Flood & Damp Complaints

Flood & Damp Complaints2021-12-03T09:02:59+00:00

The cavity in external walls of homes was introduced in circa 1890 originally to avoid problems of dampness experienced by older solid walled dwellings.

Cavity wall construction generally consists of two leaves of masonry, an outer leaf (of facing brickwork, natural stone, blockwork with render, etc) and an inner leaf of brickwork or blockwork separated by a nominal 50mm wide cavity. Recent practice has been to fill the cavity with insulation materials to reduce heating bills and carbon omissions.

In common with the rest of the homes in the UK your cavity walls were probably built with all of the vagaries of normal “as-built on site” construction subject to variations in weather conditions, site practice, etc and the outer leaf of your walls allow rain water penetration, subject to the exposure conditions.

Published guidance by the Building Research Establishment (BRE) says that there is an increased risk of rain penetration if a cavity is fully filled with insulation. Rainwater may penetrate the outer leaf of a cavity wall, bridge the cavity via the insulation material and transfer moisture to internal walls, causing damp and consequent mould.

When standard (fibre, bead) insulation materials become wet they lose their thermal performance benefit, and your damp walls will conduct heat more readily than a dry wall increasing your heating bills.

Experience also shows that it pays to prepare in advance for the eventuality of flooding. If your home or business is flooded it can be extremely disruptive not just to the lives of your family but also to your business. The costs associated with extraction and removal of inappropriate insulation materials and prolonged drying out can be exorbitant, highly disruptive and cause unsightly damage to the external appearance of the property, and are not just measured in terms of money, time and aesthetics but also inconvenience and heartache to you, your family and, if a business, your employees and their families.

I-CAN offer independent impartial inspection surveys to check whether your home is at risk, and advice on remedial works, if required, for your home or business.
