Repointing — Cost, Lime vs Cement & UK Guide infographic

Repointing — replacing degraded mortar joints between bricks — is one of the most common bricklayer jobs in the UK. Done right, it adds decades to a wall's life. Done wrong (using cement on soft heritage brick), it destroys the wall it was meant to save. This guide covers what repointing costs in 2026, the critical lime vs cement decision, and the install detail.

The single most important rule: hard cement mortar on soft pre-1919 bricks destroys them. Soft lime mortar on modern bricks is fine but more expensive. Choose based on brick, not preference.

What Does the Work Involve?

  • Inspection to confirm need (degraded mortar, missing joints, water ingress).
  • Raking out old mortar to consistent depth (12–25 mm — twice the joint width).
  • Cleaning brick faces and joint void.
  • Mixing appropriate mortar.
  • Pointing joints with weathered finish to shed water.
  • Curing under sheet for 7+ days if cement; longer for lime.

Lime vs Cement — Which to Use

  • Lime mortar: pre-1919 buildings, soft handmade bricks, listed properties, where original mortar was lime.
  • Cement mortar: post-1919 buildings, hard wirecut/engineering bricks, where original mortar was cement.
  • Hybrid (sand:cement:lime): compromise for borderline cases.

How Long Does It Take?

  • 30 m² wall: 3–5 days for raking and pointing.
  • Plus 7–28 days curing time.
  • Larger projects: extend proportionally.

DIY or Professional?

Repointing is moderately DIY-friendly for cement work on flat walls. Lime repointing and heritage work needs specialist experience. Wrong mortar mix causes irreversible damage.

Choosing the Right Tradesperson

  • Confirm experience with the appropriate mortar type.
  • For listed work, hire heritage specialists.
  • Look at past repointing jobs aged 5+ years — joints should look uniform.
  • Get the mortar mix specification in writing.

UK Regulations

  • Listed properties: consent often needed for repointing.
  • Conservation areas may specify acceptable mortar.
  • Building Regs rare for repointing alone.

Common Problems

  • Cement on heritage bricks — bricks crack as mortar is too strong. Irreversible damage.
  • Poor weather joints — flat or recessed joints trap water.
  • Wrong colour mortar — visible from across the street.
  • Raking depth inadequate — new mortar pops out within 2 years.
  • Curing in rain — fresh mortar washes out.

Frequently Asked Questions

How do I know if my brickwork needs repointing?

Joints crumbling, missing in places, water ingress inside the wall. Tap with a coin — sound joints don't flake or dust.

How long does repointing last?

Cement: 30–50 years. Lime: 50–100 years.

Can I just repoint the damaged areas?

Yes — partial repointing is common. Match the new mortar colour and consistency for invisible joins.

What if my house is mixed (some areas cement, some lime)?

Use lime for the original parts; matching mortar where someone previously used cement. Honest repair acknowledges history.

Why is lime more expensive?

Slower to work, longer curing, fewer skilled trades available. Premium for the skilled time.

Will I notice the difference visually?

Yes if comparing — lime has softer, off-white character. Cement is harder, greyer. Both can be tinted to match.
