Why does the ground in Gloucestershire matter for floor joist repairs?
Gloucester (GL1, GL2, GL4) has around 130,000 residents and sits in Gloucestershire. Nearby places we cover include Cheltenham (7 miles), Stroud (8 miles) and Tewkesbury (9 miles).
Gloucestershire has a mix of ground, with clay in some places and firmer rock in others. Parts of Gloucestershire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Gloucestershire, most homes are Cotswold stone cottages, Regency terraces in Cheltenham, and brick estates around Gloucester.
What to look for before calling about floor joist repairs
- A musty smell, or fungal strands showing between the boards

How we usually approach floor joist repairs
Splicing ends and fitting hangers
Where only the end has rotted, it is cut back to sound timber and a new piece is fixed alongside, bearing on the wall or on a new joist hanger. Missing or under-nailed hangers elsewhere are replaced at the same time. The damp in the wall must be fixed too.
Best for: Rotten joist ends in damp solid walls
Replacing joists and boards
When rot or woodworm runs through most of a floor, it is usually cheaper to replace the joists, strutting and boards together. Where joists run parallel to an outside wall, restraint straps tie the new floor back to it so the wall keeps its lateral support.
Best for: Widespread rot, or a whole floor that has dropped
What happens during floor joist repairs, step by step?
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.
Written quote
You get a no-obligation written quote listing which joists are sistered, spliced or replaced and any sleeper wall or ventilation work. It becomes a fixed price in writing once the repair is specified.
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.
Questions about floor joist repairs in Gloucester
How much should I budget for floor joist repairs in Gloucester?
Guide prices for floor joist repairs in Gloucester start from about £260 per joist, including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Gloucester?
We do. Gloucester and the surrounding area are covered, including nearby Cheltenham and Stroud. A free initial assessment from your photos is the first step.
Why do houses in Gloucestershire crack?
The Severn vale around Gloucester, Cheltenham and Tewkesbury is Lias and Mercia Mudstone clay, the Cotswolds are limestone, and the Forest of Dean has a historic coalfield. Parts of South Gloucestershire around Kingswood also lie on old Coal Measures. Only an investigation can say why a particular building has moved.
Why is my floor bouncy?
A bouncy floor usually means the joists are deflecting too much, often because they span too far, have lost their strutting or have been weakened by notches. It rarely means imminent failure, but it is worth checking, especially if the bounce appeared after work in the room.
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.
