Crack stitching repairs the wall itself, restoring its structural strength and disguising the damage.

Key points

  • Stainless steel helibars are bedded into raked-out mortar joints across the crack.
  • Bars are anchored with a high-strength grout and re-pointed flush.
  • The wall regains structural continuity and the crack is invisible once repainted.
  • Typical UK cost £800–£3,000 depending on length and access.

If you’re uncertain about your own situation, send a photo of the crack and a brief description and we’ll give you an honest, free expert opinion, usually the same day.

Working with a UK subsidence specialist

A good specialist starts by listening. The single most useful thing you can do before any visit is to gather the evidence: dated photographs of every crack, a note of when they appeared, any history of building work, the location of large trees, and any drainage issues you are aware of. Five minutes of preparation here saves a great deal of time on site and almost always leads to a sharper diagnosis.

Independence matters too. The right adviser is not selling you a repair before they have understood the problem. Watch for anyone recommending underpinning at the first visit without monitoring, soil information, or drainage checks. The cause comes first, the repair second, and any reputable firm will say so in writing.

When you are ready, send a photo of the crack and a brief description through the form on this page. There is no obligation, no sales call, and no charge. You will get an honest opinion, a sensible next step, and if needed an introduction to a chartered surveyor in your area.

Most homeowners we hear from are somewhere on a spectrum between mildly curious and seriously worried, and almost everyone is reassured by the same simple framework. Look at the crack with fresh eyes. Measure it. Photograph it next to a coin or a tape. Note where it sits and whether it appears on both sides of the wall. Then give it a few weeks, and look again. That short period of patience filters out the everyday plaster shrinkage and seasonal movement that accounts for the great majority of reported cracks, and lets a specialist focus on the small number of cases where a survey will genuinely add value.

The British housing stock is famously varied: Georgian townhouses, Victorian terraces, inter-war semis, post-war estates, timber-frame new builds, and rural stone cottages all crack differently and for different reasons. A specialist who has seen hundreds of each type can usually rule causes in or out from a clear photograph alone, and that is the value of a free assessment, you get the benefit of pattern recognition built up over a career without paying for a site visit you may not need.

We also believe strongly in plain English. Subsidence, heave, settlement, thermal movement, shrinkage, deflection, sulfate attack and a dozen other terms get used loosely in casual conversation, and that imprecision is how homeowners end up worried about the wrong thing. When you receive a reply from us it will avoid jargon where possible, define it where it cannot be avoided, and tell you clearly which of those phenomena, if any, is likely to apply to your situation.

Common questions

Do you charge for the photo assessment?
No. The photo assessment is free and there is no obligation to proceed with anything further.
Are yvetted specialists qualified?
Yes. We work only with RICS chartered surveyors and structural engineers experienced in UK subsidence.
How do I know I am getting honest advice?
We are paid by clients who choose to proceed with a survey or repair. Telling you a crack is fine when it is fine is part of how that trust is built.
What information should I send with the photo?
Approximate age of the property, when you first noticed the crack, whether it appears inside, outside or both, any nearby mature trees, and any recent drainage issues or building work. The more context, the sharper the opinion.
Do you cover Scotland, Wales and Northern Ireland?
Yes. Our specialist network covers the whole of the UK. Geology and typical causes differ by region, and your enquiry is matched to a surveyor who works in your area regularly.
