"Victor and his crew did a beautiful job removing border wall paper and painting of our three bathrooms. He also removed all three bathroom vanity tops and installed new ones after also reversing a door in our master bathroom. All the work was neatly done, showed quality workmanship and was thoroughly cleaned up when completed. He is fair and honest and his workers are courteous, and show respect to your home. He keeps his word and fixed small problems as they arose with professionalism. I look forward to hiring him in the future."

"Excellent job. Showed up on time and did a nice clean up after. This job was to replace a hole in the ceiling with sheetrock and painting. Very good work; I can't even see where he patched it, so smooth. I will definitely use James Agate Contracting again."

FAQs for doors (exterior) installation and replacement projects in Sag Harbor, 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.
