Structural crack repairs in Welshpool
Whether your Welshpool home is a Victorian terrace or a post-war semi, a crack follows the weakest line through the masonry. Reading that line correctly is the difference between a repair that lasts and one that splits open again next summer.

Methods for structural crack repairs
Rebuilding a cracked section
Where bricks have split or the wall has moved out of line, the damaged area is taken down and rebuilt, bonded into sound masonry on either side. Reclaimed or matched bricks keep the repair discreet, with temporary support used where needed.
Best for: Badly displaced or broken brickwork
Filling and repointing
For hairline and narrow cracks that have stopped moving, the crack line is raked out and repointed in mortar matched to the original for strength, colour and texture. Inside, plaster cracks are cut out, filled with a flexible filler and redecorated.
Best for: Cracks up to about 5 mm that are no longer moving
From first photo to finished repair
Send photos
Photograph the crack from a distance and close up, with a coin or tape measure for scale. From these we say whether it looks cosmetic, needs a visit or calls for an engineer.
Survey and record
On site we measure the width along the crack, note its pattern and check nearby drains, trees and openings. If the cause is unclear, gauges can be fixed across it and read over several months.
Deal with the cause
Leaking drains, failed ties, a sagging lintel or ground movement are put right first, sometimes through an insurance claim. Repairing a crack before its cause is fixed usually means paying for the same job twice.
Symptoms that point to structural crack repairs
- Cracks that reappear in the same place after filling and painting
- Daylight or a draught coming through a crack in an outside wall
- Stepped cracks zigzagging through the mortar joints of outside brickwork
Rules for structural crack repairs in Wales
In Wales, small like-for-like repairs do not usually need approval, but work that alters or strengthens the structure needs building control under the Welsh Building Regulations, and the Party Wall etc. Act 1996 can apply to shared walls.
Frequently asked questions
How much should I budget for structural crack repairs in Welshpool?
Guide prices for structural crack repairs in Welshpool start from about £75 per metre of crack, including VAT, on Wales rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Welshpool?
Survey visits to Welshpool are by arrangement because of travel and access. We can still give a free initial view from photos, and we tell you any travel cost before a visit is booked.
Why do houses in Powys crack?
Powys is largely older hard rock and glacial deposits, with alluvium in the river valleys. Clay shrinkage is uncommon, but older stone buildings and rubble walls bring their own structural issues. Only an investigation can say why a particular building has moved.
Can I just fill a crack and paint over it?
You can fill a fine crack that is not moving, and for many hairline cracks that is the right repair. Filling a crack that is still opening hides the evidence, and it will usually come back. If a filled crack returns within a year or two, have it assessed.
Do I need a structural engineer for a cracked wall?
Not always, since many cracks can be judged from photos and a visit. An engineer is worthwhile when cracks are wide, tapered, growing or part of a claim. Where the repair needs an engineer’s design or sign-off, an independent chartered structural engineer is appointed, and we can arrange this.
