Do You Need a Lintel Repaired or Replaced?

Lintels are structural supports installed above windows, doors and other openings to carry the weight of the brickwork or structure above.

Over time, lintels can deteriorate due to corrosion, cracking, moisture damage or inadequate structural support. When a lintel begins to fail, it can cause visible cracking in surrounding brickwork, movement above openings and problems with windows or doors.

Common signs of lintel failure include:

  • Diagonal or stepped cracks in brickwork above windows and doors.

  • Cracked, crumbling or damaged concrete lintels.

  • Rusting or corrosion of steel lintels.

  • Sagging or movement in brickwork above an opening.

  • Windows or doors becoming difficult to open or close.

  • Gaps appearing between window frames and surrounding masonry.

These symptoms do not always indicate lintel failure, so identifying the underlying cause is important before carrying out repairs.

If you are concerned about a damaged or failing lintel, Wall Away can arrange a site survey to assess the problem and advise on the next steps.

Expert Lintel Repair & Replacement Services

Lintel Repairs

Not every damaged lintel requires complete replacement. Depending on its condition and the cause of the problem, it may be possible to repair or reinforce the existing structure. Our team can assess the lintel and surrounding masonry to establish whether a suitable repair is possible or whether replacement is the safer long-term solution.

Lintel Replacement

Where an existing lintel has failed, deteriorated or can no longer provide adequate support, a replacement may be necessary. Wall Away carries out structural lintel replacements, including the safe temporary support of the masonry above, removal of the existing lintel and installation of a suitable replacement.

Steel & Concrete Lintel Installation

We install steel and concrete lintels to support brickwork and structural loads above windows, doors and other openings. The correct lintel type and specification will depend on the construction of your property, the width of the opening and the weight being supported.

Window & Door Lintel Replacement

Cracking above windows and external doors can sometimes indicate that an existing lintel is damaged, inadequate or missing. We assess the structural support above the opening and carry out the necessary lintel replacement or installation work to restore adequate support.

How Much Does Lintel Replacement Cost?

The cost of lintel repair or replacement varies depending on the type of lintel, the size of the opening and the extent of the structural work required.

Replacing a straightforward lintel above a window will generally cost less than a complex installation involving extensive brickwork repairs, difficult access or additional structural reinforcement.

The main factors affecting lintel replacement costs include:

  • Lintel type: Steel, concrete and other structural lintels have different material and installation requirements.

  • Opening size: Wider openings may require larger or more substantial structural supports.

  • Access: Upper-floor windows and difficult-to-reach locations may require scaffolding.

  • Existing damage: Cracked or displaced brickwork may need additional repairs.

  • Structural requirements: Engineering calculations and Building Control involvement may be necessary.

At Wall Away, we provide a free site survey and quotation so you can understand the work required and the associated costs before proceeding.

Specialists in Structural Lintel Replacement

Replacing a lintel involves more than simply removing an old beam and fitting a new one. The surrounding structure must be properly supported throughout the work, and the replacement lintel must be suitable for the loads it carries.

At Wall Away, structural alterations are our speciality. Alongside lintel repairs and replacements, we regularly undertake Load Bearing Wall Removals, RSJ Installations and Structural Openings.

Our experience working with load-bearing structures means we understand the importance of careful planning, temporary support and correct installation.

We aim to provide a straightforward service, from assessing the existing lintel to completing the necessary structural work with minimal disruption to your home.

Our Lintel Replacement Process

1. Free Site Survey & Quote

We begin by assessing the existing lintel, surrounding brickwork and any visible signs of structural movement. This helps us identify the likely cause of the problem and determine whether repair or replacement is appropriate.

2. Structural Assessment & Planning

Where necessary, we arrange structural calculations and establish the correct specification for the replacement lintel. We also identify any Building Regulations requirements before work begins.

3. Safe Lintel Removal & Installation

The structure above the opening is temporarily supported as required before the damaged lintel is carefully removed. We then install the replacement lintel and complete the associated structural work.

4. Completion & Inspection

Once installed, we complete the agreed making-good works and arrange any necessary Building Control inspections to ensure the structural alterations meet the required standards.

  • Some lintels can be repaired or reinforced, depending on the extent of the damage and their structural condition. However, where a lintel is severely cracked, corroded or no longer capable of supporting the load above, replacement is often the most appropriate solution. A site assessment will help establish which option is suitable.

  • Common signs of a failing window lintel include diagonal or stepped cracks above the window, sagging brickwork, visible corrosion and gaps between the window frame and surrounding masonry. These symptoms can also have other causes, so a professional assessment is recommended.

  • Window lintel replacement costs depend on the size and type of lintel, the accessibility of the opening and whether additional brickwork repairs are required. Upper-floor windows may also require scaffolding. Wall Away provides free site surveys and quotations to help you understand the cost of your particular project.

  • Yes, a damaged concrete lintel can often be replaced with a suitable steel lintel. However, the replacement must be correctly specified for the opening, wall construction and structural loads. A structural assessment will determine the most appropriate solution.

  • Building Regulations approval may be required when replacing or altering a structural lintel, particularly where the work affects a load-bearing element. A straightforward like-for-like repair may have different requirements. Wall Away can advise on the relevant requirements and coordinate Building Control involvement where necessary.

  • A straightforward lintel replacement may be completed within one or two working days once the necessary preparations are in place. More complex projects involving scaffolding, structural calculations or extensive masonry repairs can take longer. We will discuss the expected timescale following your site assessment.

  • In some cases, a lintel can be replaced while the existing window remains in place. However, this depends on the construction of the opening, the condition of the surrounding brickwork and the support required during installation. We will assess whether the window can safely remain in position before work begins.

  • No. Cracks above windows can be caused by several issues, including thermal movement, settlement, inadequate support or deterioration of the surrounding masonry. A failing lintel is one possible cause, but it is important to identify the underlying problem before deciding on repairs.

  • Lintel replacement involves supporting the weight of the structure above an opening. Incorrect removal or installation can cause serious structural damage. We strongly recommend using experienced structural specialists rather than attempting the work yourself.
