Houston’s older neighborhoods such as the Heights and Montrose contain many 1940s–1970s homes still carrying original galvanized steel supply lines. These pipes corrode faster in the area’s humid subtropical climate, where constant moisture inside walls accelerates rust and scale buildup. Whole-house repipe work here typically means running new PEX or copper mains through attics and crawl spaces to avoid disturbing plaster or brick exteriors common in River Oaks and Midtown.
Harris County soil shifts with seasonal rains and the mild winters that never fully freeze the ground. This movement stresses rigid pipe joints, so crews anchor new lines with expansion loops and secure straps every four feet. Downtown and Midtown high-rises add another layer: limited chase space and shared walls require coordinated shut-offs and temporary bypass lines so neighboring units stay in service during the job.
Katy, Sugar Land and Pearland customers often request repipes after repeated pinhole leaks appear in laundry rooms or behind showers. Because summers stay hot and humid, crews insulate all new hot-water lines to prevent condensation dripping onto drywall and to maintain energy efficiency in unconditioned attics.
Access is the biggest variable. Slab homes in Pearland may need tunneling under driveways, while pier-and-beam Heights houses allow easier attic routing. Every project starts with a camera inspection of existing lines to map exactly which branches must be replaced versus which can remain.
Technician insight
In Houston the thing that catches most people out with whole-house repipe is how the heavy clay soil in Harris County keeps shifting even in mild winters, so any new rigid pipe that isn’t properly strapped will develop leaks at the joints within a couple of seasons.
Heights Bungalow Galvanized Failure
A 1950s Heights home showed low pressure and brown water after heavy spring rains. Camera inspection found multiple pinholes in the original galvanized lines under the pier-and-beam floor. We ran new PEX mains through the attic, tied into existing fixture branches, and restored ceilings the same week. Water pressure returned to normal and the homeowner reported no more staining.
Whole-House Repipe Services We Offer
✓Galvanized Pipe Replacement
Full removal of corroded galvanized lines and installation of new PEX or copper throughout the home to restore water pressure and eliminate rust discoloration.
✓PEX Repiping
Flexible PEX tubing routed through attics and walls to minimize demolition while providing corrosion resistance suited to Houston’s mineral-rich water.
✓Copper Repiping
Traditional rigid copper lines installed where homeowners prefer metal durability and where attic temperatures stay high during summer months.
✓Slab Home Repipe
Tunneling and manifold placement under concrete slabs common in Sugar Land and Katy to avoid cutting finished flooring.
✓Attic Line Reroute
Relocation of supply lines into conditioned attic space in Heights and Montrose homes to reduce wall demolition and improve future access.
Whole-House Repipe Cost in Texas
| Service | Typical Range | What Affects It |
|---|---|---|
| Whole-house repipe, single-story Heights or Montrose home | $6,800–$9,200 | Attic access reduces labor; number of bathrooms increases fixture count. |
| Whole-house repipe, two-story River Oaks or Midtown home | $9,500–$13,000 | Additional floor adds wall penetrations and longer runs. |
| Slab tunneling add-on, Pearland or Katy | $2,400–$4,100 | Depth of slab and driveway restoration affect final cost. |
| Copper upgrade instead of PEX | $1,800–$3,200 | Material premium and soldering time in hot attics. |
