Commercial Plumbers Repair

Plumbing problems in large commercial buildings are usually more complex and greater in scope than a residential plumbing problem. At Plumb Thermals we aim to overcome the emergency quickly and with as little disruption as possible to the work place. We use our knowledge and flexibility to adapt our methods to suit the building and the needs of the specific business

Commercial Leak Investigation

Leak investigation in a large building can be complex. A hidden leak may cause damage or de-pressurise a system causing heating systems to fail. Leaks can be traced through pressure tests or thermal imaging amongst other tools. A thorough analysis of the situation including the property and business will be taken into consideration when formulating a fix for the problem.
