Shoreham-by-Sea damp proofing beside the Adur and out on the Beach
The Brighton Plasterer provides damp proofing across Shoreham-by-Sea and BN43, from the riverside streets by the Adur to Shoreham Beach and Old Shoreham. James establishes whether the moisture is ground water, wind-driven rain or condensation, then treats it with an injected course, tanking, membrane or breathable re-plaster.
Damp Proofing in Shoreham-by-Sea, and what is different about it
Shoreham gives damp three different front doors. Along the Adur the water table is high and tidal, so ground moisture never really drops away. Out on the Beach the houses sit on shingle and take salt spray head on. Inland at Old Shoreham the fabric is soft brick, flint and lime, where the wrong repair does more harm than the damp did.
On the riverside streets and around Kingston Buci, persistent ground moisture means that anything bridging the base of a wall shows up quickly. A patio laid over the old slate course, a border built up against the brickwork, or a garage floor poured against the house will all produce a damp band inside within a season or two. On the Beach the mechanism is different again: salt spray reaches the walls directly rather than as diluted sea air, and it finds the mixed backgrounds of contemporary houses where blockwork meets insulation meets timber.
The survey has to answer a simple question: is water arriving from the ground, from the weather, or from the air inside the room? Readings up the wall settle the first. Watching how the damp responds to a wet week settles the second. The third shows itself in the pattern, on cold surfaces and in rooms that are shut up. On the Beach James also checks the render for cracks at background junctions and around the big window openings, because a crack no wider than a hair will carry a surprising amount of driven rain.
Where the ground is the source near the Adur, the cheapest lasting fix is often outside: drop the level, form a gap at the base of the wall and get the surface water away. Where the original course really has gone, it is injected and the wall re-plastered in a salt-resistant renovating system. A room below ground level being used as habitable space gets tanking or a cavity drain membrane instead. In Old Shoreham the answer stays lime, because sealing soft brick and flint behind a hard finish pushes moisture into the timber and the mortar.

What Shoreham-by-Sea needs watching for
Tidal ground allowed for
Riverside plots near the Adur hold moisture that inland streets never see, so the base of the wall and the surface drainage get as much attention as the plaster does.
Hairline render cracks found
On the Beach a crack at a background junction carries a lot of driven rain. James inspects the joints and reveals before deciding that anything internal is needed.
Modern backgrounds identified
Blockwork, insulation and timber frame sit side by side in the newer Beach houses, and each takes a different repair. What is behind the render is established first.

How the job runs
Step by step in Shoreham-by-Sea
The order below is how a damp proofing job actually runs on the kind of property Shoreham-by-Sea is made of. For the full method and the materials behind it, see the damp proofing page.
01Moisture profile taken
Readings are recorded up and along each wet wall so the shape of the problem is on paper, rather than a judgement made from a single spot check.
02Ground and render inspected
Levels, patios, gullies and the base of the wall are checked outside, along with render cracks, reveals and seals on the exposed Beach elevations.
03Water stopped at source
Levels are dropped, cracks are cut out and repaired, or an injected course and membrane go in where the survey genuinely justifies them.
04Breathable or salt-resistant finish
Old Shoreham fabric is re-plastered in lime, while contaminated modern walls take a renovating system, both left to dry properly before decorating.
Straight answers
When it is not the right answer here
- Where a patio has been laid over the original damp course, lowering it is the fix and an injection underneath it is not.
- A cracked render on a Beach elevation lets water in faster than any damp course can keep it out.
- Steamy bathrooms in a small riverside cottage produce condensation that ventilation cures and chemicals do not.

Damp Proofing in Shoreham-by-Sea, questions answered
What people in Shoreham-by-Sea ask before booking damp proofing, answered properly rather than in one line.
Does the tidal Adur make damp worse in riverside Shoreham houses?
It raises the background moisture in the ground, which means any defect at the base of a wall shows up faster and dries more slowly than it would inland. It is not a reason to skip diagnosis, but it does explain why small faults matter more here.
How do I tell ground damp from driven rain on Shoreham Beach?
Watch the weather. Rain-driven damp appears or worsens within a day of a strong south-westerly and eases in a settled spell. Ground moisture holds a steadier line near the floor and pays little attention to what the sky is doing.
Can a modern house on Shoreham Beach get damp?
Yes, and it usually gets in through a detail rather than the wall itself. Mixed backgrounds, long uninterrupted elevations and large glazed openings all crack or open up if the joints were not planned, and driven rain finds them straight away.
What is the right damp repair for an Old Shoreham cottage?
Almost always a breathable one. Soft brick, flint and lime mortar have to keep moving moisture, so lime plaster inside and lime pointing outside are the sensible materials. Sealing that fabric behind cement causes decay that shows up a year or two later.
Do you tank rooms below ground level in Shoreham?
Yes, where the space is going to be used properly. Depending on the construction and the intended use, that is either a tanking slurry system or a cavity drain membrane with a drainage channel, and the choice gets discussed before anything is priced.
How long before a re-plastered wall in Shoreham can be painted?
Longer than the plaster alone would suggest, because a wall that has been wet keeps releasing moisture after the new finish is on. Allow weeks rather than days, and use a breathable emulsion first so the drying is not sealed in.
Is a damp survey in Shoreham-by-Sea chargeable?
No. James visits, takes readings, looks at the outside of the property and tells you what he finds, free and with no obligation. There is no call-out fee, and if the answer is that you do not need treatment, that is what you will be told.
Will lowering my patio really stop the damp inside?
If the patio is bridging the damp course, then very often yes. The aim is to get the finished level back below the course with a drained margin at the wall. It is far cheaper than treatment and it removes the cause rather than masking it.
