Penetrating damp on the Skegness coast

This is an exposed east-facing shore. When weather comes in off the North Sea it arrives as wind-driven rain, hitting seaward walls almost horizontally and testing every joint, sill and flashing. Penetrating damp is the price the coast charges for the view.

How rain gets through a Skegness wall

Penetrating damp is moisture pushed sideways through the building fabric rather than rising from the ground. On this coast the pressure behind it is real: onshore winds are frequent, and the town's famous bracing reputation, sold on railway posters since 1908, describes exactly the weather that loads east-facing elevations with rain and salt spray.

The building stock gives the water plenty of ways in. The tall Victorian and Edwardian former boarding houses near the seafront have three storeys of solid brickwork, and mortar joints repointed in hard cement rather than lime tend to crack and channel water inward. Chimney stacks and parapets take the worst of the exposure. In the interwar and post-war cavity-walled bungalow estates, the usual culprits are debris-bridged cavities, corroded wall ties, blocked weep holes and cracked renders that trap water behind them.

A useful tell: penetrating damp tracks the weather. Patches darken during or shortly after rain on the exposed side of the house, often at high level or around openings, and fade in dry spells. Rising damp does not care about the forecast, and condensation prefers cold corners on sheltered walls.

Finding the route in, then closing it

  1. Trace the entry point The visible patch is rarely under the fault. The specialist follows the moisture path from stain to source: pointing, sills, flashings, gutters and downpipes, render cracks, cavity bridges.
  2. Repair the fabric Repointing in an appropriate mortar, render repair or replacement, flashing and rainwater goods put right, cavities cleared. On salt-loaded seafront walls the repair has to tolerate the coastal environment, not just pass a dry-day inspection.
  3. Let the wall dry and make good Solid brick holds a lot of water. Drying takes weeks to months depending on the season, and internal finishes are made good once the wall is genuinely drying, not before.

Related problems worth ruling out

Long-term rain penetration soaks timber lintels, floor joist ends and window frames, which is how wet rot starts in seafront properties. And a wall chilled by evaporating rainwater becomes a condensation magnet inside, so the two problems often appear together. A proper damp survey separates them before money is spent.
