"We were extremely happy with the work performed by H&M. Moises, Hector and crew were courteous and did whatever needed to please us. They did most of the renovation in our condo......painting, installation of bathroom cabinets, sink, installed tile floor, etc. They also installed vinyl flooring in our kitchen, living and dining rooms. They had a plumber replace our heating baseboard, I would highly recommend H&M if you want excellent work done!!"

Small jobs welcome

"I took a chance and hired Mr. Handyman to fix my storm door. Kevin removed the door, worked his magic and reinstalled the door, and now it closes properly. I asked him if he did electrical work I needed a pagoda fixture that was in the ground near my driveway moved in about 3 feet. He dug a trench and installed the new pagoda fixture. I needed some wooden spindles from my deck reinstalled. He not only reinstalled them but reinforced all the spindles and also the railing. He was here for 5 hours. This is a great company...they sent an email with a picture of Kevin with his bio.A little pricy, they charge by the hour, but everything that needed fixing was fixed."

FAQs for doors (exterior) installation and replacement projects in West Islip, NY

If your entry bakes in direct sun, fiberglass is the clear winner. The material shrugs off extreme heat, stays energy-efficient, and won’t warp or fade the way wood sometimes can. Paired with low-E or UV-blocking glass, a quality fiberglass door keeps hot air out, cool air in, and should serve you reliably for roughly two decades.

A seasoned door pro can hang a replacement door in two to four hours—mounting the slab, tweaking the fit, and adding hinges, knobs, and weatherstripping. If the jamb needs repairs or you’re cutting a brand-new opening, plan on extra time so everything lines up and seals tightly. Either way, most projects wrap up in a single afternoon.
