Which repair method suits a home in Cramlington?
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 when we carry out floor joist repairs in Cramlington?
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.
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.

Floor joist repairs in Cramlington: questions and answers
How much will floor joist repairs cost in Cramlington?
Guide prices for floor joist repairs in Cramlington start from about £230 per joist, including VAT, on North East rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you cover Cramlington?
We do. Cramlington and the surrounding area are covered, including nearby Bedlington and Blyth. A free initial assessment from your photos is the first step.
Is the ground in Northumberland prone to subsidence?
South-east Northumberland around Blyth, Ashington and Cramlington lies on the Northumberland coalfield, worked extensively in the past, under a cover of glacial clay. The north and west are hard rock and moorland. Only an investigation can say why a particular building has moved.
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.
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.
