The Importance of Damp Inspections for London Homeowners

The Importance of Damp Inspections for London Homeowners

3rd July, 2025

London and the southeast have a wet and dull climate, which is conducive to moisture penetration that can seriously damage buildings. We all lead busy lives, some of us are hardly at home, working round the clock to find the means to enjoy life, while also paying all the bills, and if you are not vigilant, you can miss the tell-tale signs of damp. Weeks become months that turn into years and if your property has damp issues and you have missed the early signs, this could lead to repairs in the thousands of pounds!

Homebuyer survey

At London Damp Surveys, we offer London property owners a comprehensive survey regarding damp and mould, which is the definitive way to find out if your home is, in fact, free from moisture penetration. The survey is ideal for those who are planning to put their home on the market, those who are looking to buy and homeowners who are proactive with building maintenance. We inspect the exterior and interior walls, test the air for humidity and examine roof timbers, looking for tell-tale signs of penetrating damp and mould. We use state of the art equipment to help determine the presence of moisture, including thermal imaging, hygrometers and moisture meters, while we use drones to carry out roof inspections.

Tell-tale signs to look for in your home

When carrying out a damp inspection, look out for the following:

  • Moss and mould growth on exterior walls
  • Crumbling mortar
  • Damp patches on interior walls and ceilings
  • Musky smell in the house
  • Green or black growth on timber
  • Condensation on windows and walls
  • Discolouration on walls
  • Peeling wallpaper
  • Bubbling paint on timber surfaces

A comprehensive damp inspection includes a visit to the loft with a torch to closely inspect joists and rafters and the integrity of the inner sheets that are laid under the roof tiles. If you have a water tank in your loft, examine this for signs of leaks.

The best time for a damp inspection

The ideal time to carry out a damp inspection of your home is the autumn months of September and October, although an inspection can be undertaken at any time. Pre-purchase inspections make a lot of sense if you are planning to make an offer on a London property. Some London homeowners arrange a damp survey on an annual basis to make absolutely sure the building is free from damp, mould and woodworm. This ensures there are no nasty surprises regarding damp issues in your home and for what it costs, it is well worth having done every year.

London Damp Surveys has been inspecting London homes for many years and we have a fantastic name in the industry, reflected by the many glowing testimonials that customers leave on a leading independent review platform.
