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
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
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.
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
What is the price of wall tie replacement in Newton Aycliffe?
Guide prices for wall tie replacement in Newton Aycliffe 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.
Do you carry out wall tie replacement in Newton Aycliffe?
Yes. We take enquiries from across Newton Aycliffe, including DL4, DL5, and from nearby places such as Bishop Auckland and Spennymoor. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Newton Aycliffe cause cracking?
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.
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.
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.
