Sur­veyor warns of chem­i­cal rip-off

Yorkshire Post - Property - - PROPERTY -

CHAR­TERED sur­veyor Ian Rock, au­thor of the new Haynes Pe­riod Prop­erty Man­ual, says home own­ers are at risk of be­ing ripped off by con­trac­tors who sell chem­i­cal damp proof cour­ses for his­toric build­ings.

He says that most damp prob­lems in older prop­er­ties can be fixed by rou­tine main­te­nance that will grad­u­ally help the build­ing to dry out.

Chem­i­cal DPCs and ce­ment­based ren­ders risk trap­ping mois­ture in the walls.

He says: “Old houses need to breath, so by clear­ing away earth that is build­ing up against out­side walls, ap­ply­ing tra­di­tional lime-based mor­tars and mend­ing leak­ing drains you can solve many damp prob­lems over time.”
