The work that I had done by Poseidon Waterproofing was to have their system installed into my basement because I had constant problems with my basement flooding. I would, and have recommended Poseidon to anyone. They do top notch work, are punctual, and all of their staff are courteous, helpful, and extremely efficient in all that they do. I could not be more pleased than I am with Poseidon. It is truly wonderful to have a dry basement!
