O P Viau & Sons Inc

Founded in 1920, O P Viau & Sons Inc has kept Greater Lowell, MA flowing for over a century. The company holds MA Master Plumber License 10577 and NH Master Plumber License 3018, serving residential, commercial, and industrial customers across Lowell and surrounding communities. With a 1.5-star average across just two published reviews, the contractor operates 24 hours a day, every day of the week, under the banner of a name that has been a fixture in the region since the Hoover administration.

One practical advantage O P Viau & Sons maintains is dual-state licensing, credentialed to operate legally in both Massachusetts and New Hampshire under numbered master plumber permits. This is uncommon among single-state operators and matters to homeowners with investment properties in both states. The company offers plumbing, heating, cooling, and drain services from a single dispatch line. All plumbing work references a licensed master plumber by credential rather than an apprenticeship, a distinction that speaks to accountability at the highest trade classification.

Both published reviews express serious concerns about pricing and ownership changes following what appears to be a company acquisition. Satheesh Donthy reports that travel charges shifted from $0 to $85, and hourly labor from $90 to $145 per hour, after the takeover. Donthy specifically warns that parts markups jumped to three to five times list price and advises shoppers to request a breakdown before agreeing to service. A second reviewer, Elliot Alderson, directly questions whether current operators are genuinely the legacy Viau company. Neither reviewer names a technician by name, and no positive service stories appear in the available review set.
