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.

Symptoms that point to floor joist repairs

Floor dipping towards an outside wall or in the middle of the room

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

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 Stourbridge?

Guide prices for floor joist repairs in Stourbridge 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 Stourbridge?

We do. Stourbridge and the surrounding area are covered, including nearby Dudley and Halesowen. A free initial assessment from your photos is the first step.

Does the ground around Stourbridge cause cracking?

The West Midlands is mostly Mercia Mudstone and glacial till, with the South Staffordshire coalfield under much of the Black Country, where shallow coal and limestone workings are recorded around Dudley, Tipton and Walsall. Only an investigation can say why a particular building has moved.

What causes rot in floor joists?

Damp causes almost all joist rot. Joist ends in damp walls, voids with blocked air bricks, leaking pipes and high outside ground levels keep timber wet enough for fungi to grow. Replacing timber without fixing the damp usually means the rot returns.

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.
