"I contacted six companies for estimates to remove attic insulation, air seal and sanitize the attic, and blow in new insulation to R49 specs. Air-Tight's estimate was in the middle of the pack. Justin Wolfe, owner and CEO of Air-Tight LLC, gave me an estimate over the phone, answered every one of my follow up questions, and scheduled my work within the week. He stopped by at the beginning and end of the job. The crew did exactly what he said theyâ d do and were very mindful of my property. My neighbors commented on how nice they left the area. He even sealed an area under my steps and at the back of my home where Iâ d seen chipmunks enter and had an opportunity to sell more work when I asked him to check the attic above my garage but said I didnâ t need it and stayed with his original estimate. I recommend Air-Tight LLC without hesitation and am thankful I chose them."

"The crew at Bullseye did a great job adding additional insulation to my attic space. They got my home back up to the proper Rvalue, they also added some vents to help with air flow. Very professional and clean up was great. Can't wait to see the savings on my heating and cooling bills!"

"I am very happy with service we received. They explained the process involved very well. They worked with my schedule and performed tasks as stated. Left area involved clean. Heat is working much better in this cold snap. I would recommend this insulation company for anyone's need for insulation work to be done."

Insulation questions, answered by experts

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Most heat in a garage is lost through air leaks in windows, doors, and walls. This is especially true if the walls are uninsulated, which is common in garages. Consider insulating your garage before installing a garage heater to ensure the heat it generates isn’t wasted, making it less efficient.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

The average cost to install insulation is around $1,800, but you could pay anywhere between $500 and $4,500, depending on various factors. Some of the things that have a significant influence on your pricing include the following:

  • Size of the area 

  • Type and R-value of the insulation 

  • Whether your space is finished or unfinished

  • Accessibility of the area

  • Your geographical location

  • Amount of site preparation, especially for blown-in insulation

  • Whether or not you need old insulation removed

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.
