Damp proofing in Broadstairs? Get an independent survey first
In Broadstairs, damp proofing is often quoted for flint cottages that never had a damp proof course and seaside walls where salt drives the readings. We are independent surveyors and we sell no treatment, so the report tells you what will actually work.

Why the survey comes before damp proofing in Broadstairs
A free damp survey in Broadstairs is usually a sales visit with a meter. The meter reads high on a wall that is wet for any reason, and on salts in old plaster even when the wall is dry, so a high reading proves very little. An independent survey finds the cause, and only the cause tells you whether damp proofing is the remedy at all.
The Broadstairs quotes we see most often are injection on flint walls and waterproof replastering on seafront walls with salt contamination. Neither addresses cement pointing, rain through render or salt from the sea. On bungalows, damp proofing is sometimes quoted for condensation.
The kinds of damp proofing, and what each one is for
"Damp proofing" covers several different jobs. A chemical damp proof course is a cream or fluid injected into a mortar course to stop moisture rising from the ground. A physical course is a membrane or slate cut into the wall, slower and more disruptive. Tanking is a waterproof coating or render that holds water back on a wall below ground. A drained membrane lets water reach the wall and carries it away to a channel and pump.
Each answers one fault. None of them fixes rain coming through flint, brick and render or brick, a gutter overflowing down a corner, or condensation on a cold wall, and those three account for most of the damp we are asked about in Broadstairs. Replastering is often sold alongside, and on old solid walls the choice of plaster matters as much as anything injected.
Broadstairs walls, and what they actually need
Flint walls need lime pointing and low ground. Seafront walls need sound render, bays and plaster that tolerates salts. Bungalows and post war houses need ventilation and attention to cold spots.
Broadstairs sits on Thanet chalk, cut into bays along the coast, with the cliffs at Kingsgate and Stone Bay. Chalk drains quickly, so damp in cellars and against higher ground arrives with heavy rain and fades. The coastal edge takes the full force of easterly weather and spray.
- Lime repointing on flint and brick cottages
- Render and bay repairs on exposed seafront walls
- Salt tolerant or breathable plaster where old plaster is contaminated
- Ventilation and insulation at cold spots for mould
Broadstairs walls we are asked to look at
The calls we take in Broadstairs fall into three groups. Owners of flint cottages in St Peter's and Reading Street who have been told their walls need a chemical damp proof course. Owners of seafront houses with tide marks and blistered paint on the seaward wall. And owners of bungalows with mould on ceilings and in corners who have been quoted for something called damp proofing that turns out to be a ventilation unit and an injected course together.
In the first group the cause is nearly always cement pointing or raised ground; in the second, rain and salt; in the third, condensation on cold surfaces. None of them is fixed by an injected course, and in the first two the waterproof plaster that usually comes with it makes the wall less able to dry.
What we do is establish which group you are in, with readings and photographs, and set out the proportionate repair. Often that is a few days of lime repointing, or a gutter, or a fan ducted properly to outside. When a genuine damp proof course is needed, the report says that just as clearly.
The signs of a damp proofing job worth paying for
- The contractor can tell you the cause in a sentence and show you the evidence
- The quote mentions what is happening outside the Broadstairs house, not only inside
- Plaster removal is limited to where salts actually are, with a height that matches the readings
- Materials are named and suit the wall, rather than a standard system applied to every house
- The guarantee is insurance backed or otherwise protected, and states exactly what it covers
- Nobody pressed you to sign on the day
Red flags in a damp proofing quote
- A diagnosis of rising damp from a single meter reading
- No mention of anything outside the house
- Injection recommended on internal walls, chimney breasts or walls above ground floor
- A discount that expires today
- Treatment of woodworm or rot in every timber "as a precaution"
- A quote for a Broadstairs period house that would be identical for a 1990s semi
When a damp proof course is the right answer
We are not against damp proofing. We are against it being the default. When a Broadstairs wall has no working course, sits on damp ground and stays wet after the outside has been put right, a damp proof course and suitable replastering is the right job, and the report will say that and specify it.
Our survey fees are published on the prices page and fixed before we visit. Set against a damp proofing job on a Broadstairs house, which typically runs to several times that once plaster removal and making good are included, the survey is small. When it shows that a wall needs a gutter repair rather than an injected course, it pays for itself several times over.
Broadstairs is popular with buyers looking for a quieter seaside town, often buying bungalows or older cottages. Homebuyer reports frequently flag damp, often salt related near the front or cement related on flint. An independent survey before exchange sorts out what is real and what it will cost.
After the survey you have the cause in writing, a list of what needs doing in order, and what does not. If damp proofing is part of it, the report specifies the walls, the height and the finish, so the quotes you collect in Broadstairs are for the same job. If it is not, you have the evidence to say no to the quote you were given.

Damp proofing questions in Broadstairs
Is injection effective in Broadstairs flint walls?
Rarely. A chemical course relies on a continuous mortar bed to spread through, and flint walls are built of irregular nodules in thick lime joints with a rubble core. More to the point, flint cottages in St Peter's and Reading Street are seldom damp because moisture is rising; they are damp because the lime has been replaced with cement, or the garden has risen, or a gutter is failing. Those are the things to fix.
Can damp proofing stop salt damp near the sea?
No. Salt from spray and from years of earlier damp sits in the plaster and draws moisture out of the air, so the wall feels damp and reads high on humid days whatever is injected into its base. Replacing contaminated plaster with a finish that tolerates salts, and keeping rain out of the wall, is what helps.
Our bungalow has mould. Has a firm rightly quoted damp proofing?
Mould on ceilings and in corners is condensation, which a damp proof course cannot affect. It needs less moisture in the air, better extraction, and warmer surfaces, often by improving loft insulation at the eaves. We measure humidity and surface temperatures so the report can say which matters most in your bungalow.
Should we have a survey before buying a Broadstairs bungalow?
Yes. Bungalows can hide flat roof problems over extensions and porches, poorly ventilated sub floors, and cold spots that grow mould. A homebuyer report may flag damp without saying why. An independent survey tells you the cause and the scale of the fix before you commit.
Will you check a damp proofing quote we have already had?
Yes. Send it with your booking. The report will say which parts are supported by what we find, which are not, and whether anything the quote leaves out needs doing first.
Do you carry out any of the work?
No. We survey and report only and take no commission from contractors. That is why the report can say plainly when no damp proofing is needed, which in Broadstairs is often.
Do you carry out damp proofing in Broadstairs?
No. We survey and report only, and we take no commission from contractors. That is what lets the report say a wall does not need damp proofing when it does not. Where it does, the specification is written for you to get like for like quotes.
