Treated Products Preservative Treatments H.M. Stauffer has been involved in the wood preservative business since 1975. Over the years while the preservative treatments have changed, one thing that hasn’t is our commitment to delivering a quality product to our customers. An extensive in-house QC program coupled with the use of SPIB as an independent third-party inspection service means you can expect a properly treated product delivered year round. We maintain a complete inventory of items including dimension lumber, timbers, boards, 5/4 decking, plywood, and deck specialty products ready for immediate shipment. Treating Service Only (TSO) is available for those customers preferring to supply their own lumber. We currently service independent retail yards and manufacturers in eleven states.
