Alpha Advantage

About three weeks ago I sought bids for a sprinkler system for a small sodded yard, covering roughly 6000 square foot. Bob, the owner, came out within a day and gave me a consult followed by a bid that turned out to be SUBSTANTIALLY lower than four others by far. I was concerned that if I went with Alpha Advantage I may be disappointed. However--just the opposite-- I was extremely impressed!! His crew arrived just before 9 am and by the end of first day the crew had carefully removed my sod by carefully cutting out strips followed by digging trenches and installing the pipes. The next day the crew again arrived bright and early to finish the work of installing the sprinkler heads, control unit and replacing the sod, compacting the soil as they did so that one cannot tell that lines
