Our Attic and Crawlspace Insulation Services

Reconstituting an attic or crawlspace usually includes the removal of old, inefficient, or contaminated insulation, and always includes the installation of new, more efficient, pest-free insulating material. Changing your attic insulation will help your home keep an ideal climate and save you money on energy costs.  Add crawl space cleanout to insulation services so you can improve your home’s air quality. We offer two types of insulation batt insulation which is usually made of fiberglass or mineral wool (also called rock wool). We also offer blown-in otherwise known as loose-fill insulation. If cost is an issue look for PSE insulation rebates that can help with the cost.

Types of Crawl Space and Attic Insulation we Install

Batt Insulation

Batt insulation is made of fiberglass or mineral wool also known as rock wool. This type of insulation is commonly used to insulate floors, walls, ceilings, and attics.

Unless it is damaged batt insulation can last 80 to 100 years in most houses before it needs to be replaced. That being said fiberglass batts can start falling after 15 to 20 years, so if your insulation was installed a decade ago you might want a home energy audit or inspection.

The short answer depends. If your insulation has water damage or is rodent-infested then you should never place new insulation over it. If none of this exists then you can install new insulation over the old one. 

Blown-in or Loose Fill Insulation

Blown-in or Loose-fill insulation consists of small particles of fiber, foam, or other materials. You can easily add it to attics and walls without much hassle. This type of insulation can seal small spaces as it settles, which can block small spaces where cold air would otherwise be let in.

Blown-in cellulose insulation will last 20 to 30 years under ideal conditions. There are a variety of factors that can affect the lifespan of this method of insulation. This is why we always recommend it installed by a professional insulation contractor.

The higher the R-value, the better the thermal performance of the insulation. The most common R-value for attics is R-38 or about 10 to 14 inches, depending on insulation type.

Insulation Benefits and Process

Insulation Replacement Benefits

The many benefits of the attic and crawlspace insulation reconstitution include increased heating and cooling efficiency, decreased energy bills, qualification for tax rebates, and a healthier living or working space. Our customers have greater peace of mind knowing their home or business will cost less to heat and cool and those disease-carrying rodents, insects, and other animals will no longer put the health and safety of their home or business at risk.

Crawlspace Clean-out

Before performing any work, the entire area and pathway leading to your crawlspace are prepared, protecting the rest of your property from further contamination. Once inside the crawlspace, technicians remove all contaminated insulation, vapor barrier, debris, and rodent or other animal or insect carcasses. We use a HEPA filter vacuum to remove all small debris and dirt, eliminating the possibility of air contamination and maintaining a healthy environment. We then apply a decontaminating and deodorizing spray to sanitize the space. All contaminated insulation, feces, vapor barrier, and debris is placed in specialized disposal bags to trap all contaminants.

Before installing new insulation and vapor barrier, Redi National Pest Eliminators seals all crawlspace entry points used by rodents, insects, or other animals. The most important part of this process is to determine how pests entered before, so we can seal every entry point to keep them out in the future permanently. Once the cleanup, decontamination, and exclusion work are completed, the technician will install new insulation and vapor barrier to state, county, and city code regulations.

Attic Clean-out

Before any work is performed, we prepare the entire area and pathway leading to your attic to protect the rest of your property from further contamination. Then a decision about replacement insulation type is made. The two attic insulation types are loose-fill (blown-in), or batted, which comes in strips or rolls. For loose-fill removal, we use a specialized vacuum system positioned outside the home and connected to approximately 150 feet of hose. A high-volume filter bag collects the old insulation and prevents further contamination, with the waste then packed into 1 to 3M industrial-strength trash bags and properly removed. We then use a HEPA filter vacuum to remove all remaining contaminants.

Before reinstalling new insulation, our technicians seal all attic entry points that could be used by rodents, insects, birds, and other animals in the future. Once we’ve thoroughly cleaned the attic, decontamination/deodorizing spray is used to further sanitize the space. Our team then installs new blown or batted insulation to code, making sure proper ventilation is in place.
