Wall tie replacement in Monmouth
The first clue to failing wall ties in Monmouth is usually a crack pattern: fine horizontal lines every few courses on one elevation. We confirm what is happening inside the cavity with a metal detector and borescope before recommending any new ties.

Which repair method suits a home in Monmouth?
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
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
What happens when we carry out wall tie replacement in Monmouth?
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.
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.
Signs you may need wall tie replacement

Wall tie replacement in Monmouth: questions and answers
How much will wall tie replacement cost in Monmouth?
Guide prices for wall tie replacement in Monmouth start from about £1,650 per house, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Monmouth?
We do. Monmouth and the surrounding area are covered, including nearby Chepstow and Abergavenny. A free initial assessment from your photos is the first step.
Is the ground in Gwent prone to subsidence?
The valleys of Blaenau Gwent, Torfaen and Islwyn lie on the South Wales coalfield with extensive historic workings and spoil tips, while Newport and Monmouthshire have Mercia Mudstone, alluvium and Old Red Sandstone. 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.
Do all walls of the house need new ties?
Not necessarily, because ties often fail on one exposed elevation long before the others. The survey checks each wall, and the quote covers only the elevations where ties have failed or are close to it. Sheltered walls may simply be noted for future checks.
