I contracted with Ed Sealey to remove two (2) oil fired boilers and replace with one (1) gas fired boiler. I requested all of the piping to be done in copper. This was a bit of a complicated job because it required boring through two (2) concrete foundations to connect the new boiler to the existing system within an addition that originally contained it's own oil fired boiler. Sealey had to find the best run and work within constrained space to pull this off. The finished work looks like a piece of artwork. Ed provided a written quotation with numerous options within a timely fashion. Once we agreed on a price the project was completed within a matter of a week which included the removal of the existing boilers, tanks, etc. Very well organized and orchestrated. No wasted time with these guys. Very professional.
