What should I do about tree roots near a foundation?
Do not assume that roots near a foundation caused a crack or that cutting them will solve it. Record the tree, the building symptoms and any changes in water or ground conditions separately. A building or foundation professional can evaluate the structure, while an arborist evaluates the tree and the consequences of proposed root work. Those assessments answer different questions and may need to be coordinated.
Avoid digging beside the foundation, cutting roots or changing the ground level as a first response. Root injury and altered growing conditions can affect the tree, and a building symptom may have causes unrelated to it. Ask for an explanation of the evidence linking any proposed work to the actual problem before authorizing tree removal as a foundation repair.
Safety boundaryKeep clear if there is new tree instability, falling wood or apparent building danger. Do not enter a suspect area to expose roots or inspect beneath the structure.

What changes by state, city and property?
The national answer stays the same, while these local or property variables can change the next step: Foundation type and documented symptoms; Tree species and root-zone conditions; Drainage, soil history and proposed excavation.

Separate immediate hazards, tree condition and property constraints
Which situation best matches the property?
01
Roots are visible, but no building damage is documented
A nearby root is an observation, not proof of foundation damage. Start by defining the concern: a root at the surface, insufficient planting space or a proposed construction conflict. The arborist can assess the tree’s growing space and the consequences of altering roots. A decision to remove a healthy tree should not be based solely on an unsupported claim that every nearby root is destructive.
Notice next: Photograph the relationship from the surface and gather existing plans. Ask whether any actual building evaluation is indicated before choosing root or tree work.
02
Cracks, moisture or other building changes are present
Give the building professional the symptom history, including drainage and recent site work, without presenting the tree as an established cause. Water management around a foundation can be relevant to moisture problems, while structural questions need their own evaluation. Have the arborist’s findings supplied as context rather than used to replace the building assessment.
Notice next: Record where and when the symptoms appeared. Ask what evidence would distinguish a tree-related issue from other site or building causes.
03
A contractor proposes cutting roots or removing the tree
Ask exactly which part of the diagnosed problem the proposal is expected to address. Root cutting can affect a retained tree’s condition and stability, so the arborist should understand the proposed location and extent. A tree-removal scope should not quietly become a promise to stabilize a foundation. Obtain separate responsibility for the building diagnosis, tree work and any restoration.
Notice next: Request a coordinated written explanation before non-emergency work. Resolve utilities, access and relevant permissions for any excavation rather than treating roots as the only buried concern.
Safe observation
What to record before contacting a professional
Use only safe, non-destructive observations and existing records. Do not create access or disturb a hazard to complete this list.
These observations organize a conversation; they do not diagnose the property or prove service availability.
What to record
Keep dated photographs of visible roots and the building exterior taken from normal safe access points.
Record the location and history of cracks or moisture without scraping, drilling or opening concealed areas.
Collect prior foundation reports, tree work records and drainage or excavation plans.
Note changes in downspouts, irrigation, paving or ground level and whether they preceded the concern.
Stop and get appropriate help
Stop root cutting or excavation until the impact on the retained tree and the building has been evaluated.
Use urgent professional or emergency attention when movement creates an immediate danger rather than continuing a routine tree discussion.
Move from information to action
Who is the useful next contact?
Structural or foundation professional
Use this professional for building movement, structural adequacy or a proposed foundation repair. A tree contractor is not a substitute for that assessment.
What evidence connects the roots to the specific building symptom?
What other causes were considered?
How would the proposed root work affect the tree that remains?
Which professional is responsible for each diagnosis and repair scope?
Arborist
Use an arborist to interpret tree condition, growing space and the effect of proposed root cutting or removal. Ask for coordination with the building evaluation when the scopes interact.

Which professional is responsible for each diagnosis and repair scope?
Drainage professional
Use drainage expertise when water routing is part of the reported problem. Clarify whether the issue is surface water, another moisture source or an unresolved structural concern.

Short answers
Questions people ask before the call
Should I remove the tree before the foundation inspection?
Not merely because it is nearby. Establish the building problem and the tree implications first, unless an immediate tree hazard requires a separate urgent response.
Can I cut only the root touching the house?
Do not decide from contact alone. Root work needs tree-specific assessment, and cutting may not address the cause of a building symptom.
Does fixing drainage prove the foundation is sound?
No. Water management and structural assessment are different questions. Ask the responsible professional which issue has been resolved and which still needs investigation.
