Damp proofing in Burnham-on-Sea
Burnham-on-Sea sits low and flat on the Somerset Levels, right on the estuary. A high water table, clay ground and salt-laden weather make it one of the few places where rising damp really is as common as people think.
Why Burnham is different
Most of the North Somerset patch sits on higher, free-draining ground where genuine rising damp is relatively rare. Burnham-on-Sea and the Levels around it are the exception. The land is barely above sea level, the subsoil is clay, and the water table is high year-round. In an older property whose slate or bitumen damp-proof course has failed, or that never had one, moisture will move up the wall base, and rising damp treatment is genuinely the right answer.
We still don’t assume. A moisture profile and salt analysis confirm rising damp and rule out a leaking service pipe or bridged DPC first.
Solid floors
Burnham has a lot of inter-war and post-war bungalows, popular with retirees, built with solid concrete floors. Where the floor’s damp-proof membrane has broken down or was never fitted, you get damp coming up through the slab, lifting floor coverings and tracking to the base of walls. This needs a floor solution, not just wall treatment.
Estuary weather and timber
West-facing elevations take salt-laden wind off the estuary, weathering render and pointing and driving penetrating damp inward. Combined with the high ground water, damp floor and wall timbers are common, so wet rot and woodworm checks are part of most surveys here.
What we treat in Burnham-on-Sea
Damp proofing
Diagnosis and treatment of rising damp, penetrating damp and water ingress. Root cause first, then the right fix.
Rising damp treatment
Chemical damp-proof course injection and waterproof replastering, only where rising damp is actually confirmed.
Penetrating damp
Finding and fixing water getting in through walls, roofs and around openings, including high-level defects via drone survey.
Timber treatment & rot
Dry rot eradication, wet rot repair and structural timber treatment, with the damp source dealt with too.
Woodworm treatment
Identifying active woodworm and treating every accessible timber with Biokil Crown approved products.
Damp & timber surveys
Independent surveys using calibrated moisture meters, FLIR thermal imaging and drone roof inspection.

Common questions about damp proofing in Burnham-on-Sea
Is rising damp genuinely more common in Burnham than elsewhere?
Yes. Burnham-on-Sea sits low on the Levels with a high water table and clay subsoil, so where a wall has no working damp-proof course, genuine rising damp is a real and frequent finding, not the over-diagnosis it often is on higher, drier ground. We still confirm it with a moisture profile before treating.
Our bungalow has a damp solid concrete floor. Can that be fixed?
Often yes. Many Burnham bungalows have concrete floors with a failed or absent damp-proof membrane. Options range from a surface damp-proof membrane system under a new floor finish to a full dig-out, depending on levels and use. We assess it as part of a survey.
Do you cover Highbridge and the surrounding Levels villages?
Yes, Highbridge, Brean, Berrow, East Huntspith, Mark and the villages out towards the Levels all share the same low-lying, high-water-table conditions.
