Why does the ground in Renfrewshire and Inverclyde matter for lintel replacement?
Postcode districts PA5 cover Johnstone, a Renfrewshire and Inverclyde town of about 16,000 people. Nearby, we also cover Paisley (3 miles), Barrhead (5 miles) and Renfrew (6 miles).
Clay shrinkage is less of a concern in Renfrewshire and Inverclyde, so other causes such as drains, poor footings or older walls are checked first. Parts of Renfrewshire and Inverclyde lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause. Across Renfrewshire and Inverclyde, most homes are sandstone tenements, villas in East Renfrewshire, and post-war estates.
What to expect when we carry out lintel replacement
Specify the replacement
We confirm the lintel type, length and bearing needed. For wide openings, bays or walls with unusual loads, an engineer may specify it, and where the repair needs an engineer’s design or sign-off we can arrange one.
Support the wall
Props or needles are set so the brickwork above carries no load on the old lintel. Windows are protected or temporarily removed where the work demands it, and the room inside is sheeted against dust.
Remove and replace
Brickwork is carefully taken out above the lintel, the old lintel removed and the new one bedded level on full bearings. A cavity tray goes in where relevant, then the brickwork above is relaid.

Repair options we may recommend
Propping and needling
Adjustable props carry the wall above while the old lintel comes out. For heavier walls, short steel needles are passed through holes cut above the opening and propped on both sides, taking the load off the lintel completely. The supports stay until the new work has set.
Best for: Openings with heavy walls, upper floors or bay windows above
Replacement with a cavity tray
A damp-proof membrane is laid over the new lintel with stop ends and weep holes, so water running down the cavity is directed out rather than into the house. Many older lintels were installed without one, which is often why they failed.
Best for: Cavity walls with damp above windows
Rules for lintel replacement in Scotland
In Scotland, underpinning and other structural alterations generally need a building warrant from the council’s building standards service before work starts, and a completion certificate at the end; small like-for-like repairs often do not. There is no Party Wall Act in Scotland; shared walls are covered by title deeds and, for flats, the Tenements (Scotland) Act 2004.
Your lintel replacement questions
How much should I budget for lintel replacement in Johnstone?
Guide prices for lintel replacement in Johnstone start from about £710 per opening, including VAT, on Scotland 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 Johnstone?
Yes, Johnstone is covered, along with postcode districts PA5. We also cover nearby Paisley and Barrhead.
Why do houses in Renfrewshire and Inverclyde crack?
Renfrewshire has glacial till and Clyde alluvium with coal workings recorded in parts, while Inverclyde's towns climb steep slopes above the Clyde with many retaining walls. Only an investigation can say why a particular building has moved.
What is a cavity tray and do I need one?
A cavity tray is a damp-proof membrane above a lintel that catches water running down inside a cavity wall and sends it out through weep holes. If your wall is cavity construction and the original lintel had no tray, fitting one with the new lintel is usually sensible.
Do I need building regulations approval to replace a lintel?
In England and Wales, replacing a lintel is structural work and building control will usually need to approve it. Rules differ in Scotland and Northern Ireland. We deal with building control where the work needs it, and include the cost in the quote.
