What a cleanout is for

From pea soup to see-the-bottom clear

Sludge, sunken leaves and algae build up in every pond. A proper cleanout removes the muck, rinses the rock, checks the pump and filter, and gets the fish settled back in.

The St. Louis pond year

What your pond needs, season by season

Timing shifts with the weather each year, but this is the usual rhythm for backyard ponds around St. Louis.

Mar – May

Spring opening

Clear winter debris, restart the pump and filter, and add bacteria before algae season.

More
Jun – Aug

Summer upkeep

Skimmers, string algae, top-offs and pump checks. Good time for a maintenance plan.

More
Sep – Nov
Now

Fall closing

Net before the leaves drop, clean out what sank, and get the winter plan set.

More
Dec – Feb

Winter watch

Keep a hole in the ice for fish, and call about leaks or a de-icer that quit.

Questions

Quick answers

Is STL Pond Cleaning a pond company?

No. STL Pond Cleaning is a referral service operated by Thurr Solutions. When you call or send a request, we connect you with an independent local pond professional who does the work and sets the price.

Does it cost anything to request help?

No. Calling or sending a request is free, and you're under no obligation to hire anyone. Any price for the work comes from the pond pro, and you decide whether to go ahead.

What areas do you cover?

The St. Louis metro: St. Louis County, St. Charles County (including O'Fallon and St. Charles), Chesterfield, Kirkwood, Webster Groves, Ballwin, Wildwood, Florissant and the Illinois Metro East. If you're nearby but not listed, call anyway.

When is the best time for a pond cleanout?

Spring (around March to May) and fall (around October to November) are the most common times, because the fish are less active and you're either clearing out winter debris or getting ahead of leaf drop. Problems like a leak or a pump failure shouldn't wait for a season.
