"Over the years I have hired Joseph and Sons several times. Angelo knows his work and has always been professional and courteous. They recently installed fencing on a retaining wall, replaced back fence, re-did my walkway and several other projects. Angelo and his crew made sure that everything was done correctly. I would hire them again and would recommend them 100% for any project."

"James and his team did a complete renovation of a townhouse that had been neglected over many years. Tear-out of old flooring and fixtures. Installation of new laminate flooring, new paint throughout, new light fixtures, complete new bathrooms, complete new kitchen and exterior painting and power washing. All word was done professionally and thoroughly and at a fair price. We worked together on planning and acquiring the materials. They are very easy to work with and they got the job done in a timely fashion."

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