Leak Detection in Chesham and Amersham

Chesham has Victorian terraces and cottages close to the centre, 1930s semis on the hillsides and post-war estates further out. The villages of Chartridge, Ley Hill and Hyde Heath lie beyond. Amersham-on-the-Hill and Chesham Bois grew with the railway and are mostly interwar houses on generous plots, many extended more than once. Old Amersham has brick and timber framed houses that have been replumbed many times. Little Chalfont is largely post-war detached. The water here is very hard, so copper pipework in walls and floors tends to pinhole where scale has built up. Pipes chased into plaster are a frequent source of damp patches.

We cover HP5, HP6 and HP7, including Chesham, Chesham Bois, Chartridge, Ley Hill, Hyde Heath, Amersham-on-the-Hill, Old Amersham, Little Chalfont and Coleshill. Calls are usually a damp patch on a wall that keeps coming back, a boiler losing pressure, or a water bill that has jumped. Pipes buried in a wall chase are found with the thermal camera when warm and with tracer gas when not, so only the chase itself is opened. Heating circuits are pressure tested first. Supply pipes under gravel drives are listened to with the acoustic ground microphone and confirmed before any digging.

Parking is simple on almost every road here, and most houses have a driveway. Chesham town centre and Old Amersham have some controlled parking where we carry the kit in. We mark the leak point on the wall or floor, keep dust to a minimum and tidy up. The written report includes photographs, thermal images and readings and is laid out for a trace and access claim on your buildings insurance.
