Subsidence repairs in Westbury

Tapered cracks around the windows or doors of a Westbury 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?

  1. Send photos or call

    Send photos of the cracks with a coin or tape for scale, and say when you first noticed them. We give a free initial assessment and suggest whether an engineer, a drain survey or your insurer comes first.

  2. 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.

  3. Repairs and making good

    Cracks are stitched and repointed outside, plaster is renewed along the crack lines inside, and sticking doors are eased. Where the work needs it, we deal with building control and hand over the paperwork.

Rules for subsidence repairs in England

In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Questions about subsidence repairs in Westbury

What is the price of subsidence repairs in Westbury?

Guide prices for subsidence repairs in Westbury start from about £2,600 per property, including VAT, on South West 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 Westbury?

We do. Westbury and the surrounding area are covered, including nearby Warminster and Trowbridge. A free initial assessment from your photos is the first step.

Does the ground around Westbury cause cracking?

Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. Only an investigation can say why a particular building has moved.

Should I cut down the tree near my house?

Not without advice, because felling a mature tree on clay can make things worse. As the roots stop drawing water, the clay swells and can lift the foundations, which is called heave. Pruning or staged removal may be advised instead. Check whether the tree is protected.

Does subsidence always need underpinning?

No, most subsidence is repaired without underpinning. When a leaking drain is fixed or nearby vegetation is managed, the ground usually stabilises and the house needs only crack repairs. Foundation work is kept for movement that continues after the cause has gone.
