Damp-Proof Render in Portsmouth
Specialist waterproof and salt-resistant render systems for damp-affected and below-ground walls.
Our damp-proof render work in Portsmouth starts with a free survey, because guessing at a render specification is how jobs go wrong.
Across Hampshire, Georgian and Victorian housing, flint and brick cottages and extensive modern development dominates, and coastal salt on Portsmouth and Gosport properties, EWI on solid-wall stock is what we are called out to most often.
With mild southern conditions with coastal exposure, specification matters more in this part of the country than a national price list suggests. Flint-and-brick construction across the chalk downland needs lime, while the coastal cities are dominated by solid-wall terraces suited to external insulation.
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 Portsmouth
How long before I can decorate?
Allow a minimum of several weeks for the wall to dry, longer after flooding. Decorating too early traps moisture and the finish fails.
Can salt damage come back?
Not if the source of moisture is fixed and a salt-inhibiting system was used. Recurrence almost always means the underlying cause was never resolved.
How long does a rendering job take?
A typical three-bedroom semi is usually one to two weeks on site including scaffold, preparation, application and finishing. Weather, wall condition and the system chosen all move that.
Do I need planning permission to render my house?
Usually not on a standard house, but you will if the property is listed, in a conservation area, or if rendering would significantly change its appearance. We flag it at survey.
Will you need scaffolding?
For anything above single storey, yes — it is safer and produces a better finish than working off ladders or towers. Scaffold is included and itemised in the quote.
