Damp Proofing Specialists in Greenwich (SE10, SE3)
Professional damp proofing specialists in Greenwich, South East London.
Why Choose All Well for Damp Proofing in Greenwich?
Greenwich's Georgian terraces and Victorian semis, the bulk of the housing stock in SE10 and SE3, were built between roughly 1780 and 1910, well before damp-proof courses became a standard requirement. Solid 9-inch brick walls with no cavity, original slate DPCs that have cracked or been bridged by raised ground levels, and the moisture load from proximity to the Thames make rising and penetrating damp genuinely common here. We work across Greenwich's period housing, from the terraces near Greenwich Park to the semis along the Blackheath border, diagnosing the actual cause before recommending any treatment.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Damp Proofing Tip for Greenwich Homeowners
If you're in a SE10 conservation area or have a listed property near the park, any replastering after damp treatment must use a breathable lime-based system. Standard gypsum plaster traps moisture behind the wall and will fail within a few years. The Royal Borough of Greenwich's conservation team can advise on acceptable finishes if you're unsure.
Damp proofing in Greenwich: what affects the work
We confirm the scope of every job after a free site visit because what's actually causing the damp drives everything else. A single-wall DPC injection in a SE3 Victorian semi is a very different scope to tanking a basement in a Georgian townhouse in SE10.
Rising damp treatment on SE3 and SE10 Victorian and Georgian properties
Chemical DPC injection, silicone cream injected into the mortar course, is the standard fix for a failed or absent damp-proof course. We confirm a fixed price in writing after a free site survey. The scope depends on the number of affected walls, the wall thickness (Georgian solid brick is thicker than later construction), and whether replastering is needed. All our injection treatments use products from suppliers like Safeguard or Sovereign and carry a 20-year written guarantee.
Basement tanking on Greenwich riverside and period properties
Properties near the Thames in SE10 face higher hydrostatic pressure, particularly at ground level and in basements. Tanking, applying a cementitious waterproofing system or installing a cavity drain membrane, is the correct solution where water is penetrating through below-ground walls. It's more involved than DPC injection and carries a 10-year guarantee. The scope depends on basement footprint, existing wall condition, and drainage requirements.
Diagnosing damp in Greenwich's Georgian and Victorian housing stock
The three types of damp, rising, penetrating, and condensation, look similar on a wall but need different fixes. Getting the diagnosis wrong leaves the problem in place. We use calibrated moisture meters and thermal imaging before recommending any treatment.
Rising damp signs in SE10 and SE3 period terraces
In Greenwich's Victorian semis and Georgian terraces, rising damp typically shows as a tide mark up to about a metre high, with white salt deposits (efflorescence) and blown or bubbling plaster at low level. Ground levels in older SE10 streets have often risen over time. Paths, flower beds, or Victorian additions can bridge an otherwise intact DPC. We check external ground levels at the survey because lowering the ground level is sometimes the only fix needed, with no injection required at all.
Penetrating damp and failed pointing on solid brick walls
Georgian and Victorian solid-brick walls in SE10 and SE3 rely on intact mortar joints and render to keep water out. There's no cavity to break the moisture path. Failed pointing, cracked render, or deteriorated cills and flashings lets rainwater penetrate, often appearing as damp patches that worsen in wet weather. Our diagnosis separates penetrating damp from rising damp before any treatment starts, because the repair work is completely different: repointing, render repairs, or flashing replacement rather than chemical injection.
Damp proofing process and timescales for Greenwich properties
Most damp proofing work in Greenwich properties takes one to two weeks from start to finish, including diagnosis, treatment, and replastering where needed. Here's how we typically run a job.
Free damp survey and written report for SE10 and SE3 properties
We visit the property, use moisture meters and thermal imaging to locate damp and identify the type, and provide a written report with findings and a fixed-price quote. There's no charge for this. For listed properties in the Greenwich conservation area, the report also notes any material constraints, lime plaster requirements and conservation-compliant finishes, that affect the treatment spec.

Frequently Asked Questions
- What does damp proofing in Greenwich involve?
- We confirm the scope after a free site visit because it depends on the type of damp, the number of walls affected, and whether replastering is needed. Rising damp treatment on a single wall in a SE3 Victorian semi is a very different job to tanking a basement in a Georgian townhouse near the Thames. We provide a fixed written quote before any work starts, so there are no surprises on the final invoice.
- What types of damp are most common in Greenwich's period properties?
- Rising damp is the most common issue we find in SE10 and SE3 Victorian and Georgian terraces. Original slate DPCs deteriorate over time, and raised external ground levels can bridge an intact one. Penetrating damp through solid brick walls is also frequent, usually caused by failed pointing, cracked render, or deteriorated window cills. Condensation is the most common cause of black mould in kitchens and bathrooms but is separate from structural damp and needs different management. We diagnose all three types using moisture meters and thermal imaging before recommending treatment.
- Do your damp proofing treatments come with a guarantee?
- Yes. Chemical DPC injection carries a 20-year written guarantee backed by the product manufacturer (we use Safeguard or Sovereign silicone cream systems). Basement tanking carries a 10-year guarantee. All guarantees cover materials and workmanship, and we provide a Property Care Association compliant certificate with the paperwork. Solicitors and mortgage lenders regularly request this during conveyancing.
- Why use All Well for damp proofing in Greenwich rather than a national franchise?
- We know the specific stock in SE10 and SE3, solid brick Georgian and Victorian construction with no cavity, lime-based original plaster, conservation and listed building constraints. National franchise surveys can misdiagnose condensation as rising damp or recommend treatments that aren't compliant with the Royal Borough of Greenwich's conservation requirements. We diagnose first, fix second, and use lime-compatible replastering systems where the property requires them.
