jThe property you worked on is in Astoria, OR

the basement waterproofing is not what we thought it was. we are not sure the encapsulation material will take care of the mold or keep bugs from entering through the crack in foundation, but we will give it a try. The encaptulation ovr the dirt floor & cement foundatin seems to be doing its job. The odor and dampness seems to be deminished.

We believe that part will be great. We may have been wrong about the actual basement walls however, and that we may have to remove and paint with a cement sealer.
