Is Cumbria prone to ground movement?
We cover Carlisle and its postcode districts CA1, CA2, CA3, part of Cumbria, with a population of roughly 78,000. Neighbouring towns we cover: Penrith (17 miles).
Shrinkable clay is less common in Cumbria than in south-east England. Parts of Cumbria lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. What you mostly find across Cumbria: stone-built terraces and farmhouses, sandstone town houses in Carlisle and post-war estates.

Repair options we may recommend
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
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
What to expect when we carry out floor joist repairs
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.
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.
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.
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.
Your floor joist repairs questions
How much should I budget for floor joist repairs in Carlisle?
Guide prices for floor joist repairs in Carlisle start from about £240 per joist, including VAT, on North West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Can you survey a property in Carlisle?
We do. Carlisle and the surrounding area are covered, including nearby Penrith. A free initial assessment from your photos is the first step.
Why do houses in Cumbria crack?
Cumbria's ground is largely hard rock and glacial deposits, with the West Cumberland coalfield around Whitehaven and Workington where historic coal workings are recorded. Stone walls and older lime mortars feature in much of the housing. 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.
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.
