Are crack stitches a long-term fix?

When the underlying cause has been resolved, helical crack stitches provide a permanent restoration of wall tensile strength.

Will I need building control involvement?

Most structural foundation work requires building control inspection and a sign-off certificate.

Are extensions and conservatories harder to repair?

They can be. The original construction is often less well documented, so the specialist allows extra time for survey work on these structures.

Foundation Repair in Bexley

Fix failing footings properly so the cracks stop coming back season after season.

Worried about it? Here's what happens next.

Older south London homes were built on shallow Victorian footings that were never designed for modern extensions, conservatories or the long dry summers we now get. If yours has started moving, the priority is the right diagnosis. The wrong fix on the wrong foundation either fails or causes new damage.

1. Full diagnostic survey

Cracks, floors, drains and soil all checked together. Drainage faults are a top cause.

2. Method chosen to fit the cause

Stitching for cracked masonry, resin for soft ground, mass concrete where support is missing.

3. Engineer-signed repair

Building control sign-off and structural certificate go on file with the work.

Will Foundation Repair work for my home?

This is right for you if…

✓ Victorian and Edwardian terraces with shallow original footings
✓ Extensions or conservatories pulling away from the main structure
✓ Properties where leaking drains have washed material out from under footings

This isn't the answer if…

× New-build properties under structural warranty (use the warranty first)
× Pure cosmetic crack repair with no underlying ground issue

What it will cost and how long it takes

Cost

Foundation repair in south east London typically costs £6,000 to £30,000 depending on the method and the length of the affected elevation. Most insurance-led cases sit comfortably within standard cover.

Timeline

Three to five days for resin stabilisation, up to six weeks for full footing replacement on a long elevation. You stay in the home throughout.

What you actually get

Permanent fix, not a patch

Repairs address the cause of the movement, not just the visible damage.

Drainage checked at the same time

Leaking drains are dealt with so the underlying problem doesn't return.

Engineer-signed paperwork

Every repair finishes with a structural sign-off you can keep on file.

Method matched to the footing

No one-size-fits-all approach. The survey drives the method.

Will my insurance pay for it?

Most foundation repair tied to active subsidence is insurance-recoverable subject to the standard excess. The specialist liaises with the insurer and produces the reports the claims handler needs.
