"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."

"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."

"We were extremely pleased with the 20 new windows we just had installed by Pawel at Unicorp. The installation was very professional, they cleaned up each day and were very easy to have at the house. Brian Weil, the owner went above & beyond explaining the different types of windows, ultimately we wanted the look of the 1964 windows we were replacing with grilles on the inside & outside but just more efficient. We are very pleased with the end product. Both Brian and Pawel were very patient with me and the questions I had. I highly recommend calling Unicorp should you need new windows."

"I reached out to Paul to get a quote for new basement windows/door for my house. His company's estimate was stress free and used a local window manufacturer with an amazing reputation. Paul explained the different types of windows, the insulation and noise blocking qualities of each and provided guidance when I needed it. Once my selection of the windows was completed, I was provided an installation timeframe and signed the contract. The contract was clear and simple and I appreciated the explanations provided in it. When the windows arrived, Paul scheduled a day for the installers to come and replace the windows. They were careful to make sure it was on a day when it was not raining to keep the rain out of the house. As with all window and door installations, the installation quality matters as much as the windows. Pauls team of installers is a team he has been using for many years and they are absolutely excellent at what they do. The insulation and caulking as well as the functionality of the windows is perfect and I cannot recommend anyone more than Paul and his team at Innovative Home Improvements."

"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."

Window Door Contractors FAQs, answered by experts

A screened-in porch requires maintenance to keep the screens clean and in good shape, and you may have to do some screen repair or replacement from time to time. A screen porch isn’t an all-season porch, so the weather can get in, including wind and rain.

Window screens can take anywhere between 10 minutes and an hour to replace, depending on the complexity of the replacement and the accessibility of the window. Replacing the screen inside an existing frame normally takes longer than replacing an entire screen, frame and all, if you purchase a prefabricated screen already mounted on the frame.

While the benefits of garage door screens usually outweigh the downsides, there are some cons to installing one. First off, they can be quite expensive, especially if you’re having a professional install a retracting screen or a custom size screen. Second, they let fresh air and natural light in, but they also don’t provide the same privacy from people in the neighborhood that a solid door does. As you might guess, screens also won’t insulate your garage, so they’re often not usable in colder weather.

A vacuum with a hose attachment or a lint roller can easily remove dust from your window screen. Pressure washing window screens is another option, but you should make sure you have the appropriate nozzle and pressure setting to avoid doing extensive damage to your window.

Yes, a variety of screen materials cut out glare from the sun. Solar screen material can block up to 90% of the glare and heat from the sun, saving on cooling costs. It also offers privacy yet unlimited outward visibility. The cost depends on the size of the screen roll, but solar screens cost between $25 and $90 per roll.
