Planning lintel replacement in Glasgow

Lintel replacement is the removal of a failed beam above a window, door or other opening and its replacement with a new lintel specified by a structural engineer. The masonry above is held on temporary supports while the old lintel comes out, the new one is bedded level on sound bearings, and the brickwork and plaster around it are rebuilt and made good.

Lintel replacement is one of the most common structural jobs in homes across Glasgow. We cover the city and its surrounding districts. Every job starts with a survey visit, then calculations from a structural engineer, so the steel suits the house in front of us rather than a rule of thumb.

Things to plan for

  • Diagonal cracks that start at the top corners of a window and step up through the mortar joints are a classic sign of a lintel problem. Movement elsewhere in a house can cause similar cracks, so the cause is confirmed on site before anything is replaced.
  • The replacement is specified by a structural engineer, who looks at the opening width, the wall construction and what the lintel carries, such as floor joists, a bay roof or a gable. Solid walls and cavity walls usually call for different lintel types.
  • Cables for outside lights, burglar alarms and doorbells often run just above window and door heads. These are noted at the survey and made safe by an electrician before the brickwork is opened up, then reinstated afterwards.
  • Ground-floor lintels can usually be replaced from the ground with props alone. Openings on upper floors need scaffolding or a tower, which adds time and cost but also gives a safe, stable platform for rebuilding the brickwork neatly.
  • Concrete lintels fail when the steel reinforcement inside rusts and swells, pushing off the concrete face. Rust staining, flaking edges and exposed bars are the warning signs, and once that process is well under way an engineer will often recommend replacement over patching.

Four stages, one team

  1. Free visit

    A short visit to Glasgow to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building warrant

    A building warrant is applied for from Glasgow City Council, and work starts only once the warrant has been granted.

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

How much should I budget in Glasgow?

As a guide, budget £360–£1,090 per lintel including VAT for lintel replacement in Glasgow, based on published UK cost guides adjusted for prices in Scotland (-9%).

Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.

Building control and neighbours in Glasgow

In Scotland, structural alterations need a building warrant under the Building (Scotland) Act 2003, and work must not start until the warrant is granted. For Glasgow, warrants are handled by Glasgow City Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.

Scotland has no Party Wall Act. Work affecting a shared wall is governed by your title deeds and the general law, and in flats by the Tenements (Scotland) Act 2004, so it is sensible to agree the work with neighbours in writing before starting.

Lintel replacement in Glasgow: your questions

How much does lintel replacement cost in Glasgow?

As a guide, budget £360–£1,090 per lintel including VAT for lintel replacement in Glasgow, based on published UK cost guides adjusted for prices in Scotland (-9%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

Who approves lintel replacement in Glasgow?

Structural work in Glasgow needs a building warrant from Glasgow City Council, granted before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.

What type of lintel will be fitted?

The engineer decides, based on the opening width, the wall construction and the load above. Steel lintels are common in cavity walls, while solid walls or wide openings may suit a different type or a steel section. We fit what the specification calls for rather than a one-size option.

How long does lintel replacement take?

Most single openings take one to two working days on site, covering propping, removing the old lintel, fitting the new one and rebuilding the brickwork. Upper-floor lintels needing scaffolding, wide bay windows, and jobs where bricks must be sourced to match can all take longer.

Can a lintel be replaced without removing the window?

Often, yes. The brickwork above is propped, the old lintel is taken out and the new one fitted while the frame stays in place under protection. If the frame has been carrying weight because the old lintel sagged, it may need easing or adjusting once the new lintel is in.

Do I need scaffolding to replace a lintel?

For ground-floor windows and doors, usually not, as props and a stable platform from the ground are enough. First-floor and higher openings normally need scaffolding or a tower so the brickwork can be rebuilt safely, and that cost appears as its own line in the quote.

Do I need a party wall agreement for lintel replacement in Glasgow?

There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it starts.
