Walls leaning in your basement? Here's your guide to figuring out what needs to be done.

What Causes Leaning Walls in Basements?

Hydrostatic pressure

You may be surprised to hear, but your leaning basement wall may actually be caused by unresolved water issues in and around your basement.

Basically hydrostatic pressure (water) can build up surrounding your house. When this happens, it puts weight (or pressure) on your basement walls.

This is not always the case.

Poor build

The issue could also be poor construction or simply signs of an aged house.


If you live in the northern U.S., you're not unfamiliar with freezing temperatures. This can cause the soil to expand and put more pressure on the walls.

Whatever the case, when pressure builds up on the walls, they have no where left except to lean or bow or buckle.

Can Leaning Basement Wall Be Fixed?

Good news

The good news is that in many cases the answer is yes.

Like most basement repair issues, each case needs to be examined by an expert. But fixes are absolutely doable in many cases.

Bad news

The bad news is that it's not always an easy fix. It can require heavy equipment and/or materials.

There are some products on the market which now allow us to be able to fix this issue without needing to excavate, but again, it depends on your particular situation and how significant the walls are leaning.

How Much Basement Wall Leaning is Acceptable?

It's never a pretty sight to see your wall starting to lean.

Our recommendation is to get it checked out by a professional whenever you see cracking or bending, even just as a precaution.

Leaning walls do not correct themselves.

The thinner your wall is, the less bowing it can handle. There are some general percentage rules of thumb for how far a wall will be able to lean before serious damage occurs.

But in reality, it's best to get them checked out by professionals.
