Russels Contracting is committed to excellence in every aspect of our business. We uphold a standard of integrity bound by fairness, honesty, and personal responsibility. Our distinction is the quality of service we bring to our customers. Accurate knowledge of our trade combined with ability is what makes us true professionals. Above all, we are watchful of our customers' interests, and make their concerns the basis of our business.

"Once again and with the highest confidence, we hired Russell's Contracting to convert our back entrance into a more open, useful mudroom. As promised, they arrived on time on the expected date and started by sealing off the back entrance for dust. The demolition of the closet was first done, and then the rehab began. I was amazed at the level of detail necessary to make the new mudroom perfect. From fixing the ceiling to installing new walls, taping and sanding, painting, new baseboards, and moving the overhead light, it was fun to watch. Colby was professional, exacting, efficient, clean, and asked all the right questions to ensure we were happy with the result. The new mudroom is exactly what we wanted. In addition, we asked Russell's to help us figure out how to make our open staircase to the second floor safer. Keith, Colby, and Max designed and installed a custom-built, stair-to-ceiling railing system that looks great and provides the necessary safety we were looking for. They also made it removable to accommodate large objects up and down stairs. The amount of time they spent was crazy, and the amount of math they did to ensure it was plumb and solid was above and beyond our expectations. My house was built in 1933, and this railing system looks like it could have been original to the house. It is a masterpiece. Everyone at Russell's Contracting we have met and who has worked on our house has been exceptional. You can stop scrolling for contractors; call Russell's."

Meeting somebody, being invited into their house, and listening to their ideas of how they would like to transform their space to better suit their needs excites me. It brings me immense pleasure to be welcomed on an idea based visual journey in creating a customized dwelling in order to improve the quality of function in somebody's daily home life. Bringing ideas to fruition is my specialty. With equal enjoyment in making those popcorn ceilings that you've adored for so long disappear in an array of smoothness, gutting the kitchen where nothing seems to fit anywhere, including the cook, and installing cabinets and lights that transform the "heart of the home" into a space you don't want to step out of, or erecting that garage and mudroom to get your cars out of the weather and the clutter out of your foyer. At Magic Frog Carpentry & Woodworks I live in a solutions based mentality.

"Adam did an excellent job building our garage from the ground up. He was excellent to work with. Not only was he very professional, so were the subcontractors that he hired. Everyone was knowledgeable, helpful and friendly. Our project required that a road be built to accommodate large trucks in the springtime. The project stayed on track and proceeded smoothly. We were never left wondering “what’s next?” Adam has great communication and stayed in touch to make sure we knew what was coming up and when. I would definitely recommend using Magic Frog Carpentry."

FAQs for addition to existing structure building service projects in Rochester, NH

Yes, hidden rooms are legal, as long as they meet all local building regulations. If you sell your house, most states require homeowners to disclose full houseplans, which would include any hidden rooms.

If your secret room is a safe room, it should contain a means of communication aside from a cell phone, such as a shortwave radio. You should also have plenty of drinking water, a portable generator, emergency food supplies, blankets, pillows, flashlights, batteries and a first aid kit.

Any time you update your home’s square footage, you increase its value, but a secret room is a niche feature that doesn't rank high on every buyer’s list of must-haves. Investing your money in remodeling more common living areas like bedrooms, bathrooms, or kitchens will have a higher ROI than adding a secret room. Many secret rooms can act as entertainment spaces (think a game room or wine cellar) or quiet spaces (a library or study), so when building your secret room you may want to consider its versatility for when you’re ready to sell.
