Crawl Space Repair Solutions

If you have already identified that you have crawl space problems, a professional foundation repair company can help you implement the right crawl space repair solution to fit your needs. There are many crawl space repair solutions depending on the problem. Since the majority of crawl space problems result from moisture in the crawl space, a lot of solutions are designed to reduce, prevent or eliminate moisture from the crawl space either through proper drainage solutions or installing a moisture barrier.

Solutions for Crawl Space Moisture Problems

Moisture problems in your crawl space can be damaging to the structure and lead to mold, rot, and other issues. Luckily, there are several repair solutions that work to protect your crawl space from moisture. The most popular and effective among them are vapor barriers and encapsulation systems. Vapor barriers help control humidity levels by blocking the migration of water vapor between the soil surface and living areas; while encapsulation systems consist of a plastic film sealed to the walls and floors of the crawl space to create a barrier against pests, mold spores, radon gas, and moisture. Both solutions are designed to keep water out of the crawl space for long-lasting protection against damaging moisture build-up.

Crawl Space Encapsulation System

A crawl space encapsulation system is a full, moisture-protection system that includes adding a thick plastic (usually 12 mil to 20 mil), water-proof barrier to the floor of your crawl space. All of the seams are sealed and the liner is mechanically-fastened to the columns and walls to protect the entire space from water. The encapsulation system also usually includes sealing all vents from the outdoor air, insulating the walls, and installing a crawl space dehumidifier. All of these elements work together to protect the beams and joists under your home from becoming wet with condensation, which can lead to rotted wood.

A crawl space encapsulation system also improves the overall appearance of your crawl space. In addition, by removing the moisture and sealing up the vents, you will keep bugs and critters from making their way into your crawl space.

If you are looking for a less expensive option, then a vapor barrier might be the right solution for you.

Water Vapor Barrier

A vapor barrier also involves installing a thick plastic sheet on the floor under your crawl space. However, the plastic is not usually as thick (4 to 6 mil) as a crawl space encapsulation system and the seams of the plastic simply overlap each other. A vapor barrier is also not installed all the way to the top of walls and columns.

That being said, a vapor barrier offers many benefits. Vapor barriers stop not only water from entering your crawl space through the ground, but also it creates an air barrier that can improve the temperature in the crawl space. When the area beneath your home is warmer, your floors in the home above will also be warmer, saving you money on your energy bills.

Lastly, a vapor barrier can also help reduce harmful gasses such as radon from seeping into your home through the ground beneath the crawl space. A radon mitigation system is still recommended, but the vapor barrier does decrease the penetration of the gas.

There is a Waterproofing Option That is Right For You

There are several options for crawlspace repairs. You may need only one, or a combination of different methods to help solve the problem that you are having, and your contractor can customize the solution to your needs.

Crawlspace Waterproofing

Waterproofing a crawl space may seem like an intimidating task, but with the right components and knowledge, it can be done! Interior drainage systems capture the water and direct it to a sump pump where it is then removed from the crawl space. These pumps are equipped with alarms that will sound when the water level gets too high, alerting you to a potential problem. Dehumidifiers also help pull moisture from the air in the crawlspace to keep things dry and safe. With proper waterproofing efforts, your basement or crawl space can become a healthier environment that’s much less likely to cause costly damage over time.

Drainage Systems and Sump Pumps

Depending on the area of the country you live in, the earth beneath your home can be prone to shifting and moving when there is too much moisture in the soil. Interior drainage systems are designed to move water away from the base of the home. Sometimes these drainage systems are coupled with a sump pump, which is also designed to send water away from the residence.


High humidity can not only make you feel sticky and uncomfortable, it is also bad for your crawl space and home. When the humidity in your crawl space is high, condensation can start to form on your beams and joists, which can eventually lead to wood rot.

A crawl space dehumidifier improves the atmosphere beneath your home by pulling the air in, removing the moisture, and then pushing dry air back out in the crawl space.

Frequently Asked Questions About Crawl Space Repair Solutions

How much does it cost to remediate a crawl space?

Crawl space remediation, also known as crawl space encapsulation, can vary depending on the difficulty of accessing the crawl space, the size of the crawl space, and the type of encapsulation being used. 

The average encapsulation cost is around $6,000, but the cost can be as low as $1,500 or even go as high as $30,000. It’s always a good idea to get more than one bid from different professional foundation repair companies. Then make sure you are comparing apples to apples when looking at the bids. Are they using the same materials? Typically a polyethylene film is used, but they are not all the same thickness. Does the company offer a warranty on the product and/or their service? 

Figure out what suits your needs and your budget and be sure to check their reputation for service. My Foundation Repair contractors are thoroughly screened and must pass in-depth training before becoming a recommended expert.

Can you waterproof a crawl space yourself?

There are DIY solutions for waterproofing your crawl space, but they must be properly installed in order to prevent moisture from still forming in the crawlspace. Additionally, it can be very difficult to work in crawl spaces with low ceilings and little light. Be sure you understand what you are taking on before tackling this project on your own. It might be less expensive than you think to have a professional waterproof your crawl space for you. Additionally, most foundation repair companies offer free inspections/bids so it never hurts to reach out to a professional before you make your decision.

How much does it cost to repair a crawl space foundation?

The repair cost for a crawl space foundation depends greatly on what is wrong with the crawlspace, what is required to fix it, and what part of the country you live in. 

A crawl space foundation repair can cost as little as $2,000, but it could also be upwards of $30,000. On average, a crawl space repair is typically around $6,000, but it depends on what needs to be done. Small repairs such as replacing a support beam, replacing insulation, or repairing water damage may be less expensive, but they may also just mask the real problem. If the issue is related to the soil beneath the crawl space, more expensive repairs such as mudjacking, installing piers, or replacing underpinning which are required to level the house can be on the more expensive side.
