"The company rep came out as scheduled and conducted a thorough and professional estimate for the added insulation. Then the installers came out and again did an outstanding job adding insulation to our attic. They worked well as a team and did an excellent job."

"Matthew did a thorough quote at my house shortly before Thanksgiving. Matthew was very professional, on-time and friendly. The technology was impressive as you could see the ?cold spots? around my attic space. I plan to execute the job after the holidays. I highly recommend Matthew and Insulation Commandos if you need any insulation related work."

"Eddie fully explained the benefit of the planned level of insulation for our attic, uses quality Owen's Corning fiberglass blown in insulation and recommended adding an roof vent attic fan to remove heat/moisture in the summer and moisture in the winter. Currently, we have passive eve vents and roof ridge vent. Cooling inside of the roof with air flow should help extend the life of the shingles by removing stagnant hot air. We chose an electric roof vent fan rather than solar because of the # of cloudy days in our area and humidity. Everything was done quickly on scheduled time, all contacts were professional, kept our home as clean as possible and swept up loose insulation. Pricing was very competitive plus we qualified for TVA energy rebate."

"James and his crew did a phenomenal job with the insulation job! His communication was great. Very honest and upfront about what can and can’t be done. No trying to finesse an upsale or anything like that. I'm very glad we went with James and I'd highly recommend him to anyone looking."

Insulation questions, answered by experts

Closed-cell foam may come with a higher price tag, but it’s worth the investment because of its strength and durability. This material offers excellent thermal and moisture resistance, contributing to its long life span. Its construction enhances energy efficiency, which can lead to reduced heating and cooling costs over time.

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.

Plaster itself has a higher R-value than drywall. However, there are other considerations surrounding plaster and insulation. As a general rule, it's easier to obtain consistency in insulating value and quality when working with drywall rather than plaster. Plaster walls often don't contain any insulation behind the wall covering by design, and careful evaluation is necessary when choosing to add it.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.
