Is Fife prone to ground movement?

Rosyth, Fife: about 14,000 residents across postcode districts KY11. Nearby, we also cover Dunfermline (3 miles), Cowdenbeath (6 miles) and Bo'ness (7 miles).

Shrinkable clay is less common in Fife than in south-east England. Historic coal workings are recorded beneath parts of Fife, and a coal mining search is worth checking where movement is unexplained. Housing stock in Fife: Miners' rows, sandstone town houses, tenements and post-war estates.

Repair options we may recommend

Mini-piled bay underpinning

Small piles are installed to depth around or beneath the bay and linked by a reinforced beam or needles that pick up its weight. It suits deeper soft ground and heavy root activity, and the compact rigs fit into a front garden.

Best for: Deep clay, nearby trees, or poor ground below the bay

Traditional underpinning of the bay

The bay footing is excavated in short sections and new mass concrete is placed down to firmer ground below the zone affected by roots and seasons. Because a bay is a short length of wall, the work is compact, but it needs building control approval.

Best for: Active bay movement on firm ground at moderate depth

What to expect when we carry out bay window subsidence repairs

Engineer and checks
Where the cause is unclear, an independent chartered structural engineer inspects, sometimes with a trial pit at the bay and a drain survey. We can arrange the engineer. Monitoring may be suggested if the movement could be seasonal.
Agree the repair
The engineer decides between tie-in repairs and underpinning. We confirm a fixed price in writing once the repair is specified, including scaffolding if needed, the bay window, roof flashing and internal making good.
Carry out the work
Ties are fitted across the junction, or the bay is underpinned in sequence with building control inspecting the dig. The bay window and flashings are checked and eased or resealed where the movement has disturbed them.

Your bay window subsidence repairs questions

What is the price of bay window subsidence repairs in Rosyth?

Do you carry out bay window subsidence repairs in Rosyth?

We do. Rosyth and the surrounding area are covered, including nearby Dunfermline and Cowdenbeath. A free initial assessment from your photos is the first step.

Does the ground around Rosyth cause cracking?

Much of central and west Fife lies on coalfields worked for centuries, with recorded shallow workings around Dunfermline, Cowdenbeath and Kirkcaldy, under a cover of glacial deposits. Only an investigation can say why a particular building has moved.

Is a crack between my bay and the house serious?

It is often not serious, especially if it is old, fine and unchanged for years. A crack that is widening, tapering or matched by sticking windows and a sloping bay floor needs looking at. An engineer’s inspection, sometimes with monitoring, will confirm whether the bay is still moving.

Can a bay be underpinned without underpinning the house?

Yes, underpinning only the bay is common because it is usually the part on shallower footings. The engineer designs the junction so the strengthened bay and the existing house can move slightly without cracking, sometimes with a movement joint or ties.
