Masonry treatment cream-

Prevents penetrating damp and reduces heat loss

Properties with solid walls in London lose around 45% of their heat through walls. These properties are often referred to as ‘hard to treat’ when it comes to trying to insulate them as the options are restricted to expensive external cladding which alters the appearance of a building or fitting insulated plasterboard internally which reduce room dimensions.

London Damp & Mould Control's external waterproofing treatment with STORMDRY prevents heat loss and is much cheaper and less disruptive than having solid wall insulation installed.

The treatment is best explained by the following analogy: If you get caught in a heavy rain shower without an umbrella you are going to get soaked through and you begin to feel very cold and you’ll want to take off the wet clothes as soon as you get home.

The reason behind this is that wet materials, clothes, brickwork –anything that gets wet conduct or transfer more heat readily than dry materials. In the case of building materials a completely saturated brick will transfer approximately twice as much heat as an identical dry brick.

By keeping a building’s wall drier it is possible to significantly reduce the heat that is lost through them and STORMDRY water-proofing cream will help provide a warmer, drier home.

Applied externally as a single coat of cream it will last for 20 years and STORMDRY is a specially formulated waterproofing cream that penetrates deeply into walls and reduces the amount of moisture they can absorb. A dry wall conducts much less heat that a wet or damp wall and therefore more heat is retained within a property as less heat is being transferred through the walls.

This unique waterproofing cream is formulated to line the pores of masonry rather than block them, so vapours can still pass through the fabric of the building allowing it to breathe.

When applied the cream is white but within 48 hours it will have penetrated deep into the wall leaving no discolouration , residue or sheen.

Independent tests have showed that in damp weather a house treated with STORMDRY used between five and ten percent less energy. Standard Assessment Procedure (SAP) tests for heat loss showed that when driving rain was present the energy saving in a treated house increased to 29%.

A house treated with STORMDRY waterproofing cream will have lower carbon dioxide emissions and the heat saved will result in a higher grade Energy Performance Certificate


Some of the benefits of having a STORMDRY water repellent masonry protecting treatment are:-


All STORMDRY water-proofing and insulation treatments are backed by a twenty year insured guarantee which is issued by Guarantee Protection Insurance and is authorised and regulation by the Financial Conduct Authority.

STORMDRY is manufactured by Safeguard Chemicals who are members of the BWPDA and Property Care Association (PCA)

To minimise heat loss and keep internal wall surfaces warm we recommend the application of Wallrock Thermal Liners. These thermally efficient wallpapers will stop heat from being absorbed by cold walls and therefore reduce your heating bills and also prevent condensation and toxic black mould.

Wallrock Thermal Liners have been tested and approved by the British Board of Agrément (BBA) whose tests prove that using Wallrock Thermal Liners reduces heat loss by 20% with a substantial reduction in heating bills.
