"F and A did a fantastic job cleaning our windows and doors! The communication was great, they arrived on time and cleaned every glass surface, sills, and screens until they looked almost new. It was wonderful to walk into the house and see the sun and plants through sparkling clean windows. We will hire F and A to clean our windows every spring!"

"I am very pleased with my new windows. I used Home Genius Exteriors to do my roof, gutter protection, and now Windows. This is an absolute amazing company, my salesman brendan was very helpful, Devan the Project Manager helped make sure everything went smoothly. Walter and Mike also from production were very friendly and professional. And Shawn, the window installer was polite,knowlagable, and efficient. And even cleaned up on his way out. Next on the agenda is to get a new door taken care of. Highly recommend HGE"

"Simply put, you will NOT find a better, more honest, more helpful, more easy-to-work-with, reasonably priced contractor than John Lee and his crew at J & K Home Improvement & Restoration! We had a "complicated" set of circumstances when our home was damaged by a storm, last winter. The insurance company sent out an estimator to assess the damage and, after the company recommended J & K Home Improvement & Restoration, I was introduced to John Lee. I eventually learned that John also does estimates for a variety of insurance companies (because his company is so well regarded), and he patiently listened as I described the nuances associated with our house. During our initial consultation, he was able to clearly describe all of the steps that would be necessary and answer all of our questions. Long story short, not only was John able to address EVERY single concern and request that we had regarding the eventual repairs to the house (including roof, siding, and a window upgrade that would have cost much more if we had done it at a later time), but he spent plenty of extra time making sure that everything we had talked about was addressed to our 100% satisfaction! He was also able to persuade the insurance company to cover more complete repairs than was originally specified by the first adjuster! In addition, when we had an electrical "hiccup" associated with all the pounding on the walls, John quickly sent an expert electrician to locate and correct the problem. He absolutely could have passed those charges on to us because the failure wasn't due to any mistake on the part of his crew but, instead, he picked up the unanticipated expense himself. It was truly a pleasure to work with John! He made a difficult situation as easy to manage as possible, and we would strongly recommend J & K Home Improvement & Restoration to anyone who wants to hire a quality contractor that stands behind their work and well-earned reputation!"

Windows questions, answered by experts

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.

On average, bay windows are three times as expensive as a standard double-hung window, so up-front cost is a major drawback. They also let in more natural light than most other types of windows, which can be a positive thing, but it can also lead to more aggressive fading and UV damage to furniture and flooring. Larger windows allow for more heat transfer, so bay windows tend to be less energy-efficient due to their size. Finally, window treatments for bay windows can be more challenging to find, and they’re more expensive than those you’d place over standard-sized windows.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

When you need new windows depends on a variety of factors, including the age of your windows, the age of your home, and the climate you live in. If you’re dealing with budget constraints, you don’t need to replace all your windows simultaneously. 

When buying new windows, you should consider energy efficiency, safety, and aesthetics to choose the right window for you.

There are many high-quality window companies on the market, although Andersen, Pella, and Marvin continue to be the most popular nationwide. Some brands, like Sunrise and Soft-Lite, are popular regionally but may not be available in all parts of the United States. When comparing brands, look for features like increased energy efficiency, strong and durable materials, and long-lasting and all-encompassing warranties.
