Recent feedback from landlords and homeowners:

“Very thorough workmanship. While everyone had been guessing about the source of our plumbing problem, Kav persevered until he found the real source. Impressive!”

“Very reliable, fair and professional service. They refitted my bathroom and changed my boiler - clean work throughout. He returned three weeks later to check and monitor the system too. Highly recommended.”
