Lime Mortar Repointing in St Albans
Repointing is the most vital maintenance task for any period property. For houses built before the 1920s in St Albans, the use of authentic lime mortar is not just a stylistic choice—it is a structural necessity. Heritage Brickworks are unparalleled specialists in traditional lime mortar repointing, protecting your home from damp while restoring its original, historic charm.
The Danger of Cement on Victorian Bricks
Much of St Albans' beautiful Victorian and Edwardian housing stock has suffered from inappropriate 20th-century repairs using hard Portland cement. Because cement is harder and less porous than the old soft red bricks, moisture becomes trapped inside the brick face, freezing in winter and causing the brick faces to shatter (spall). We meticulously rake out this damaging cement using hand tools to avoid further brick damage, replacing it with highly breathable lime mortar.
Authentic Finishes and Color Matching
Lime mortar allows a building to naturally manage moisture. We mix our own lime putties and hydraulic limes, carefully selecting local sands and aggregates to match the exact color, texture, and profile of your property's original pointing. Whether your home requires a traditional flush joint, a neat weather-struck finish, or a specialized penny-roll joint, our finish is indistinguishable from masterful 19th-century masonry.

Frequently Asked Questions
How long does lime mortar repointing last?
When applied correctly by specialists, traditional lime mortar pointing can easily last 50 to 100 years, depending on the wall's exposure to extreme weather.
Is lime mortar more expensive than cement?
The materials themselves are slightly more expensive, and the process of properly raking out old joints and carefully applying lime is highly skilled, labor-intensive work. However, investing in lime mortar prevents catastrophic brick damage and severe internal damp issues that are vastly more expensive to fix.
