Trees Growing Too Close to Your Foundation
in Columbus, GA
Homes in Columbus built between 1950 and 1980 frequently have large trees planted within ten feet of the foundation. At the time, those trees were small. Now they are mature, and their roots follow moisture straight to the foundation perimeter. The heavy clay soil here shrinks and swells with rain, which shifts the foundation independently of the roots, but roots that are already there make that movement worse. Cracks in brick veneer or interior floors can follow.
Quick Answer
Tree roots grow toward water, and the moisture that collects along a foundation is exactly what they are looking for. In Columbus, where homes built in the 1960s and 1970s often have large trees planted close to the house, roots have had decades to work under and around the slab or footings. Removing the tree or pruning the roots away from the foundation stops the problem from getting worse. Waiting lets the roots get larger and the repair bill along with them.
Telltale Signs
Warning Signs to Watch For
- Cracks in the brick or mortar on the side of the house nearest a large tree
- Doors or windows sticking on one side of the house only
- Visible roots running along the soil surface toward the foundation edge
- Cracks in the interior floor slab nearest to a large tree
- Gaps opening between the foundation and the bottom of the siding
Root Causes
What Causes Trees Growing Too Close to Your Foundation?
Root growth under foundation perimeter
Tree roots in Columbus's clay soil follow the moisture gradient that builds up along the outside of a foundation. Once roots get under the footing, they grow thicker each year and put upward pressure on the slab or stem wall.
The Fix
Root Pruning and Tree Relocation
We cut the roots at a safe distance from the trunk and install a physical barrier to redirect future growth. If the tree is too large and too close, removal may be the only option that stops the root pressure for good.
Soil drying under foundation from tree water uptake
Large trees pull significant water from the soil around them. In dry summers, a big oak near a Columbus house can dry out the clay soil under one side of the foundation. That causes the clay to shrink, and the foundation settles unevenly.
The Fix
Tree Removal or Root Barrier Installation
Removing the tree or cutting its root access to the foundation zone lets the soil moisture stabilize over time. A structural engineer may also need to look at the foundation itself to see how much movement has already happened.

| Doors sticking or not closing on the same side of the house as a large tree | ||
| Visible roots running along the soil surface toward the foundation | ||
| Cracks appearing or getting worse in dry summers then partially closing in wet weather | ||
