West Houston water is hard, and it shows up as scale on fixtures, spotty glassware, dry skin and shortened water-heater life. A softener protects the plumbing you've already paid for. We'll tell you honestly whether your home would benefit.
Shut off the main water valve to the house first, then call us. If you're not sure where your shut-off is, call anyway and we'll talk you through finding it while we're on the way.
