When do I need services?

Why do I need new insulation?

Chuck Henrichsen

Better air quality, improved energy savings, and a healthier home are just a few of the reasons clean insulation is important.

How do I know when it’s time to replace my insulation?

Chuck Henrichsen

Do you have nasty smells in your home that you can’t find the source of? Does your air conditioning bill fluctuate sporadically? Is there mold in your crawl space? If so, it’s time to replace your insulation!

My Floor Is Cold!

Crawl spaces that are poorly insulated or contain bad insulation allow heat to escape from your floor, leading to cold floors in the winter. If your crawl space does not contain enough insulation, or is not properly sealed, the cold air from underneath your house will create a chilly surface for you to walk on.

My Crawl Space Stinks!

Are strange smells coming out of your crawl space? Crawl spaces often start to smell when they’re not properly cleaned. Mildew, soiled insulation, or a rodent that found its way into your crawl space can cause your crawl to smell if not carefully maintained.

I Need to Save Money!

If your crawl space or attic is not properly insulated, your HVAC system will work overtime to keep the inside of your home a comfortable temperature, costing you more money. Insulating your attic and crawl space will keep the warm air in during the winter, and the cold air in during the summer.

Benefits of Clean Insulation

Temperature Regulation

Insulation works to prevent the transfer of heat through the walls, ceiling, and floor of your home. When some rooms are better insulated than others, the air temperature from room to room can change dramatically. Cold floors, cold walls, or excessive heat in upstairs and attic areas are signs that your home is not well insulated.

Unwanted air transfer causes your heating and cooling systems to work overtime to compensate for the energy loss. The installation of new insulation, however, in key areas of your home, helps regulate the house temperatures and reduce your energy costs.

Keep Moisture Out

  • Holes or cracks in an attic or crawl space allow moisture and water to enter into the structure of your home. Mold and mildew thrive in the dim, warm conditions of the attic, crawl space, and wall cavities. The presence of mold and mildew drastically decrease the air quality of your home and causes decay to a home’s structure.
  • Prescriptive air sealing, duct sealing, and the correct choice of insulation can lock out moisture and keep your attic and crawl space dry and toxin free.

Save Money

Homes that lack proper insulation spend more money on their energy bills. Conversely, investing in attic and crawl space insulation creates an average energy savings of 30% – 80% (depending upon the condition of old insulation), simply because the insulation enables their homes to be more energy efficient. Because of this, the insulation installation pays for itself within months.

Types of Insulation We Provide

Spray Foam Insulation

Spray foam insulation is made from two types of composite material: polyurethane, and isocyanate, an organic compound made from tweaking the molecular structure of isomeric cyanic acid. When sprayed out of the tip of the spray foam gun, the substance gradually expands, filling in the cracks and crannies of your crawl space or attic before curing. Spray foam insulation is the most effective material for insulating your crawl space or attic available.

Fiberglass insulation is usually installed as large segments of insulation that are rolled or laid out onto a surface, such as flooring, ceilings, or in wall cavities. However, blown fiberglass is becoming more and more popular, comprising one of the main insulation jobs we’re asked to do. This type of insulation is made of a mixture of natural sand and recycled glass.

Cellulose insulation is made from recycled paper products, primarily newsprint. It’s recycled material content is very high, generally between 82-85%. The manufacturing process reduces the paper products to very small pieces, which are then fiberized and mixed with a flame and insect retardant, usually mineral borate or ammonium sulfate. Cellulose insulation is primarily found in pellet form as a blown-in insulation, but can be manufactured in batts as well.



Cotton has become a favorite of the environmentally friendly community. Recycled blue jeans have been used in its production, as well as other natural cotton fibers gleaned from industrial scrap. Most cotton insulations consist of 85% recycled cotton and about 15% plastic fibers, which are generally treated with boric acid as a flame retardant. Cotton insulation is non- toxic, and can be installed without respiratory or skin exposure protection. Unlike fiberglass insulation, no reports have been made of itchiness or burning of the skin when in contact with cotton insulation.

Denim Insulation

Using recycled jeans, post-industrial denim and cotton, denim insulation is an eco-friendly insulation material for your home. Without the itchy fibers that many other types of insulation contain, denim insulation is just as effective as fiberglass and cellulose insulation. While it is more expensive than other types of insulation, if you’re looking for an earth-friendly insulation material, denim insulation is the type of insulation for your home.

What Our Customers Say

In May 2017, Clean Crawls insulated my crawl space with spray foam. I was impressed by the job they did — the two-man crew who came out were clearly experienced, and they did good work in a tight space. The salesman who came out to look at the house and give me a quote was also helpful. He communicated with me clearly and returned calls and e-mails promptly. I was charged exactly the value of the original bid with no fuss, and the price was lower than what it would have cost me to purchase do-it-yourself spray foam kits. I would certainly do business with Clean Crawls again in the future.


The crew of two arrived on time. The lead explained in detail to me what they were there to do. It turns out that there was a misunderstanding. A phone call to Jeff (salesman) and everything was adjusted on the fly with no issues. It really was that easy. The crew went in, did the prep work and offered to show me the work they had done before spraying in the insulation. I did ask the names of the two crew members but unfortunately my memory is failing me at the moment. I admit that initially I was skeptical when Jeff said it would take them 3 hours to finish. But they were done in 90 minutes! When they told me they were done, I must have looked at them funny because they insisted that I check their work. It was all and more that they had promised. I was so impressed that I tipped them and thanked them over and over again. Now here is a "no kidding" moment. I had requested an estimate from another company and they never called me back. Well, guess who showed up today unannounced? I told them that the job was already done. The salesman asked if he could look in our attic just to make sure we got what was promised. 10 minutes later he came back down and said it was "a pretty damn good job". Shook my hand and left.
