"Super fantastically well. Patsy Cicala and his crew were excellent. The windows were custom and had a trapezoid shape and they installed them perfectly from beginning to end. They weren't replacing windows but instead creating new ones and had to cut through my wall. It took about 2 days since they worked all day long for both days. The windows look terrific and my home was cleaned up from the minor mess. Patsy and crew were wonderful to deal with. The price was incredibly fair. I would hire Patsy again without question. Plus, he is fun to be around!"

"The Window People did an excellent job replacing an exterior door in my home. The contractor was very polite and capable and the door looks great and he cleaned up the area nicely when the job was done. I knocked one star off of my 'customer service' rating for the following reasons: First, he asked me if I had any caulk he could use (which I did, and which I offered him, but I think this should have been HIS responsibility, since it's something that a contractor should expect to bring with him to do the job, not something that you need to rely on the customer to supply (unlike the actual door, for example). Secondly, he asked if I had a caulk gun that he could use (which I did, but again, shouldn't the contractor be expected to bring caulk and a caulk gun to a job site where he knows he will need it?). And thirdly, he asked if I had a hacksaw that he could use to cut the molding (which I did, and which which I offered to him, but again . . . .). In any case, I am delighted with the work that was done."

Window Door Contractors FAQs, answered by experts

Installing a basement window generally takes a few hours, assuming there are no structural issues you need to resolve first. If you’re a novice DIYer, the project could take longer; on the flip side, a licensed and trained window contractor may be able to replace multiple basement windows in the time it takes a homeowner to replace one.

Most window screens in residential homes are designed to be removed from the inside, especially with double-hung, single-hung, and casement styles. That said, some setups require exterior removal. Older homes or custom installs may have exterior clips or brackets, and sunscreens are almost always mounted on the outside. Before removing your window screen, look at how it is held in place.

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.

Options include fiberglass, aluminum, and pet-resistant screens to suit different needs.

By replacing the worn mesh and repairing frames, restoring functionality and appearance.
