"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."

"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

Casement window types differ from standard windows in that they have a hinge on the side or the top of the window so that it can open inwards or outwards. If your casement windows open upward, they usually have a crank to operate them. Casement windows with side hinges typically operate like a door, opening and closing without a crank.

Bay windows are expensive mostly because their above-average size means higher material costs. Unlike bow windows, most bay windows also include casement windows on either side of a picture window, and the opening mechanisms for casement windows drive up costs. You’ll also pay higher labor costs to install a bay window, as you’ll often need multiple technicians to lift the window into place.

High winds can be harmful to casement windows and all types of windows. Because casement windows can swing outward, high winds could slam the window against the side of the house, bend the hinges, or even rip the window off of the hinges. If you hear some strong gusts outside, it’s best to pull the casement windows shut until it all blows over.

Storm windows provide several key benefits. They offer improved insulation and soundproofing, which adds comfort to your home by regulating internal temperatures and blocking external elements. Storm windows also help reduce energy costs by preventing cold or hot air from getting inside. Additionally, they can protect the primary glass in your windows against weather damage.

Windows with muntins are slightly more expensive because you’re paying for more material, but the cost shouldn't be that much higher since most muntins are fake on modern windows. You’re looking at a cost between $25 and $100 more per window for muntins, depending on the type. The only exception is if you want custom muntins to match your home style or meet your personal preference. Most manufacturers will charge more for these as they can’t mass-produce them. Windows with true muntins are rare, and they’re much more expensive upfront and over time if you ever need individual glass replacement.
