Keystone Contracting Inc UBI: 601032411 417 NW 209TH ST RIDGEFIELD, WA 98642

Keystone Contracting Inc UBI: 601032411 417 NW 209TH ST RIDGEFIELD, WA 98642 is licensed as an asbestos abatement contractor in Washington, which authorises it to remove, encapsulate, or repair asbestos-containing materials — work that unlicensed contractors cannot legally perform. Licensed abatement follows a strict process: the work area is sealed with plastic sheeting and placed under negative air pressure with HEPA-filtered units, workers wear respiratory protection and disposable coveralls, and all waste is double-bagged, labelled, and manifested to an approved disposal facility.

Before hiring, confirm the scope in writing: what materials are being removed, how the area will be contained, where the waste is going, and whether final clearance air testing is included. If the testing is done by an independent licensed consultant rather than the removal firm itself, even better — nobody should grade their own work.
