Wall tie replacement in Sleaford
Plenty of cavity-walled houses, in Sleaford 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.

Why does the ground in Lincolnshire matter for wall tie replacement?
With roughly 17,000 people, Sleaford spans postcode districts NG34 in Lincolnshire. Nearby, we also cover Grantham (11 miles), Boston (16 miles) and Lincoln (17 miles).

Typical buildings in Lincolnshire: Victorian terraces in Lincoln and Grimsby, fenland brick houses, seaside bungalows and post-war estates.
How we usually approach 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
What happens during wall tie replacement, step by step?
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.
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.
What to look for before calling about wall tie replacement
- Cracked render with a regular horizontal pattern
- Outer brickwork bowing or bulging, often worst near the top
- Horizontal cracks along mortar joints, repeating every few brick courses

Questions about wall tie replacement in Sleaford
What is the price of wall tie replacement in Sleaford?
Guide prices for wall tie replacement in Sleaford start from about £1,750 per house, including VAT, on East Midlands 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 Sleaford?
Yes, Sleaford is covered, along with postcode districts NG34. We also cover nearby Grantham and Boston.
Does the ground around Sleaford cause cracking?
Lincolnshire has Lias, Oxford and Kimmeridge clays on the vales, chalk on the Wolds and soft silts and peat in the fens around Boston and Spalding. Fen ground and clay can both settle or shrink in dry years. Only an investigation can say why a particular building has moved.
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.
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.
