Damp in Property: Identifying Issues and Seeking Independent Advice

Damp in Property: What Homeowners in South East London and Kent Must Know

Damp is one of the most commonly reported issues in UK homes — and one of the most misunderstood. From affecting health and destroying plasterwork to derailing property sales, untreated damp is a silent threat to homeowners in areas like Beckenham, Bromley, Catford, Eltham, Orpington, Greenwich, and Forest Hill.

The Main Types of Damp

- Rising Damp Caused by groundwater travelling up through porous bricks and mortar, often due to a failed or missing damp-proof course. It appears as tide marks, peeling paint, and bubbling plaster low on walls.

- Penetrating Damp This occurs when water seeps through walls or roofs due to defects like cracked render, blocked gutters, or broken pipes. It often results in discoloured patches and mould in isolated areas.

- Condensation By far the most common — and often misdiagnosed — condensation happens when moist air meets cold surfaces. It typically forms around windows, corners, or behind furniture, leading to black mould.

How to Spot Damp

- Musty odours

- Mould or mildew growth (especially black mould)

- Water staining or dark patches

- Wallpaper peeling or paint flaking

- Rotting skirting boards or floors

- Cold, clammy walls

In properties across Chislehurst, Dulwich, Lewisham, and Penge, older building materials and limited ventilation can make homes more vulnerable.

Caution: Beware of Biased Damp Surveys

Not all damp surveys are created equal. Many companies offer “free” damp surveys with the hidden motive of selling expensive treatments. These surveys are often carried out by salespeople rather than qualified, independent professionals.

At Integra Estates, we strongly recommend commissioning an independent damp survey — ideally by an RICS surveyor or a Property Care Association (PCA)-certified specialist — who doesn’t profit from the outcome. Independent surveys are objective and help you avoid unnecessary work or inflated quotes.

How to Treat and Prevent Damp

- Identify the cause – This is essential. Treating symptoms without addressing the source only leads to repeat problems.

- Ventilate properly – Use extractor fans, keep trickle vents open, and avoid drying clothes indoors where possible.

- Repair structural defects – Fix cracked masonry, leaky roofs, or faulty gutters.

- Consider damp-proofing – If rising damp is confirmed, chemical damp-proof courses or waterproof renders may be recommended.

- Use breathable materials – Especially in period homes found in Blackheath, West Norwood, and Upper Sydenham, avoid modern impermeable materials that can trap moisture.

Why It Matters Locally

Many properties across Addington, Avery Hill, Crofton Park, Shortlands, Sidcup, Tatsfield, and Woolwich date back to the Victorian and Edwardian eras, where cavity wall insulation was absent or poorly retrofitted. These homes require tailored solutions — not generic, over-the-counter fixes.
