Concrete repairs in Exeter
Spalling concrete on a Exeter balcony, canopy or lintel almost always starts with the steel inside. Once carbonation or salts reach the bars, they rust and swell, and the concrete breaks away along their line until the steel is repaired and protected.

Is Devon prone to ground movement?
With roughly 130,000 people, Exeter spans postcode districts EX1, EX2, EX3, EX4 in Devon. If you are just outside Exeter, we also cover Exmouth (9 miles), Tiverton (12 miles) and Newton Abbot (14 miles).
Shrinkable clay is less common in Devon 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 Devon: cob and stone cottages, Victorian terraces in Exeter, Plymouth and Torbay, and post-war estates.
Which repair method suits a home in Exeter?
Protective coatings and sealing
After repair, an anti-carbonation coating, a waterproof deck membrane on a balcony, or a penetrating sealer slows the return of moisture and carbon dioxide. Restoring drips, upstands and falls so water drains away is as important as the coating itself.
Best for: Extending the life of repaired balconies and canopies
Patch repair
Loose and contaminated concrete is broken out behind the bar, the steel is cleaned of rust and primed, and the section is rebuilt with a repair mortar. The edges are cut square so the patch does not feather out and fail. A protective coating may be applied over the whole surface afterwards.
Best for: Localised spalling around rusting bars
What happens when we carry out concrete repairs in Exeter?
Photos and a description
Send photos of the damage close up and from a distance, plus the whole balcony, canopy or elevation. Tell us roughly how old the building is and whether anything has fallen, so we can judge whether to make it safe first.
Engineer where needed
If the steel has lost significant section, or the element carries a balcony, stair or wall, an independent chartered structural engineer is appointed to assess and specify. We can arrange this, and the repair follows their scope.
Break out, repair, protect
Damaged concrete is cut back to sound material, steel cleaned and primed, and the section rebuilt and cured. Cracks are injected, then the surface is coated and drainage details put right so water runs off rather than sitting.
Signs you may need concrete repairs
- Fine cracks running in straight lines along the line of the reinforcement
- Damp patches, white deposits or drips on a balcony or canopy underside
- Chunks or flakes of concrete breaking away from edges and soffits

Is the ground in Devon prone to subsidence?
Devon's ground is mostly older mudstones, sandstones and granite, so shrinkable-clay subsidence is less widespread than further east. Older solid-walled and cob buildings, steep sites and retaining walls are the more common structural concerns. Only an investigation can say why a particular building has moved.
Can you repair a cracked concrete lintel?
Often, yes. Spalling and small cracks in a concrete lintel can be patch repaired and the steel treated. If the lintel is badly cracked, sagging or the bars have lost much of their section, replacement is usually better, and the opening is propped while it is done.
Is spalling concrete dangerous?
It can be, mainly because pieces may fall from balconies, canopies and soffits above doors or paths. It also means the steel is losing strength over time. Fence off the area below any loose concrete, keep people off a balcony that is badly affected, and have it assessed soon.
