North Bay Ponds
Pond building, rebuilding and upkeep for Napa Valley gardens, with koi and aquatic plants, led by Jesus Avila.
Acerca de
Napa's gardens and winery courtyards are full of ponds, fountains and streams, and each one eventually needs a pump replaced, a liner patched or its fish looked after. North Bay Ponds, with Jesus Avila as president, was listed at 4093 Jefferson Street on the north side of Napa. Current directory listings show a trading name of North Bay Ponds & Water and a different Napa address on H Street, with the same phone number, so confirm where the business is before you drive over. This page was compiled from public business records and is waiting for the owner to confirm it.
What pond builders in Napa County usually do
Directory listings describe pond construction, rebuilding and maintenance, along with koi, goldfish and aquatic plants. A business of this kind usually designs and digs new ponds, installs liners, pumps, skimmers and biological filters, builds streams and waterfalls from boulders, and rebuilds older ponds whose liners or plumbing have failed. Seasonal work fills the rest of the calendar: spring clean-outs, algae control in summer heat, leaf netting in autumn and the occasional fish rescue after a pump quits.
Some pond firms also sell fish, plants and supplies from a shop, which would fit the fish-store listing attached to the H Street address.
Planning a pond project
Ask for a written scope that names the liner type and thickness, the pump size and its running cost, and the filter design, since those choices decide how clear the water stays. Larger excavation, electrical and plumbing work in California can call for a contractor's licence, so ask for the CSLB number and look it up at cslb.ca.gov. Ask how long the build will take, who installs the outdoor outlet for the pump, and what a maintenance visit covers. If you keep koi, ask how the fish will be held during a clean-out.
Around the valley
From Napa the natural service area runs north up Highway 29 through Yountville, Oakville and Rutherford to Saint Helena and Calistoga, climbs to Angwin on Howell Mountain, and reaches south to American Canyon. That covers most of Napa County, from the valley floor to the hillside estates.
Call 707-251-3781, the number shared by the chamber's record and the current listings. If you are Jesus Avila, claim this listing through the chamber so the address, the name and the services can be brought up to date.

Preguntas frecuentes
Típico de este tipo de negocioHow often does a garden pond need cleaning?
Most ponds benefit from a full clean-out once a year, usually in spring, plus regular filter care and skimming. Heavy leaf fall, a large fish load or an undersized filter can mean more frequent visits.
Does building a pond need a contractor with a state licence?
It depends on the size and the work involved. Excavation, electrical and plumbing beyond a small job generally require a state contractor's licence in California. Ask for the CSLB number and check it before signing.
Why does my pond keep turning green?
Usually too much sunlight and nutrients for the filtration to handle. Shade plants, a correctly sized biological filter, an ultraviolet clarifier and fewer fish or less feeding are the usual fixes a pond specialist will look at.
What happens to my fish during a clean-out?
They are normally netted into a holding tank filled with pond water, kept aerated and returned once the pond is refilled and dechlorinated. Ask how the crew handles this before the visit.
