"Everything went according to plan. Crawlspace insulation was replaced and closed space was sealed up. A air inducer was also installed. The environment is totally different down there now and is much closer to the temperature of the house. I kept my vapor barrier the same."

"Insulation Commandos insulated my garage drywall, and I had a great experience working with them. Tony was especially helpful in explaining the available options and recommending the solution that best fit my garage and specific needs. He was knowledgeable, professional, and even managed to fit me into his schedule on short notice, which I greatly appreciated."

"“Jimmie was excellent. He took the time to review our concern of water leaking from 2nd floor bathroom onto our 1st floor. We were extremely concerned about what damage it can cause and Jimmie educated us on what was going on and the options to address the problems. He answered all of my questions. He fixed all issues we had and worked quickly to prevent damage to our home structure. It was a pleasure working with him.”"

"I hired Carolina Crawlspace Services to completely clean out the crawlspace under my townhome, remove all of the old insulation and vapor barrier, and install new insulation along with a stronger, higher-quality vapor barrier. I received estimates from four other companies and chose Kyle and Carolina Crawlspace because their pricing was competitive, included more work than the others, and was slightly lower overall. Kyle communicated clearly throughout the entire process, arrived on time, and did a fantastic job. The quality of the work and professionalism exceeded my expectations. I would highly recommend Carolina Crawlspace Services to anyone who needs crawlspace work done."

"Jimmie was professional, friendly and knowledgeable. Of the estimates and recommendations I received for mold remediation in my crawlspace, I thought Jimmie's approach seemed the most logical and thorough. Pricing was fair, and the service was prompt with regular communication from him and his team about progress and next steps. He even performed an extra preventative measure that wasn't included in the estimate. I highly recommend this company."

Insulation questions, answered by experts

Ductwork should be wrapped in insulation in certain locations. This includes unconditioned interior parts of the home, such as attics, crawl spaces, basement ceilings, and between floors. Duct joints should also be insulated since they're more likely to leak air than other parts of your system. Building codes in some areas also require ductwork to be insulated.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

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.

Yes, you can install insulation behind drywall yourself, but only if your walls are not finished. If your studs are exposed, installing fiberglass insulation in roll or batt form is very straightforward and just requires a few tools and some safety equipment. If your walls are already finished and you’re looking to add insulation, it’s better to hire a professional, as you’ll likely need blown-in insulation, which can be dangerous to work with and a challenge to get into the proper areas in your wall voids.
