Molberg Plumbing is in Flower Mound homes every week, and we work here the same way we’ve worked in Fort Worth since 2018: show up when we said we would, explain what’s actually happening with your plumbing, and fix it right the first time. A dripping supply line, a kitchen drain that won’t clear, a water heater that quit on a Sunday morning, we handle all of it. Our licensed plumbers roll with fully stocked trucks, which means most repairs get finished on the first visit instead of turning into a week of scheduling. And because we live and work in this part of Denton County, we already know the quirks that come with Flower Mound’s mix of 1990s neighborhoods and newer construction off Cross Timbers.
Every service Molberg runs in Flower Mound, on one list. Not sure which? Call it in and describe what it is doing.
From routine repairs to emergencies, Molberg Plumbing is ready to help.

Burst pipes and sewer backups don’t wait for business hours, and neither should your plumber. When you reach our emergency line, we get a licensed tech headed your way, walk you through shutting off water or gas while you wait, and start containing the damage the moment we arrive. Then we talk through your repair options in plain language before anything gets torn out. Flower Mound homeowners call us for slab leaks, failed water heaters, frozen pipe bursts, and main line backups.

Most plumbing problems get worse and more expensive the longer they sit, so we move quickly on repairs. Our team fixes water lines, sewer lines, hose bibs, shutoff valves, pressure regulators, toilets, and anything else in the system that’s leaking, clogged, or running when it shouldn’t. We locate the actual source instead of patching the symptom, then show you what we found before we start work.
Replacing something is often smarter than nursing it along for another year. We install water heaters and tankless units, gas lines for ranges and outdoor kitchens, garbage disposals, sump pumps, sewer lines, water softeners, and every fixture in a kitchen or bathroom remodel. You’ll get a clear estimate up front, and financing is available if the timing caught you off guard.
A little attention once a year keeps small issues from becoming weekend disasters. We flush water heaters, check pressure, inspect supply lines and angle stops, test shutoff valves, and clear buildup out of drain lines before it turns into a clog. Our VIP Membership bundles that maintenance with priority scheduling and ongoing savings for Flower Mound customers.

If your water bill jumped without explanation, or you’re hearing water run when every fixture is off, something’s leaking where you can’t see it. We use infrared cameras, acoustic equipment, and sewer camera inspections to pinpoint hidden leaks under slabs, behind walls, and in yard lines. Once we know exactly where the problem is, we can repair it without tearing up more of your home than necessary.
Slow drains, gurgling toilets, and water backing up into a tub usually mean buildup somewhere in the line. We clear kitchen, bathroom, laundry, and main sewer drains, and we use hydro jetting when grease or scale has coated the pipe walls. Tree roots are a common culprit in Flower Mound’s older neighborhoods, and our camera inspection tells us whether you need a cleaning or a repair.
Our licensed plumbers install, repair, and pressure test gas lines for water heaters, ranges, fireplaces, pool heaters, grills, and generators. If you smell gas, get everyone out of the house and call us from outside. We’ll test the system, find the leak, and make the repair to code so you can use your appliances without wondering.
Sump pumps matter most in homes with basements, crawl spaces, or low-lying lots that collect runoff during North Texas storms. We install new pumps, replace failed ones, and test existing systems so you find out the float switch is stuck before the rain starts rather than after. If your pump runs constantly or never cycles at all, it’s worth having us look.
Expansive clay soil shifts with every dry spell and every heavy rain, and water lines take the stress. We locate and repair leaking service lines, replace failing sections, and run new lines to outdoor kitchens, guest houses, irrigation systems, and workshops. For whole-home repiping, we walk you through the material options and what each one means for pressure, longevity, and cost.

Repairs usually happen on the spot. Bigger jobs get scheduled around you, and every job is backed by our workmanship warranty.

Restaurants, offices, retail spaces, and multi-tenant buildings all have plumbing that has to keep working while customers are in the building. We handle grease line maintenance, commercial water heaters, backflow assemblies, fixture replacement, and emergency repairs, and we schedule around your hours whenever the job allows. Ask us about a maintenance plan that keeps small problems off your operating budget.
Yes. Flower Mound is one of our physical locations alongside Fort Worth and Keller, which means our trucks are already in your area rather than driving in from across the Metroplex when you call.
Yes. We’re a local, family-owned company, started in 2018 by a husband-and-wife team who met at Texas A&M. Our work is led by a Responsible Master Plumber, and there’s no private equity group or franchise office behind us.
Probity is an older word for honesty and uprightness, and it’s the standard we hire and train around. In practice it means we give you the real diagnosis, present every option including the cheap one, and do the work the same way whether or not anyone’s watching.
Yes. Estimates are free, and you’ll know the price before a wrench comes out. If the repair turns out to be larger than expected, we stop and talk with you before continuing.
We do. Repipes, sewer line replacements, and water heater installations can land at a rough time, so we offer financing options that let you get the work done now and pay over time.
Veterans, teachers, and first responders get a discount on service, and our VIP Membership adds priority scheduling and ongoing savings for homeowners who’d rather stay ahead of problems than react to them.
Along with Flower Mound, we work throughout Denton, Tarrant, and Parker Counties, including Highland Village, Lewisville, Grapevine, Trophy Club, Southlake, Keller, and Fort Worth.
