Thirty-two years of plumbing in Ottawa

Alistair Calderwood completed his apprenticeship with a Bells Corners firm in 1991 and established Calderwood Plumbing and Heating in 1994, initially as a single-van operation serving Nepean and the western townships. The firm has grown to fourteen employees and six service vehicles, and has operated from the Capital Drive premises since 2006. The founder remains active in the field several days each week, principally on hydronic heating work. The firm has never advertised on radio or television and does not intend to; it has grown entirely on referral.
