Derick and his crew from Lake Force Defense lived up to all my expectations. I was reluctant at first that they could take care of my pesky lily pads at my Lake Stevens home.

They went above and beyond make sure my waterways were clear of aquatic invasive species. I wish our Washington State Departments of Ecology, Natural Resources, and…

Hi CJ, We thank you and your community for using us for your milfoil removal needs. Your community deserves an invasive species free, beach escape and we thank you for choosing us to get you there.

Derick and his crew from Lake Force Defense lived up to all my expectations. I was reluctant at first that they could take care of my pesky lily pads at my Lake Stevens home. The work they did looks great. They were professional and respectful of my property. When I had a few lily pads come back in an area that they did not cover, the crew came back and treated the area free of charge. I would definitely recommend Lake Force Defense to treat those obtrusive weeds at your water front property.

Hi Brent, Thank you for your kind review. We understand our solution is new and can take some education to understand why we think it is best. We thank you for taking a chance and using us for your waterfront restoration needs. If you ever need anything else please do not hesitate to reach out! Best, Joe M.

It was an absolute blast dealing with Joe and his team. They have the knowledge and expertise to do an incredible job, and a great enthusiasm for it. They went above and beyond make sure my waterways were clear of aquatic invasive species. I wish our Washington State Departments of Ecology, Natural Resources, and Fish & Wildlife cared as much about our water/waterways like Lake Defense Force does.

Hi David, Thank you for your kind review. The project you had for us had its unique challenges but this made the job even more exciting. We cannot wait to see how your stream is going to be doing this upcoming year! Best, Joe M.

Lake Defense Force proved to be the best hire we could have made for our dredging project. Their team came out to our golf course to hand dredge around our irrigation intake and exceeded expectations. We appreciated their efficiency, professionalism and ability to cater to our unique situation. We are looking forward to continuing to work with Lake Defense Force in the future.

Hi Justin -- I appreciate your kind words. This was such a fun and unique project and we thank you for the opportunity. Just keep the curve balls coming! Kind Regards, Joe M.
