           ​ In 1977 I began in the Plumbing Heating & Air Conditioning trades. After serving 2 decades as an apprentice & journeyman in the trades doing residential - commercial service & remodeling I began to do job costs and estimating while still working in the field at a technician - estimator level. In 2002 my employer of 6 years fell ill to cancer and was forced to retire. After a quarter of a century in the business it was time to move to the next level of my journey. This is where it all began with the intent of giving professional quality & service at a reasonable cost.
