Wyatt and his Nemo team were phenomenal to work with, far exceeding my expectations on our challenging project in the San Juans. They made efficient work of replacing our ancient, deteriorating pier on an island with no ferry access, in winter, with significant tidal action - on time and on budget. Clear, honest communication, and extremely hard workers. I really cannot recommend them enough - would give 6 stars if I could!

Wyatt was able to address connection issues with our fenders and was timely and thorough. He’s a great communicator. We appreciated his work on our houseboat and will be return customers!!
