Editorial Review
Our Take on Excel Plumbing and heating
A small Dorchester-based operation with a spotless Google rating, though on a review count low enough that it reads as promising rather than proven. The weekday-only published hours are the thing to weigh: this is a company for planned repairs and heating season work, not for burst pipes at midnight. Confirm licence and permit arrangements on any boiler or water heater replacement, as you would with anyone.

About Excel Plumbing and heating
The address at 256 Ashmont Street puts this business in the middle of one of Boston's older residential districts, where triple-deckers, converted two-families and small commercial storefronts sit on pipework that has been patched by several generations of tradesmen. Work in that housing stock tends to follow a pattern: cast iron waste lines that have thinned at the bottom, galvanised supply that has narrowed to a trickle, and heating systems that were converted from one fuel to another somewhere along the line. Excel Plumbing and Heating positions itself around exactly that mix, with water heater installation, leak detection and repair, and boiler service given top billing on its own website, alongside general plumbing and drain cleaning.
The service area listed is wide for a small company. Boston neighbourhoods including Dorchester, South Boston, Roxbury, Charlestown, the Back Bay and the South End are named, and so are Cambridge, Somerville, Chelsea, Everett, Malden, Medford, Arlington, Belmont, Brookline, Chestnut Hill, Lexington, Winchester, Waban and Wellesley. That spread crosses a lot of different building types, from Back Bay brownstones with tight cellars and shared risers to postwar single-family houses out along Route 2. It also crosses a lot of permitting jurisdictions, which matters more than people expect. Massachusetts runs a state plumbing and gas code and requires licensed journeymen and masters, and most municipalities want a permit pulled and an inspection signed off for water heater swaps, boiler replacements and gas line alterations. Ask who is pulling the permit and whose licence number goes on it before any replacement work starts.
Heating is the half of the trade that defines the calendar around here. A Boston winter puts steady load on boilers from roughly October through April, and the housing stock still holds a great many one-pipe steam systems along with older cast iron hot water boilers and, increasingly, wall-hung condensing units. Steam is a genuine specialism, with its own logic around venting, pitch and near-boiler piping, and it is worth asking directly whether a company works on steam or mainly on forced hot water before booking a diagnostic. Boiler services are advertised here as maintenance and repair work as well as installation, which suggests annual cleanings and combustion checks are part of the offering.
Water heaters are the other steady earner. In a triple-decker, replacing a tank often means getting a new unit down a narrow bulkhead or up a back staircase, dealing with an existing chimney vent that may not meet current code once a higher efficiency appliance is installed, and sorting out expansion tanks and thermal expansion control that older installations rarely had. When getting a quote, ask whether the price includes the permit, the disposal of the old tank, a new shutoff and a drip pan, and whether the venting will be reused or replaced. Those items are where estimates diverge.
On hours, there is a small discrepancy worth knowing. The Google profile lists 7:30 in the morning to 4:30 in the afternoon Monday through Friday, while the website's footer says 8:00 to 4:30 across the same days. Both agree on weekends closed. The About page mentions emergency plumbing among the work handled, but no after-hours or 24-hour availability is published anywhere in the material, so anyone who needs a middle-of-the-night response should confirm that by phone rather than assume it. Excel Plumbing and Heating looks best suited to scheduled work: a failing water heater you have caught early, a boiler that needs a proper service before the cold sets in, a leak you have found behind a wall, a drain that keeps backing up.
As for how it compares in this market, Boston has plenty of larger plumbing and heating firms with radio advertising, flat-rate price books and vans out around the clock, and it has plenty of one-truck operators who are excellent and impossible to reach. This one sits nearer the small end, with online booking and a chat option that suggest an interest in making contact easy. The Google Business Profile rating of 5 from 17 reviews, read on September 4, 2026, is consistent and clean, though 17 is a small enough sample that it should be read as a good sign rather than a long track record. A free estimate is advertised, and it is reasonable to get two or three quotes on any replacement job before committing.

Excel Plumbing and heating FAQs
Where is Excel Plumbing and Heating based and what areas does it cover?
The business operates from 256 Ashmont Street, Suite 3, in Dorchester, Boston, MA 02124. Its website lists a service area covering Boston neighbourhoods including Dorchester, South Boston, Roxbury, Charlestown, the Back Bay and the South End, plus surrounding communities such as Cambridge, Somerville, Chelsea, Everett, Malden, Medford, Arlington, Belmont, Brookline, Chestnut Hill, Lexington, Winchester, Waban and Wellesley.
Does it handle emergency call-outs at night or on weekends?
Published hours are Monday to Friday only, with Saturday and Sunday closed, so weekend and overnight availability is not confirmed. The company's About page does mention emergency plumbing among the work it takes, but no 24-hour service is advertised anywhere in its material. If you need urgent after-hours help, call (617) 913-3524 and ask directly rather than relying on the listed hours.
What are the opening hours?
The Google Business Profile lists 7:30 AM to 4:30 PM Monday through Friday, closed at weekends. The company's own website footer gives 8:00 AM to 4:30 PM for the same weekdays, also closed Saturday and Sunday. The half-hour difference is minor but worth confirming if you are hoping for an early morning slot.
How is it rated?
It holds a 5 out of 5 rating from 17 reviews on its Google Business Profile, read on September 4, 2026. That is an unblemished score, though on a fairly small number of reviews, which is common for smaller crews. Treat it as a good early signal and still ask for references on larger replacement jobs.
Does it work on steam boilers?
The website advertises boiler installation, repair and maintenance but does not specify steam versus hot water systems. Plenty of older Boston housing still runs one-pipe steam, which is a distinct skill set from forced hot water, so ask when you call whether they service steam and what experience they have with near-boiler piping and venting on those systems.
Will a permit be needed for a water heater or boiler replacement?
In most Massachusetts municipalities, yes. Water heater swaps, boiler replacements and gas line alterations generally require a permit pulled by a licensed plumber or gas fitter and an inspection afterwards. Excel Plumbing and Heating states that its technicians are licensed. Confirm the licence number, who is pulling the permit and whether the permit fee is inside the quoted price before work begins.
Can you book online?
Yes. The site offers a Book Now option and a chat feature alongside the phone number, (617) 913-3524, and an email address. A free estimate is advertised through the contact form. For anything urgent, the phone remains the faster route during weekday business hours.
Is Excel Plumbing and heating licensed and insured?
We have no credential records on file for this company yet. Ask for the certificate directly from the insurer before booking work.
What areas does Excel Plumbing and heating serve?
Boston, Somerville, Chelsea, Dorchester, Hyde Park, Brookline, Quincy. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.
Does Excel Plumbing and heating offer emergency service?
Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.
What warranty do they offer?
Warranty terms are not on file. Ask for them in writing before work starts.
How was this profile built?
Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.
Can a business pay to improve its profile?
A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
