Why Choose Insulation Service for Your Crawlspace Insulation Project?

When you select Insulation Service for your crawl space insulation, you are putting yourself in the most skilled and experienced hands. With over 5 decades of experience, our team of experts can address your unique problems with ease in Central Illinois. Whether it is high water tables or seasonal swings in the humidity or freeze-thaw cycles, we can manage effortlessly. Since we are a locally owned and veteran-run company founded in 1974, we know that crawlspace insulation must be dealt with in a holistic manner so that moisture is eliminated before thermal protection can work successfully. Our comprehensive inspections identify hidden issues like standing water, venting problems, and pest intrusion that must be resolved for insulation to deliver lasting results.

We have a variety of crawlspace insulation plans that can be adjusted to exactly fit your particular type, the weather conditions of the area, and your long-term performance requirements. In the case of vented crawl spaces, the conventional type whereby outside air is introduced in the conditioned crawl space via foundation vents, we normally insulate the floor joists above with either friction-fit fiberglass batts or closed-cell spray foam. It provides a thermal barrier between your conditioned living space and the unconditioned crawlspace beneath without freezing the plumbing lines or ductwork. To convert a crawlspace into conditional space, we use a modern approach that treats the crawlspace as part of your home’s interior. We start by insulating the foundation walls with rigid foam board or spray foam and installing a heavy-duty vapor barrier over the entire floor. Next, we create a clean and dry environment that protects against moisture and improves indoor air quality by preventing the stale effect, and provides additional storage space. With our free consultation, we offer an extensive examination of the particulars of your crawlspace, such as moisture, ventilation setup, access, and insulation, to suggest the proper course of action for long-term performance and viability. 

Frequently Asked Questions

Should I insulate my crawlspace walls or the floor above?

This all depends on whether it has a vented or sealed crawl space. In the case of vented crawlspaces, we insulate the floor above to allow separation between conditioned and unconditioned crawlspaces. Regarding sealed (conditioned) crawlspaces, we will insulate the foundation walls to get the crawlspace under the thermal envelope of your home. Your installation will be tested in the course of our free inspection, and the best strategy will be suggested.

It will all depend on your crawlspace venting or non-venting. In case of crawlspaces that are vented, we insulate the floor above to isolate the conditioned living space and the unconditioned crawlspace. In sealed (conditioned) crawlspaces, we insulate the foundation walls in order to make the crawlspace part of the thermal envelope of your home. We will test your installation as part of our free inspection and propose the best course of action.

Yes, dramatically. Insulating your crawlspace will provide a thermal barrier that will keep warm air in your home and will fail to bring in cold air from entering through your floors. Immediately after the installation, most homeowners experience a significant and immediate increase in the comfort of floors and lower heating expenses.

We deal with moisture in a holistic manner by first finding out the root cause of the moisture (be it grading problems, gutter problems, or foundation cracks) and then putting in proper vapor barriers, proper ventilation, or seals and, in some cases, even suggesting additional dehumidification. Our holistic design assures insulation has worked, and your crawlspace will be dry all year round.

Crawlspace insulation has a life span of decades when properly installed, and there is control of moisture. The foams are spray foam and rigid foam, permanent, and lifetime solutions. Provided the fiberglass batts are shielded against moisture using vapor barriers and are kept in dry surroundings, the batts can last forever. We are standing behind our work with quality installation, which gives it a long life.
