We cut this one out of solid granite.

An 18-ton excavator, a jackhammer, and a hilltop nobody else would quote. Thirty-five years, one family, and Bob Mellon still on the job site.

★ 4.6 from 108 Google reviews, a BBB A+ rating, CSLB #986598, and a Master Pools Guild membership — earned the slow way, one Valley backyard at a time since 1989.

The hard part

Most builders show you the water. We'll show you the rock.

The hilltop job came with a view in every direction and bedrock under every inch of it. It took an 18-ton excavator with a jackhammer to open the hole — then a waterfall, a slide, laminar jets, bubblers, a sunken fire pit and a custom pebble interior went in on top of it.

That is the job most companies pass on. It is also the reason a homeowner on a hillside in Auberry or Oakhurst calls us instead of a franchise with a call center. We have been digging into the east side of this valley for thirty-five years, and we know what is under it.

Who you actually get

Our customers don't review a company. They review three people by name.

Owner Bob Mellon

Started pouring concrete in Fresno in 1979, started this company in 1989, and still answers the phone. He walks the site, he takes the change order, and his name is on the license.

Design Jeremy Pope

Draws your pool and puts it in 3D before a shovel moves, then sits down with you over tile and pebble finishes until it is the one you want.

Project coordination Heather

Keeps the schedule and tells you what is happening next week — the part every review mentions and most builders skip.

The rest of the family Nikki, Travis & the crew

A niece who designs, a brother-in-law in sales, sons in operations, and Bob's wife on the books. It is a family company in the literal sense.
