"They replaced my bathtub, installed a new vanity, put in new lights and painted a wall cabinet. Not only were they punctual, but very polite and reasonable. I highly recommend them and will use them in the future."

"Brad Armel of BKM Contracting called me in response to an online form that I filled out on another website.  He came after another contractor who spent most of his time trying to get me to replace the entire deck; we didn't want to given all the expenses that we have had after Hurricane Sandy.  Brad quoted a reasonable price, proposed the power-washing, scraping and painting, which is what we really wanted.  He also quoted a price for replacing the bifold doors on my wife's closet with sliding doors, which also including painting it.
They came when they said they were coming, installed the sliding doors and power-washed the deck on the same day.  It took them a week or so to come back to paint the deck, but this was due to a week where it rained almost every day; we needed two or three dry days before the painting.  Brad's partner, Mike, came stained the door and painted the deck in one day and came two days later to coat the closet doors with polyurethane to seal them.
Brad and Mike did everything that they said they would do, did a quality job in a timely fashion, even coming on Sunday to make up for the delays that they weather had caused.  I would use them again without hesitation."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

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.
