You Don't Have to Live in a Swamp

Our area has relatively high rainfall - especially in the summer which often means gardens turns into a soggy mess.

  • Puddles stick around for days, making parts of the garden unusable.
  • Plants struggle or rot in waterlogged soil.
  • Paths become muddy or slippery after rain.
  • Standing water attracts mosquitoes and other pests.
  • Damp conditions slowly damage fences, sheds, and even foundations.

That's where we come in...

We've Done a Lot of Landscaping in the DC Metro Area Over the Last 25 Years

Tenleytown Lawn & Landscape team

It's a team effort, but the buck stops with Lisa.

Lisa took over the business after the passing of her husband, Peter Galvin.

For 25 years prior, Lisa practiced emergency medicine, where she honed skills that have surprisingly transferred beautifully to running this exceptional business that Peter built. In emergency medicine, she learned the importance of building trust with people, often in high-pressure situations. This same focus on rapport and clear communication is something she brings to every interaction with her clients.

A Garden You’ll Want to Spend Time In

There’s no single way to fix drainage problems, but there are a few reliable options. The best approach depends on your garden, the type of soil, and where the water goes after it rains. Here are some ways we've used in this area:

Rain gardens These are shallow areas with plants that collect rainwater from roofs or paths. The water soaks into the ground instead of running off. They help reduce flooding and also support birds, bees, and other wildlife.

French drains This is a simple underground system made of gravel and pipe. It moves water away from spots where it builds up. Once it’s in place, it usually blends in and doesn’t change the look of your garden much.

Grading This means shaping the ground so water flows the right way, usually away from your house. It can also help make parts of your garden flatter and easier to use.

Custom Design Plans

We offer personalized design plans that reflect your unique taste and needs. Our 2D and 3D renderings help you visualize the transformation, ensuring that every detail is perfect.

Stress-Free Installation

We're licensed, bonded and insured. We use our own employees, most of whom have been with us for years. We'll arrive on time, work efficiently and clean up after we leave. We'll give you your project manager’s and the owner's phone numbers in case you have any concerns or questions.

Love Your Home and Garden

Once the work’s finished, you get a space that feels good and doesn’t ask much of you. It’s tidy, well-built, and easy to look after so you can spend more time enjoying it than maintaining it. And, if you like, we'll maintain it for you.

A Team Who Shows Up, Does It Right, and Makes Your Place Look How You Imagined

Our process is designed to make your landscaping project smooth and enjoyable, from start to finish.

1

Start With a Complimentary On-Site Consultation

If your project is simple, we'll prepare a fixed-price quote. It normally takes us about a day to get back to you with your quote.

If you're planning a bigger project our landscape designer will work with you to turn your vision into 2D or 3D renderings. This will help you be certain that you're going to get exactly what you had in mind. After that, we'll prepare a quote. If the budget is tight we'll work with you to come up with a more affordable phased approach.

2

We Get to Work

Once you're comfortable with your quote we'll schedule your project. We'll do our best to accommodate any deadlines you might have.

We turn up when we say we will, keep you in the loop, and make sure the place is tidy before we leave. The team is made up of skilled, full-time staff—people we know and trust. They work carefully and take pride in doing a job properly.

A Space That Feels Good to Be In

At the end of the project, you’ll have an outdoor space that looks how you pictured—and works the way it should. The groundwork is solid, the plants are healthy, and the details are done right. It’ll feel finished, cared for, and ready to enjoy.
