TimberSeal

Greg Rentschler first got into pressure washing while cleaning motocross bikes after races. What began as part of a personal hobby gradually turned into weekend and afternoon power washing jobs, before eventually leading him toward the wood restoration and sealing work that became TimberSeal. As the work grew, Greg began noticing how many homeowners needed help restoring and maintaining exterior wood surfaces. That early experience eventually grew into a business focused on the care of decks, fences, cedar siding, docks, and other exterior wood structures.

What Greg still enjoys most is seeing what careful restoration can bring back to older wood surfaces. He sees old decks as something that can often be restored rather than replaced or covered up. Beneath years of weathering and worn finish, there may still be wood worth bringing back to life. Customers are often surprised by how dramatically a deck can change through proper cleaning, sanding, and refinishing, especially when the goal is long-term preservation instead of a short-term fix.

That long-term mindset still shapes the way the business operates today. Greg believes maintenance matters most before a deck reaches the point of heavy deterioration, which is why staying connected with customers has become such an important part of the experience. People appreciate having someone who keeps track of the upkeep and reaches out when it may be time to take another look. Over the years, TimberSeal also developed its own finishing system focused on long-term maintenance rather than repeated stripping and refinishing. There is a practical steadiness to that approach that fits naturally with the kind of work TimberSeal does.

Over the years, the business has grown steadily, but Greg still speaks about it in personal terms. He enjoys meeting homeowners, talking through projects, and helping people understand what their wood surfaces actually need. That focus on relationships carries through the rest of the business as well, including the close-knit culture Greg has built with his team over the years. Customers often point to crews that work carefully, clear communication throughout the process, and attention to detail that helps homeowners feel comfortable trusting someone with their property. Whether it is protecting landscaping during a staining project or taking time to explain stain options, there is a noticeable respect for the home and the person who lives there.

Greg is also looking ahead to the future of the business with the same steady approach that helped build it over the years. While TimberSeal remains rooted in its relationships and reputation, Greg continues to explore ways to grow beyond Northwest Indiana without losing the personal approach that shaped the business from the beginning.

For many homeowners, outdoor spaces become part of everyday life, whether that means quiet mornings on the deck, evenings around a fire pit, or simply enjoying a yard that feels finished and cared for. TimberSeal approaches those spaces with the understanding that maintaining them properly is not just about appearance. It is about helping them continue to be used and appreciated for years to come.
