Highline Plumbing Llc.

Highline Plumbing Llc handles plumbing work in Harlingen. Nathan runs the crew and takes on jobs such as fitting anti-siphon valves on sprinkler systems, swapping out cracked brass ball valves, putting in tankless water heaters after old units fail, and replacing standard hot water heaters on short notice. The same crew also sets up floating vanities with sinks, installs freestanding tubs, places new toilets, runs lines for walk-in showers, and fixes leaks that show up after other work. The business lists its address at 1124 Council Way and keeps regular weekday hours from 7:30 to 5:30 while staying closed on weekends.

Customers report calling for non-emergency valve work and getting a prompt slot without long waits. Nathan reached out directly to set times that fit the homeowner and arrived when promised. One job involved a water heater replacement finished quickly with the area left clean. Another covered a full list that included a tankless heater, two vanities, a large tub, toilets, and shower plumbing, all handled in one visit. Reviewers noted the crew charged fairly even when the leak was not from their earlier work.

Nathan and the crew stay in touch by phone to confirm arrival windows and finish each task with solid parts that hold without leaks. They keep the site tidy once the work ends and bill at rates described as competitive for the scope. Service stays within the listed hours on weekdays, and the crew handles both planned replacements and same-day calls when equipment breaks.

The business holds a 5 rating across its six reviews. Reviewers keep mentioning fast scheduling, clean results, and reasonable costs for the parts and labor. DIRT Score 3.3 from 6 reviews on Finds.

“I called Highline Plumbing twice in the past several weeks. The first was to install a new anti-siphon valve for a lawn sprinkler system. The second was to replace a cracked 1" brass ball valve (faulty because of no-lead brass manufacturing problems several years ago). Although I told them that neither situation was an emergency, they scheduled me for prompt service. The plumber called me to ask when would be a good time for him to perform the work and we scheduled the job. He showed up on time. He used high quality components in both situations and both jobs were leak-free. I was present during the valve replacement and the plumber showed me his new device that makes solder-free connections that are much faster, more reliable, and less risky because no torch is involved. And the price was fair!! I'll recommend HIghline Plumbing to everyone who needs a quality job. ** I seldom take the time to write a review - but these folks really deserved it!”

“Just wanted to thank Nathan and his crew for replacing my hot water heater on short notice. They where professional and cleaned up after themselves after the job was finished. It was as if they where never there. Thank you.”
