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."

I run a small remodeling company. I do wood and tile flooring, Painting, siding, windows and doors. I also install high end appliances. ie. Built in refrigerators, double ovens,etc. I've been in the industry for close to 30 years now and have a vast knowledge of the trades. Did I mention I also do insulation.

Drywall Insulation questions, answered by experts

STC (Sound Transmission Class) ratings tell you how well something blocks airborne noise. It’s a single number that sums up how much sound a material, like a window, can stop across regular speech frequencies. The higher the number, the better the sound reduction. A typical single-pane window hovers around STC 25 (where you can hear normal conversations), while well-sealed, double-pane options can push past STC 45 (which blocks out loud speech and most music). Just keep in mind that STC doesn’t cover everything—low rumbles like bass or thunder can sneak through—so pairing methods are always ideal for the most peace and quiet.

The type of insulation you need in your home depends on your location, the installation site, and your region’s climate. According to Energy Star, insulation in homes in the Southern United States should have an R-value of between R30 and R60 in attics and R13 to R25 in the floors and walls; homes in moderate climates require R values of R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require an R value of R49 to R60 in attics and R25 to R30 in floors and walls.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.
