A heritage brick specialist combines knowledge of traditional brickmaking, brickwork craft and conservation principles to source, match and lay the correct bricks for historic building repair. Modern machine-made bricks are produced to metric dimensions and fired to uniform density - they are visually and physically incompatible with the soft, handmade imperial bricks used in Georgian, Victorian and earlier buildings. A heritage brick specialist can identify matching clay sources, advise on reclaimed brick suppliers and carry out the gauged and specialist brickwork skills required for high-quality heritage repair.
What they do
- Identify and source matching bricks for historic building repair
- Advise on handmade versus reclaimed brick for conservation work
- Carry out specialist gauged brickwork for arches and complex details
- Lay heritage brickwork in appropriate lime mortar mixes
- Produce brick sampling and matching reports for conservation officers
- Specify heritage brickwork for listed building consent applications
- Advise on polychrome brickwork restoration
- Source specialist imperial-format bricks from heritage manufacturers
When you need one
A heritage brick specialist is needed when standard modern bricks cannot match the character of historic brickwork on a listed or conservation area building.
Typical costs (UK, 2025)
| Item / Service | Typical cost |
|---|---|
| Handmade imperial brick (per brick) | £1.50 - £4.00 |
| Reclaimed matching brick (per brick) | £0.80 - £3.00 |
| Specialist gauged brickwork - arches etc (per day) | £300 - £500 |
| Brick matching and sampling service | £200 - £500 |
| Heritage brickwork specification advice | £300 - £700 |
| Bricklaying in heritage context (per day) | £250 - £400 |
Lead times for specialist handmade bricks can be 3-6 months. For small repairs, reclaimed brick specialists and salvage yards are often faster and can provide well-matched material. Always factor in lime mortar specification costs separately.
Qualifications to look for
SPAB publishes guidance on brick repair and lime mortar for old buildings. Heritage brick specialists who have completed SPAB training or follow SPAB principles demonstrate a sound understanding of conservation brickwork.
Specialist heritage bricklayers who are Guild members have demonstrated craft competence and are vetted for quality of work.
Frequently asked questions
What is the difference between imperial and metric bricks?
Imperial bricks (pre-1970s) are 9x4.5x3 inches (228x114x76mm). Metric bricks (post-1970) are 215x102.5x65mm - they are smaller. Using metric bricks in a wall of imperial bricks produces a visible size mismatch that is unacceptable on listed buildings.
Where do heritage brickmakers source clay?
Traditional brickmakers typically use local clay from historic brick pits if still available, or clays matched by geological analysis to produce bricks with the right colour, texture and firing characteristics. Some historic brick clays are still commercially available from traditional brick pits.
Can I use reclaimed bricks instead of new handmade?
Yes, and reclaimed bricks from demolished buildings of the same age and locality are often the best match for colour and texture. Check for frost damage, spalling or soft faces before using reclaimed bricks in exposed locations, as damaged reclaimed bricks will deteriorate rapidly.
