Wall tie replacement in Didcot
Horizontal cracking on a Didcot house is easy to mistake for subsidence. Rusting wall ties leave a much more regular pattern, though, and telling the two apart early saves time, money and an unnecessary insurance claim.

What should you know about the ground under Didcot?
Didcot (OX11) has around 29,000 residents and sits in Oxfordshire. If you are just outside Didcot, we also cover Abingdon (5 miles), Oxford (10 miles) and Thatcham (14 miles).
Oxfordshire is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. Across Oxfordshire, most homes are Cotswold stone villages, Victorian terraces in Oxford and Banbury, and large post-war and new-build estates around Didcot and Bicester.

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.
Report and quote
You receive a written summary of what the survey found on each elevation, which walls need new ties, whether old ties should be isolated or removed, and a no-obligation written quote with scaffold shown separately.
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.
Symptoms that point to wall tie replacement
- Horizontal cracks along mortar joints, repeating every few brick courses
- A house built before the 1980s on an exposed or coastal site
- Cracked render with a regular horizontal pattern

Methods for wall tie replacement
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
Remedial tie installation
New stainless ties are drilled through the outer leaf into the inner leaf, then fixed by mechanical expansion or resin, depending on the masonry. They are placed to a set grid across each elevation, with extra ties around openings and at the edges. Holes are made good in matching mortar.
Best for: Walls where the original ties have failed or are missing
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.
Frequently asked questions
How much will wall tie replacement cost in Didcot?
Guide prices for wall tie replacement in Didcot start from about £2,000 per house, including VAT, on South East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Didcot?
Yes, Didcot is covered, along with postcode districts OX11. We also cover nearby Abingdon and Oxford.
Is the ground in Oxfordshire prone to subsidence?
Oxfordshire's vales sit on Oxford, Kimmeridge and Gault Clays, among the more shrinkage-prone clays in England, with Cotswold limestone in the north-west and chalk downs in the south. Only an investigation can say why a particular building has moved.
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.
Do the old wall ties have to be removed?
Not always, because thin wire ties that cannot swell are usually left in place once new ties are fitted. Thicker ties that are still expanding and cracking the wall are isolated or removed so they stop causing damage. The survey decides which applies.
