Damp Proofing Specialists in Catford (SE6)
Professional damp proofing specialists in Catford, South East London.
Why Choose All Well for Damp Proofing in Catford?
Catford's Victorian terraces and Edwardian semis in SE6 were built before 1920, most with original slate or bitumen damp-proof courses that have since deteriorated or been bridged by raised external ground levels. Rising damp is one of the most consistent defects we diagnose at survey across these streets, the classic tide mark, salt deposits, and blown plaster at ground-floor level. Properties near the Ravensbourne corridor sit on lower-lying ground with higher persistent groundwater, which makes the problem more aggressive than on the higher streets away from the river. Many Catford terraces are bought unrenovated specifically for refurbishment, and damp treatment is a standard first step before any decoration work goes in.
Every project comes with a fixed-price contract, single project manager, and full certification including Building Control sign-off.

Damp Proofing Tip for Catford Homeowners
Lewisham Council does not require planning permission for internal damp proofing work, but if you are having DPC injection carried out as part of a wider renovation that includes external re-rendering, check whether the property sits within the Culverley Green conservation area, render colour and finish choices there need to be sympathetic to the street. We confirm the conservation area boundary at survey before specifying any external waterproofing or render systems.
Rising damp treatment on Catford SE6 period homes
The right damp treatment in Catford depends on the type of damp, the number of affected walls, and whether replastering is needed afterwards. We diagnose after a free site visit with calibrated moisture meters. There is no fixed formula because two terraces on the same street can present very differently depending on drainage, ground level, and how long the problem has been left. The price is fixed and confirmed after that survey.
Chemical DPC injection on Catford Victorian terraces
The majority of Catford's ground-floor rising damp cases are treated with silicone-based cream DPC injection. We drill at mortar-course level, inject, and allow 4 to 6 weeks for the wall to dry before replastering with salt-resistant render. All chemical DPC work carries a 20-year guarantee backed by the product manufacturer.
Basement and below-ground waterproofing in SE6
Some Catford terraces have semi-basement rooms used as storage or utility space. Where these show persistent water ingress, cavity drain membrane tanking is the more reliable solution than surface coatings on walls that see ongoing groundwater pressure. Tanking work carries a 10-year guarantee. Properties near the Ravensbourne corridor warrant particular scrutiny here given the lower ground levels.
Diagnosing damp in Catford period properties
We do not quote from photographs or descriptions. Every job starts with a site visit where we use a protimeter-type moisture meter and thermal imaging to distinguish rising damp from penetrating damp and condensation. They look similar but need different treatments. Getting the diagnosis wrong wastes effort and the problem comes back.
Rising vs penetrating damp in SE6 terraces
Rising damp in Catford terraces typically shows as a band up to 1 metre high on internal walls with salt efflorescence and crumbling plaster, most visible on the front elevation where external ground levels have been raised over decades. Penetrating damp usually appears at higher levels, tracking in through failed pointing, cracked render, or damaged flashings, and often worsens after sustained rain. Each needs a different fix.
Condensation and mould in Catford homes
Black mould in corners, behind furniture, and on north-facing walls is often condensation rather than structural damp, common in Catford's older houses with single-glazed windows and limited ventilation in kitchens and bathrooms. We identify condensation cases at survey and will not sell a DPC treatment for a condensation problem. Ventilation improvements or secondary glazing are usually the right answer.
Damp proofing as part of a Catford renovation
Most of the damp work we do in Catford sits within a wider renovation scope. Buyers purchase unrenovated Victorian terraces in SE6, often with decades of deferred maintenance, and commission us to treat damp as part of the full refurbishment, before rewiring, replastering, and decorating. Sequencing matters: damp must be treated and walls given time to dry before any new plaster or finishes go on, otherwise the new work fails quickly.
Sequencing damp treatment within a full refurb
On a Catford terrace renovation, we typically treat damp in week one or two of the programme, then run other trades, electrician, plumber, while the walls dry over 4 to 6 weeks. Replastering with salt-resistant render follows before skimming and decoration. This staging avoids the common mistake of decorating over a wall that has not fully dried out and then watching the plaster blow within a year.

Frequently Asked Questions
- How much does damp proofing cost in Catford?
- The right approach depends on the type of damp, the number of affected walls, and whether replastering is needed after treatment. We do not publish ranges because every property presents differently. We give a fixed price confirmed after a free site visit, where we diagnose the problem properly before specifying any work.
- How long does damp proofing take in SE6?
- Chemical DPC injection itself takes 1 to 2 days. The critical wait is the drying period: walls need 4 to 6 weeks after treatment before salt-resistant render and new plaster go on. If you are running a renovation alongside the damp work, we sequence other trades into that window so it does not add to the overall programme. A straightforward ground-floor damp treatment with replastering is typically complete within 1 to 2 weeks of the walls being ready.
- Do you guarantee damp proofing work in Catford?
- Yes. Chemical DPC injection treatments carry a 20-year written guarantee backed by the product manufacturer, suppliers such as Safeguard or Sovereign. Basement tanking systems are guaranteed for 10 years. We issue a Property Care Association compliant certificate with every job, which solicitors and mortgage lenders routinely request during conveyancing. If you are planning to sell a Catford property after renovation, having properly documented guaranteed damp treatment avoids hold-ups in the sale.
- Why use All Well for damp proofing in Catford rather than a specialist-only contractor?
- We are a full building firm, not a sales-led damp specialist. We diagnose first and only recommend treatment where there is a confirmed problem, we will not sell DPC injection for a condensation issue. Because we carry all trades in-house, we can treat the damp and immediately sequence the replastering, electrical, and decoration work that follows. For Catford renovation buyers tackling a Victorian terrace with multiple defects, having one contractor handle damp treatment and the wider refurbishment is more efficient and avoids the coordination problems that come with using separate specialists.
All Well has completed 100+ projects across 25 London boroughs since 2020. We are NICEIC approved for electrical work, FENSA registered for glazing, and CHAS certified for site safety, with Public Liability insurance to £5 million. 57+ Google reviews average 4.5 stars.
