TimberSeal Logo - no shadow

Started in 1996 with our home office in Valparaiso, Indiana, TIMBERSEAL INC was born to fill a market need so often forgotten in the exterior wood care industry.   Our business was found on the principals of quality, pride and trust.  We have been servicing the great lakes region for over 29 years now providing exceptional service, an amazing product all at a fair and reasonable price to our clients.  It is our goal to leave every customer with a desire to do future business with us and with the hope that by providing this exceptional service you’ll tell all of your friends and neighbors about us! 

TIMBERSEAL INC SPECIALIZES in the restoration and refinishing of exterior decks, docks, fencing, cedar siding, log homes and other exterior wood structures.  Our pride and joy is in the smile on your face when you see the dramatic and gratifying results that our proprietary restoration process provides on every job.  Through specialized training, proprietary products and some of the best finishes available on the market, we can turn that dingy old gray deck, fence or siding into something beautiful again.

Greg Rentschler
Founder, CEO and world traveler?

Greg, a long time Valparaiso resident, started TimberSeal Inc in 1996 after being involved in motorcyle racing growing up. That may seem like a bit of a reach to understand, but pressure washing was something Greg was pretty used to doing. After every race his bike needed cleaned and keeping his bike and other toys clean was something he took pride in. His love for pressure washing grew and led to power washing jobs in the afternoon and weekends washing houses, decks and concrete driveways. In turn this grew and turned into TimberSeal Inc in 1996. In his off time, Gregs loves are his significant other Cortney, their combined five kiddos and traveling the world to seeking new and exciting adventures! He still has a love for motorcycles too and one of his favorite trips was to Sturgis on his Harley in 2022.

Our Crews

Our crews are the foundation of TimberSeal! Without their hard work, attention to detail and exceptional customer service on the job site, we would be where we are today. Our crews in total have stripped, restored, sealed and maintained well over 10 Million sq foot of decking, railing, fencing, cedar siding and other wood structures. 10 MILLION! Thats like sealing the entire Amazon rain forest! Ok… maybe not that big but you get the picture. Bottom line is, without exceptional crews there’s no exceptional service and without exceptional service theres no exceptional customers. Without exceptional customers there’s no TimberSeal! With that we say thank you to all of our staff, crews and clients as we appreciate you a great deal! You have made us what we are today!

“Greg and his team did an awesome job. We had a number of cedar boards replaced on our house in addition to a complete paint job using Sherwin Williams paints. Greg stands behind his work in the event there may be an issue. That says alot about the integrity and commitment from Greg Renschler Timberseal’s owner. I have referred Timberseal to a number of residents in our Shorewood Subdivision including our HOA and everyone was pleased with the quality and workmanship that Timberseal offers..”

“Highly recommended! From the office staff to the wash and stain crews. Our deck came out beautiful. Very impressed with the way it turned out. Crews did a great job! Was done prior to putting the cover on the pool and not one drop of stain anywhere but on the wood. Timber seal will be our “GO-TO” from this day forward for any wash and stain project.”
