The plumbing installed in most Leander new-construction homes is spec-grade builder plumbing: mixed-brand fixtures, minimum-code sizing, and CSST gas lines that often need bonding correction. Those systems typically make it through the 1-year builder warranty, but the failures start immediately after — dripping shower valves, running toilets, garbage disposal jams, dishwasher supply-line drips, and water heaters throwing error codes.
Crystal Falls Plumbing specializes in post-warranty fixes for Leander's newest communities. We know exactly which fixtures the major builders (Lennar, DR Horton, Pulte, KB, Perry, Highland, Ashton Woods) used in each phase, which failures are common, and how to upgrade to a mid-grade or better fixture that will actually last. We also handle full rough-in and trim-out for additions, remodels, and custom builds.
Common New-Construction Plumbing Problems
If your home is 1–5 years old in Leander, these are the most common calls we run.
- Shower valve drips or won't get hot
- Toilet keeps running or refills randomly
- Water heater short-cycles or throws an error code
- Garbage disposal jams or leaks at the drain
- Faucet cartridge fails from hard-water scale
- Yellow CSST gas line missing proper bonding
- Ice-maker supply line dripping behind fridge
How We Handle Post-Warranty Work
- 1. Home Walkthrough
We inspect every fixture, water heater, softener loop, gas connection, and hose bib and give you a written list of issues sorted by urgency.
- 2. Warranty Review
If you're still inside the 1-year builder warranty, we tell you what should be filed with the builder before you pay us. Honest first, billing second.
- 3. Repair Recommendations
For each issue we recommend repair vs. upgrade, with a mid-grade or better replacement option that will actually last in Leander's water.
- 4. Execute & Warranty
Repairs are performed with genuine parts, permit pulled if required, and every replacement carries our 2-year workmanship warranty.
What Our New-Construction Plumbing Services Include
- Rough-in for slab-on-grade or pier-and-beam: PVC drain-waste-vent, PEX-A supply from a manifold, and gas rough-in coordinated with the framing schedule
- Trim-out: every fixture set, tested, and photographed with model + serial documented for the homeowner warranty file
- Builder-warranty fixes on 1-2 year-old Leander homes where builder-grade materials are already failing (typically water heater expansion tanks, T&P valves, angle stops, and disposal splash guards)
- Post-warranty upgrades: replace builder-grade tank heater with a matched softener + expansion tank, upgrade builder-grade fixtures, add water hammer arrestors, add a bypass loop for a future softener
- Water-hardness assessment on every new-build — most Leander builders don't include a softener and the tank heater warranty is already ticking
- Permit-pulled work under our RMP license with closed City of Leander inspection records
What Affects the Price
New-construction repair pricing depends on which fixture, which brand, and whether repair or replacement is the right call.

Serving Leander & Williamson County
Travisso, Bryson, Crystal Falls, Mason Hills, and Summerlyn have all seen buildout in the last 5–15 years, and the plumbing failures we see in each community follow the fixture-mix patterns of the builders who worked those neighborhoods. We keep a running note of which fixture brands appear in each phase so we walk in with the right cartridges and rebuild kits — no second visit for parts.
