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.
