A crawl space foundation is installed in about 15% of new single-family homes, according to the Survey of Construction. 54% of homes have a slab foundation, which shows that it is still the most common choice. Architects and builders may still suggest a crawl space foundation for several reasons. Let’s look at crawl space foundation repairs and the difference between a slab vs. a crawl space foundation and cost in this post. Let’s get this party started!

Crawl spaces are so-called because they are only accessible by crawling; with only about 18 inches of clearance, they are not large enough to be used as livable spaces. As a result, they may appear to be a poor compromise between a full basement and a concrete slab foundation. However, they combine many of the advantages of both—in addition to providing a solid, durable foundation for your home, they also provide space to store plumbing systems and the electric panel.

What is a Crawl Space Foundation?

A crawl space foundation consists of concrete walls and a floor. The walls are at least 18 inches above ground level, and this area will be accessible after the house is built. This is usually where the plumbing is installed.
Crawl space foundations have a flat concrete slab but are built up with concrete walls, sometimes wooden walls, and footers. They have enough space for someone to crawl through to fix problems beneath the surface.

Crawl Space Foundation Repairs

When it comes to home repairs, the basement foundation seems to get all the attention, while the crawl space is the forgotten stepchild. Crawl space foundations, on the other hand, are just as important as basement foundations. Furthermore, because they go unnoticed, it is critical to keep your crawl space strong and safe.

Preparing for Crawl Space Foundation Repairs

Fortunately, you won’t have to do much before the crawl space foundation repairs begin. There are only two critical steps. The first step is to arrange for a crawl space foundation repairs inspection. Although you may be tempted to repair the damage yourself, repairing the crawl space should never be attempted as a do-it-yourself project. It is best to talk to experts who know how to look at the damage and figure out what caused it.

The second thing you’ll need to do is clear out the crawl space foundation to ensure efficient repairs. Many homeowners use this space as a tool shed, which is not advised. Some people even use it as a secondary pantry, which is a bad idea because easy access to food attracts rodents and other pests. If you use your crawl space for storage, you must remove all of your belongings so that installers can begin their work.

Fixing the Crawl Space Foundation

If you’re wondering how long the repair process will take, it will mostly depend on the type of damage you’re dealing with. For example, if your foundation has been damaged, excavation may be required. However, if moisture has damaged the support beams in the interior of your crawl space, you may not need to dig. Some things are universal to all repairs, regardless of what your installers need to do.

#1. The priority is structural repairs.

What is more important, your house’s stability or its appearance? When it comes to repairs, experts will always put tasks that keep your home’s structure stable at the top of the list. Don’t be concerned if your house looks more like a construction site than a home for a few days. After the installers have made sure that your home is stable and safe, they can move on to the finishing touches. Your house will be in much better shape after they leave than it was when they arrived.

#2. There are no all-encompassing solutions.

Experts advise against doing it yourself because the crawl space area can be difficult to repair. There may be problems that come up out of the blue, and there will likely be more than one problem that needs a mix of solutions. Only experienced professionals can recommend long-term solutions that are best for your situation, so do not attempt to repair the damage yourself.

#3. Encapsulation is advised.

If you haven’t sealed off the foundation of your crawl space, your installers will probably tell you to waterproof this area. This is a wise investment because water damage can cause a wide range of issues and have a serious impact on the health of your home. Putting up a vapor barrier will protect your home from water damage and stop the problems you’re having now from happening again.

What Happens After Crawl Space Foundation Repairs?

There aren’t many things you need to do after your crawl space has been repaired by a team of professionals. They’ll clean as they go, and your house will look even better than before. If you took personal items out of the crawl space before the crew got there, you will need to replace them or find a new place for them, especially if you encapsulated the space. In rare cases, you may need to check the repair solution after some time has passed, but the repair team will thoroughly explain what you must do.

After experts repair your crawl space, all you have to do is take good care of your home and schedule annual maintenance appointments for your waterproofing solutions. This way, you’ll avoid problems you could have avoided, catch warning signs early, and make sure the structure of your home stays strong for years to come.

Cost of Crawl Space Foundation Repairs

Sinking or settling in a crawl space foundation can cost $2,000 to $8,000 or more to repair. When a foundation is damaged, it may need new piers or underpinning to make it stronger or raise it, cracks may need to be fixed, or the house may need to be brought back to its original level by mudjacking or another method.

Crawl Space Foundation Cost

Due to differences in size, complexity, and features, the cost of installing a crawl space foundation can range from $8,400 to $26,500. The average cost is approximately $15,350, or $13.65 per square foot. The crawl space cost includes all of the materials and labor needed for a concrete or block foundation contractor to build and finish a crawlspace.

The installation of a crawlspace is straightforward. The crawlspace parameters are marked, and soil is removed to at least 30″ depth unless the ground is sloping and will remain bare. The walls are either framed and poured, or they are marked and built with cinder blocks. Footings are required for both types. Although a slab floor is optional, most crawls include one when possible. As with concrete driveways, you have the option of a 4″ or 6″ slab.

Slab vs. Crawl Space Foundation

A slab foundation is a raised slab on which the house is built. A crawl space foundation, on the other hand, has concrete walls on the outside and sometimes support walls on the inside. These walls raise the house 18 inches or more above the ground, giving plumbers and electricians a place to work under the house.

Things to Consider: Slab Foundation Vs Crawl Space

There are several factors to consider when deciding whether to build a slab foundation vs. a crawl space foundation.

#1. Winters

Winter can be extremely damaging to your home. When building, it is critical to consider what the winters are like. Slab foundations can crack if temperatures are too low, but they also heat up faster. Either will work as long as the building is ready for winter and the right amount of concrete is poured.

#2. Moisture level

Moisture can also wreak havoc on foundations. As a result, ensure that your team takes this into account as well. When moisture seeps through, a slab foundation can be slick, but it is far superior to a crawl space foundation in this regard.

#3. Energy-efficiency

You can put heat lamps and other similar devices under crawl space foundations, but slab foundations are better if this is your main concern. Because of the crawl space, more air can pass through the bottom.
Air and moisture barriers can help with this, so if you do get a crawl space foundation, make sure to install one. In many cases, this can also serve as an air barrier.

#4. Price

Let’s face it: Cost is always an issue. Crawlspace foundations are considered high-end, but they are significantly more expensive than slab foundations. This is because you are paying for the slab and then some.
Some contractors are aware of this and will not charge much more for the crawlspace if they believe it is necessary. So discuss the price differences with them ahead of time. You might only have to pay for the additional materials.

#5. Maintenance

Crawl spaces require far more upkeep than slab foundations. but that’s because they’re more than that. Crawlspaces should be checked once every month or two to ensure everything is in working order. You can usually hire someone to come out and inspect things regularly. They usually give you a discount if you pay for them to check in ahead of time.

#6. Ground levels 

Crawl spaces are ideal for uneven terrain. This is because they can be built on a hill, whereas slab foundations cannot unless the hill is not very steep. It is best to construct a crawlspace or basement for hills.
