About Sully's Plumbing and Heating in Chelmsford, MA

Frozen outdoor faucets are a common issue in our Chelmsford winters. First, turn off the water supply to that faucet from inside your home. Never use an open flame to thaw it. We recommend calling us for a professional assessment. We can safely thaw the line to prevent burst pipes and often suggest installing frost-proof hose bibs, which are better suited for our climate, to prevent future freezing and water damage.

Many older homes in Chelmsford have cast iron drain lines that can corrode and clog over time. We offer comprehensive drain repair and plumbing inspection services specifically for these systems. Using camera inspections, we can locate the exact problem, whether it's a blockage or a break. We then provide clear options, which can range from cleaning and snaking the line to a partial or complete plumbing replacement with modern, durable materials to restore proper flow and prevent future issues.

With our roots in hydronic and steam heating since 1984, we provide expert HVAC installation, replacement, and repair. This includes servicing boilers, radiators, and baseboard heating systems common in many area homes. Whether you need a routine tune-up for your existing system, a repair to get your heat running again, or a full system replacement for better efficiency, our team has the specialized knowledge to ensure your Chelmsford home stays comfortably warm.
