"We are very happy with Premier Windows. The quality and installation work was efficient and professional. We ordered just before the covid19 lockdown began, and wondered how it would come together. Being older, we worried about letting a crew into our home, but decided it would be a go. The crew wore masks, worked quickly and were conscientious of distancing. The workmanship was excellent, the product is of great quality, and we found Pat Patel, the company rep, honest and informative. Pricing, while still expensive, at $5950, was approximately 1/3 less than other estimates. We would definitely hire again, and will highly recommend."

"From the initial contact through installation, this experience was wonderful. Price was ideal and the workmanship spot on. We even had them clean the window wells (YUCK) we live near farm land and have lots of bugs and critters..."

"They were very good. They'll even come back if something happens. One time I had a window that wouldn't close right. They came back and showed me. They really stand behind their work. The other thing was they even match up to the wood so I didn't have to have anything stained. They do good work. They were very good about coming on time. Two different times I've used them. We have a lot of windows in my house so we can't afford to do them all at one time. They're good and they have good quality. They stand behind their stuff."

Windows FAQs, answered by experts

Yes, egress windows are grandfathered. However, this comes with some specifications. If you are remodeling a basement or adding a sleeping area, you’ll need to update the egress windows to be up to proper code. But, if you’re leaving your home as is, you do not have to adhere to these requirements.

When specifying window sizes, manufacturers use a standard four-digit code system. The first two numbers represent window width, and the last two represent window height. For example, a window with a code of 2917 has dimensions of 2 feet, 9 inches wide by 1 foot, 7 inches high. Windows with even dimensions include zeros as placeholders. For example, a window that is 5 feet wide by 2 feet high would have a code of 5020.

The lifespan of smart windows or smart glass can range from 10 to 50 years, depending on the specific type, brand, and usage. When activated, smart glass is rated to last for about 100,000 hours. Since the windows are not typically on 24/7, this can translate to a lifespan of 20 years or more. Smart window film, a related product, generally has a shorter lifespan of around 10 years.

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.

Yes, replacing windows can boost your home’s resale value by improving its curb appeal, energy efficiency, and comfort. The return on investment (ROI) varies depending on the types of windows you install, but most homeowners see an ROI of around 60% to 70% of the cost of the window installation, according to the Remodeling 2024 Cost vs. Value Report.
