"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."

"The company could not have been more reliable. Estimate was thorough and detailed, installers were prompt, neat, professional, and considerate. They took time to explain all equipment to us. Follow-up inspection was timely and identified two issues needing correction, and that work was immediately addressed and completed."

"I hired Airtight to spray foam insulate my rim joists and add to/correct the existing insulation in my attic. Ryan conducted the free home energy audit and was very prompt in following up with an estimate. He was very honest about the work I needed done and I was incredibly pleased with him and the crew's professionalism. I highly recommend reaching out to Airtight to see where they can help you."

Insulation FAQs, answered by experts

Water freezes at 32 degrees Fahrenheit, but the actual temperature that can cause frozen pipes can vary. Generally, it takes 12 hours for pipes to freeze at 32 degrees Fahrenheit.

Uninsulated pipes can freeze if it’s 20 degrees Fahrenheit or colder for over three hours. If your pipes are insulated, it can take six hours or longer for pipes to freeze. Note that some pipe types freeze more often than PEX pipes. Copper pipes freeze more often because the copper conducts energy and loses heat quickly.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

Open-cell foam insulation has a life span ranging between 15 to 25 years when well cared for. However, the material may degrade sooner in areas with high humidity or after prolonged water exposure. Proper installation and maintenance can maximize its longevity but requires close monitoring. Closed-cell foam insulation has a longer life span of 30 to 50 years.

Most insulation lasts 15 to 20 years, but it really depends on the type of insulation. Spray foam is a permanent insulation material that can last up to 100 years. Fiberglass and cellulose typically settle, shift, or deteriorate around 15 years. Once your insulation reaches the 15-year mark, it's time to check it for signs of needing to be replaced.

Yes, doggie doors, like all entrances, can let both hot and cold air into your home. However, as with any door in your house, you can take steps to weather-strip your pet's entrance to prevent air leaks.
