Average cost of damp proofing in London

The average cost for damp proofing in London can range anywhere from £1,000 - £5,000, depending on the property size, type, and age, the type of damp you have, the size of the affected area, and any additional work required like replastering or repainting.

To break down the cost further, there are three main types of damp, each with different treatment approaches and costs: Condensation damp treatment cost: £150–£400 per room

Usually caused by poor ventilation or humidity. Treatment may include improving airflow, installing vents, or applying anti-condensation paint.

Penetrating damp treatment options costs: £350–£1,000 per wall

Caused by water ingress through walls, roofs, or gutters. To combat penetrating damp, a professional can fix leaks, apply waterproof coatings, or repair brickwork and pointing.

Rising damp solutions costs: £500–£2,000+ per wall

The most complex and costly to fix, rising damp occurs when moisture travels up through walls from the ground. Treatment often involves installing a damp proof course, replastering, and redecorating.

Different damp types require different solutions, so ask the damp specialist in London to explain their recommended approach and why it’s the best option for your home.

Is the work compliant with building regulations?

Clarify what the quote encompasses, with typical services including a site survey, a written report, labour, materials, and any replastering or repainting, so there are no surprises later.

How long will the job take to complete?

Ask for a realistic timeline based on the type of damp, the size of the affected area, and any additional work like plastering or painting. This helps you plan around the disruption.
