Subsidence repairs in Falmouth
Tapered cracks around the windows or doors of a Falmouth 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.

Why does the ground in Cornwall matter for subsidence repairs?
Falmouth, Cornwall: about 32,000 residents across postcode districts TR11. Nearby places we cover include Truro (8 miles), Redruth (9 miles) and Camborne (11 miles).
Shrinkable clay is less common in Cornwall than in south-east England. Old metal-mine shafts and workings are recorded in places, so mining searches are routine for some properties. What you mostly find across Cornwall: granite and slate-stone cottages, cob buildings, Victorian terraces and post-war estates.
Symptoms that point to subsidence repairs
- Diagonal cracks wider at the top, running from window or door corners
- Doors and windows that start to stick or no longer close
- A gap opening between the skirting board and the floor

Methods for subsidence repairs
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
Foundation strengthening
Where the ground cannot be made stable, the load is carried down to firmer soil by underpinning, a beam-and-base scheme, mini-piles or resin injection, depending on the soil and access. It is designed by an engineer and is the exception, not the rule.
Best for: Ongoing movement where removing the cause has not worked
From first photo to finished repair
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.
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.
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.
Frequently asked questions
What is the price of subsidence repairs in Falmouth?
Guide prices for subsidence repairs in Falmouth 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 Falmouth?
Yes. We take enquiries from across Falmouth, including TR11, and from nearby places such as Truro and Redruth. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Falmouth cause cracking?
Cornwall is mostly granite and slate with little shrinkable clay, so clay subsidence is less common than in the south-east. Historic tin and copper mining has left shafts and workings in places such as Camborne and Redruth, and mining searches are routine there. 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.
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.
