Floor joist repairs in Edinburgh
Houses in Edinburgh and across Edinburgh and the Lothians with suspended timber ground floors rely on dry walls and a ventilated void to stay sound. When either fails, rot usually starts at the edges of the room long before anything shows in the middle.

How we usually approach floor joist repairs
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
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
What happens during floor joist repairs, step by step?
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 Scotland
In Scotland, small repairs often do not need a building warrant, but structural alterations and strengthening generally do. Check with the council’s building standards service if unsure; there is no Party Wall Act in Scotland.
Questions about floor joist repairs in Edinburgh
How much will floor joist repairs cost in Edinburgh?
Guide prices for floor joist repairs in Edinburgh 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 Edinburgh?
Yes. We take enquiries from across Edinburgh, including EH1, EH2, EH3, and from nearby places such as Musselburgh and Bonnyrigg. Send photos for a free initial view and we will tell you what happens next.
Is the ground in Edinburgh and the Lothians prone to subsidence?
Edinburgh is volcanic and sedimentary rock with glacial till, while the Midlothian and East Lothian coalfields and oil-shale workings in West Lothian have left recorded mine workings and bings. Only an investigation can say why a particular building has moved.
Can floor joists be repaired without taking up the whole floor?
Yes, in most cases only the boards over the affected joists need lifting, and three or four boards are often enough to sister a joist or splice a rotten end. Widespread rot is the exception, because the whole floor must come up to remove the decay.
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.
