"The installation of our new garage door went perfectly. The team worked efficiently, cleaned up after themselves, and made sure everything looked great. They even showed me how to use the remote properly."

"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."

Universal Windows Direct of Manchester serves all of Central and Southern NH; we specialize in windows, doors, siding, and roofing. We carry our own exclusive brand of windows and siding called Unishield, and we have some of the best warranties in the industry. We are a preferred Owens Corning roofing installer. One of the key points that differentiates our window products from our competitors is that we use only virgin vinyl, built in one solid piece custom to each opening rather than standard sizes modified during installation. This creates a seamless fit that will not bend, crack, or warp over time. We also use the exclusive super spacer in between the panes of glass instead of metal, which is used by most window manufacturers. This amazing material almost completely diminishes any heat or cold transfer within the panes of glass, keeping you and your home comfortable and energy-efficient no matter the season!

"Quick and efficient installation with zero hassle. "

"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. "

Security Doors questions, answered by experts

The vast majority of hinges are symmetrical, and either side of the hinge can go on the door or the frame. Occasionally, you'll find a hinge specifically made for right or left-handed doors with different attachment hardware or larger plates on one side. In most cases, the large side of the hinge goes on the frame.

It is possible to install hinges backward, so be careful when placing them. Position the hinge so that the hinge pin faces the direction the door will swing. For example, if you're standing on the side the door will open into, the pin should be visible. Be extra careful when installing exterior doors, as placing the hinges on the outside for an outward-facing door makes your home much easier to break into.

Yes, prehung doors include a door jamb. Prehung doors are sold as a single piece with the door frame already constructed, including the hinges. The only part missing is the trim, which you add after fastening the door. They are more expensive than slab doors but are quicker and easier to install. Prehung doors come in an array of sizes, so there’s likely an option to fit any doorway you need.

Which way your garden gate opens mainly comes down to preference. While other types of gates, like one leading from the sidewalk to your property, should swing inward rather than outward to avoid opening into a public space, you don’t have to worry about such an issue in a backyard garden. However, a garden gate that swings inward may still be useful when carrying heavy loads into the space, like a wheelbarrow filled with mulch or heavy wood boards for building new garden beds.

Yes, you can clean door hinges with vinegar. The cleaner your door hinges are, the less likely they are to cause that annoying squeaking sound. Simply fill a container with equal parts water and vinegar, dip a microfiber cloth in the mixture, and use it to clean the hinges. You can do this while the hinges are connected or remove them, and wash them piece by piece.

Wood is more susceptible to damage than metal, and a wood door can benefit from upgraded locks, screws, and strike plates. Additional features like security doors, latch keys, and deadbolts are also a plus. Installing a comprehensive security system will also boost your home’s protection and make you feel safer.
