"From the first meeting to obtain a quote until the team left, every step of the process was professional. Paul came out personally to show us a sample window and provide us a quote on windows and make recommendations to replace our patio and storm door. Paul patiently answered all of questions & communicated with us up thru the installation. The team of installers were quick and professional, replacing 11 windows, a custom patio door, and storm door within a day. They cleaned up every piece of packaging, metal, etc and demonstrated how to use the new windows. I would recommend Innovative Home Improvements without reservation."

"At first I was extremely apprehensive about buying all new windows for my home from one vendor all at once. Because, I was completely burned in the past from a previous contractor and they installed a few of my windows about 3 years ago and didn’t complete the job, it was a horrible experience and left a very negative feeling regarding purchasing windows from anyone in the future with the fear of being taken advantage of again. However, after analyzing and getting great descriptions of the windows and the installation process, I found it worth taking the chance and in my best interest to have ARHT Home Solutions do the work for me. His workforce was very professional and I was very satisfied with my new windows. I have decided also to use ARHT to install a new front door and storm door after the completion of the new windows that were installed. They showed up on time and was very patient with me, the work ethic was great through the entire process and am completely satisfied."

"Excellent work. The person who assisted us was gruff and no-nonsense, but professional. He asked that we send a photo of the window, which we did. He then came out and measured the window. He came back a couple of days later, and completed the work. The window looks fantastic, and we are very pleased with his work."

"If you need a door repaired, hire Dexter. He was absolutely professional from start to finish, incredibly humble, and his pricing was more than fair. He diagnosed the issue quickly and fixed it right the first time without trying to upsell me on anything unnecessary. Honest, high-quality work is hard to come by—I will definitely be calling him again if I need anything else."

"Supply chain crisis or not, we eventually got our beautiful window replaced and are so thankful to have it installed before the end of the year and the coldest months. Once our window found its way to Maryland, Horace and team got it to our house and installed within days during a holiday week."

"We purchased 37 replacement windows. Paul, the owner, was very personable and informative. No pressure was ever applied to purchase. On installation day, the workers showed on time, were polite, and were very efficient. They replaced all 37 windows in 1 day working until dark and returned the next day to finish the flashing around 10 windows. Paul showed midday on install day to see how things were going. We have hired IHI to replace a door and fix some flashing on other areas of our house. I highly recommend IHI."

Window Door Contractors FAQs, answered by experts

The screen on many screen doors is held in place by screen spline. Screen spline is typically a thin vinyl tubing that fits into the groove of the door’s frame and holds the screen in place. To install the spline on a screen door, you’ll need a spline roller—a tool that presses the spline and screen into the door’s narrow groove. Note that old spline can crack and break, so replacing your screens is a good time to replace the spline, too.

If your door has interchangeable inserts, you’ll likely want to swap the glass out for a screen during the summer months. The process to do so will vary by door, but you’ll follow these general steps: First, use a flathead screwdriver to pop out the retainer strips—the plastic strips running down both long (and sometimes all four) sides of the door. Then gently pull them out by hand. Carefully remove the glass insert from the door and replace it with the screen. Finally, push the plastic retainer strips back into place, working from top to bottom.

Yes, you can absolutely put a screen on a casement window, and most casement windows come with screens. Unlike with a double-hung, single-hung, or sliding window, the screen in a casement window sits on the inside of the window so that the sash can freely open outward. Screens are especially important for casement windows because the large window opening the window provides leaves your home more open to bugs and outside debris than most other types of operable windows.

Window seals don’t last forever, so they’ll inevitably fail for one reason or another. One of the most common reasons is the expansion and contraction of the glass. When the glass gets warm from sunlight, it expands and adds pressure to the seal; at night, as the glass cools, it contracts. This process, day in and day out, can eventually cause the seal to fail. Other common sources of failure include the house settling over time, chemicals that damage the seal when repainting windows, and incorrect window installation.

Window screens are available in several standard sizes. Common dimensions include 24 to 36 inches wide by 36 to 48 inches tall, as well as sizes like 18 by 14 inches and 20 by 20 inches. These often correspond to standard window sizes, such as 2 feet wide by 3 feet tall or 4 feet wide by 6 feet tall. Screens are also sold in replacement rolls to accommodate various dimensions. It is always best to measure your windows for accuracy before a repair or replacement. If your windows are a non-standard size, you will likely need to order custom screens, which can increase the cost. However, a screen does not necessarily have to fit the entire window, so you may be able to use a standard-size screen even if your window is slightly larger.
