Why Damp is a Problem in London?

London’s unique combination of housing stock and environmental conditions mean that damp is a frequent challenge for homeowners and landlords throughout the city.

Many of London’s properties were built before damp-proofing techniques were standard across newly built properties, and long before the standards of modern damp proofing techniques.  

In fact, older terrace houses in London from the 1800s and 1900s are especially vulnerable to rising damp, where moisture from the ground is drawn up through walls in a process known as capillary action, causing tide-marks, blistering plaster and peeling paint. 

Combine this rising damp with a lack of ventilation in plenty of older housing stock, and the kind of defects you find in ageing properties, and you can see why London housing is so prone to the likes of condensation and penetrating damp issues. 

Luckily, our team in London are all locally-based, so they understand the challenges unique to the city and can help you with any damp proofing requirements you may have. 

Our Damp Proofing Services in London

Our specialist damp proofing solutions in London are capable of addressing any and all damp problems you might encounter in any London home or commercial property:

Rising Damp Treatment in London

Peeling wallpaper, ruined skirting boards, and tide marks rising up to one meter above ground level are all signs of rising damp. Our surveyors will investigate your property for signs of rising damp, for evidence of a working or failed damp proof course, or discover if new damp proofing materials need to be installed. 

Once finished, our surveyors will deliver a written report detailing all of their findings, including their reccomendations on any damp proofing work we reccomend which can be undertaken by our team of London based, PCA-qualified technicians. 

Penetrating Damp Treatment in London

Penetrating damp is caused by moisture entering a property through defects like failed pointing, leaking gutters, blocked drains, and many other property care issues. These are problems that can easily get worse with age, and with some of London’s housing stock being older, penetrating damp is a common problem. 

Our team can assess your property in London for signs of penetrating damp, before delivering our tailored report, which will include our recommendations on damp proofing solutions that can be enacted by our local team of PCA-qualified technicians. 

Condensation Control and Mould Prevention in London

Condensation is one of the most common causes of damp in London, and cases are on the rise. Ground floor and high-rise flats, terraced properties, and even detached and semi-detached properties are all at risk, thanks to high levels of humidity and a low level of ventilation options.

Not only will our surveyors be able to identify the causes of condensation in your property, but they will also be able to suggest everyday improvements to improve ventilation and airflow to lower the rate of condensation and black mould growth. 

Timberwise also offer different services and products in the way of condensation control, including positive pressure units, and specially designed ventilation fans to reduce the build up of condensation.
