Monthly Service Plans, Explained
Some owners want one solid cleanout a year. Others want the pond off their list entirely. Our Premium plan runs roughly $460 to $609 per month by pond size, and VIP Stress Free runs roughly $710 to $859 per month with a visit every two weeks.
On a service visit the crew empties the skimmer, rinses filter media, trims and thins plants, checks the pump, plumbing, and water level, and looks over the waterfall for leaks or settling. Small problems get flagged early, while they are still cheap to fix.
Why Nashua Ponds Take a Beating
Nashua sits along the Merrimack River, where soils are often sandy glacial outwash and granite ledge is common nearby. Winters run colder and longer than in central Massachusetts, and deep frost heaves stone edges and can stress liner seams.
By spring, a pond has spent months collecting leaves under ice. That material rots into muck and feeds algae once the water warms. Because our crew comes up from Cherry Valley, we group Nashua with other New Hampshire stops in blocks, which keeps the schedule tight during the short spring window.
Spring Cleanout Pricing
A small pond cleanout runs roughly $1,300 to $2,500. An average cleanout runs roughly $2,500 to $5,000, and advanced cleanouts run $5,000 and up.
Pricing by size and service level: up to 90 square feet, about $2,264 to $5,409; up to 180 square feet, about $2,437 to $6,075; up to 340 square feet, about $2,767 to $6,544, depending on whether you choose Standard, Premium, or VIP. Heavy muck, large fish populations, and tight access raise the number. Fall netting and winter prep are priced separately.
Inside a Nashua Cleanout Visit
We net your fish into a holding tank filled with their own pond water. The pond is drained, and muck and debris come out. Rocks and gravel are power washed without sterilizing them, so the beneficial bacteria stay in place.
Next, filters get cleaned, the pump and plumbing are inspected, and overgrown plants are divided and repotted. We refill with dechlorinated water, match temperatures, and return the fish. Cold water bacteria go in while temperatures are still low, and feeding waits until the water holds at 55°F.

Frequently asked questions
How often does a Nashua pond need a full cleanout?
Most ecosystem ponds need one full cleanout each spring. Ponds under heavy tree cover, ponds with many fish, or ponds without a skimmer may need more attention. A monthly plan reduces how much muck builds up, which keeps each spring cleanout lighter.
What is the difference between Premium and VIP Stress Free?
Premium covers regular monthly care and runs roughly $460 to $609 per month by pond size. VIP Stress Free runs roughly $710 to $859 per month and brings the crew out every two weeks, so issues get caught faster and the pond stays at its best through summer.
When can I start feeding my fish again in spring?
Wait until the water temperature holds steady at 55°F. Below that, fish cannot digest food well, and uneaten food fouls the water. In southern New Hampshire that can take longer than people expect, so a pond thermometer is worth having.
Can you fix problems you find during a cleanout?
Often, yes. Small items like a worn pump part or a loose fitting can be handled during the visit. Bigger issues, such as a liner puncture or a leaking waterfall box, get documented and quoted separately as a repair so you can decide how to proceed.
