Foundation Leaks: What To Look For and What To Do
Updated: Mar 12
When you’re looking to put your home on the market, the last thing you want to deal with is a leaking foundation. A cracked foundation isn’t going to make your home impossible to sell, though. If you suspect you have a leak in the property you’re preparing to sell, you can either let it be and list your home as-is, or you can have it treated.
How do you know, though, when your foundation is leaking, and what solutions do you have available to you?
The Causes Behind Foundation Damage
You might think that a foundation crack appears abruptly. While this can sometimes be the case, especially if your area is prone to natural disasters, it’s rarely the primary cause. Instead, foundations tend to crack when exposed to stress in the long-term.
Common causes of a foundation crack include but are not limited to:
Heavy rain: The more it rains in your area, the more water your soil is going to have to absorb. Unless you’ve thoroughly waterproofed your foundation, the pressure that builds up from the water around your home – known as hydrostatic pressure – will stress your foundation to the point of cracking.
Shifting soil: The soil particles around your home grow and shrink in response to the weather. If you’ve gone without rain for a long time or aren’t able to water your lawn, then your soil will shrink, and the landscape around your home will start to shift. You won’t visibly notice this shift, but your foundation with shift with the moving particles to accommodate for the change.
The weather and your foundation: If the weather is below freezing one day and above it the next, your foundation is going to contract and expand. Rapid contractions and expansions can occur when the weather rapidly changes, and they will cause your foundation to crack. (Sound familiar, Virginia Beach homeowners?)
Your foundation’s construction: Sometimes, the contractor who originally built your home may not have taken the area’s precipitation history or other details into account. As a result, your foundation may be made out of inappropriate materials for your surroundings or may simply not be up to modern-day code.
Your landscaping: The trees and bushes you plant around your home need to have smaller root systems than the ones you plant further out in your yard. If a tree’s root system starts trying to grow through your foundation, it’ll crack through the concrete or brick.
What to Look for When Your Foundation Leaks
Basement leaks and foundation leaks in the crawl space often look similar at first. However, there are some symptoms that are distinct to foundation leaks that you’ll be able to keep an eye out for. If you’ve treated your basement for a leak and are still dealing with frequent flooding, look for the following that may indicate a more serious crack:
Gaps at the joints of your foundation
Water-damaged belongings or furniture
Sometimes, when the leak in your foundation is severe, you’ll be able to spot symptoms from the outside of your home. These symptoms might include but are not limited to:
Vertical cracks in your walls
A cracked chimney
Cracks running horizontally across your foundation
Signs of sinking
The symptoms that signal a leaking foundation tend to get worse over time, so be sure to reach out to a contractor for a free inspection if you spot more than one. Note, too, that if you live in an area that’s prone to natural disasters, you may see a foundation crack appear and grow within a few days of that disaster occurring.
Fixing a Leaking Foundation
Selling a home with a leaking foundation can be a challenge, but it isn’t impossible. If a contractor finds a leak in your foundation, you can either list your home as-is or have the contractor offer solutions. Some of the simplest foundation repair solutions include:
Leveling and slabjacking
Note that these services can cost anywhere from $500 to $6,000. However, you may find that they’re worth the expense. When you list a home that has an untreated foundation crack, you risk losing up to 30 percent of your home’s market value.
