Floor joist repairs in Lowestoft
If a plumber or electrician has recently had the boards up at your Lowestoft home, the joists they worked around are worth a look. Deep notches and holes in the wrong place weaken joists quickly, and sistering them is usually a short, tidy job.

How do local ground conditions affect floor joist repairs in Lowestoft?
With roughly 71,000 people, Lowestoft spans postcode districts NR32, NR33 in Suffolk. If you are just outside Lowestoft, we also cover Great Yarmouth (9 miles) and Norwich (22 miles).
Suffolk is one of the parts of the UK where clay soils are most likely to move with the seasons. Ground movement here is more often linked to soils, drains and trees than to mining. Typical buildings in Suffolk: Timber-framed and flint cottages, Victorian terraces in Ipswich and Lowestoft, and post-war estates.
What to expect when we carry out floor joist repairs
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.

Repair options we may recommend
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
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
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
What is the price of floor joist repairs in Lowestoft?
Guide prices for floor joist repairs in Lowestoft start from about £260 per joist, including VAT, on East of England rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.
Do you carry out floor joist repairs in Lowestoft?
Yes. We take enquiries from across Lowestoft, including NR32, NR33, and from nearby places such as Great Yarmouth and Norwich. Send photos for a free initial view and we will tell you what happens next.
Does the ground around Lowestoft cause cracking?
Much of Suffolk is chalky boulder clay, with London Clay around Ipswich and Felixstowe and sandier ground in the Breckland and on the coast. The clay areas are prone to seasonal shrinkage near trees. 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.
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.
