The residents of the building complained of a leak in the stairwell. We carried out pressure testing, found a pinhole on the old riser and replaced the emergency section using argon-arc welding.

The old boiler had failed and a new wall-mounted unit needed connecting. We welded the joints on polypropylene and metal, and installed a filter and pressure gauge.

The owner was opening a catering outlet and needed a pipe run from the distribution cabinet. We laid an external gas pipeline, welded all the joints and carried out testing.

During earthworks an underground gas pipeline was struck. We responded promptly, welded up the crack and restored the insulation on the joint.
