Pointing and Repointing Otterbourne

Chimney repointing on a standard residential stack in Otterbourne: £250–£550. Larger or period stacks requiring lime mortar: £350–£700. Free survey and written quote. Call 01962 809171.

For Victorian estate and 1970s chalk Otterbourne properties: NHL 3.5 natural hydraulic lime mortar. Standard sand and cement is too hard for period brickwork and causes spalling. For post-war Otterbourne properties: flexible modified cement mortar. We specify the correct mortar for each property at survey.

NHL 3.5 lime repointing on a Otterbourne chimney: 25–40 years in typical conditions. Otterbourne's chalk escarpment wind exposure means exposed chimney stacks here may see slightly shorter intervals than sheltered valley properties.

Visible mortar loss between the brickwork joints, mortar fragments in the guttering below the stack, damp patches on the chimney breast wall, or a roof survey report recommending repointing. We check chimney mortar condition on every Otterbourne survey visit.

Lime mortar repointing cannot proceed in frost — the mortar does not set correctly below 3°C. Most Winchester winter days are above this threshold. We check the 48-hour forecast before booking repointing and will postpone if frost is forecast.

Most residential stacks in Otterbourne can be accessed from a tower scaffold or roof ladder. Taller or more complex stacks require full scaffold. We confirm the access requirement and include any scaffold cost in the written quote.

Repointing replaces mortar in the joints between bricks. Rendering applies a coat of mortar over the entire brick face — appropriate only where the brickwork itself has deteriorated beyond repair. Repointing is always the preferred option where brickwork is sound.

Fresh lime mortar is lighter than weathered mortar and will be visible for 6–18 months before blending. On Otterbourne period properties in conservation areas where visual consistency is required, a full-stack repoint achieves a consistent appearance. We discuss appearance expectations at survey.

Yes — verge pointing (the mortar at gable edges) and chimney repointing can be combined in a single visit where both are failing. This is efficient as scaffold or tower access is already in place. We check verge condition on every Otterbourne survey.

Yes — ridge rebed and chimney repointing are frequently carried out together on Otterbourne properties where both are at end of life. Combining both in a single scaffold erection saves cost. We include both in the written survey report where applicable.
