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.

Methods for floor joist repairs

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

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

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 Spalding?

Guide prices for floor joist repairs in Spalding start from about £245 per joist, including VAT, on East Midlands rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Does the ground around Spalding cause cracking?

Lincolnshire has Lias, Oxford and Kimmeridge clays on the vales, chalk on the Wolds and soft silts and peat in the fens around Boston and Spalding. Fen ground and clay can both settle or shrink in dry years. 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.

Will my insurance pay for rotten floor joists?

Usually not, because rot, woodworm and gradual wear are standard exclusions. Damage from a sudden escape of water, or a floor that dropped through subsidence, may be treated differently. Check your policy, and tell your insurer before permanent repairs start if either applies.
