Reclaim your shoreline, one clean cut at a time.
Doc Seaweed is a certified scuba diver who gets in the water and hand-cuts seaweed at the root — at private piers and swim areas around Lake Geneva. No chemicals, no shortcuts. Want a permanent fix? We also supply and install LakeMat and MuckMat barriers.
Meet Doc Seaweed
Doc Seaweed started as a summer money problem. One of my best friends and I were both 18 and certified scuba divers with plenty of free time and not much money, trying to figure out how to turn diving into dollars.
His dad — an actual doctor — looked at all the weed-choked piers around Lake Geneva and had a simple diagnosis: nobody wants to swim in that, and nobody local was offering to fix it. So the two of us suited up, got underwater, and started hand-cutting weeds at the root instead of just skimming what showed above the surface. The name Doc Seaweed stuck ever since.
That first summer job turned into a real business. My friend's since moved to Florida — he still comes back up to help out now and then — but the underwater, hands-on approach never changed. About five years ago, I started supplying and installing LakeMat and MuckMat barriers too, for customers who wanted their swim area weed-free for good, not just for the season.
We serve Lake Geneva, Wisconsin exclusively — because staying local means every pier gets treated like it's the only one on the schedule that day.
"Every pier's different. I treat yours like it's my own." — Doc Seaweed
Hands-on, underwater seaweed removal
A clear, swimmable shoreline without chemicals or heavy equipment — just careful, manual work at your pier.
Doc walks your shoreline, checks growth and bottom conditions, and quotes a flat price before any work begins.
Doc suits up in full scuba gear, works underwater at the root, and physically removes weeds from your swim area — not shredded and left to wash up elsewhere.
Book return visits to keep your swim area clear from Memorial Day through the last swim of summer.
LakeMat & MuckMat installation
Cutting keeps your swim area clear all season — but if you want weeds gone for good, Doc Seaweed supplies and installs both 12' x 24' XL mats from LakeMat.
