We specialize in wood rot repair. Choose your area of interest below for a solution to your rot and wood preservation problems. Or go directly to our product line overview and ordering form.

For over twenty years, we have helped customers fix or prevent their wood rot issues. While we sell a variety of products, wood rot repair has been done, primarily, with three products: CPES, Fill-It, and Layup and Laminating Epoxy Resin. For decades, these products have proved excellent in this role. However, supply issues have necessitated that we find other products for our customers to use for their rot repair needs. We are happy to offer products that, used correctly, will perform exceptionally well in the rot repair market. We stand ready to help customers with their repair needs, using these new products. We have the products, and equally important, the experience to help you make a strong, permanent repair. Please contact us for more information.

Have questions?

Contact us by phone 206-364-2155 or e-mail (send us your pictures) at and we will gladly answer questions about our products or how to apply them. With 20+ years of experience and many more in the boating and construction industries, not much surprises us. We are here to help our customers solve their issues. Let us help you to not have any surprises in your repair project.

Wooden Boats

Wooden Boats

Repairing and maintaining wooden boats involves many variables and procedures. We cover the different types of construction and offer some advice on how to make repairs.

Fiberglass Boats

Fiberglass Boats

There’s wood under that glass shell... and we all know what that means. Glass boats are completely different so we’ve dedicated a whole section to these special rot repairs.



Wood rot treatment, prevention, and application techniques for old houses, new houses, attic to basement, indoor and outdoor. Diagrams and photos accompany sound advice on some common problem areas.

Log Homes

Log Homes

Log homes have their own peculiar set of rot problems... usually serious because of log structural importance and because logs are not easily replaced. In this section, you'll find step-by-step, illustrated instructions for restoration of rotten logs, plus an invaluable section on rot prevention.

Product Testing

Product Testing

Ours vs. Theirs -- We test CPES™ against other epoxy-based products advertised to repair wood rot. The results surprised even us!

Our ‘Zine is articles on all types of tid-bits about restoring rotten wood, information on wood in general and anything we think might be interesting to share. We also are including a list of “What’s New?” from around our entire site. So you’ll want to check back on this link often.

We encourage you to submit items, large or small, that you think would be interesting. Our process is simple enough: We take what you submit, edit it if necessary, and then upon request submit a proof for you to review. With your approval, we post.
