Wall tie replacement in Cambridge
Plenty of cavity-walled houses, in Cambridge as elsewhere, were built when galvanised steel ties were standard, and those ties are now reaching the end of their life. A survey shows whether yours are sound, thinning or actively swelling and cracking the brickwork.

What should you know about the ground under Cambridge?
Postcode districts CB2, CB4 cover Cambridge, a Cambridgeshire town of about 150,000 people. Nearby places we cover include Royston (12 miles), St Ives (12 miles) and Newmarket (13 miles).
Much of Cambridgeshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. What you mostly find across Cambridgeshire: Victorian terraces in Cambridge and Peterborough, fen-edge cottages, and extensive post-war and new-build estates.

How we usually approach wall tie replacement
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
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
What happens during wall tie replacement, step by step?
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.
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.
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.
Questions about wall tie replacement in Cambridge
What is the price of wall tie replacement in Cambridge?
Guide prices for wall tie replacement in Cambridge 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.
Do you carry out wall tie replacement in Cambridge?
Yes, Cambridge is covered, along with postcode districts CB2, CB4. We also cover nearby Royston and St Ives.
Does the ground around Cambridge cause cracking?
Gault Clay underlies much of the Cambridge area and Oxford Clay the west of the county around Peterborough and Huntingdon, while the northern fens are peat and silt that can shrink as they dry. Both clay and peat ground can move with the seasons. 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.
Will a mortgage lender accept wall tie replacement?
Lenders generally accept properly carried out tie replacement, but they may want to see the survey, the quote or a record of the completed work. If a valuation has flagged wall ties, a written report and itemised quote are usually what the lender or buyer needs next.
