Window Wood Rot Repair
I had a fantastic experience with Preservan. Our tech, Josie, was a careful, professional, and incredibly kind. She is clearly an expert and went the extra mile to take the necessary steps to protect my old wood windows.
It is a great value to be able to repair rather than replace, and it’s clear this team really knows their stuff. If you want the job done right, call them.

Repairs at a Fraction of the Cost of Replacement
Preserve did an amazing job repairing our wood window. Our window had a small amount of rot, everyone we called wanted to replace it, they said it would cost $4,000 and take months to get. Preserve fixed it in two days for a fraction of the replacement cost. Their epoxy tech Ty was amazing and so professional! With their help we may never have to replace our windows!

Fast, Reliable, Wood Porch Post Repairs
I had two 8×8 cedar posts holding up my back porch roof that were rotting at the bottom. Ben came over and advised me they were good candidates for repair. The cost was less than half the quote I had received for replacement. We were on holiday when the technician did the work, but it was done exactly as Ben had described and was very neat and tidy. We could not have asked for a more satisfying experience.

Preservans Exclusive Epoxy Repair Technology
When wood rot repair is required, Preservan uses structural epoxy by Everesin — not wood filler — to create
permanent, shrink-free repairs that resist rot, moisture, and failure. Once cured, the repair restores strength and
stability that temporary compounds simply can’t match.
Frequently Asked Questions
What makes Preservan different from traditional wood replacement contractors?
Preservan specializes in permanent wood repair, not replacement. Instead of tearing out windows, doors, or structural wood, we restore and reinforce existing materials using advanced preservation techniques. This approach saves homeowners money, reduces waste, and preserves original craftsmanship.
Is epoxy wood repair permanent?
Yes. Preservan uses a structural epoxy system, not wood filler. When properly applied, epoxy chemically bonds to existing
wood, restores strength, and resists moisture and rot. Our repairs are designed to last and are backed by a 10-year warranty under the Preservan Promise.
Is Preservan a national company or a local service provider?
Preservan is a national brand with locally owned franchises. Each location is operated by professionals who live and work in the communities they serve, combining national expertise and standards with local care and accountability.
How long does Preservan’s repair or staining process take?
Many wood repair projects are completed in one to three days, depending on scope. Fence and deck staining projects are
often completed even faster. Timelines vary by project, but Preservan focuses on efficient, non-invasive solutions that
minimize disruption.
Do you treat termites or provide pest control services?
No. Preservan does not provide termite treatment or pest control. We specialize in repairing wood damage caused by rot, moisture, or past termite activity after the infestation has been addressed by a licensed pest professional.
