Questions and Answers

A toilet in my Harlingen home is constantly leaking at the base. What's usually the cause and how can Guillen Plumbing fix it?

A leak at the base of your toilet is often due to a failed wax ring seal, which is common in older homes. This seal can wear out over time, allowing water to seep onto your floor and cause damage. Guillen Plumbing will first inspect the area to confirm the issue. Our repair involves safely removing the toilet, cleaning the flange area, and installing a new, high-quality wax ring before resetting the toilet to ensure a watertight seal and prevent future leaks.

I suspect an old pipe is leaking behind my wall. What should I do, and what services do you offer for this common Harlingen problem?

If you suspect a hidden leak, it's important to act quickly to prevent mold and structural damage. Turn off your main water supply and contact us immediately. Guillen Plumbing specializes in pinpointing leaks with non-invasive inspection techniques. For old pipe leaks, we offer precise water pipe repair or replacement. We can access the problem area with minimal disruption, replace the damaged section with durable modern piping, and ensure your system is restored to proper pressure and function.

My shower drain is very slow, and I'm worried about a bigger sewer issue. Can you help diagnose and resolve this?

Absolutely. A slow-draining shower can be a simple clog or a symptom of a deeper problem in your main sewer line, especially in homes with older plumbing. Guillen Plumbing starts with a thorough drain inspection and cleaning. If the issue persists, we can perform a sewer line camera inspection to identify any cracks, root intrusion, or bellies in the line. Based on what we find, we provide clear options for repair or sewer installation, using trenchless methods when possible to save your yard and get your drainage flowing smoothly again.
