Best Plumbing in Arlington, TX — 11 Vetted Contractors

Yes. Per the City of Arlington Development Services, water heater replacements require a plumbing permit. Your licensed plumber should pull this permit before the work begins — it's included in most professional installation quotes. An inspection will follow to confirm the installation meets code. If a contractor tells you a permit isn't needed for a water heater swap in Arlington, that's a red flag. Unpermitted installations can create problems with your homeowner's insurance and at resale.

The most common signs are: an unexplained increase in your water bill (sometimes 30–50% higher with no change in usage), the sound of running or hissing water when all fixtures are off, warm or damp spots on your floor, and in severe cases, visible cracks in flooring or baseboards. Arlington's clay soil movement makes slab leaks more common here than in many other Texas cities. If you suspect one, a licensed plumber can perform a pressure test and use electronic leak detection equipment to pinpoint the location before any concrete is touched.

As of June 2026, most Arlington plumbers charge a $75–$150 diagnostic or service call fee to come out and assess the problem. Some waive this fee if you proceed with the repair. Emergency after-hours calls — nights, weekends, holidays — typically carry a surcharge of 25–50% on top of standard rates. June is peak season for emergency calls in DFW, so if your issue isn't urgent, scheduling during business hours on a weekday will save you money.

Go to tsbpe.texas.gov and use the license lookup tool — it's free and public. Search by the individual's name or license number. You want to confirm the license is active, the license type is at least Journeyman (Master Plumber if they're running the job or pulling permits), and there are no disciplinary actions on record. Per the Texas State Board of Plumbing Examiners, all plumbers working for compensation in Texas must be licensed. This takes about 60 seconds and is worth doing before anyone touches your pipes.

Possibly, yes. Homes built before roughly 1980 in Arlington frequently have galvanized steel supply lines, which corrode from the inside over decades. Symptoms include gradually declining water pressure, discolored water (rust-colored, especially first thing in the morning), and visible corrosion at exposed pipe sections. A plumber can do a quick visual inspection and pressure test to assess the condition. If galvanized pipe is confirmed throughout the house, whole-house repiping with PEX or copper is the long-term fix — typically $4,000–$12,000 depending on home size.

Yes. Arlington Water Utilities data shows the city's water supply is moderately hard, typically in the 150–250 mg/L range as calcium carbonate. Over time, this mineral load creates scale buildup inside tank water heaters (reducing efficiency and lifespan), clogs aerators and showerheads, and can narrow supply lines in older homes. Annual water heater flushing helps. A whole-house water softener is a meaningful investment for homes with older plumbing or if you're replacing appliances and want to protect them.

Texas law allows homeowners to perform plumbing work on their own primary residence without a license, but permits may still be required depending on the scope of work. Per TSBPE rules, the exemption applies only to the homeowner personally doing the work — not a friend, family member, or handyman working for compensation. For anything beyond a simple faucet swap or toilet replacement, pulling a permit and having the work inspected protects you legally and at resale. For complex work like slab repairs or repiping, hiring a licensed Master Plumber is strongly advisable regardless of the legal option.

June is the busiest month for plumbers in the DFW market. For non-emergency work, expect scheduling windows of 3–7 business days with most established companies. Emergency services (active leaks, no hot water, sewage backup) are typically available same-day or next-day but at premium rates. If your issue is urgent but not a true emergency, calling early in the week and being flexible on time windows will get you faster service. Having 2–3 plumbers' numbers on hand before you need them is the best preparation.
