"We are very pleased with the interior painting work that Farrell Painting performed for us. We contacted them from an add in the Granite State News. Chuck came over to see the job and gave us an estimate and provided references. We called all 5 references and they all recommended Chuck and his crew. We gave Chuck a two week window when we would be away, and he accommodated us. When we arrived home we found the job completed, and we were very pleased with the results. They did excellent work and you can trust they will take good care of your home."

"Gary was quick to reply to my request for a quote and got right back to me. He was very reasonably priced. He showed up when he said he’d come, was friendly, got right to work. He did a great job even in my little cupboard under the eaves that was not easy to crawl in and out of! He did a good job with clea up. I would certainly recommend him and hire him again."

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."

Drywall Insulation questions, answered by experts

Blown-in insulation works, but only for unfinished attics. Also, it isn’t the longest-lasting nor the most effective option. For better options, look into spray foam insulation or natural fiber batts. They typically have a longer lifespan, better heat resistance, and stronger sound-proof abilities. Spray foam insulation costs about $1.25 to $1.50 per square foot, but can go up to more than $4 per square foot. Fiber batt pricing varies depending on the material.

No, you should avoid using antifreeze in your outdoor spigot to prevent freezing. Antifreeze can contaminate your water supply and harm the environment. Instead, employ safer and more effective methods for winterizing your spigot, such as draining the spigot and using insulation, to protect it from freezing temperatures.

Opting for insulated ducts can lead to significant long-term savings on your energy bills and contribute to a more efficient HVAC system. The precise amount you can save depends on various factors, including your climate, usage patterns, and the insulation's quality. However, on average, insulated ducts can result in savings of up to 20% on your annual heating and cooling costs, according to ENERGY STAR®.

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.
