The hall bath has leaked twice this year, both times from the same wall it shares with the kitchen. Or you just bought a Midway Hollow ranch, the inspector flagged galvanized pipe, and you want to know what you’re in for before the drywall goes back up. Around Love Field and Bachman Lake, most of the houses are compact, and the question is rarely whether to do something. It’s how much.
Fullbore Dallas Repiping replaces water supply lines in Northwest Dallas homes and small commercial spaces, from one bathroom group to the whole building. We price a targeted partial repipe next to a whole-house repipe so you can see the difference in writing, and our guide on whether to repair or repipe explains how to weigh them.
Small house, smaller job
Size works in your favor here. A compact ranch has fewer fixtures and shorter runs, so a whole-house repipe needs fewer drops and fewer wall openings than in a big house. On a slab, we run the new lines overhead through the attic and down interior walls. On pier-and-beam, the crawlspace gives us another route and keeps more walls closed.
The work follows a simple order. We run the new lines through the attic and drop them to each fixture while the old system stays in use. Then the water goes off for the cutover: the new system is tied in at the main and the water heater, pressure tested and flushed, and the old lines are cut out of service. How long you’re without water depends on the house, and we put it in writing.
Repair one bathroom or do the whole house?
When the trouble is confined to one group, such as a hall bath and kitchen on a shared wall, replacing just those branches can make sense. But in a compact house, the extra cost of the remaining lines is often small next to the setup, permit and restoration you are already paying for. If the trunk feeding that bath is the same tired pipe, new branches still draw through old pipe. We trace what feeds the problem area before drawing a boundary.
Galvanized, polybutylene or both
Older ranches here may still have galvanized steel, which narrows from the inside and sheds rust when the water has been sitting. Houses from the 1970s and later may have polybutylene or CPVC beside copper. Our guide on identifying water pipe material shows where to look at the heater and under sinks. Additions are worth a second look: a room plumbed decades after the house can carry a different material from the rest.
Shops, offices and apartment buildings
A shop, office or restaurant along Stemmons or Northwest Highway needs work planned around business hours, and the lease may say who owns the plumbing. Our commercial repiping page covers that scope. Older apartment complexes near Bachman Lake raise a different issue: where a 1960s or 1970s building has no shutoff for each unit, even a small branch repair means turning off a whole stack. Our apartment and condo repiping page explains how unit valves and staged work help, and the guide on repiping water shutoffs covers notice and timing.
Every one of these is permitted plumbing work. The permit goes in through DallasNow, the City inspects the new pipe at rough-in, and a final inspection closes it out.
Neighborhoods in Northwest Dallas
Love Field
The area around Dallas Love Field, mainly ZIPs 75235 and 75209, mixes older single-family streets with newer apartment buildings and commercial property tied to the airport and the Medical District. In a newer building, a leak usually calls for finding the one failed fitting before anyone talks about a repipe. In an older house, the material question comes first. Small office and clinic buildings here need restroom shutdowns scheduled around patients and staff.
Midway Hollow
Midway Hollow is known for compact postwar ranches on modest lots. Where a house still has original galvanized pipe, a whole-house replacement is usually the cleaner choice, and our galvanized pipe replacement page explains what that involves. Where a house has been partly repiped or enlarged, we ask which lines are original, because an addition plumbed decades later can carry a different material from the rest of the house.
Northaven Park
Northaven Park sits farther north, near Northaven Road and Webb Chapel Road, with mostly single-family streets. Houses from the 1970s or later may have polybutylene or CPVC alongside copper; our polybutylene pipe replacement page explains what to look for. Where a long hot line runs from a garage heater, a hot water line replacement is a narrower scope worth comparing.

The numbers behind the neighborhoods
The Census Bureau’s 2020-2024 American Community Survey estimates show three similar ZIPs and one outlier. ZIPs 75209, 75220 and 75234 all have median build years of 1977 to 1978, with about half their units built before 1980. ZIP 75235, around Love Field and the Medical District, has a 2002 median and 57.0% of units in buildings of 20 or more units.
Since January 2024, City of Dallas open data shows 7 permit records in these ZIPs that explicitly describe interior water-supply repiping. The City’s ForwardDallas plan describes the NW-3 planning district as mostly residential, with commercial and mixed-use development along I-635 and Forest Lane. Block by block, though, a 1950s ranch near Bachman Lake and a 2000s unit near the Medical District need very different plans.
Dallas Water Utilities treats surface water with chloramine and corrosion control, and a December 2023 City memo puts hardness at 120 to 155 mg/L as calcium carbonate. That builds scale in water heaters and aerators; it is not a cause of pinhole leaks on its own.
How we put a price on it
We price after the first visit, from the fixture count, attic or crawlspace access, the existing material, the water heater and valves, and how much wall and ceiling we restore. The repiping cost estimator explains those drivers, and our guide on repiping old homes covers the choices that come up in older ranches. The water service line from the meter to the house is a separate scope from ours.
