Best Plumbing in Arlington, TX — 11 Vetted Contractors

Yes. The City of Arlington requires a permit for water heater replacements, and the installation must be inspected. This applies to both tank and tankless units. Your licensed plumber should pull the permit as part of the job — it's typically $50–$100 and is included in most reputable contractors' quotes. Skipping the permit is common but creates problems when you sell: unpermitted work can kill a real estate transaction or require expensive after-the-fact remediation.

The most reliable early signs in an Arlington home are: an unexplained increase in your water bill (sometimes $50–$200/month above normal), warm or hot spots on your floor (for hot-water-line leaks), the sound of running water when all fixtures are off, or cracks appearing in flooring or baseboards. Arlington's clay soil movement can mask or mimic some of these symptoms. If you suspect a slab leak, call a plumber who offers electronic leak detection — don't let anyone start breaking concrete until the leak is precisely located.

Most Arlington-area plumbers charge a $75–$150 diagnostic or service call fee to come out and assess the problem. Many waive this fee if you proceed with the repair. After-hours and weekend emergency calls typically carry a premium of $50–$150 on top of the base rate. Always ask upfront whether the service call fee is credited toward the repair cost — reputable shops usually say yes.

Probably worth a professional assessment, yes. Homes built in the 1970s in Arlington frequently have galvanized steel supply lines (which corrode from the inside, reducing flow and eventually failing), cast-iron drain lines (which corrode and can partially collapse), and copper supply lines embedded in slabs that have now experienced 50+ years of Arlington's clay-soil movement. A camera inspection of your drain lines ($150–$300) and a plumber's walkthrough of your supply system can tell you what you're actually dealing with before something fails catastrophically.

Go to tsbpe.texas.gov and use the license lookup tool. You'll need the plumber's name or license number. The Texas State Board of Plumbing Examiners (TSBPE) maintains a public database of all active, expired, and disciplined licenses. This takes under a minute and is the single most important check you can do before hiring. Ask the plumber for their license number before they arrive — any legitimate pro will give it to you without hesitation.

Yes, Arlington's water is moderately hard — typically in the 150–200 mg/L range (as calcium carbonate), depending on the seasonal source blend from the Trinity River Authority and Tarrant Regional Water District. That mineral load accelerates scale buildup in water heaters, reduces the lifespan of appliances, and can restrict flow in older fixtures. A water softener or a whole-house filtration system can help, but discuss sizing with a licensed plumber — oversized softeners create their own problems.

First: shut off the main water supply. In most Arlington homes, the shutoff is near the street at the meter box or inside near the water heater. Then call a licensed plumber — most Arlington-area shops offer 24/7 emergency service, though expect a premium. Document the damage with photos before any cleanup for insurance purposes. If the burst is related to a freeze event (like Winter Storm Uri in 2021), check whether your homeowner's policy covers sudden pipe failures — most standard policies do, but coverage for the resulting water damage varies.

For a standard Arlington ranch home in the 1,500–2,200 sq ft range, a full repipe from galvanized to PEX typically takes 2–4 days. That includes the rough-in, drywall patching (sometimes subcontracted), and the city inspection. You'll be without water for portions of the work days but usually not overnight. Larger homes or two-story layouts add time. Get a written timeline in the contract — vague completion dates are a common source of disputes.
