Structural repair costs in 2026
By Structural Repairs UK · Updated 2026-11-09
Structural repair costs in 2026 range from about £80 per metre for crack stitching to £3,500 per metre of wall for mini-piled underpinning, with most single repairs falling between a few hundred pounds and a few thousand. All figures here are guide prices including VAT; they vary by region and access and are confirmed in writing after a survey.
How much do structural repairs cost?
Most structural repairs cost between a few hundred and a few thousand pounds, while foundation work can run well into five figures. The figures in this guide are 2026 guide prices including VAT at 20 percent, set against a West Midlands baseline. Prices elsewhere are scaled for region, so London guides run about a quarter higher. Your actual price depends on the survey, the specification and access, and you get it as a fixed price in writing once the repair is specified.
What do crack and wall repairs cost?
Most crack and wall repairs cost from a few hundred pounds to around £5,000 (wall ties on a semi-detached house), because they need little excavation; bigger rebuilds, such as the top of a gable, can cost more. The guide prices below are for the work itself; scaffolding, internal making good and redecoration are often extra and depend on the building. Where a crack needs an engineer’s view first, an inspection and report is a guide £500 to £2,000.
- Crack stitching: £80 to £180 per metre of crack
- Single crack, outside only, up to about 2 m: £400 to £900
- Wall ties, semi-detached house: £2,500 to £5,000
- Lateral restraint for a typical gable: £1,000 to £3,000
- Rebuilding the top of a gable: £3,000 to £9,000
- Chimney repointing and minor repairs: £500 to £2,000
What do lintel, arch and timber repairs cost?
Replacing a lintel over a standard window or door is a guide £750 to £2,500 inc VAT, and a wide or bay opening £2,000 to £4,500. Rebuilding a brick arch on one side is about £900 to £1,300. In timber, splicing or sistering a damaged floor joist is about £250 to £400 per joist, and a whole room of joists and boards £2,000 to £6,000. Repairing or doubling a roof rafter is about £300 to £600, and purlin and strut strengthening £1,200 to £3,000 per roof.
What do underpinning and ground stabilisation cost?
Underpinning costs a guide £1,000 to £3,500 per metre of wall and resin injection £800 to £1,500, so the length of wall affected makes the biggest difference to the total. Most subsidence claims are fixed without underpinning, so check with your engineer whether you need it before budgeting for it. Monitoring, where needed, adds to the cost and the timescale but helps make sure the repair is the right one.
- Mass-concrete underpinning: £1,000 to £1,500 per metre
- Beam-and-base underpinning: £1,500 to £2,500 per metre
- Mini-piled underpinning: £2,000 to £3,500 per metre
- Engineer’s design and building control fees: £800 to £2,500 per scheme
- Resin injection: £800 to £1,500 per metre of wall
- Typical resin injection project: £5,000 to £15,000
- Crack monitoring with three seasonal readings: £1,450 to £2,400
What drives the cost of a structural repair?
Access and the extent of the damage drive the cost of most structural repairs more than anything else. Work high up a wall needs scaffolding, at a guide £600 to £1,800 per elevation for wall tie work, and tight sites slow excavation and plant. The number of metres to stitch, tie or underpin sets the scale. Region matters, because labour and material costs differ around the UK. Hidden problems found once work starts, such as rotten timbers or poor foundations, can change the scope, and any change should be agreed in writing first.
Are engineer fees, building control and VAT included?
VAT at 20 percent is included in these guide prices, but engineer’s fees and building control charges are usually listed separately and depend on the job. Underpinning and other notifiable structural work needs building control approval and inspections in England and Wales, with design and building control fees at a guide £800 to £2,500 per scheme, and a building warrant in Scotland. Where the repair needs an engineer’s design or sign-off, an independent chartered structural engineer is appointed, and we can arrange this. Ask any quote to show these items separately.
How do I get an accurate price?
The quickest route to an accurate price is to send clear photos with a ruler or gauge in shot, plus any engineer’s or loss adjuster’s report, for a free initial assessment from your photos or a call. If the cause is unclear, an inspection or monitoring may come first. Once the repair is specified, you get a no-obligation written quote and a fixed price in writing. For insurance work, we can price to your loss adjuster’s or engineer’s schedule. Tell your insurer before permanent repairs start.
Questions about this guide
Why are structural repair prices higher in London?
Structural repair prices are usually higher in London because labour, parking, waste removal and access all cost more, and sites are often tighter. Our guide figures are scaled by region from a West Midlands baseline, and London guides run about a quarter higher. Your written quote reflects the actual site, not just the region.
Does insurance pay for structural repairs?
Insurance may pay for structural repairs caused by an insured event such as subsidence, heave or landslip, subject to your policy terms and excess, which is commonly about £1,000 for subsidence. Gradual deterioration, such as corroded wall ties or old lintels, is often not covered. Check your policy and tell your insurer before permanent repairs start.
Is there a minimum charge for small repairs?
Yes, small jobs usually carry a minimum visit charge, because setting up, travel and materials cost much the same however short the repair. For crack stitching, the guide minimum is about £350 to £500 inc VAT. Grouping several small repairs into one visit is often better value. Prices vary by region and access.
