Foundation Problems Specialists Quote For

The cause decides the repair, so describe what you see and how long it has been happening when you request quotes.

How Foundation Repairs Work

1. Look at the damage. A specialist checks crack patterns, floor levels, doors, windows, drainage and the ground around the house, from photos first or on site.
2. Find the cause. Where the movement is structural, a structural engineer investigates. This can include crack monitoring, test pits or a geotechnical investigation.
3. Specify the repair. The engineer or specialist sets out what needs to be done, such as drainage, underpinning, piling or crack stitching.
4. Compare quotes. Contractors quote on the same scope so the prices can be compared.
5. Repair and reinstate. Support is installed, cracks are repaired and finishes are made good, with sign-off where an engineer designed the work.

Ask each specialist who will design the repair and who signs it off.

Common Causes of Foundation Movement

• Expansive clay. Swells when wet and shrinks when dry, lifting and dropping foundations with the seasons.
• Collapsible or loose soils. Settle when they get wet or were poorly compacted under the building.
• Water. Leaking pipes, blocked gutters and stormwater pooling against the walls soften the ground.
• Trees. Roots draw moisture from clay close to the house.
• Shallow or undersized foundations. Not built for the ground conditions or for later additions.
• Dolomite. In some areas, sinkholes and subsidence need a specialist dolomite investigation.

Cosmetic Cracks or Structural Movement

• Often cosmetic. Fine cracks in plaster, cracks at joins between different materials and shrinkage cracks that do not change.
• Worth an assessment. Stepped or diagonal cracks through brickwork, cracks that keep growing, sloping floors, sticking doors and windows, or gaps at skirtings and ceilings.

Crack width on its own does not tell you the cause. Pattern, location, direction and whether the crack is still moving matter more.
