Which repair method suits a home in Thurso?

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

What happens when we carry out floor joist repairs in Thurso?

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.
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 Thurso: questions and answers

How much should I budget for floor joist repairs in Thurso?

Guide prices for floor joist repairs in Thurso 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.

Why do houses in Highland and Moray crack?

The Highlands and Moray are hard rock and glacial deposits with little shrinkable clay; exposure, steep sites and older stone buildings drive most structural work. 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.

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.
