How the top plumbing pros compare
The same ServiceAgent Score components that drive the ranking, scored side by side — so you can see at a glance where each provider is strongest.
The criteria we scored against
- 1. Trust (data & verification). Owner-verification, completeness of contact info, and review-volume credibility.
- 2. Recommendation (rating). The Google star rating, Bayesian-shrunk toward the category mean so a few 5-star reviews can't dominate.
- 3. Review depth. How many public reviews back the rating — more reviews, more reliable the signal.
- 4. Score confidence. How much data stands behind the composite score for this provider.
| Provider | Trust (data & verification) | Recommendation (rating) | Review depth | Score confidence |
|---|---|---|---|---|
| Roto-Rooter Plumbing & Water Cleanup | Strong | Strong | Strong | Strong |
| Horvitz Plumbing & Heating | Strong | Strong | Moderate | Strong |
| Croft Plumbing Services | Moderate | Strong | Limited | Limited |
| I&C MECHANICAL , INC. - Plumbing, Heating and Air Conditioning | Moderate | Strong | Limited | Limited |
| Excel Plumbing and heating | Moderate | Strong | Limited | Limited |
| Primetime Boston Plumbers | Moderate | Strong | Limited | Limited |
How we chose these
Same scoring engine as the main Boston plumbing ranking, with an additional filter step: we look for Commercial signals in each provider's business categories, service tags, and recent review text.
When the Commercial filter would surface fewer than five providers, we fall back to showing top-rated plumbing pros generally - they are far more likely to handle commercial work than an unrated provider would be.

How to choose a plumbing pro
The ranking does the research; these five checks help you turn the shortlist into the right hire.
- 1
Start with the top of the ranking, not an ad
The providers ranked highest in Boston earned it on review depth, rating, and data completeness — not on ad spend. Shortlist two or three from the top before you start calling.
- 2
Get two or three quotes in writing
Pricing for plumbing work varies by scope and local market. Written quotes from a few shortlisted pros let you compare apples to apples and spot an outlier before you commit.
- 3
Read the most recent reviews, not just the average
A strong average can hide a recent slide in quality. Sort reviews by newest and look for how the business handles problems — a thoughtful reply to a bad review often tells you more than the star count.
- 4
Confirm licensing, insurance, and scope before work starts
Ask for the license number and proof of insurance, and get the full scope of work plus any parts/labor warranty in writing before any plumbing job begins. Verify the license on your state board if the work is significant.
- 5
Match the provider to your actual job
A high-volume operator is great for a routine job; a smaller specialist may be a better fit for an unusual one. Use the scorecard above to pick for your situation, not just the overall rank.

What to know about hiring Plumbing
Plumbing jobs split into emergencies (leaks, clogs, no hot water) and planned work (re-pipes, fixture installs, water heaters).
What drives the price
Whether it's diagnostic vs. repair vs. replacement, access to the pipes, and emergency timing.
What to check
State plumbing license, insurance, and whether they give a flat quote after seeing the job rather than an hourly open-ended rate.
When to call
For a slow leak, sooner is cheaper — water damage escalates fast. Keep an emergency number on hand before you need it.
