Crawl Space Cleaning – Why You Need to Get Rid of Moisture in Your Crawl Space

Crawl Space Cleaning

Moisture that is left unchecked in crawl spaces can lead to serious structural problems. It eats away at wood beams and can cause mold issues as well as invite unwanted guests like pests and rodents.

Cleaning your crawl space can help with odor removal, insulating the area and repairing any damaged areas. It can also prevent pests and termites from infesting your home. Contact Crawl Space Cleaning Los Angeles for professional help.

While some moisture in your crawl space is inevitable, if water accumulates and there’s no way for it to escape, you have a serious problem. Standing water can lead to mold growth, mildew, and wood rot that compromise the structural integrity of your home. Moisture also contaminates the air in your living spaces, contributing to a variety of health issues and making it more difficult to maintain an even temperature throughout your home.

Mold spores and mildew circulating in your air creates a musty smell that can be difficult to get rid of. These spores can also trigger asthma and other respiratory ailments in people with sensitive allergies. Having damp air in your home can also make it more expensive to heat and cool, since moisture resists temperature change.

If water damage has occurred in your crawl space, a professional should be called to clean up the mess and restore any damaged insulation. Professional restoration companies know how to work with contaminated water and are used to dealing with tight spaces. They are also able to spot structural problems that can be overlooked in the rush to get the water out.

The first step in tackling crawl space water damage is to locate the source of the leak and determine how severe the issue is. This can be a challenging task as some crawl spaces are hard to access and may require removing or breaking through insulation to get at the cause. Once the source of the water is identified, a plan can be implemented to prevent future issues.

One option is to install a crawl space sump pump with a French drain. This will help ensure that any future flooding won’t cause major problems for your home. Another solution is to install a vapor barrier and use a dehumidifier in your crawl space to keep it dry.

Another option is to fix the grading around your foundation so that rainwater and snow melt doesn’t pool near your house’s foundation and seep into the crawl space. Lastly, installing a gutter system that directs rainwater away from your foundation can also help prevent crawl space flooding.

Mold and Mildew

Mold and mildew grow in crawl spaces due to a combination of factors, including flooding, plumbing leaks, poor ventilation, and drainage issues. Once mold starts to form, it can spread quickly and cause damage to the wooden structure of your crawl space. The mold spores can then travel throughout the home, impacting indoor air quality. This can cause allergy and asthma symptoms in those prone to these conditions.

Mildew and mold in the crawl space also affects the insulation, reducing its effectiveness. This can lead to an increase in utility bills. If you notice a musty smell in your crawl space, you likely have high levels of humidity. This is caused by the warm air in your crawl space interacting with untreated wood, which encourages mold and rot. A crawl space cleaning specialist can address the source of the issue and install a plastic vapor barrier to protect your crawl space and home.

You may be tempted to try a DIY mold remediation project, but this is a job best left to the professionals. It requires the use of power tools, a dehumidifier, and proper safety equipment. It’s also a good idea to have your crawl space inspected on a regular basis by a professional.

Addressing the causes of moisture in your crawl space will prevent mold, mildew, and wood rot. This includes fixing plumbing leaks, ensuring the ground slopes away from your crawl space foundation, and waterproofing your crawl space floor. A crawl space cleaning professional can help you with these projects and provide a variety of other preventative solutions, such as a plastic vapor barrier or encapsulation system.

A crawl space that is clean and dry provides many benefits to homeowners, especially those with respiratory problems. A sanitized crawl space can significantly improve the air quality in your living spaces, as well as reduce energy costs.

If you’re thinking of selling your home, a clean crawl space can be a major benefit during the home inspection process. Often, potential buyers are hesitant to purchase a home that has a history of moisture and mold in the crawl space. By addressing these issues before you sell, you can avoid the stress of having to disclose them during the home sale process.

Pests and Insects

If you’re not regularly going beneath your home to check on things, it can be easy for rodents and other pests to move into your crawl space. Rodents and insects are drawn to crawl spaces because of the damp, dark environment. They can cause serious problems by destroying or chewing wires, contaminating surfaces and spreading disease. In addition, their droppings can contaminate your home, causing respiratory problems for your family members.

Cockroaches, rats, mice, ants and spiders can all be found in crawl spaces, and some of them are dangerous. The best way to prevent pest infestation is to keep your crawl space clean of any debris, weeds or rock piles that could attract them. Then, make sure that the area is properly ventilated to keep the air dry.

In addition, it’s important to seal any holes or cracks that you see in the crawl space. The smallest openings can serve as entryways for pests, and you can fill them with caulk or spray foam insulation. Spray foam is a better choice because it can expand to fill even the smallest gaps, while caulk is limited to narrow cracks.

You can also help fend off pests by keeping your yard well maintained and trimming nearby bushes. Many invasive bugs are attracted to certain types of foliage, and they can hide in the branches and leaves of these plants before making their way into your crawl space.

Getting rid of pests in the crawl space can be a difficult and costly task, so it’s best to take measures to prevent them from moving in in the first place. Practicing good hygiene, cleaning frequently and storing food properly can be effective ways to deter pests.

In the event that your crawl space does get infested with pests, it’s important to contact a professional. They can use long-lasting insecticides like Supreme IT to control termites, cockroaches and other pests, as well as rodent-specific products to eliminate rats, mice and squirrels. Rodents and other pests can carry diseases that can spread to your family, so it’s important to have them eliminated as quickly as possible.


Termites are one of the most destructive pests that can plague a crawl space. They are known to cause millions of dollars worth of damage each year to homes across America. In fact, homeowners spend an average of $3,000 to repair the damage caused by these tiny insects. Termites are attracted to wood and cellulose and they can destroy the structural supports that hold up your house. A crawl space with moisture is an ideal environment for termites to thrive in. Regular crawl space cleaning can help prevent moisture and keep these pests away.

Crawl space cleaning can also reveal termite infestations before they become a major problem. Termites can cause significant damage to your home, including foundation cracks, wood rot and wood damage to support beams. Termite colonies often start in the soil around your house and move upwards through a series of tunnels that lead into the wood members of your home. Look for signs of a termite problem in your crawl space, such as piles of small pellets (called frass) or discarded wings, which may be light tan to dark brown in color. If you hear wood-chewing noises in your crawl space, you have a termite infestation and it is time to call for pest control.

You can reduce the chances of a termite infestation by keeping wood products away from your crawl space, as well as any debris or firewood that is stored in or near your home. Store wood and paper products several feet away from your home and avoid storing them under decks or in the ground. If you have a firewood pile near your house, keep it several feet away from your crawl space and on a raised platform.
