Lintel Repairs, why change your lintels when you could have them repaired by our experts!
Lintel repairs are common on period properties, cracking above and below the windows and doors, dropping and displacement in a window arch, these are common issues of lintel failure. The wall above a door or window head should be supported. Historically, this was by way of timber lintels and brick arches, either flat or with a slight curve. Most recently these lintels are formed from concrete or concealed metal upon which the brick or block walling is carried. Here at London Structural repairs we can repair your lintels at a fraction for a fraction of the cost of replacing them.
Have you recently had your windows changed? are your Lintels in a solid and safe condition
Timber can decay through rot or woodworm and subsequently crush. Timber lintels can also sag through age, resulting in movement within the brickwork above. The outline of cracking will form a triangle rising from either end of the lintel to an apex.
In some instances there is no lintel but the support is provided by a solid timber framed window. When these have to be replaced by newer UPVC windows, damage can occur if a new lintel is not inserted, as the lighter modern windows are unable to support the weight of the brickwork.

Concrete lintels need routine maintenance as well as masonry lintels
Concrete lintels are either pre-cast or are cast on site. Both will be reinforced with steel. If the reinforcement is missing or inadequate, or if a pre-cast lintel is placed the wrong way up then deflection in the lintel will occur giving rise to triangulated cracking above.
The reinforcement within concrete lintels may be of mild steel, which can corrode if exposed to moisture so it is important to keep up with periodic routine painting of your lintels.
Corrosion is an expansive force which can cause the concrete to spall forcing the lintel to fail and deflect with cracking above.
Metal lintels or beams can also corrode. If the corrosion is severe and the load fail ability is impaired then sagging may occur. The same triangulated pattern of cracking will develop above the lintel or beam.
Total collapse of a lintel is not unknown and this will cause the wall above to fall away leaving a triangulated void
Good maintenance could preserve the structural integrity of your lintels and save you money
Weathering of the mortar joints between bricks to a brick arch can cause a loss of adhesion between the bricks and slipping. This will result in a drop in the brickwork supported above and a triangle of displacement so it is important to periodically check the condition of the mortar joints for any sign of deterioration.
