Access
Ties are fitted across the whole of each affected elevation, so scaffold or a tower is usually needed above ground floor. We plan access around conservatories, extensions, neighbours’ land and any parking that must be suspended.
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.
Symptoms that point to wall tie replacement
- Cracked render with a regular horizontal pattern
- Outer brickwork bowing or bulging, often worst near the top
- The roof edge or verge lifting slightly above the brickwork

Methods for wall tie replacement
Removing old ties and rebedding
On badly cracked elevations the old ties are cut out from the outer face, the joints raked and rebedded, and the brickwork repointed. It is more work than isolation but removes the source of expansion entirely. An engineer or the survey report usually specifies where this is needed.
Best for: Elevations with severe cracking or lifting
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

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 should I budget for wall tie replacement in Stockton-on-Tees?
Guide prices for wall tie replacement in Stockton-on-Tees start from about £1,650 per house, including VAT, on North East 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 Stockton-on-Tees?
Yes, Stockton-on-Tees is covered, along with postcode districts TS18, TS19, TS20. We also cover nearby Thornaby-on-Tees and Middlesbrough.
Why do houses in County Durham crack?
Much of County Durham sits on the Durham Coalfield, worked for centuries, often under a cover of glacial clay. Many former pit villages have recorded mine workings, and coal mining searches are standard for property here. 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.
