Concrete repairs in Nantwich
Where flats and houses in Nantwich and across Cheshire have concrete balconies, canopies or lintels several decades old, carbonation has had time to reach the reinforcement. That is when spalling and straight-line cracking tend to appear.

Why does the ground in Cheshire matter for concrete repairs?
Nantwich (CW5) has around 17,000 residents and sits in Cheshire. If you are just outside Nantwich, we also cover Crewe (4 miles), Sandbach (8 miles) and Winsford (8 miles).
Parts of Cheshire have clay that can shrink near trees in dry spells. Historic brine and salt working has caused ground movement in parts of Cheshire in the past. Typical buildings in Cheshire: Brick terraces in Crewe, Northwich and Warrington, Victorian villas in Chester, and inter-war and post-war semis.
What happens during concrete repairs, step by step?
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.
Survey and tapping test
On site we tap the surface to find hollow areas, check the steel where it is exposed and note drainage. Where the extent is unclear, a cover meter, carbonation test or chloride test may be advised before repair.
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.
What to look for before calling about concrete repairs
- Hollow sound when the surface is tapped with a hammer
- Rust-coloured stains or streaks running down the concrete surface
- Exposed steel bars showing where concrete has fallen away

How we usually approach concrete repairs
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
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
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.
Questions about concrete repairs in Nantwich
How much will concrete repairs cost in Nantwich?
Guide prices for concrete repairs in Nantwich start from about £80 per m², including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Nantwich?
We do. Nantwich and the surrounding area are covered, including nearby Crewe and Sandbach. A free initial assessment from your photos is the first step.
Is the ground in Cheshire prone to subsidence?
Most of Cheshire is glacial till over Mercia Mudstone. Around Northwich and the Weaver valley, historic salt and brine extraction has caused subsidence in the past, and a separate brine subsidence compensation scheme exists for parts of the county. Only an investigation can say why a particular building has moved.
Do you repair concrete on blocks of flats?
Yes, we repair concrete on houses, flats and small commercial buildings, including balconies, walkway edges, canopies and lintels. For flats, the freeholder, managing agent or owners’ association normally instructs the work. We can price to an engineer’s schedule where one has been prepared.
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.
