From Lawn Care to Life-Changing Property Work

Tanner Treacy was 12 years old when he started mowing lawns. No business plan. No fancy equipment. Just a young person who saw a need and showed up with the right attitude. Word of mouth carried that early work forward for years, and by 2012, TMT became official—first as a DBA, then an LLC in 2018.

But something shifted in 2023. Tanner realized his true passion wasn't in maintaining what existed—it was in transforming it. Septic installations. Site preparation. Drainage solutions that actually work. Retaining walls and seawalls that hold. The kind of work that solves complex problems and opens up new possibilities for families and businesses in Cortland. That's when TMT Excavation & Outdoor Services stepped fully into its calling.

Today, this isn't a one-person operation anymore. Tanner's mom runs the office. His dad oversees the shop. His wife supports the vision from behind the scenes. The whole team carries the same belief: your project matters because it's yours. That family foundation shapes everything we do.

What We've Learned Along the Way

We've learned that the people who choose us deserve better than a contractor who treats their job like a checkbox. Every septic installation, every site prep, every drainage project—it's an extension of someone's life and future. That's why we meet with you, listen to your vision, and work through the tough spots instead of around them. A complex slope? A drainage challenge? A space that feels impossible? Those are the moments that matter most.

We've learned that solutions don't come from rushing or cutting corners. They come from understanding what you're trying to accomplish, then finding the right approach—not the fastest one. That mindset, passed down from Tanner's early days of mowing lawns with care, still shows up in how we handle seawalls and retaining walls today.

We've also learned that trust is built in details. The way we communicate. The respect we show for your property. The pride we take in standing behind our work because we'd want the same if the roles were reversed. You're not hiring a transaction—you're working with a team that genuinely cares about the result.

How We Work

We start by showing up and listening. You tell us what you need—whether it's a septic system that will serve your home for decades, a landscape transformed with new drainage, or outdoor living spaces that become the heart of your property. Then we sit with the challenges, work through the options, and deliver something built to last.

If you're thinking about your property differently, or you've hit a problem that other contractors just shook their heads at, reach out. We'd like to meet you, understand what you're imagining, and show you what's possible when a team actually cares about the outcome.
