Yes — Gilbert is within our Phoenix metro service area. Our nearest location is in Mesa. We offer free in-home water testing and same-week installation in most cases.
Water softeners for Gilbert homes start at $1,945. Our three most-installed systems are Olympus On-Demand from $1,945, Sanitech Pro-Line from $2,645, Pantora Dual-Stage from $4,145. Most Gilbert homes need a 48K or 64K grain system depending on household size and hardness (18-22 GPG here); sizing on our entry system runs 32K from $1,945, 48K from $2,145, 64K from $2,345. We confirm the right size with a free in-home water test. Every softener is backed by a 10-Year Part & Labor Warranty. Installation is quoted separately and starts at $250 for a standard installation to an existing softener loop. 0% APR financing for 9 months is available.
Most Gilbert installations are finished in a single visit — a few hours when the home already has a softener loop, longer when we need to run a new line. We confirm the scope during your free in-home water test so there are no surprises on install day.
Many newer Gilbert homes are pre-plumbed with a softener loop, which makes installation faster and less expensive. Older homes without a loop need a full line run to the main. We quote both options up front — see our loop vs. full-line guide for what to expect.
At 18-22 GPG, Gilbert water is hard enough that most homeowners want true softening. Salt-free conditioners reduce scale without removing hardness minerals, so they fit homes on septic or anywhere brine discharge is a concern. We recommend one or the other based on your water test, not a sales quota.
Mainly salt. Our Smart Salt Delivery program monitors your brine tank and delivers salt automatically, and our technicians service systems across Gilbert and the Phoenix metro. Beyond salt, a properly sized system needs very little attention.
