Since 1977 Thunderbolt Wood Treating has been a leader for wood treating services in California. Thunderbolt was founded by three partners but since January 1, 2002, Leonard and Grace Lovalvo have retained full ownership and have created a family business creating jobs for over 40 local residents.

Thunderbolt Wood Treating originally started with just one retort primarily focusing on producing agricultural products with the CCA preservative and Borates for residential use. The Ag industry has always been a very important part of our business and over the years we have progressed to adapt to an ever changing market. Here in California we are very mindful of our fragile ecology and from the beginning we instituted our treating plant as a Zero-Discharge facility.  We take great pride in being a Green facility and our current treating methods are an example of our commitment to protecting the planet. Our treating services are EPA approved and meet AWPA (American Wood Protection Association) standards for treating methods.

Our treating facility is able to fulfill many different requirements.  With the variety of preservatives available, along with additional services we offer such as; milling for special and unique projects.  Currently we are able to treat wood products for use in commercial, aquatic and marine, agricultural, residential and industrial applications.  We manufacture guardrail, utility poles and a limited amount of custom milling and fabrication.  Other services include: Color Staining, Kiln Drying for Heat Treating, KD, KDAT (Kiln Dry After Treating), and pole conditioning.  Our latest addition to the list of services which we provide is a protective barrier system, known as SG E-375-08, a marine grade Polyurea barrier system.

Over the years we have grown to better serve our customers as by expanding our capacity.  In 1980, we added two retorts and our first Kiln.  In 1989, we installed three more retorts; which brought our treating capacity to six retort cylinders.
