Barnet, Greater London
Damp-Proof Render in Barnet
Specialist waterproof and salt-resistant render systems for damp-affected and below-ground walls.
We carry out damp-proof render across Barnet and the surrounding Greater London area throughout the year.
Across Greater London, Victorian and Edwardian terraces, interwar suburban semis and high-density modern development dominates, and solid-wall Victorian terraces, party-wall constraints and heavy atmospheric soiling is what we are called out to most often.
The area sees a drier urban climate with a pronounced heat-island effect, which is the single biggest factor in how long any render lasts here. Atmospheric pollution soils render faster in london than anywhere else in the uk, which is why self-cleaning silicone finishes are specified so heavily here.
When damp-proof render is the right call. Choose a damp-proof system after flooding, alongside DPC works, on below-ground walls, and wherever salt contamination is destroying normal plaster.

FAQs
Damp-Proof Render in Barnet
Does damp-proof render cure rising damp?
No — it manages the consequences. The damp-proof course or the source of water has to be dealt with separately. The render then holds back residual moisture and salts while the wall dries.
Is waterproof render the same as tanking?
Related but not the same. Tanking is a higher-specification below-ground system designed to resist water under pressure; waterproof render is for above-ground damp resistance.
How much does rendering cost?
It is priced by the square metre and depends on the system, the condition of the walls and access. Our guide-price tool gives an indicative range in about a minute, and the survey turns that into a fixed written quote.
Do you offer a guarantee?
Yes. Every job carries our workmanship guarantee, and where a full manufacturer-specified system is installed you also get the system warranty on top.
What time of year is best for rendering?
Spring through autumn is ideal. Render should not be applied in frost or in very hot direct sun, so winter work needs protection and settled conditions.
