Tree Roots vs Your Home: When Removal Is the Answer

If you’ve noticed cracks in paths, lifting pavers, slow drains or a leaning fence, you might be dealing with tree root damage to house structures. Roots don’t set out to break things— they chase moisture and oxygen. But around slabs, plumbing and retaining walls, that search can create costly issues. Knowing when to prune, and when to remove trees near house foundations, protects your property and peace of mind.

Common damage

Roots often show their hand in the easiest places to disturb: cracked driveways, uneven paths and raised garden edging. Over time, pressure from growing roots can shift lightweight slabs and stress brickwork. Inside, doors may stick and small gaps can appear along cornices where movement has occurred.

Tree roots and pipes are another frequent problem. Fine feeder roots enter tiny pipe defects and expand, causing blockages and backups. In heavy rain, compromised stormwater lines can overflow and undermine soil around footings. Left unchecked, that adds to foundation risk, especially on reactive clay soils where moisture swings make movement worse.

Assessment

Before any pruning or removal, start with a clear picture. Walk the site and note symptoms: cracks, pooling water, sinking soil, repeated drain blockages, or a tree noticeably closer to the house than you’d expect for its size. Map services if you can—knowing where sewer and stormwater run helps connect the dots.

Next, engage a qualified arborist. A professional assessment weighs species behaviour, root architecture, soil conditions and the proximity to structures. If plumbing issues are suspected, a licensed plumber can CCTV-scope lines to confirm root ingress. Depending on your council area, approval may be needed for removal of certain trees; an arborist can guide you through what applies locally.

Removal vs root pruning

Root pruning can be appropriate when:

• The tree is healthy, structurally sound and suitably sized for the site.

• Intrusive roots are limited and away from critical support zones.

• There’s safe access to install a root barrier after pruning.

However, root pruning has limits. Cutting major structural roots can destabilise the tree and increase failure risk in storms. If the problem roots are within the anchor zone (typically within a radius of a few metres of the trunk, depending on species and size), pruning may compromise safety.

Removal is often the responsible choice when:

• The tree is oversized for the block and sits too close to footings, creating ongoing foundation risk.

• There’s recurrent damage to hardscapes or repeated root intrusion into pipes, even after repairs.

• The species is known for aggressive rooting or high water demand near buildings.

• The tree shows structural defects (decay, poor unions, significant lean) that increase risk.

In these cases, fully remove trees near house structures rather than repeatedly treating symptoms. It’s usually safer, clearer for insurance conversations, and more economical over time.

Aftercare

If removal is recommended, comprehensive aftercare prevents a repeat performance:

• Stump grinding: Grind the stump and large surface roots to an appropriate depth to prevent regrowth and allow for reinstatement of soil, paving or turf.

• Pipe repairs: After addressing tree roots and pipes, consider relining or replacing damaged sections to stop future ingress.

• Root barriers: Where practical, install physical root barriers between garden beds and structures. These guide future roots downward and away from slabs and services.

• Drainage tune-up: Keep gutters, downpipes and stormwater lines clear. Good drainage reduces the moisture gradients that attract roots towards foundations.

• Smart replanting: Choose moderate-sized, non-invasive species and plant well away from buildings and services. As a rule of thumb, plant at a distance at least equal to the tree’s expected mature height—more if space allows.
