Fontana Wholesale Lumber, Inc. is mainly a TSO (Treating Service Only) facility.  What is treating service only? You bring in your stock: lumber, timbers, plywood, and we will treat it to the appropriate specifications.  We offer a variety of treating services such as D-Blaze Interior Fire Retardant for those special multi family, multi story specified jobs that require an Interior Fire Retardant, ACQ treatment for outside/ground contact projects, and Borate treating for bottom plate.  Please call for pricing and time allowances.

We also provide Heat Treat Service for those customers supplying the crating and pallet industry where overseas use requires an International Standard of Phytosanitary Management (ISPM 15) “HT” Stamp.

Fontana Wholesale Lumber, Inc. stocks some treated products available for purchase, such as landscape timbers, mobile home pads, and round stock (posts and poles).  Round stock is available both treated and untreated, with sizes ranging from 4” – 16” in diameter, and lengths up to 50’ in stock.

  • All round stock is stored outside and subject to natural checking and splitting.
  • All round stock orders are final once confirmed. Please be advised that orders are pulled and cut to your specifications and no returns or exchanges will be granted.

* Fontana Wholesale Lumber does not sell to the public.  If you are a homeowner or contractor looking for treated lumber, please call your nearest lumber yard and ask for your treated lumber needs.
