Trees and foundations
Big trees dry out clay. Cutting them down can cause its own problems. Here's what engineers say.
Coastal clay shrinks as it dries, and a large tree near the house can pull a lot of water from the soil under one side of a slab.
Two ways trees affect a foundation
Angi's August 2026 guide separates direct damage, where roots push against concrete, from indirect damage, where roots change the moisture in the soil around the foundation. It also notes that roots go looking for water, including at leaking pipes. Among the trees it names as higher risk because of shallow, fast-growing roots are oaks, ash, silver maples, sycamores and poplars.
Why cutting the tree down isn't automatically the fix
The Texas Section ASCE repair guidelines warn that removing a tree can cause upheaval as the soil takes back the moisture the tree was using, especially if the tree is older than the house. Engineers may recommend waiting for that heave before repairing. The guidelines describe regular pruning as a prudent alternative that may reduce further settling, though it may not bring the foundation back up.
Root barriers
The same guidelines note that root barriers can harm the tree, and recommend talking with an experienced arborist before installing one.
Planting new trees
Angi suggests at least 10 feet between a new tree and the house, and 25 to 50 feet for species with aggressive roots. Its list of slower-growing alternatives includes olive and English holly.
When a tree is part of the problem
- Tell the inspector about large trees near the house. The ASCE guidelines' most detailed investigation level includes a tree survey.
- Ask whether the repair plan accounts for the tree staying, being pruned or being removed.
- Check for plumbing leaks near the tree. Roots and leaks often go together.

Frequently asked
Should I cut down a tree that's near my foundation?
Not without advice. The Texas Section ASCE guidelines warn that removing a tree can cause soil heave, especially if the tree predates the house, and describe pruning as a prudent alternative.
How far from the house should I plant a tree?
Angi suggests at least 10 feet, and 25 to 50 feet for species with aggressive roots.
