What is the ground like in Shropshire?
We cover Oswestry and its postcode districts SY11, part of Shropshire, with a population of roughly 19,000. We also take enquiries from nearby Shrewsbury (16 miles) and Chester (24 miles).
Shropshire has a mix of ground, with clay in some places and firmer rock in others. Parts of Shropshire lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Shropshire, most homes are timber-framed and brick town houses, industrial terraces around Telford, and new-town estates.

Which repair method suits a home in Oswestry?
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
What happens when we carry out floor joist repairs in Oswestry?
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.
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.
Floor joist repairs in Oswestry: questions and answers
How much should I budget for floor joist repairs in Oswestry?

Why do houses in Shropshire crack?
Shropshire has very varied rock, from Mercia Mudstone on the north Shropshire plain to the Coalbrookdale coalfield under Telford, where historic shallow coal, clay and ironstone workings are widespread. 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.
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.
