Gaps Around Doors and Windows? Your Foundation Might Be Moving
Visible gaps or separations can be a sign that your home’s structure is shifting due to subsidence or uneven settlement.

Gaps That Weren’t There Before? Don’t Ignore Them.
Small gaps can signal bigger issues.
If you’ve noticed widening gaps between window frames and brickwork, or daylight sneaking through around your doors, you’re not alone. These gaps often develop gradually and are easy to dismiss—but they can be early indicators of foundation movement.
At Foundation Solutions, we specialise in identifying whether these signs are cosmetic or structural. And if your home is moving, we use engineered screw pile underpinning to stabilise it permanently—so those gaps don’t get worse.

Why Are Gaps Forming Around Openings?
Foundation movement changes the shape of your home—literally.

Subsidence or Uneven Settlement
When parts of your foundation sink at different rates, it causes the structure above to twist or distort. The result? Gaps where doors and windows were once flush.

Soil Shrinkage or Expansion
Reactive soils under your slab expand when wet and shrink when dry. These constant shifts put pressure on your frame, often pulling door and window openings out of square.

Water Damage or Drainage Issues
Excess moisture from poor drainage or leaking pipes can erode supporting soil, undermining the foundation and creating uneven load distribution—leading to structural gaps.

Tree Root Activity
Large trees near your home can pull moisture from the soil, causing shrinkage and settlement beneath your foundation. This subtle shift over time creates widening gaps around openings.
We Fix the Cause
— Not Just the Gaps
Our structural approach stops the movement and protects your home long-term.
Filling or re-caulking gaps won’t help if the structure is still moving. Nor will all foundation repair methods deliver a permanent solution to your foundation problems. Our process addresses the underlying issue:
- Start with a professional Home Checkup to assess if the gaps are cosmetic or structural.
- If structural movement is confirmed, we arrange a forensic engineering report to determine the cause and required fix.
- Our team designs and installs screw pile underpinning to stabilise your foundation, and where appropriate, lift it back into alignment.
- Once your home is stable, any cosmetic repairs will last—as they’re no longer fighting against ongoing movement.
If you’ve noticed gaps forming around doors and windows, let’s find out what’s causing them—and how to make them stop.
