"EcoView has been absolutely amazing to work with. They gave us an amazing price on the siding and all our windows and doors. We didn't feel pressured to sign a contract like we did with other companies. We were so lucky to work with Anthony, Rob, Steve, Diana and Carlos's crew. Not only did they do an amazing job on our siding but we happened to have another company at our house to give us an estimate on our doors and windows (we didn't know EcoView did doors and windows as well) and we were so lucky that Steve had stopped by to see how the job was coming along. EcoView ended up saving us $10k compared to the other company. Carlos's team did our siding and they did such a great job that we requested his team again for the windows and doors. Rob and Steve were very quick to respond when we would call or text with any questions or concerns. We loved our experience with EcoView so much that we recommended them to a friend within days of getting the work done!"

"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."

"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."

Customers say: True professional

"We hired Bill to attach a ramp to a doggie door. Knowing that we wanted the job done as soon as possible because our dog is blind, he offered to come on a Sunday morning. He had several suggestions on how to do the job and clearly was concerned about our needs. Bill and his co-worker, Travis did the job perfectly and at a reasonable price. They were polite and cleaned up, even using a blower on our driveway to remove sawdust. I highly recommend them and would hire them again."

Window Door Contractors FAQs, answered by experts

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.

Many windows carry warranties from the manufacturer or installer that may cover the cost of repairs for a fixed amount of time. When installing or replacing windows, ask about any applicable warranties, what kinds of damage and repair they may cover, and what the procedure is for making a warranty claim.

It is generally recommended to remove window screens for the winter, especially in climates with heavy snow, freezing rain, or frigid temperatures. Removing them helps prevent damage to the screen mesh and frames that can be caused by ice and moisture buildup between the screen and the window. Taking out the screens also allows more natural light and warmth into your home during shorter winter days and makes it easier to clean your windows thoroughly. In warmer climates where harsh weather is not a concern, the decision is more about personal preference; some homeowners prefer the clearer view, while others leave them in for convenience.

No, but removing window screens will achieve a deeper clean. If you aren’t sure how to remove your screens, you can still clean them while in your window. You can follow the same cleaning steps, but you may not be able to get into corners or struggle to clean the entire screen if the window is up high.

The best type of window screen for your home depends on your region and your family’s needs. While fiberglass window screens are a popular, affordable, and easy-to-find choice, you may be looking for different benefits, such as a more high-end look, increased strength, or extended durability. The best window screen meets the demands of your home and its residents while staying within your budget.
