What is the ground like in Northamptonshire?

Northamptonshire is one of the parts of the UK where clay soils are most likely to move with the seasons. Historic ironstone working has left disturbed ground in places. What you mostly find across Northamptonshire: ironstone and limestone cottages, Victorian terraces in Northampton and Kettering, and new-town estates in Corby.
How we usually approach wall tie replacement
Partial rebuild of the outer leaf
If a section of the outer leaf has bulged too far to be tied back, it is carefully taken down and rebuilt with new ties built in as the work goes up. This is uncommon, and is usually limited to a gable top, a parapet or a panel under a window.
Best for: Outer leaf too distorted to tie back safely
Isolating the old ties
Where the old ties are swelling and cracking the brickwork, fitting new ties alone may not stop further damage. Each old tie can be isolated, usually by cutting it through within the cavity or sleeving its outer end, so it can no longer lift the outer leaf as it continues to corrode.
Best for: Thick mild steel ties still causing horizontal cracking
What happens during wall tie replacement, step by step?
Tie survey
A metal detector locates the existing ties and shows their pattern. Small holes are then drilled at sample points and a borescope passed into the cavity to see the tie condition, type and embedment. The holes are made good afterwards.
Install the new ties
New stainless ties are drilled and fixed to the specified grid, with closer spacing around windows, doors and the roofline. Sample ties can be pull-tested to confirm they are holding in your particular brick and block.
Deal with the old ties and make good
Old ties are isolated or removed where the report calls for it, cracked joints are raked out and repointed, and drilled holes are filled in matching mortar. A written note of tie positions and findings goes in your property file.
What to look for before calling about wall tie replacement
- Outer brickwork bowing or bulging, often worst near the top
- The roof edge or verge lifting slightly above the brickwork
- Horizontal cracks along mortar joints, repeating every few brick courses

Rules for wall tie replacement in England
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.
Questions about wall tie replacement in Wellingborough
How much should I budget for wall tie replacement in Wellingborough?
Guide prices for wall tie replacement in Wellingborough start from about £1,750 per house, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Wellingborough?
Yes, Wellingborough is covered, along with postcode districts NN8. We also cover nearby Rushden and Kettering.
Why do houses in Northamptonshire crack?
Northamptonshire sits largely on Lias clay and Jurassic ironstones and limestones, with historic ironstone quarrying around Corby and Kettering. The clay vales are prone to shrinkage near trees. Only an investigation can say why a particular building has moved.
Is wall tie failure covered by insurance?
Usually not, because insurers treat it as gradual deterioration. Damage caused by a sudden event, such as part of a wall collapsing in a storm, may be treated differently under some policies. Check your policy wording, and tell your insurer if you are unsure.
How do I know if my wall ties have failed?
The clearest sign is horizontal cracking in the mortar joints repeating every few courses, often with a bulge or a lifted roofline. Wire ties can fail with no cracking at all, so a tie survey with a metal detector and borescope is the only reliable check.
