"Bob has done numerous projects for our old house over the years mainly carpentry, and most recently to replace cedar siding on a large area of the house. Bob does excellent carpentry and finish work and is an extremely hard worker. He has also done wood gutter repair, cleaning and sealing, hung exterior doors and installed exterior wood railings for us. The various projects have involved a significant amount of high exterior painting. He has a wide range of skills and excellent problem-solving ability. Because of this history, we have a lot of trust that Bob will do an excellent job at whatever project he accepts. "

"Torin and his team did a wonderful job upgrading our original 1980s kitchen. He was flexible with its construction ‘quirks’ and helped me find materials within my budget. Kitchen remodel included cabinets countertops & lighting. Torin is detailed and thorough. He shows up on time, is clean and personable. Throughout the project, he took on smaller fixes including replacing my bathroom faucet, fixing the drafty front door & hiding the TV cable wires behind the wall. Overall very satisfied with his work. "

"We hired Jim Longden in 2023 to install flooring in our dining room, kitchen, and downstairs bathroom. He also installed a vanity, sink, and toilet for us. He claimed he was capable of doing that work and we hired him in good faith. He made some egregious errors which caused flooding and water damage that was discovered in 2024. Uber our toilet the blocking was gone and the hole under our toilet was too big. He also never sealed the toilet in the floor so you could just wiggle it around in the bathroom floor! A professional contractor would never make these mistakes. Water leaked underneath our bathroom, kitchen, and dining room floors and they all had to be torn out. We had to pay for the repairs out of our own pocket so we are currently $30,000 in debt. We are still fighting with his insurance to pay for this! DO NOT HIRE THIS MAN. "

"Excellent professionalism! Very skilled, but willing to do many different “handy tasks” like curtain rods and hanging pictures. He easily put together small furniture from Amazon, but also does cabinetry, drywall, etc. I highly recommend Blake cleancut services!! "

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