"We had a top to bottom, excellent experience with the local team from Universal. My wife and I had an in-home consultation, a measurement and the install completed in a little over a months time. As stated in a prior review, the cost is reflected in the quality of the workmanship. Our family could not be happier with our experience. Big thanks to Kyle, Ron, Mike and Dennis for the top-notch service. I can wholeheartedly recommend Universal Windows Direct to any homeowner in need of a new door, installed quickly and by a friendly, knowledgeable and friendly staff. Thank you again!"

"I have hired Hi Tech Window and Siding over the years to install windows throughout my house, install siding on my house, as well as entry doors and a sliding door that opens to a beautiful deck which they also installed. Needless to say, my wife and I highly recommend Hi Tech. The professionalism exhibited by Hi Tech is second to none. They use quality products, employ knowledgeable, professional craftsmen and most importantly stand behind every installation 100%. I am proud to recommend Hi Tech Window and Siding to everyone who is looking for a quality contractor. There is no better."

"They installed some windows and vinyl siding on my home. They were very professional, communicative, paid great attention to detail, and left the work site clean. Definitely worth the investment."

"Phil is a true professional who does top-notch work. I hired Phil to replace the wooden trim around two garage doors and a center entrance with PVC. Phil was reasonably priced and his attention to detail and standard for high quality work is second to none."

"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!"

"We bought our first home this year and absolutely love it, but we quickly learned it needed more TLC than we realized. We could see rot on our exterior trim and clapboards, plus a missing gable vent. From the very beginning, Shawn impressed us. His estimate was incredibly thorough, and it was clear he’s a true professional. As new homeowners, we felt confident putting our home in his hands. We are so fortunate we hired him. Shawn showed up early, worked late, and demonstrated meticulous attention to detail in everything he did. When we discovered the rot was far more extensive than we thought, he never made us feel stressed or overwhelmed—he walked us through our options, offered solutions, and helped us make the right decisions for our home. The quality of his work speaks for itself, but just as important, his communication, reliability, and integrity made the experience exceptional. We will be working with Shawn for all of our home’s needs. We actually missed him when he left !"

"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."

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