Milton Suqui of S & L Tree Service, and his colleague, Freddie, helped me remove a 60' tree, 18" diameter at the base, that had fallen into a tidal river adjacent to our property. The tree needed to come out immediately otherwise it would become a sieve catching winter blow down and other debris, and jeopardizing our little dock.
Get all the estimates you want from Thumbtack.com, but do yourself a favor and give Milton the first chance to do an onsite "final" estimate. Not only did Milton give me the best price, but he and Freddie came with equipment, ready to go the day of the on-site survey, and immediately got to work.
Remember, the tree was in the river, so there were some obstacles along the way, including submerged boulders which made the task more difficult, but our little team succeeded in accomplishing the goal. Using block and tackle, pulleys, ratchet straps, a pair of neoprene waders, and a couple of hearty chainsaws, the job was handled efficiently. All of the pieces of the stumps, and branches, and brush were piled neatly above the flood zone to create a new home for woodland creatures.
If they can remove a large tree from a moving, tidal river, imagine what they can do for you on dry land. Highly recommend.
