Robertson Plumbing and Heating renovates and builds plumbing, heating and cooling systems for apartment buildings and complexes.

The company is currently installing a new water system in a 15-story apartment building in Silver Spring... while the building is occupied!

This means a parallel plumbing system must be put in place in order to redo the piping. The job requires a full team of plumbers and helpers on the job everyday, and will take about 6 months to complete.

The company's first large-scale commercial job was the 1988 renovation of the Boston Heights apartment complex in Annapolis.
