Pond cleaning and care in Town and Country, MO
Town and Country's large lots and estate landscaping mean bigger water features: koi ponds, long streams, formal fountains and, on some properties, earthen ponds that need a different kind of care.
In Town and Country, lined koi ponds and streams typically get a full cleanout every year or two plus spring opening and fall closing, while larger earthen ponds need aeration, shoreline and aquatic-plant care rather than draining. Call (314) 445-5517 to get matched with an independent local pond pro.
What's different about ponds in Town and Country
Lined pond vs. earthen pond
A lined koi pond or water garden gets drained, cleaned and refilled. A larger earthen or clay-bottom pond usually isn't drained; care focuses on aeration, aquatic weeds, the shoreline and muck. Tell us which you have so the right kind of pro calls.
Long streams and waterfalls
Long streams are where most 'leaks' hide: a settled rock, a low edge or a gap in the waterfall foam. The liner itself is often fine.
Landscape crews
Mowing, leaf blowing and fertilizing near the pond add clippings and nutrients. Ask the crew to blow away from the pond and keep fertilizer off the edges.
Timing
Town and Country sits between Lambert Airport and Spirit of St. Louis Airport, whose NWS average first fall freezes are about two weeks apart (November 2 vs. October 19). Low spots near creeks tend to frost earlier.
When to open and close a pond in Town and Country
The nearest National Weather Service climate station used for Town and Country timing is St. Louis Lambert International Airport. Its 1991–2020 averages put the last spring freeze (32°F) around April 2 and the first fall freeze around November 2. Treat these as averages: any given year can be weeks off, and water temperature (about 50°F) is the better trigger for opening, feeding and closing.

Maintenance plansIf you'd rather enjoy the pond than work on it, a recurring plan keeps up with skimmer baskets, filters and algae before small problems turn into a full cleanout.

Leak & pond repairMost "leaks" aren't holes in the liner.Town and Country pond questions
Can you help with a large earthen pond, not just a koi pond?
Sometimes. Earthen ponds and small lakes are a different specialty (aeration, weed control, dredging). Tell us the size and how it's used, and we'll try to match you with a pro who handles that kind of pond. If we can't, we'll say so.
How much does yearly maintenance cost for a large pond?
Cost rises with size. Angi lists about $1,500–$5,000 a year for ponds over 300 square feet, and HomeGuide about $1,000–$3,000 for extra-large backyard ponds. Your quote depends on the pond and the visit schedule.
Is it worth having a pro open and close the pond every year?
For big koi ponds, many owners think so, because the work involves heavy equipment, fish handling and winter prep for the pump and UV. Small water gardens are easier to do yourself.
Do you cover Town and Country, Frontenac and Des Peres?
Yes, along with nearby Creve Coeur, Ladue and Chesterfield.
