This is my first review, so bear with me. I tend to write longer than I ought to. Perma-dry was recommended to me by a friend. They came all the way out to Enumclaw for the work. Scope of work and estimate was done by Aaron Calvo, who had more training and experience than I would expect from the boss' son. Very competent, explained everything, gave me several options, made some suggestions, and didn't try to pressure me into going high-end. I checked pumps with other outfits, found Perma-Dry was selling the best, put in a two-pump system to dry out my crawlspace and keep it dry even when power goes out (happens often in windy Enumclaw). The crew he sent worked super hard all day, digging a great perimeter drain all around the inside of the footings, hauling out yards of dirt and rock thru the tiny access hatch, replaced the ground-cover with much heavier plastic, put in a big collector basin, installed the main pump and the battery-backup pump, ran a 1.5 inch outlet pipe to a corner, drilled thru the footing and fed the outlet pipe into a roof-drainline, tested the system thoroughly, tied up some loose insulation, and left the crawlspace and the floors spotless. All for $5,000. Wow!
Pros: Fast, reliable, good work. They ain't cheap, but they are worh the money.
Cons: Can't fault them...but I wish they'd found the plugged drain the first time around.
