"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!"

"I could not have been happier with the service. Miguel was friendly, very competent, accommodating and respectful. Amy was great for scheduling. Miguel was on time and put up a street mailbox to my wife's glee. We will definitely reuse this service for our future needs. My highest recommendation."

"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."

"I was searching for someone to install drywall on one living room ceiling constructed with old split lathe and plaster (plaster already removed). I browsed Home Adviser for possibilities and ran across Dependable David. His outstanding reviews from numerous customers stood out among all others. Surprised by such a consistent, positive experience from individuals that he worked for, I decided to give him a try. After his work was completed, here's my thoughts: Prompt arrival. Methodical, plans ahead. Steady worker. Cleans up messes. Completes work without delay. Good quality. Kept within prior estimated price. I'm happy to join all the others here and give a 5 out of 5 to David!"

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

Modern steel doors incorporate protective coatings and finishes that significantly reduce rust potential. These treatments create effective moisture barriers when properly maintained. Small scratches or damage should be promptly addressed with touch-up paint to prevent moisture from reaching the underlying metal. 

Doors in coastal or high-humidity environments benefit from additional protective measures and more frequent inspection. With proper care, most steel doors resist corrosion for decades.

Steel doors provide superior resistance against forced entry attempts compared to fiberglass alternatives. The inherent strength of steel creates a formidable barrier that resists impacts and tampering more effectively than composite materials. 

While high-quality fiberglass doors offer reasonable security, steel provides an exceptional strength-to-weight ratio and structural integrity. For maximum protection, look for steel doors with reinforced strike plates and multi-point locking systems.

Most manufacturers provide warranties covering manufacturing defects for periods ranging from five to 15 years, depending on the product line and quality tier. Hardware components often carry separate warranty coverage, often for shorter durations. Installation services may include workmanship guarantees covering proper fitting and operation. Always review warranty documentation carefully to understand coverage limitations and maintenance requirements that might affect warranty validity.

Provided your existing wood frame remains structurally sound and properly aligned, professional installers can often adapt a steel door to fit. The process requires careful measurement and potentially minor modifications to accommodate the new door's specifications. The frame must provide adequate support for the heavier steel door construction. A qualified installer will evaluate your current frame's condition and recommend appropriate adjustments to ensure proper function and security.
