About our lintel replacement service in Dunstable
We carry out lintel replacement in Dunstable, covering the LU5 and LU6 postcode districts. Dunstable is around 4.5 miles from Luton, and we cover both. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We survey the opening, arrange the engineer's specification and building control, prop the wall, swap the lintel and rebuild the masonry and plaster around it. Your quote is written and itemised, and it covers matching the bricks and mortar as closely as the existing wall allows.
Key points for your project
- Replacing a structural lintel is generally treated as building work, so approval is in place before it starts. In England, Wales and Northern Ireland that means building control, and in Scotland a building warrant is needed before structural work begins.
- While the old lintel is out, the brickwork above sits on adjustable steel props with needles or masonry prop heads fixed through the mortar joints. The props stand on boards or spreaders so their load is shared across the ground or floor beneath.
- 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.
- Bay windows often rely on a timber beam, sometimes called a bressummer, across the front of the bay. When it rots, the bay roof and the brickwork over it can drop, and the engineer may specify a steel replacement instead.
- 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.
Four stages, one team
Free visit
A short visit to Dunstable to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to Central Bedfordshire Council, so approval is in place before the wall is touched.
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.

Approvals in Dunstable
Structural openings in English homes need building regulations approval before work starts. Central Bedfordshire Council can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Local questions answered
Do you cover Dunstable for lintel replacement?
Yes. We carry out lintel replacement in Dunstable and the LU5 and LU6 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
What happens at the survey visit in Dunstable?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Can a timber lintel in an old house be replaced with steel or concrete?
Yes, where the engineer is satisfied it suits the wall. Timber lintels in older solid-walled homes are often swapped for a steel or concrete alternative that will not rot. The engineer considers how the wall is built, and where lime mortar is present the rebuild uses a compatible mortar.
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.
How do I know if my lintel needs replacing?
Look for diagonal cracks rising from the top corners of a window or door, brick courses that dip over the opening, rust staining or flaking on a concrete lintel, and frames that have started to stick. Any of these is worth having checked, as the cause needs confirming on site before a replacement is planned.
