"After a year and a half with my crawlspace encapsulation everything is going good! I was very nit-picky about many details and everyone I dealt with was courteous, professional and communicative, had 1 little issue that was immediately resolved and the techs that got it completed did a great job. I was very pleased with the way they set up a barrier around my pool to prevent any debris from getting into it too"

"The estimator/salesperson Jeremy was excellent. On time, knowledgeable, understood the issues we had and spent a lot of time to recommend the best solution. The install crew of Shawn H and Dustin were prompt, professional and efficient. I would recommend this company and will use them again for my insulation needs."

"Upstairs would not cool down with the unit on, called indoor mechanical and Robert and Josh came out within 24 hours. Did a lot of testing and looked everything over and turned out needed and entire new unit. Had a price same day and an appointment set. They were on time, professional, cleaned and made sure everything was running right and even checked to make sure the kids rooms had good air flow to keep them comfortable during these warm spring days in NC. Could not ask for a better outcome to a crappy situation that is going to happen eventually when you own a home. Indoor mechanical will be my go to for anything they offer."

"My experience was great. Steve kept communications open during a period of inclement weather. When the weather cleared Steve and one of his crew came to access the job and determined that they could do the job right then, so they got to work and installed the gutter with the highest level of professionalism and skill. I will recommend Blue Seamless Gutters to anyone without reservations."

Insulation FAQs, answered by experts

Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.

It's essential to use insulation materials specifically designed for air ducts. Common types of duct insulation materials include fiberglass, foam board, and reflective foil. These insulation materials have the right properties to withstand the temperature and airflow conditions within the ductwork. Using the appropriate insulation not only ensures efficient temperature control but also prevents potential safety hazards or the release of harmful particles into the air.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

A radiant barrier is a form of insulation topped with a reflective material designed to keep homes cool during hotter months. It is generally considered worth the investment if you live in a hot, sunny climate, as the cost can be recouped over time through lower energy bills. Installation costs typically range from $0.10 to $1 per square foot. After installation, homeowners in warm climates may save between $7 and $15 per month, potentially reducing their electric bill by 5% to 10%. The exact savings will vary depending on your location and the type of barrier chosen.
