Subsidence repairs in Milford Haven
Tapered cracks around the windows or doors of a Milford Haven home are worth taking seriously without assuming the worst. In most cases the cause can be found and removed, and the house then needs crack stitching and making good rather than new foundations.

How we usually approach subsidence repairs
Remove the cause, then repair
Most subsidence is dealt with this way. The drain is repaired or the vegetation managed, the house is watched to confirm it has stabilised, and then the cracks are stitched, repointed and made good inside. It is the least disruptive route and usually the cheapest.
Best for: Clay movement or drain leaks where the cause can be removed
Crack stitching and making good
Once movement has stopped, cracked brickwork is cut along the bed joints, stainless helical bars are bonded in to tie the wall together, and the joints are repointed to match. Inside, plaster is renewed along the crack line before redecoration.
Best for: Category 1 to 3 cracking in walls that are otherwise sound
What happens during subsidence repairs, step by step?
Find the cause
An independent chartered structural engineer inspects the house and, where needed, arranges a drain survey, trial pits or soil tests. We can arrange the engineer. The aim is to know what is moving, and why, before money goes on repairs.
Deal with the cause
Drains are repaired, vegetation is managed on the engineer’s advice, or a foundation scheme is designed if nothing else will work. Where monitoring is recommended, readings run for several months to show the movement has stopped.
Written quote
We price the agreed repair and confirm a fixed price in writing once it is specified. If there is an insurance claim, we can price to the loss adjuster’s or engineer’s schedule instead of our own scope.
Rules for subsidence repairs in Wales

Questions about subsidence repairs in Milford Haven
What is the price of subsidence repairs in Milford Haven?
Guide prices for subsidence repairs in Milford Haven start from about £2,300 per property, 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 carry out subsidence repairs in Milford Haven?
Yes, Milford Haven is covered, along with postcode districts SA73. We also cover nearby Haverfordwest.
Does the ground around Milford Haven cause cracking?
The western edge of the South Wales coalfield lies beneath Llanelli, Ammanford and parts of Pembrokeshire, while the rest of the area is older hard rock with glacial deposits in the valleys. Only an investigation can say why a particular building has moved.
Can I sell a house that has had subsidence?
Yes, though buyers and lenders will want paperwork. Keep the engineer’s report, monitoring results, the repair specification and any building control sign-off. A repaired house shown to be stable is far easier to sell than one with an open problem.
How do I know if cracks are subsidence?
Subsidence cracks are usually tapered, run diagonally from door and window corners, and show on both faces of the wall. Fine vertical cracks in new plaster are more often shrinkage. An engineer’s inspection, sometimes with monitoring, is the reliable way to tell.
