"I could not be happier with the job Tim and John did installing new windows. It was difficult to find someone to cut a hole in the side of my house as these were not replacements, but a new installation. The windows and trim match the existing windows. Couldn’t ask for a better experience and outcome., I can’t recommend Tim enough."

"Our experience with Jim is nothing but positive. We hired hIm to do built-in cabinets/ bookcases in our office and mudroom. He did exactly what we asked for and the finished product was perfect. We are very pleased with the work. Jim is professional and detailed oriented. He is reasonably priced and was worth every penny for the quality of the work. Since our first project he has done multiple small projects for us like building cabinets in the garage and basement, installing doors, doing some siding work. We have already have recommended him to friends and family."

Customers say: Terrific value

"They showed up on time each day, were very knowledgeable of the work they performed. Showed up for the quote when we scheduled the first meeting and we were very impressed with the overall experience. The deck they built was spot on and perfect for our needs. They did make some recommendations as to how it would look and work better for us and we went with their decisions and are so happy and impressed. They were very neat about their work and very easy to talk with. I would never use anyone else, and HIGHLY RECOMMEND them for whatever you need. So great to work with."

"Ben was extremely personable and clear with his expectations and planning for our exterior door installation project. He was communicative with his scheduling and accommodating around our own. He and his partner were quick, professional, and took very good care of us and made sure everything was as secure as possible, above and beyond our expectations. Great job."

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