"Highly recommend Ecoview for anyone doing their windows. We had their team install two dozen windows in our home and they were in and out in a day and a half. My wife and I work from home and they were very respectful of our time, kind, and professional. Thank you!"

"The professional (Mitch) tackled a difficult job. These were heavy patio doors, installed over 25 years ago, with damaged and worn tracking. They are now sliding easily and more securely with a new, secure lock. He is now putting a new lock on our front door. He is reliable, efficient and extremely competent."

"I hired 5 Star Home Improvement to install 5 new Andersen windows and an exterior door. The price was reasonable. Freddie and his team worked diligently to make sure windows and the door are installed properly. They covered furniture and floors during installation and cleaned up after the job was done. Overall, Iâ m satisfied with the job."

"Extremely happy with the work done by these professionals. One of the lowest bids, theyâ ve been in business for a long time, they take pride in their work, high quality materials used and attention to detail. All they do is siding and windows, so they get the job done right and get job done quicker than a general contractor would as they specialize in this area of construction. Steve was onsite everyday, quickly responds to calls and texts and the men working for him are hard-working, respectful gentlemen. The siding came out absolutely beautiful. They even did a little extra with no added costs. They did a fantastic job cleaning up when they finished, they used magnets daily to keep nails off the driveway and out of my tires. You canâ t go wrong with All Island Windows and Siding. Highly recommended! Iâ ll recommend them to anyone I know in need of siding, doors and/or windows."

Window Door Contractors FAQs, answered by experts

Adding a window to a brick house costs $3,100 to $10,575. Because you’ll need to make changes to the structure of the home, the cost will include obtaining permits and hiring the best pros for this complex job. Larger windows will cost more to install, and the cost can vary based on the window frame material you choose.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.

Most window screens last for about 10 to 12 years, assuming they are made from quality materials and receive proper care. The lifespan of common materials like fiberglass and aluminum can vary based on weather exposure, as constant sun or harsh winters can accelerate wear and tear. Regular cleaning and basic maintenance can help extend their life. Signs that a screen needs to be replaced include rips, tears, brittle or sagging material, fading, or a bent frame. While small tears can often be repaired, larger areas of damage typically mean it's time to replace the entire screen.

Yes, if you have ventilated skylights, you can install insect screens on them. Insect screens for skylights cost $10 to $50 each, depending on their size and quality. Most pros highly recommend insect screens for ventilated skylights because they keep pests outside of your home while allowing fresh air inside.

Yes, professionals can enhance screen durability by using robust materials like stainless steel or fiberglass and employing advanced installation techniques. They provide reinforcement and repair services that extend the screens' lifespan while maintaining functionality and appearance.
