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.
Relay and ventilate
Boards are relaid or replaced, skirting refitted and air bricks cleared or added outside. We point out anything that would let damp back in, such as soil heaped against the wall, so the repair lasts.
Symptoms that point to floor joist repairs
- Ceiling cracks below that follow the line of the joists
- Soft or spongy boards near outside walls, hearths or the bathroom
- 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
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
Rules for floor joist repairs in Scotland

Frequently asked questions
How much will floor joist repairs cost in Stranraer?
Guide prices for floor joist repairs in Stranraer start from about £240 per joist, including VAT, on Scotland rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Stranraer?
We do. Stranraer and the surrounding area are covered, including nearby Dumfries and Galloway. A free initial assessment from your photos is the first step.
Is the ground in Dumfries and Galloway prone to subsidence?
Dumfries and Galloway is mainly older hard rock and red sandstone with glacial deposits, and soft estuarine ground along the Solway coast. 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.
