"Called them last week. Told them I had an emergency in that a window just cracked and was putting house up for sale.  The estimator who came told me it would be weeks before they could put me in the schedule but when I called that afternoon I was told we will do it as soon as we can.

I need all told 6 window panes replaced.  The cost was very fair and they came within a day.  The fellow who came (Brian) was very nice, left a clean room and did a nice job,

I went to put on some weatherstripping over a gap in the frame and saw one of the window panes was not quite affixed in a corner (slightly pulling away) I called and Brian came right back over and explained it took time for the putty to dry. I did nto know that (obviously ((*_*)) and felt a little silly calling him back but he was fine with it, apologized said probably should have explained that but he was glad I called since I had the concern,

I would use them again in, as they say, a New York minute."

"James and his crew arrived first thing in the morning and worked all day. They replaced 22 wood double hung windows with new Okna 600 Eco-Pro vinyl windows. The new windows look and work great. There was one minor problem with the horizontal sliding window located in the kitchen; on speaking with the owner Tom, they have ordered the required parts and will return to install them. Overall we are pleased with the quality, workmanship and value of the windows. They make the house look much better and are easier to operate than our old windows. We would use AJ window and Door Solutions again and would recommend them to others. Thanks Barb and Joe H."

"I liked that there was no nonsense. Their salesman was straightforward and the price was fair. We were also impressed with the installers. They installed all the windows in 1 day and they look great. I'm happy I chose them."

Windows FAQs, answered by experts

In short, it depends. After 20 years, the glass in your windows is less energy efficient, which can cause increased electricity bills. You might also see signs of water damage or natural wear and tear over the years. However, with proper maintenance, some window frames can last up to 50 years, so you may only need to replace the glass to save on energy. 

At the same time, window replacement is a major investment, so replacing the glass in rooms most impacted by outdoor temperatures is one way to avoid going all-in to replace your windows.

Most properly installed and maintained windows last between 15 and 20 years. Fiberglass windows last much longer than your average window. Since they don’t warp from temperature changes, rust, or rot, you might be able to hold onto fiberglass windows for up to 40 years. On the other hand, poorly maintained wood windows may only last for a few years.

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.

Yes, you can install a bay window in an existing house. You’ll need to have a structural engineer draw up plans to add the necessary support to your exterior load-bearing walls and a general contractor to make the changes to the framing around the new wall opening. This will cost an average of $3,000. After that work is done, a window installer can set the new bay window in place.

Garden windows can add value to your home and are an attractive feature for potential homebuyers. These windows add a custom look to your home and usable shelf space for homeowners with a green thumb. You’ll likely recoup your investment when it comes time to sell.
