What should you know about the ground under Kenilworth?
With roughly 22,000 people, Kenilworth spans postcode districts CV8 in Warwickshire. Nearby, we also cover Warwick (5 miles), Coventry (5 miles) and Leamington Spa (5 miles).
Warwickshire has a mix of ground, with clay in some places and firmer rock in others. Parts of Warwickshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Warwickshire: Regency houses in Leamington Spa, timber-framed buildings in Stratford and Warwick, and brick terraces and estates in the north.
Symptoms that point to floor joist repairs

Methods for floor joist repairs
Sleeper walls and ventilation
Settled or damp sleeper walls are rebuilt on a sound base with a damp-proof course under new timber plates. Blocked air bricks are cleared, extra ones added where the void has dead spots, and soil or paving heaped against the outside wall is lowered.
Best for: Damp ground floor voids or joists on poor supports
Sistering a joist
A new length of treated timber, the same depth as the original, is bolted or screwed alongside the damaged joist so the two share the load. It is the quickest fix for a notched, cracked or sagging joist that is otherwise sound, usually after lifting a few boards.
Best for: Cut, cracked or sagging joists with sound ends
From first photo to finished repair
Photos and a call
Send photos of the dip or soft area, the outside wall at ground level and any air bricks. A short call about when it started, and any recent plumbing or heating work, tells us whether the problem is local or widespread.
Lift boards and inspect
On site we lift a few boards where the floor is worst and check the joist ends, sleeper walls and void with a moisture meter. Outside, we look for high ground, blocked vents and leaks keeping the timber wet.
Repair the structure
Boards are lifted and numbered if they are going back, and rotten timber is cut out. New treated timber is fixed and checked with a level before strutting, hangers and any restraint straps go in.
Rules for floor joist 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
What is the price of floor joist repairs in Kenilworth?
Guide prices for floor joist repairs in Kenilworth start from about £250 per joist, including VAT, on West Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out floor joist repairs in Kenilworth?
Yes, Kenilworth is covered, along with postcode districts CV8. We also cover nearby Warwick and Coventry.
Does the ground around Kenilworth cause cracking?
Much of Warwickshire is Mercia Mudstone and Lias clay, with the Warwickshire coalfield under Nuneaton and Bedworth in the north. Clay soils near trees can shrink in dry summers. Only an investigation can say why a particular building has moved.
What is sistering a floor joist?
Sistering is fixing a new length of timber alongside an existing joist so the two share the load. It strengthens a notched, cracked or sagging joist without removing it, so it is quicker and less disruptive than replacement.
Do I need building control for floor joist repairs?
Usually not for like-for-like repairs to a few joists, but replacing a whole floor structure can be building work. In Scotland that generally needs a building warrant, and in Northern Ireland council building control applies. We deal with building control where the work needs it.
