"Aubrey & Son Home Improvement came to install flooring, framed and installed interior French doors. The attention to detail, professionalism, friendliness and the fact they left with the areas spotless was greatly appreciated and they did an outstanding job though and through. I will be calling them again in the near future for other repairs!"

"Kevin was great, he was very responsive on a Saturday and came to hang a new door for me the next day. The installation was more complicated than I originally anticipated. The hinges, deadbolt and door knob did not align with the existing cut outs. Kevin did a great job making the door look like it was pre-hung on the existing frame."

"We cannot say enough good things about Nick. He replaced all of our exterior trim and it looks incredible. It was a huge project and Nick did not disappoint! Nick and Marshall are both so kind, hard working, detail oriented and a pleasure to work with. They gave us updates every day and were very transparent about their progress along the way. We cannot wait to have NP Carpentry back for a future project!"

"Shawn did an excellent job replacing and installing vinyl skirting in the back of my mother’s mobile home. He also replaced boards around her shed. Both jobs were a job well done and he didn’t break the bank. I knew I wanted to hire Shawn at the time of the free estimate. He took out his measuring tape, measured, and looked at the project, stated what needed to be done with replacing the skirting, and sent the proposal. I signed and he did an excellent job. I would have Shawn again to do future projects."

FAQs for doors (exterior) installation and replacement projects in Dover, NH

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.
