"I want to give my highest possible recommendation for Craig at Mel Martin Windows! I hired them when I found significant rot and decay in the wood around my front door. Craig came to our home, evaluated the situation and created a great plan to fix everything. We ended up replacing the wood around the door and installing an entirely new door. Craig did an exceptional job at recreating the decorative brick mold we had on the door frame by using PVC products. He corrected all the previous issues and now gave us a new solution that will withstand the weather for years to come. Extremely happy with his professionalism, punctuality, flexibility and pricing. He is a true craftsman and a pleasure to do business with. Very pleased with how our project turned out."

"James gave me the lowest quote and installed my floor two weeks from when I signed with him. I wanted the floor done by Easter and he delivered! It turned out beautiful! We couldn’t be happier!"

"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. "

"Torin and Jack were so easy to work with, and they did an excellent job with our basement. It?s clear that Torin is very passionate about his company and the work that they do. We had to re-finish our basement after a pipe burst, and Torin made it easy to meet the requirements of our insurance agency. He provided all of the paperwork we needed in a timely manner, and was able to recreate our previous setup to the satisfaction of the insurance company. We also appreciated Torin and Jack?s flexibility with our schedule. They were very communicative and always let us know when they had openings ahead of our scheduled sessions so that we could continue to make progress on the build. We felt very comfortable with them in our home so often had them come while we were at work. Torin was very easy to work with and we highly recommend his company and will be using them again for future projects. Bonus - Torin and Jack both like dogs, and were super sweet to our pup! She loved having them "

"Conlan and his crew did a great job! He was onboard and helpful with changes I wanted to make during the building process. He was very professional and work was completed in a timely manner…they even worked in the rain. They cleaned up every bit of debris from the job and left me with a beautiful new deck ready to use. Good quality work is hard to come by these days at an affordable price, but there was no price gouging from his company. I highly recommend Shoreline and would use them again!"

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