Our take: The 4.9 rating comes from a review base well under Mullen's, but the jobs reviewers describe, from gas leaks to emergency drain problems, are exactly what people call a plumber for. Strong pick for gas work and quick scheduling.

Al Marino Inc., Plumbing, Heating, Cooling & Electrical

4.1239 Google reviews

Al Marino Inc., Plumbing, Heating, Cooling & Electrical is a Charleston company on 4th Avenue that lists plumbing, drain and sewer, heating, cooling and electrical work, and bills itself as a 24/7 contractor. Google types it as a plumber, with HVAC and electrician categories as well. The reviews here mostly describe HVAC and electrical jobs rather than plumbing, so the plumbing evidence here is thinner than for the other names.

What people praise

Technicians who explain options and terminology clearly
Plumbing, heating, cooling and electrical under one roof
Prompt help on an HVAC install problem the company did not perform

Worth knowing

Some reviewers say after-hours help did not match the 24/7 billing, so confirm evening coverage when you call
Few reviews describe plumbing work

How the scores work

Every figure on this page comes from public Google data on the date shown. Rating is the live Google average. Review volume is how many customers have rated the business, compared across the plumbers listed. Confidence weighs the rating by that volume, so a 4.7 from more than a thousand people counts for more than a 5.0 from a few dozen. Recency shows how recently reviews are still arriving.

What do Charleston plumbers charge?

No price list is published by these businesses, so there is no cost table here. Price moves with the job, access to the pipe, the time of day and whether a permit or new parts are needed. The one concrete figure in the reviews is a Mullen customer who paid $567 for a toilet repair and a shower-drain unclog.

Do any of these plumbers also do heating, cooling or electrical work?

Mullen and Al Marino both list heating and cooling, and Al Marino’s site adds electrical work. A&P and Truslow are plumbing-focused, though an A&P owner reply says HVAC may be added later and Truslow also lists remodeling.
