What We Like

• Repair-first approach, with the company stating it tries to fix existing plumbing before recommending replacement
• 4.8 from 64 reviews on its Google Business Profile, read on September 4, 2026
• Family-owned and trading in Dallas since 1986, per its own website
• Master plumber licence number M16292 published openly on the site
• Based in 75238, close to the older northeast Dallas neighbourhoods it serves
• Covers sewer line repair and camera inspections as well as everyday service calls

Things to Consider

• Published hours are Monday to Friday only, with no listed weekend or emergency service
• Presented as a residential plumber, so commercial and large remodel work may not be a fit
• Review count is modest compared with the larger advertising-led Dallas plumbing firms
• The site gives no pricing information, so rates need confirming when you book

Northeast Dallas houses, the ones around Lake Highlands, White Rock and the neighbourhoods off Audelia and Skillman, tend to be slab-on-grade builds from the 1950s through the 1970s with cast iron drain lines underneath and galvanised supply lines in the older examples. That housing stock generates a very particular workload: slow drains that turn out to be bellied pipe, water heaters in tight closets or attics, shower pans that fail quietly and rot out a subfloor, and sewer lines that need a camera down them before anyone starts guessing. Mai Plumbing Co Inc works from an address on Faircrest Drive inside that same 75238 zip, which puts the van close to most of the older neighbourhoods it serves.

The service list on the company's own site is a repair list rather than a remodel list. General residential service repair sits at the top, followed by water heater installation and repair, tankless installation, faucet and fixture work, drain cleaning, shower pan testing, sewer line repair and camera inspections. The company is explicit that while upgrades and new installations are sometimes the right answer, repair plumbing is the market it caters to and it prefers to fix what is already there. That is worth reading carefully. A homeowner who wants a bathroom gutted and rebuilt from the studs is probably talking to the wrong firm. Someone whose 14-year-old water heater is dripping and who wants a straight answer on repair versus replacement is talking to exactly the right one.

A family business trading since 1986 has seen several Dallas plumbing eras pass through. It has watched cast iron reach the end of its service life across whole streets, seen tankless units go from novelty to common, and worked through the code changes that came with them. The site says growth has come almost entirely by recommendation rather than advertising, which is consistent with a small operation that keeps a steady book rather than chasing volume. The published licence number, master plumber M16292, is the thing to note: in Texas, plumbing work is regulated by the state board, and a licence number displayed openly is easy for a homeowner to check before anyone comes out.

Hours are the main practical constraint. Monday to Friday, 8am to 5pm, with Saturday and Sunday closed. There is no published after-hours or emergency service, so a burst supply line on a Sunday afternoon means either shutting off the main and waiting or calling one of the larger Dallas outfits that staffs nights and weekends at a premium call-out rate. For scheduled work, that same weekday-only pattern often means fewer rushed jobs and a clearer diary. Ratings back that up to a point: the Google Business Profile shows 4.8 from 64 reviews as of September 4, 2026, a solid figure though a modest review count next to the big advertising-heavy Dallas franchises.

Before hiring, ask the questions that matter for this trade in this city. Get the licence number confirmed and check it against the Texas State Board of Plumbing Examiners register. Ask whether the quoted figure is flat-rate or hourly plus parts, and what happens if a wall has to come open. On any sewer or drain job, ask whether a camera inspection is included in the price or billed separately, and ask for the footage. If a section of line needs replacing under a slab, ask whether the plan is a tunnel from outside or a break through the floor inside, because the cost and the disruption differ sharply. On water heaters, ask about the expansion tank, the pan and drain, and whether a permit is being pulled, since Dallas requires one for a replacement.

Compared with the alternatives, Mai Plumbing Co Inc sits in the smaller, referral-fed end of the Dallas market. The large branded companies offer round-the-clock dispatch, financing and membership plans, and they will replace a system readily. A long-standing family shop is generally cheaper on straightforward repairs and less inclined to sell a whole new fixture when a cartridge will do. The trade-off is availability. Weekday-only coverage suits homeowners who can plan, retirees, landlords with a bit of flexibility and anyone who would rather have the same small crew back for the next job.
