Typical buildings in Bedfordshire: Victorian terraces in Bedford and Luton, large inter-war and post-war estates, and newer estates on former clay pits and brickfields.

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
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
From first photo to finished repair
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
- Outer brickwork bowing or bulging, often worst near the top
- A house built before the 1980s on an exposed or coastal site
- Cracked render with a regular horizontal pattern
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 should I budget for wall tie replacement in Dunstable?
Guide prices for wall tie replacement in Dunstable start from about £1,900 per house, including VAT, on East of England 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 Dunstable?
We do. Dunstable and the surrounding area are covered, including nearby Luton and Leighton Buzzard. A free initial assessment from your photos is the first step.
Why do houses in Bedfordshire crack?
Much of Bedfordshire sits on Oxford Clay and Gault Clay, with chalk rising towards the Chilterns in the south. The clay vales shrink in dry summers and swell in wet winters, which is why seasonal cracking is common around Bedford. Only an investigation can say why a particular building has moved.
Can wall ties be replaced on a rendered house?
Yes, new ties can be fitted through render, with each drill hole made good afterwards. The repairs can show on painted render, so redecoration of the affected elevation is often worth including. Render can also hide the cracking pattern, so a survey matters more.
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.
