Open-vented to sealed in three days
A 1978 system with a loft tank and a radiator that gurgled. Now a sealed system with an unvented cylinder. The loft is a loft again.
The leak that was never under the bath
A stain on the kitchen ceiling, a bathroom that was dry. We traced it to a corroded joint behind a stud wall, cut one small hole and closed it again.
Kitchen and bathroom, first fix to final
Both rooms re-piped in 15 mm copper, isolators on every appliance, pressure-tested and signed off before the plasterer came in.
No hot water on a Sunday, fixed by Sunday
A failed diverter valve. We carry the common ones on the van, so the family had hot water by teatime.
