Hove damp proofing for lower ground flats and stucco fronts
The Brighton Plasterer handles damp proofing across Hove and BN3, from Brunswick lower ground flats to the Poets Corner terraces. James diagnoses the cause first, then treats it, whether that means an injected damp course, tanking, a breathable lime re-plaster or a repair to a failed external detail.
Damp Proofing in Hove, and what is different about it
Hove damp problems cluster around two things: buildings that sit partly below ground, and buildings that face the Channel. Add the enormous number of houses split into flats, where a bathroom often ended up in a room never meant to hold that much moisture, and most of what James is called to in BN3 falls into a handful of familiar patterns rather than the one everyone fears.
The garden flats under Brunswick Square, Adelaide Crescent and the streets around Palmeira are the classic case. Floors sit below the pavement, the front rooms open onto a light well that fills with leaves, and the vaults under the pavement were never built to stay dry. Further back, the Poets Corner and Aldrington terraces are solid brick with the usual century of raised paths, new patios and rendered plinths trapping water at the base. Along the Kingsway the mechanism changes again: wind-driven rain from the sea pushed through a hairline crack, a perished seal or open pointing.
Telling those apart is mostly a matter of pattern and timing. James maps where the moisture is, how high it goes and whether it changes with the weather, since penetrating damp reacts to rain and a failed course does not. In a converted house he also traces the plumbing and the rainwater goods, because a shared downpipe that nobody owns is a common culprit and a leaking soil stack in a riser will soak a wall for years. Mould in the corner of a bedroom above a cold flat, with dry walls elsewhere, points at ventilation rather than the fabric.
Treatment then follows the diagnosis rather than a catalogue. A below-pavement flat that is going to be lived in properly wants tanking or a cavity drain membrane, taken up high enough to cover the retained ground. A Victorian terrace with a genuinely failed course takes an injection and a salt-resistant re-plaster. A stucco-fronted building in the conservation squares needs the external detail repaired and a lime finish inside, because a hard cement skin on soft brick simply moves the trouble along the wall. Where the fault is a seal on the seafront, the seal gets sorted first.

What Hove needs watching for
Light wells kept clear
A blocked light well or gully outside a Hove garden flat will hold water against the wall all winter. Clearing and draining it often does more than any treatment applied inside.
Communal drainage traced
In a converted house the downpipe or soil stack causing the damp frequently belongs to nobody in particular. James identifies it so the right leaseholder or managing agent can act.
Seafront seals before systems
On the Kingsway and the blocks near it, a perished window seal or open pointing lets rain straight in. That gets repaired before any internal work is worth doing.
How the job runs
Step by step in Hove
The order below is how a damp proofing job actually runs on the kind of property Hove is made of. For the full method and the materials behind it, see the damp proofing page.
01Readings room by room
Moisture is measured across the affected rooms and up each wall, so the height and shape of the problem are recorded rather than guessed at from a stain.
02Outside and below checked
Light wells, gullies, ground levels, pointing, render and window seals are inspected, along with any shared downpipe serving the converted house above.
03Tank, inject or repair
Below-pavement rooms get tanking or a membrane, solid walls with a failed course get an injected damp proof course, and external faults are fixed at source.
04Salt-resistant finish applied
Contaminated plaster is removed and replaced with a renovating system, or with lime on period fabric, then left to dry for weeks rather than days.
Straight answers
When it is not the right answer here
- If the moisture only appears after heavy rain on the seaward side, the fix is the render, pointing or seal, not a damp course.
- A bathroom with no working extractor will keep producing mould whatever is done to the walls around it.
- Damp caused by a leaking communal downpipe belongs to the freeholder, and treating the inside of the flat first wastes money.
Damp Proofing, Hove
Damp Proofing in Hove, questions answered
What people in Hove ask before booking damp proofing, answered properly rather than in one line.
Is the damp in my Hove garden flat rising damp or ground water?
In a room that sits below the pavement it is far more often ground water pressing against a retained wall. Rising damp climbs from a failed course near floor level, while retained ground produces moisture higher up and across a wider area. Readings and levels settle it.
Can a listed Brunswick or Palmeira flat be tanked?
Often yes, but the method has to suit the building and consent may be needed first. A cavity drain membrane is usually gentler on historic fabric than a hard cementitious slurry, because it manages the water instead of trying to seal the wall shut.
Why is there mould behind the wardrobe in my Hove bedroom?
That is a textbook condensation pattern. Furniture against a cold external wall stops air moving, the surface drops below dew point and moisture settles there. Move the furniture off the wall, warm the room a little and get some background ventilation working.
How do I arrange a damp survey for a flat in BN3?
Call or message James on 07999 837148, or use the form on this site. He will take readings, look at the outside of the building and the communal areas where he can, and tell you what he actually finds. There is no charge and no obligation.
What happens to the walls after tanking a lower ground room?
The system is finished with a board or a plaster suited to it, and the room needs time before it is decorated. A tanked wall does not dry the way an ordinary wall does, so James will explain what the finish can take and when.
Who is responsible for a damp wall caused by a shared downpipe?
Usually the freeholder or the managing agent, since communal rainwater goods sit outside an individual lease. James will identify the defect and describe it plainly enough for you to pass on, because treating your own wall while it keeps getting soaked is money thrown away.
Does a stucco front need different damp treatment to a brick one?
Yes. Stucco over soft brick is a breathable arrangement, so a dense cement repair or a plastic paint traps moisture and blows the finish off. Repairs are made in compatible lime-based materials, and the internal plaster is chosen to match.
Will re-plastering on its own stop damp coming back in a Hove conversion?
No, and anyone who says otherwise is selling plaster. Re-plastering makes good after the cause has been dealt with. If the leak, the level or the ventilation has not changed, the new surface will stain again within a year or two.
