Methods for concrete repairs
Recasting or strengthening
Where steel has lost much of its section, or a lintel or canopy is too far gone to patch, the element is propped and rebuilt, replaced or strengthened to an engineer’s design. It is less common, but sometimes the more lasting option for small canopies and old precast lintels.
Best for: Badly corroded lintels, canopies and balcony edges
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
From first photo to finished repair
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.
Written quote
You receive a no-obligation written quote setting out the estimated area of patching, the length of crack injection, coatings and access. It becomes a fixed price in writing once the repair is specified, with any re-measure terms stated clearly.
Symptoms that point to concrete repairs
- Hollow sound when the surface is tapped with a hammer
- Damp patches, white deposits or drips on a balcony or canopy underside
- Exposed steel bars showing where concrete has fallen away
Rules for concrete repairs in England
Like-for-like repairs such as crack stitching and repointing do not usually need building control approval in England, but anything that changes or strengthens the structure, such as underpinning or rebuilding a wall, does. If the work touches a party wall, the Party Wall etc. Act 1996 may apply.
Frequently asked questions
How much will concrete repairs cost in Enfield?
Guide prices for concrete repairs in Enfield start from about £105 per m², including VAT, on London rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Enfield?
Yes, Enfield is covered, along with postcode districts EN1, EN2, EN3, N9. We also cover nearby Cheshunt and Haringey.
Is the ground in Greater London prone to subsidence?
Most of Greater London sits on London Clay, among the most shrinkage-prone ground in the UK, with river gravels along the Thames. Subsidence claims here are among the most frequent in the country, especially after dry summers and near street and garden trees. Only an investigation can say why a particular building has moved.
What is spalling concrete?
Spalling is concrete breaking away from the surface in flakes or chunks. In reinforced concrete it is usually caused by the steel inside rusting and expanding, which pushes the cover off. It often follows a straight line where a bar sits close to the surface, with rust staining nearby.
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.
