"Jag installed spray foam in the basement, air sealed the attic, and sprayed fiberglass in the attic. The work was done as scheduled. The obviously experienced crew was fast and friendly. The cleanup was great. I definitely would recommend Jag."

"My only problem was that the salesman promised parts of the install that weren't in keeping with how the roof was actually installed. (i.e. said would that if temps. were below 40 degrees, the shingles would be kept in a heated van then installed with extra sealant and use of a heat gun) I would wish that the salesmen would know how the work is actually done and not give customer assurances that are not going to be carried through."

"Mark was very professional and gave a complete explanation of the estimate and work involved. while only one man showed up on the date scheduled for insulation, he completed the exterior walls foam insulation work including the interior basement rim in the day as promised and was very courteous and thorough. I have noticed quite an improvement in the warmth of my home and especially since we have had 2 very cold weeks since Christmas. negative degrees! I am very pleased with the company and the work."

"I was extremely satisfied with my experience with Airtight Services. Brad answered my many, many questions completely and patiently. He went way above and beyond to ensure that the insulation project was completed on time and better than expected. In fact, the entire team did a great job while also being wonderful to work with. Besides the blown in insulation they also installed a bathroom fan and kitchen fan and vented both out through my roof. I highly recommend using this company."

Insulation FAQs, answered by experts

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

On average, insulating an attic costs about $2,500, with a typical range of $1,500 to $3,500. The final price often depends on the attic's size, with costs generally falling between $1 to $3 per square foot. For example, insulating a 1,800-square-foot attic would likely cost between $1,800 and $5,400.

If the project involves removing old insulation, this can add an average of $900 to the total cost, bringing a full removal and reinsulation project to around $3,000.

Several factors influence the overall cost:

  • Insulation Type: Prices per square foot vary significantly by material.

  • Reflective: $0.50–$1.50

  • Blown-in: $1–$4

  • Batt: $2–$4

  • Loose-fill: $2–$5

  • Spray foam: $2–$5

  • Structural insulated panels (SIPs): $4–$7

  • Project Complexity: Factors like sealing air leaks, poor attic accessibility, and required inspections can add to the cost.

  • Removal Issues: The discovery of mold, asbestos, or pests during the removal of old insulation can substantially increase the price.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.
