Drying Buildings

Controlled drying after flood, leak or fire-fighting water.

After a flood or major leak, the visible water is gone within days. The water inside the walls and floors is a different matter.

Why drying takes longer than it looks

Thick masonry walls and solid floors absorb large quantities of water and release it slowly. A building can look and feel dry while its fabric remains saturated at depth, which is why redecorating or refitting too early so often ends in renewed dampness, blown plaster and decayed timber.

Controlled drying

Effective drying balances heat, ventilation and dehumidification, adjusted to the construction. Aggressive forced drying can damage traditional fabric (cracking, salt damage and distortion), so the regime must suit the building. Throughout, drying should be tracked with moisture measurement and environmental monitoring rather than assumed from elapsed time.

Verified, then repaired

We establish drying strategies, monitor progress with measured evidence, and confirm when the fabric is genuinely ready for reinstatement. In insurance work this protects the owner twice over: the repair is not built on wet fabric, and the drying period is justified by data. See our insurance reinstatement services.
