Waterproofing Crawl Space Cost: The Complete Guide

waterproofing crawl space cost

What should you do if your entire house has begun to smell musty and unpleasant?

Homeowners can avoid moisture concerns by designing and building smart crawl space foundations. Yet, most older homes didn’t have the right design elements in place when they were built.

This is when waterproofing your crawl space could be a viable option instead.

So, let’s dive into the waterproofing crawl space cost. Read on to determine how much you will have to spend to end your crawl space moisture issues permanently.

How Much Does Waterproofing Crawl Space Cost?

The cost of crawl space waterproofing ranges from $3,000 to $15,000, depending on the size of the crawl space and material used. If any repairs are required, such as crack repair or installing extra drains, pipes, and wires, plan to pay between $7,000 and $20,000.

If you’d like to encapsulate under your house entirely, the crawl space encapsulation cost is $3,000 to $8,000, or $3 to $7 per square foot, including installing a vapor barrier.

Is it Necessary to Use Crawl Space Waterproofing?

Yes, you should waterproof your crawl area to avoid the stack effect of a chimney and maintain your home’s structural integrity. Moisture from the ground might leak through the gaps in the floor and establish mold in your home if the crawl space is not dry and well ventilated.

Keep in mind that moisture can penetrate through concrete. As a result, it’s critical to either acquire a property that already has a watertight crawl area or address this issue as soon as you build your home.

We agree nobody spends a lot of time in the crawl space. Consequently, many individuals believe that waterproofing this space isn’t required. However, you’ll wind up spending more money fixing water damage than you would have spent waterproofing your crawl space.

Advantages of a Crawl Space

A crawl space is essential for lifting your home off the ground. It will keep moisture from infiltrating your home’s structure. A crawl space is even more beneficial to your home if you reside in a coastal sandy location where more water is present.

At the same time, it provides easy access to your plumbing, electrical wiring, heating, and cooling lines. If they need to be repaired, just enter the crawl area and replace the damaged system pieces without digging into the earth.

It is worth noting that waterproofing a crawl space is far less expensive than constructing a waterproof basement. In reality, the prices for a basement are ten times more.

Basement Waterproofing Cost

Basement waterproofing is one of those things that, if done correctly, can save you a lot of money in the long term. You can take several steps to reduce waterproofing costs so that you aren’t caught off guard later on. We recommend starting with a budget of $5-$10 per square foot and then padding it with research to price out choices.

From pricing the most exemplary sump pump for your basement to navigating any hidden charges that may arise, experts from us here at Sedona Waterproofing Solutions are ready to provide you with the basement waterproofing information you require.

Indoor Waterproofing

Here are some indoor waterproofing methods that may be used. These will help to prevent any existing damage from entering your home.

Cracks in the Hairline Foundation

Before you begin waterproofing, you must fix any hairline gaps in your foundation walls or basement floor by injecting epoxy into the fissures.

After injecting the epoxy, you must wait at least five hours for it to cure. It will prevent water from seeping through the gaps.

Epoxy injections might cost between $350 and $500 per crack.

Clearance of Flood Water

If your area is prone to flooding, water will most likely seep in through your basement walls and flood your basement or crawl space. Installing perimeter floor drains is an interior waterproofing method that regulates leakage in your basement.

This system diverts water away from your foundation, allowing your basement to remain dry. It will set you back anywhere between $2,500 and $10,000.

Basement Waterproofing Paint

Using waterproofing coatings to keep moisture at bay is a strategy that many contractors dislike. It is seen as a quick-fix option rather than a method of preventing water damage.

A gallon of weatherproof paint should cost roughly $30 and cover 75 to 125 square feet.

Outdoor Waterproofing

If you live in a flood-prone area or have poor soil conditions, we recommend that you investigate these outdoor waterproofing options as well to keep your basement and foundation secure.

Water Damage to Interior Walls

Excavation is used when your contractors cannot reach the damage to your basement walls from the inside.

Once done, excavation will allow you to waterproof walls or parts of them. This might wind up costing between $100 and $200 per linear foot, depending on how deep your contractors have to dig and how accessible the damaged portions are.

Water Seepage and External Leakage

If the soil around your foundation is damp, seepage via gaps between the soil and the foundation may occur. One of the most successful waterproofing solutions for preventing such seepage is to fill the space with sodium bentonite.

Sodium bentonite costs $500 a ton and is a clay-like material that expands and fills holes when it comes into contact with water, essentially blocking any water from entering.

Outside Flood Water Clearance

Exterior French drains are a simple yet efficient technique to prevent water from entering your basement, especially during floods. Installing these drainage systems will cost you between $1,000 and $4,000, which is far less than its indoor counterpart.
