Damp Proofing Specialists in Kensington (W8, W14)
Professional damp proofing specialists in Kensington, West London.
Why Choose All Well for Damp Proofing in Kensington?
Kensington's housing stock — Victorian terraces, stucco-fronted townhouses, and period mansion flats across W8, W14, and SW5 — was built before effective damp-proof courses were standard. Original slate or bitumen DPCs in these properties have often deteriorated over 100-plus years, and raised external ground levels frequently bridge whatever protection remains. Stucco render, if cracked or poorly maintained, lets penetrating damp track in through solid walls before the damage becomes visible inside. We work across the Royal Borough's conservation areas with the discretion and material knowledge these buildings require.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Damp Proofing Tip for Kensington Homeowners
If your Kensington property is listed or sits in a conservation area, any replastering after damp treatment must use lime-based plaster, not modern gypsum — RBKC enforcement on this point is real, and getting it wrong means stripping back and starting again.
Damp Proofing Victorian and Stucco Properties in Kensington
The solid-wall construction typical of W8 and W14 behaves differently from modern cavity-wall builds. There is no air gap to interrupt moisture travel, so a failed DPC or cracked render can saturate an entire wall section. We diagnose the cause first — using calibrated moisture meters and thermal imaging — before recommending treatment, because rising damp and penetrating damp through stucco look similar but need different fixes.
Rising Damp Treatment in W8 and W14 Terraces
In Kensington's Victorian terraces, rising damp typically presents as a tide mark up to one metre high, salt deposits on the plaster, and blown skirting boards at ground floor level. We treat it with silicone-cream DPC injection into the mortar course, then hack off the contaminated plaster and re-render using a renovation plaster system that resists residual salts. The injection treatment carries a 20-year guarantee. Where external ground level has been raised and is bridging the DPC line, we advise on reducing it — often straightforward in front-of-terrace situations but worth checking with RBKC before disturbing any front-area paving in a conservation zone.
Penetrating Damp Through Kensington Stucco Facades
Stucco is durable when intact but becomes a moisture reservoir once hairline cracks form — common on south-west facing elevations exposed to driving rain. We trace the entry point by checking render adhesion, inspecting window surrounds and cornicing junctions, and testing with a moisture meter at depth. Repair usually involves cutting out failed sections, repointing with a matched lime-based mortar, and applying a breathable protective coating. On listed townhouses in RBKC's conservation areas we use materials and finishes approved by the council's conservation officer.
Damp Proofing Solid-Wall and Basement Properties in Kensington
What we treat depends on what we find: the type of damp, the number of walls affected, whether replastering is included, and whether tanking is needed for a basement. We confirm the scope after a free site visit — no two Kensington properties present identically, and a written scope prevents disputes later.
Specialist Factors on Kensington Period Properties
Several factors shape the work in Kensington's older stock. Lime plaster replastering after treatment takes longer to dry than gypsum, but on a listed W8 townhouse it is not optional. Access to external walls in terraced situations often requires scaffold or tower rather than a ladder. Basement tanking on Kensington properties carries additional consideration because of the concentration of basement conversions in some streets and the effect on local groundwater; we factor groundwater conditions into our tanking specification. All of this is set out clearly in our written scope.
Damp Survey and Diagnosis Process for Kensington Properties
We do not recommend treatment before we know what we are treating. Our survey uses protimeter-type moisture meters, thermal imaging, and visual inspection of external fabric — pointing, render, flashings, gutters, and drainage channels. We provide a written report identifying the damp type and its source, with a fixed price confirmed after a free site visit. Work typically completes within one to two weeks of starting, depending on scope.
Working in RBKC Conservation Areas and Listed Buildings
The Royal Borough of Kensington and Chelsea covers almost the entire borough with conservation area designations, and a significant number of properties are listed. For a standard DPC injection this rarely affects the treatment itself, but replastering, external render repairs, and any work affecting original fabric on a listed building may require a Listed Building Consent check before starting. We flag this in our survey report and advise on whether a consent application is needed — we have worked with conservation architects familiar with RBKC requirements and can refer you if it comes to it.

Frequently Asked Questions
- How much does damp proofing cost in Kensington?
- We confirm a fixed price after a free site visit, because the work varies significantly by damp type, wall area affected, and whether replastering is needed. Rising damp treatment combines DPC injection and renovation plaster; basement tanking is a separate specification. On Kensington period properties we replaster with lime rather than gypsum, because it is the correct material for solid walls and a requirement on listed buildings under RBKC policy. We provide a written scope before any work starts.
- Does the stucco on my Kensington townhouse make damp treatment more complicated?
- Not more complicated, but it does change the diagnosis. Stucco that has cracked or lost adhesion is a common entry point for penetrating damp in W8 and W14 properties. We check the render condition as part of the survey — including around window surrounds, bay junctions, and cornice lines where water tends to track in. Repair uses lime-based mortar and breathable coatings matched to the original profile. On conservation area properties we are careful about render colour and texture to avoid triggering a planning query with RBKC.
- Do you guarantee damp proofing work in Kensington?
- Yes. Chemical DPC injection using silicone-cream systems carries a 20-year written guarantee covering both materials and workmanship. Basement tanking systems are guaranteed for 10 years. We provide full documentation, including a Property Care Association compliant certificate, which solicitors and mortgage lenders routinely request during conveyancing on Kensington properties where proper documentation is essential.
- Why choose All Well for damp proofing in Kensington?
- We do our own surveys rather than sending a salesperson, and we diagnose before recommending. On a Kensington period property — solid walls, lime plaster, stucco render, possible listed status — the wrong diagnosis leads to treatment that does not work and materials that cause more damage. We work across W8, W14, and SW5, we know how RBKC conservation policy affects material choices, and we do not start work until we have given you a written scope and a fixed price.
