"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."

"It went extremely well. Being female, many contractors gave me obscenely high quotes and didn't detail out prices (which I requested). Working with John at Best Windows was such a pleasure. He listened to my needs, was candid, honest, and detailed out pricing. Also, he provides the highest quality service for the best price. His team (pleasant & professional) Installed 14 windows. I expected minor issues. And John/team were quick to respond and fixed them immediately. I highly, highly recommend Best Windows."

"I highly recommend Windo-Well Cover Co. They were here when they said they would be, came prepared do the job even if it rained, and went above and beyond by cleaning out the window well before installing the cover. I am happy with the look of the cover, but am especially pleased with the strenth and durability of the cover. We will use them again to cover additional window wells."

Windows FAQs, answered by experts

Bifold windows work by using a track that allows panels to slide to the side and "stack" so they take up minimal space, leaving the largest opening. The sashes connect to each other with butt hinges or concealed hinges and to the window frame with the same type of hinges you’d find on a casement window. Some manual bifold windows also have casement stays or another piece of hardware to keep your windows in place when they’re open.

In most cases, it's worth it to install hurricane windows—especially if you live in an area prone to hurricanes and storms. Hurricane windows not only protect your windows from breaking but also protect the interior of your home from storm damage while also potentially reducing your homeowner's insurance premium. On top of that, hurricane windows have an ROI of 80% to 85%.

Because egress windows are meant for emergency exiting and entering, they need to be an accessible size. The smallest an egress window is allowed to be is 15 inches in width and height, with an opening of around 4 square feet.

Awning windows are just like hopper windows except that they open the opposite way. Instead of opening inward, awning windows open outward with a hinge at the top. This creates a mini-awning within your window frame, which is where the name comes from. Hopper windows, on the other hand, open inward with a hinge at the bottom.

Consider energy performance ratings, durability, aesthetics, and ease of maintenance when selecting windows for different environments.
