Plumbing Services for Your Home
Plumbing problems come in all shapes and sizes. Sometimes it’s a clogged drain or a leaking faucet. Other times, it’s a damaged sewer line, a slab leak, or a pipe that needs to be replaced. Our team has the experience and equipment to handle both.
We offer after-hours plumbing service, plumbing inspections, and residential plumbing remodeling. We can also take care of appliance and plumbing system installations, including dishwasher installation, garbage disposal installation and repair, water filtration systems, and water softener installation and repair.
Drain, Sewer & Pipe Repairs
Some plumbing problems aren’t easy to see. A leak may be behind a wall, underneath a slab, or somewhere along your sewer line. We’ll work to find the source of the problem and explain your options before moving forward with the repair.
Our drain, sewer, and pipe services include backflow testing, burst pipe repairs, clogged drain cleaning, leak detection, pipe replacement, repiping, sewer line repair and cleaning, tunnel jobs, slab leak repair, and water main replacement.
Fixtures, Gas Lines & Water Heaters
Need to replace an old fixture or repair something that’s stopped working properly? We install and repair faucets, showers, sinks, sump pumps, and toilets.
Our plumbers also handle gas line installations and repairs, as well as traditional and tankless water heaters. Whether your water heater needs a repair or it’s time for a replacement, we can help you figure out which option makes the most sense for your home.
Straightforward Service From an Experienced Team
Nobody wants to spend their day dealing with a plumbing problem. We try to make the process as simple as possible with fast quotes, up-front pricing, and clear explanations of the work we recommend.
Marathon Plumbing is certified by the Texas State Board of Plumbing Examiners and fully insured. More importantly, our team understands that we’re working in your home or on your property. We take that responsibility seriously and want you to know what we’re doing, why we’re doing it, and what it will cost before the work begins.
