Not only efficient and competent but also courteous, punctual, dependable; our H.D. Johnson plumbers have installed for us a boiler and radiators; radiant heat under a bathroom floor; toilets and a bidet; sinks and faucets; elaborate shower fixtures; and air conditioning.

The level of service could not be better.
