About Ostroski Plumbing & Heating Inc.
Ostroski Plumbing & Heating Inc. operates as a licensed plumbing and heating contractor serving North Billerica, Massachusetts, and surrounding communities including Andover, Bedford, Chelmsford, Concord, and Tewksbury. With a rating of 4.9 stars from 232 customer reviews, the company has established a strong local reputation for residential plumbing solutions ranging from fixture installations and drain cleaning to complex system replacements. The business maintains standard weekday hours from 7 AM to 3:30 PM with Saturday availability for scheduled appointments.
What distinguishes Ostroski from typical local contractors is their commitment to community causes beyond service delivery. The company donates five dollars from every completed plumbing job to the SPC Matthew Pollini Memorial Fund, allowing customers to contribute to a meaningful cause through routine service calls. Their service portfolio encompasses both traditional plumbing infrastructure including water softeners, filtration systems, and backflow testing alongside modern heating solutions such as tankless water heaters, heat pump systems, and boiler installations.
Customer reviews consistently highlight responsive same-day service and transparent communication. When Bob DiCarlo called at 8:45 AM regarding a failed water heater, the team arrived by 10:30 AM the same morning. Multiple reviewers praise technician Brent for explaining repair details clearly while avoiding excessive charges that homeowners associate with competitors. Christine MacDonald's review describes the company handling diverse jobs including water line installation, dishwasher setup, boiler servicing, and leak repairs across her property.
What Customers Say
Seven reviewers specifically mention same-day or next-day service response, with several describing arrival within two hours of their morning call. Four customer accounts reference friendly coordination staff who answered phones directly and scheduled appointments promptly. Pricing transparency appears in four positive reviews contrasting Ostroski's reasonable rates against unexpected high costs from other companies.
