We serve Cupertino's established neighborhoods: Monta Vista — the area's first tract, dating to the 1940s — Rancho Rinconada with its 1950s Stern & Price "Miracle Houses" designed by Cliff May, Garden Gate, Homestead Villa, Oak Valley, and the Faria/Jollyman area.
Slab Leak Repair in Cupertino
The classic signs: a warm spot on the tile, carpet damp along a baseboard, a water bill that jumps $50 for no reason, or the faint sound of running water with every fixture off. Hot-water lines fail first — heat accelerates the corrosion that eats copper from the inside. We confirm the leak's location electronically, then either open a small section of slab for a direct repair or reroute the line overhead, abandoning the buried run entirely.
Rerouting costs more than a spot repair but ends the problem for good in homes where all the under-slab copper is the same age. One leak in 50-year-old pipe is a warning; the next one is already forming.
Repiping and Water Heaters
Many Cupertino ranch homes still run original galvanized or early copper supply lines. If your water pressure has faded year after year or the water runs discolored each morning, the pipes are telling you they're done. A whole-home repipe — typically two to four days — restores full pressure and clean water, and we keep disruption minimal by fishing lines through attics and wall cavities.
Water heaters in these homes often sit in garages or exterior closets past their prime. We install high-efficiency tank and tankless units sized to the household, and haul the old unit away.

Frequently Asked Questions
**How much water can a slab leak waste?**
A pinhole leak can lose hundreds of gallons a day — enough to show up fast on your San Jose Water bill and to saturate the soil under your foundation. That's why a sudden unexplained bill increase is the most reliable early warning.
Will finding the leak destroy my floors? No. Electronic locating pinpoints the break within inches, so we open only a small section of slab. Most homeowners are surprised how contained the repair is — one neat patch, not a torn-up room.
Should I repair or reroute a leaking under-slab line? If the pipe is 40–50 years old and this is the first leak, expect more. Spot repair fixes today; rerouting through the attic abandons the entire aging run. We show you both options with honest pricing and let you decide.
How long does repiping a Cupertino ranch home take? Most single-story ranch repipes finish in two to three days. We keep water on each evening, patch openings as we go, and coordinate so your household routine barely notices the work.
