Window Lintel Repair Kit (Grout)

An ideal kit that contains the materials you need to carry out a window lintel repair

This is a window lintel repair kit for repairs to a lintel that is failing or needs reinforcement after the installation of UPVC windows, usually where a timber or metal window frame has provided structural support. For instructions on how this can be used, please see the attached video.

Window Lintel Repair Kit (Grout based)

The lintel repair kit contains enough material to carry out the installation of a retro fitted lintel into a 3.6M window opening.

Contains

• x1 6.5kg Strucsol HS Grout
• x2 coils of 6mm x 10 metres helical bar (also known as helibars or helicoils) - bearing in mind that for lintel repair it should be twin wire in the slot.
• x1 Strucsol Grout Gun with pointing nozzles including the stainless steel pointing nozzle to make grout application much cleaner and easier
• x1 Grout Whisk

What is the difference between grout and resin for window lintel repairs?

Put simply, it depends on the urgency of the repairs you're carrying out.

If the brickwork around the lintel (or lack of lintel) is not at immediate risk of collapsing, use this grout kit - it has an initial set time of 1 hour (enough to take the initial structure load) and a full cure time of 14 days. It gives you more working time to complete the repair in a cleaner manner and is well suited to lintel repair where a controlled set is preferred.

If the brickwork around the lintel is fragile and you need immediate strength from the repair, use our resin based kit - but keep in mind that the resin sets in 10 minutes (quicker on warmer days), so you will need to be relatively quick at carrying out the repair.

Cracked brickwork and window lintel replacement

When cracked brickwork appears above a window, it can be a sign that the existing lintel has failed or needs reinforcement. This kit is designed for window lintel replacement and window lintel repair where a grout-based solution is suitable and a slower set time is beneficial.

The polymer-modified grout helps provide high strength, superior adhesion and a non-shrink finish for structural masonry repair work. Combined with helical bars, it supports lintel repair work on windows and other masonry openings where controlled application is important.

It is a practical choice for builders, contractors, homeowners and structural repair professionals looking for a reliable lintel repair kit for masonry and brickwork repairs.

For a cleaner application, use the supplied grout gun and stainless steel pointing nozzle to apply the grout into the prepared slot. The kit is intended for use where there is time to complete the repair carefully rather than where immediate strength is required.

Because the grout has an initial set time of around 1 hour and a full cure time of 14 days, it is suited to projects where you want more working time and a neat finish. It is commonly considered alongside other window lintels and lintel replacement systems when assessing how to repair lintels over windows.

If you are comparing options for a concrete lintel repair kit or a window grout solution, this grout-based kit offers a controlled alternative to a fast-setting resin repair. Always match the repair method to the condition of the brickwork and the urgency of the job.
