Around the lake. Grapevine Lake and Marshall Creek form much of Flower Mound’s southern edge, and our shop is on the Grapevine side of the water. FM 2499, Long Prairie Road, runs north through the middle of Flower Mound and south to SH 121, which is the road a Flower Mound plumber from our shop normally uses to cross over. Lewisville lies to the east, Highland Village, Double Oak and Bartonville to the north, and US 377 runs along the western edge.
Flower Mound is a town, not a city. For a Flower Mound plumber that changes little beyond whose permit office we call, and it is the largest place on this side of our service area, with close to 76,000 residents at the 2020 census. Most of it is in Denton County, with a small part in Tarrant County. All of it is inside our core area, where the emergency target is a technician on site within 60 minutes. That is a target, so the dispatcher always gives you a real arrival window.
Houses from the 1990s, in large numbers, so most of what a Flower Mound plumber fixes is that decade’s plumbing. That follows from the census rather than a guess: Flower Mound had about 4,400 residents in 1980, about 15,500 in 1990, and more than 50,000 by 2000. A town that more than triples in a single decade is, for the most part, houses from that decade. Growth slowed after the town adopted its SMARTGrowth program in 1999, which is one reason the 1990s stock still dominates.
The town takes its name from The Mound, a hill of about 12 acres near FM 3040 and FM 2499, and the western side sits in the Eastern Cross Timbers. The east side, toward Lewisville, is mostly subdivision lots. The west is more open, and we infer from the larger lots there that water and sewer service lines are often longer, which matters when a Flower Mound plumber is tracing a leak or running a camera to the street.
For a house built in the 1990s, here is what that age means in practice:
Our shop is just across Lake Grapevine. Call for anything leaking or backing up, or book a window online.
Most are on town sewer, but a Flower Mound plumber cannot assume it. The town has a mandatory sewer connection ordinance, and as recently as December 2023 the town council asked staff to look at ways to replace septic systems in one older neighborhood, which tells you some homes still have them. The quickest way to know is your water bill: a sewer charge means you are connected to a main.
It matters to a Flower Mound plumber because the symptoms look alike and the fixes do not. A slow drain or a gurgling toilet on a sewer connection usually points to the house line or a belly in it. On a septic system, the same symptom may be the tank or the field. We start with a camera, follow the line to where it actually goes, and show you the footage. If the problem is a septic tank or drain field, we tell you so plainly rather than selling you a drain job that will not fix it.
Because of the clay and the calendar, slab leaks are near the top of every Flower Mound plumber call list. Blackland Prairie clay swells when wet and shrinks when dry, flexing the slab and the copper inside it, and much of the housing here has had around thirty years of that. The February 2021 freeze added split pipe on top of it.
A Flower Mound plumber from Bulwark locates the leak before cutting anything. We pressure test to confirm which line is losing water, pinpoint the spot with acoustic equipment, and record the location. Then you get options with a written price for each: a spot repair through the slab, a reroute overhead that abandons the failed run, or a partial or full repipe if the same system keeps failing. The signs of a slab leak page lists what to watch for, and leak detection explains the equipment.
A Flower Mound plumber at Bulwark uses one rule of thumb: under about eight years old with a failed element, thermostat or valve, repair it. Past about twelve years, leaking from the tank itself, or rusting at the base, replace it. In a 1990s house the heater may be in the garage, a closet or the attic, and the attic unit is the one that does real damage when it lets go, so a Flower Mound plumber should check the drain pan and its line on every visit.
Hard water is the other half of the story, and the reason a Flower Mound plumber talks about maintenance at every heater visit. Scale settles in tank bottoms and coats tankless heat exchangers, and flushing or descaling on a schedule is the cheapest way to make the next heater outlast the last one. Our water heater repair and replacement page covers tank and tankless, and if yours is leaking now, read whether to repair or replace a leaking water heater.
The everyday list, which a Flower Mound plumber does the same way as the large jobs:
You call (817) 677-9010, a person answers at any hour, and a Flower Mound plumber is dispatched from the Grapevine shop with an arrival window you hear on the call. The core area target is 60 minutes. While you wait for your Flower Mound plumber:
For after hours and weekend calls in general, see the 24/7 emergency plumber page.
Every Flower Mound plumber job gets a written flat price before any work starts, not a published number, because the job decides the price. The diagnostic fee is quoted on the phone before anyone is sent and credited in full if you go ahead. After hours, weekend and holiday rates are disclosed on the same call, and permits are pulled where the town requires them. Labor on a Flower Mound plumber job carries a 1 year warranty as a baseline, 2 years on water heater and fixture installs, and 3 years on repipes and sewer or water line replacement, with manufacturer warranties registered in your name.
Whoever you hire, make sure the Flower Mound plumber at your door works for the company you called. Ours are Bulwark employees working under TSBPE license 47173. We do not subcontract and we do not sell leads.

From our shop at 720 Industrial Blvd in Grapevine, on the south side of Lake Grapevine. Flower Mound is on the north side, and FM 2499 connects the two by way of SH 121. Flower Mound is inside the core area where the emergency target is a technician on site within 60 minutes, and the dispatcher gives you a real arrival window on the call.
Most homes in town drain to a town sewer main, but not all of them. The town has a mandatory sewer connection ordinance, and some older properties are still on septic. Your water bill is the quickest check: a sewer charge on it means you are connected. If you are not sure, a Flower Mound plumber can locate the line with a camera and tell you where it goes.
The water heater, if it is original or close to it, and the copper under the slab. The town grew from about 15,500 people in 1990 to more than 50,000 in 2000, so a great many houses are from that decade. A Flower Mound plumber sees both the slab plumbing and any untouched water heater from that decade reaching the age where failures start.
Pressure testing first, to confirm which line is losing water, then acoustic equipment to pinpoint the spot. The location is recorded before anything is cut, and you get a written price for each option, including a reroute overhead where that makes more sense than opening the floor.
Yes, where the town requires them: gas work, sewer replacement, repipes and water heaters are the usual ones. Your Flower Mound plumber pulls the permit and meets the inspector, and the permit is part of the written price.
A technician employed by Bulwark Plumbing, working under Texas license 47173, Responsible Master Plumber Jared J. Allen. We do not subcontract, and your call is never sold to another company as a lead.
Yes. The small Tarrant County part of town is served the same way, and so are Lewisville, Highland Village, Double Oak, Bartonville, Trophy Club, Grapevine, Southlake and Coppell, along with the rest of the 52 cities in our service area.
