Frequently Asked

Answers before
you call.

01

How often does a koi pond need cleaning?

A full drain-and-clean once a year (spring) is plenty for a well-filtered pond. Add spring open + fall close visits for a hands-off season.

02

Do you service ponds you didn't install?

Yes — we service any pond in our Suffolk County coverage area, regardless of the original builder.
