If you are a homeowner or business owner in Highland, we would be glad to help and to treat your home or business like our own. We answer the phone 24/7 at (909) 312-4516. Highland's 1970s-90s tract neighborhoods bring regular slab leak detection calls. The older neighborhoods around Palm Avenue have plenty of galvanized supply lines due for a repipe and aging cast-iron drains. East Valley Water District water is hard, so salt-free water softeners and water heater anode rod service are frequent requests. Water pressure runs high across Southern California, which shortens fixture life and wears out pressure regulators, so regulator service is a common call here too.

Rural and newer homes at the east end of town. Water heater and pressure regulator work.
Highland began as a citrus townsite around 1891, served by the Santa Fe Railway that hauled out its oranges and lemons; the old Palm Avenue area is a National Register historic district of early citrus-town homes and packing houses. The city incorporated late, in 1987. Today the housing runs from those historic pockets to 1970s-90s tracts in central Highland, newer 1990s-2000s construction in East Highlands Ranch, and custom homes in the foothills above.
Most of Highland is served by the East Valley Water District. The water is hard, meaning scale and heater sediment are a fact of life here. Incoming pressure runs high, as it does throughout the region, so pressure regulators matter.

In Highland's older homes, the sewer laterals are often cast iron or clay, with root intrusion. Cable for blockages, hydrojet to clear roots and grease. Camera inspection on every main line.
Repiping is common where Highland's older homes still have galvanized supply lines. We repipe in PEX or copper, phase the work and patch any drywall we open.
We work on cast-iron, clay, ABS and PVC sewer lines in Highland. Trenchless pipe bursting and pipe lining when the line allows, which can save the yard and the driveway.
