"Mr Mendicino promptly responded for the assessment and repair of my sliding door. He was competent and pleasant. I intend to make another request to him regarding the possible further minor repair. I most definitely would refer him to others that might be in need of his services. Thank you again for your referral. Ruth Bredbenner"

FAQs for doors (exterior) installation and replacement projects in Hillsborough, NJ

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.
