Window and lintels

Question

If the windows and lintels need to be replaced on a 4 bed detached property, how much would that likely cost? Our Level 3 survey has flagged some movement on the property which has caused the lintels to shift. Any help is appreciated! Thank you.

It can vary quite a bit depending on how many windows are affected and how much movement there has been, but just to give you a rough idea:

Replacing a lintel above a window is usually somewhere in the region of £600–£2,000 per opening, depending on the size of the opening, the type of lintel required, and whether access equipment or scaffolding is needed.

On a 4-bed detached property, if several windows need new lintels and there’s some brickwork that needs to be taken out and rebuilt, the total could roughly fall anywhere between £5,000 and £15,000+.

The work normally involves supporting the brickwork above the opening, removing the old lintel, installing a new steel or concrete lintel, and then making good the brickwork and internal finishes.

Since your Level 3 survey has flagged movement, it would also be sensible to have a structural engineer take a look first, just to confirm the cause and make sure the correct type of lintel and repair is carried out.

If a Level 3 survey has identified movement affecting the lintels, the first thing would normally be establishing whether the movement is historic or ongoing before replacing anything, as in some cases the issue is limited to failed or undersized lintels, while in others there may be wider structural movement that needs addressing first. In terms of cost, replacing windows and lintels across a 4-bedroom detached house can vary significantly depending on the number of openings, access, scaffold requirements, wall construction, and the type of replacement windows being installed. As a rough guide, full window replacement on a detached property is often somewhere around £6,000–£12,000+ for standard uPVC systems, while lintel replacement commonly ranges from around £650–£1,500 per opening depending on the size and structural complexity. Where movement is involved, costs can increase further because the work may require temporary structural support, brickwork repairs, crack stitching, internal making good, structural engineer involvement, and additional scaffold access. If multiple lintels are affected throughout the property, it would not be unusual for the overall project cost to move well beyond basic window replacement figures. Before committing to works, it is usually worth having a structural engineer properly assess the cause of the movement so you know whether replacing the lintels alone will resolve the issue.

Personally I price a minimum fee of 500£ per lintel, might go up depending on complexity!

John · Answer

depending on what type of lintelsthey are and wht the span is really, but normally say a lintael costs around £100 then labour on top, a good builder could probably replace 3/4 lintales in a day at a cost £250 a day

Unfortunately,It would be difficult to estimate a price as there could be so many different issues that would mean that without a proper survey any estimate would be a vague guess at best.

Tim · Answer

All depends on size of lintels and window, I did one the other day £1740

Charles · Answer

Replacing all windows on a 4-bed detached can cost £6,500–£11,000+, and lintel replacement for shifted openings is roughly £650–£1,200 per opening, depending on complexity. Always get a structural engineer for lintels.

The cost can vary quite a lot depending on how many windows and lintels are affected, the type of lintels required, access to the property, and whether any structural movement is still ongoing.

If movement has been flagged in the Level 3 survey, I would strongly recommend having the property properly assessed first before carrying out replacement works, as it is important to understand what has caused the movement and whether it has stabilised.

The best option would be to arrange a site visit so the condition of the lintels and surrounding brickwork can be inspected properly before providing an accurate quotation.
