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.

Small gaps can signal bigger issues

Gaps that weren't there before? Don't ignore them.

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.

Gap between bathroom window frame and brick wall

Why are gaps forming around openings?

Foundation movement changes the shape of your home. Literally.

Subsidence or uneven settlement
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
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
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 near a home
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.

Stopping the movement, protecting your home long-term

We fix the cause, not just the gaps

Filling or re-caulking gaps won't help if the structure is still moving. Nor will all foundation repair methods deliver a permanent solution. Our process addresses the underlying issue:

  1. Start with a professional Home Check-up to assess if the gaps are cosmetic or structural.
  2. If structural movement is confirmed, we arrange a forensic engineering report to determine the cause and required fix.
  3. Our team designs and installs screw pile underpinning to stabilise your foundation and, where appropriate, lift it back into alignment.
  4. 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.
