The problem
Hard water is quietly costing you money
Calcium and magnesium don't just leave spots on your glasses. They build up inside every appliance and pipe in your house, and they shorten the life of all of them.
Your shower
Blocked nozzles, weak spray, and skin and hair that never quite feel clean.
Your water heater
Scale coats the element, so it burns more energy to heat the same water — and fails sooner.
Your pipes
The bore narrows year after year. You feel it as pressure loss long before you see it.
How it works
One system. Every tap in the house.
Nick walks through exactly what the system does and why it costs what it costs. Under a minute.
-
Water enters the tank
Every drop coming into your home passes through the system before it reaches a single tap.
-
A bed of resin grabs the minerals
The resin holds onto the calcium and magnesium responsible for hard water, and swaps them out.
-
Soft water, everywhere
No more scale buildup, no more spotty dishes, no more dry skin and hair.

Why Graystone
A small business doing one thing properly
Softer skin and hair
Soft water rinses properly, so soap and shampoo come off instead of drying on you.
Cleaner dishes and clothes
No more cloudy film on glassware, and detergent that actually does its job.
Appliances that last
Scale is what kills water heaters, dishwashers and washing machines early. Take it out.
Water worth drinking
The reverse osmosis filter comes free, so the water at your kitchen tap is the best in the house.

Nick
Sales & Marketing
Hey, I'm Nick! I've been in the water game for 4 years, starting with window cleaning using the same purified filtration systems now going into people's homes. We kept seeing homeowners charged $5,000–$8,000 for a system that should cost around $3,250, so we built Graystone to fix that. I lead sales & marketing at Graystone, and in my free time you can catch me on the golf course.
Sean
Field Operations
I'm Sean! I've spent 4 years in the water treatment industry. I started as a commission sales rep and worked my way up to hands-on installation. I've completed 100+ full home water softener, whole-home filter, and reverse osmosis installations. I lead Field Operations at Graystone, and on weekends you'll catch me firing up the BBQ with my kids.

Our work
What it looks like in your basement
A finished Graystone install
Mineral tank, brine tank and bypass, plumbed into the main line before it reaches the rest of the house. Tucked into the corner beside the water heater, out of the way, on a footprint about the size of a kitchen bin.
- Fitted to the main line, so every tap in the house is covered
- Bypass valve fitted as standard, so the house still has water during service
- We walk you through running it before we leave
FAQs
Common questions answered
A whole-home water filtration and softening system — 48,000 grain capacity, 27 GPM — a multi-stage reverse osmosis drinking filter fitted under your kitchen sink, and professional installation of both. That is the full price; there is no separate install charge.
We're a small family business, not a franchise. There's no regional office, no commission-only sales team and no national advertising budget priced into your quote. The equipment is the same class of system the franchises charge $5,000–$7,000 to install.
Water coming into your home passes through a bed of resin inside the tank. The resin grabs onto the calcium and magnesium that make water hard and swaps them out, so what reaches your taps is soft water. That's what stops the scale, the spotty dishes and the dry skin.
A correctly sized system shouldn't noticeably change your pressure. Scale buildup inside old pipes is far more likely to be what's costing you pressure, and softening stops that getting worse.
Yes. The reverse osmosis drinking system goes in under your kitchen sink with its own tap, at the same visit, at no extra cost. Sediment pre-filter, twin carbon blocks, the RO membrane, a coconut-shell carbon polish and an alkaline filter. Most companies sell it as an add-on.
Yes — we'll need access to your main water line and to the cabinet under your kitchen sink, and we'll walk you through operating the system before we leave.
Roughly an hour's drive from St. Louis in any direction. That covers St. Louis City and County, St. Charles County, Jefferson County, Franklin County, the Illinois Metro East across the river, and the southern edge of Lincoln and Warren Counties. The full town list is at the bottom of this page — if you don't see yours, call and ask, because the edge of the map moves depending on where we're working that week.
A lifetime warranty on the system's dry parts — the mechanical components that never touch water. Five years on the control valve, circuit board and filtration media, and one year on our labour from the date of installation. Separately, the manufacturer backs the media and storage tanks and the ceramic discs for life, control valves and media for five years, and the RO system for one. You get the full written statement with your install, and it's on this page as the warranty statement.
Not yet — we're a young business and our Google Business Profile is still being verified. We'd rather tell you that than pad the page out. What we can give you instead is the written warranty, a fixed price, and the name of the person who'll be doing the work. If you'd like to speak to someone whose system we've already fitted, ask and we'll put you in touch.
