Crawl Space Insulation
Crawl space insulation reduces temperature fluctuations in the conditioned part of your property. It also serves as a way to help prevent structural (foundational) damage, keep pests away from your crawl space, and prevent water and moisture (see the full list of benefits below). Our crawl space insulation services extend to both residential and commercial clients.
If you live in the St. Louis area and need to replace your insulation, then Gonz Insulation is the name to call. As locals to eastern Missouri, we value assisting the local residents, who we call our neighbors. We ensure a safe and successful insulation process for your home’s crawl space.
Commercial projects are usually much larger in scope than residential, and there may be certain regulations and requirements that commercial properties have that homes do not. With an experienced and dedicated team of insulation professionals and all of the resources necessary, we can complete commercial crawl space insulation pr a timely manner and according to the specific requirements that are applicable to your organization.
The Benefits of Crawl Space Insulation
There are many benefits of crawl space insulation for your home or commercial property. The most notable benefits include improved energy efficiency, the prevention of water and moisture damage, improved structural integrity, and the prevention of pests inside your crawl space.

Risks of an Uninsulated Crawl Space in St. Louis, MO
Saint Louis (as well as the rest of Missouri) endures cold winters. If your crawl space is not properly insulated, then you are more vulnerable to a host of issues with your property. Notably, the risk of your plumbing freezing during the winter months is much greater without proper insulation. This could lead to the need for expensive repairs and time when your plumbing system is out of service.
Additionally, you may experience higher monthly heating and cooling costs without a well-insulated crawl space as well, especially during cold winter months and warm summer months. Your crawl space could also develop water damage without reliable insulation, which can compromise the structural integrity of your property’s foundation.

When Crawl Space Insulation is Necessary
We recommend replacing your existing insulation every 15 to 20 years if you have fiberglass or cellulose insulation. Of course, new insulation is strongly recommended for new construction properties as well. The best way to determine the exact time to replace your crawl space insulation is to schedule regular inspections every two to three years. You may also need new insulation if you have noticed substantial increases in your heating and cooling costs, have found signs of pests in your crawl space, have noticed signs of water damage, or have experienced compromised air quality and comfort inside your property’s conditioned space.

Frequently Asked Questions About Insulation for Crawl Spaces
The more information you have the better decisions you are able to make as the property owner or manager. Below are answers to common questions we receive about insulating crawl spaces. Of course, you can also call us at any time for more specific information.
This depends on a variety of factors, including whether or not your crawl space is open or vented and your initial budget. In general, spray foam is the best quality and overall value you can purchase for crawl space insulation. However, in some cases, fiberglass or cellulose insulation may be good choices as well. The best way to decide is to simply call our professional team and discuss all options.
Vapor barriers are a great way to control condensation and moisture in your crawl space. However, you still need reliable insulation to ensure optimal temperature control in the conditioned space of your home or commercial property.
Installing your own insulation is strongly discouraged as it can be a dangerous job. It is also complex and improperly installed insulation can be as good as no insulation at all. Additionally, spray foam materials involve the use of chemicals during installation, which can make the job even more dangerous without the proper safety equipment. You also must dispose of waste and removed insulation properly as there may be laws and regulations that apply. On the other hand, professional installation with Gonz Insulation ensures the job is done safely and correctly.
Diagnosing a need for crawl space insulation can be a challenge for homeowners. This is especially the case if your crawl space is dangerous or hard to access. Gonz Insulation offers free inspections and energy audits to determine if (and to what extent) you need crawl space insulation. Our energy audit also includes an assessment of your attic and other vulnerable areas of your property where insulation is necessary.
You may not need to remove your subfloor insulation if it is in good condition. However, in many cases, the subfloor insulation is damaged, wet, or moldy and must be removed and replaced. Our team is able to properly remove existing insulation once it is outdated or damaged and replace it with a higher-quality material.
