Denison Landscaping Plans and Services

Unlike traditional lawn care and weed control companies, Denison Landscaping focuses on the design of your outdoor living space. The company offers full-service design services and builds projects for landscapes, hardscapes, irrigation systemsoutdoor lighting, and repair work.

Landscaping Services

Denison Landscaping advertises full-service landscape design services for those looking to re-envision their outdoor living space. Within their landscape division, specialists help customers see the big picture, which could look like balancing out soft elements such as gardens and lush lawns with hardscape features like porches and patios.

Denison ensures that the collaboration process is personalized to each project, allowing an open door of communication throughout the design stages.

Landscape designs have included grading, planting, seeding, sod installation, drainage, reforestation, and seasonal enhancements.

Included in its landscaping services are ample commercial landscape architecture offers, as well as warranty and repair work both with Denison or building partners.

Pro Tip

  • Jenn, This Old House landscape designer, advises homeowners to start by identifying their personal style before diving into a design: “What I tell homeowners is first figure out your style. They could go online, start a binder, start a folder, Pinterest, start a board, or take pictures of things when you do a drive-by somewhere.” Collecting 20 or so images of landscapes you love can help a designer quickly understand your vision—an approach that pairs well with the personalized collaboration Denison offers.

Hardscape Services

Though the landscape work goes hand-in-hand with hardscapes, the majority of Denison projects feature complex designs that have changed the structure of an outdoor area.

A few examples of hardscape projects that Denison Landscaping has tackled include outdoor kitchens, firepits, outdoor fireplaces, pavers, walkways, patios, fences, retaining walls, porches, stairways, poolscapes, outdoor dining areas, driveways, and lighting and outdoor sounds systems.

Irrigation Systems

Denison Landscaping offers the installation and management of both new and old irrigation systems. Specialists from the company can analyze your lawn’s irrigation needs and make recommendations to either alter or install a new system based on your budget.

Pro Tip

  • For homeowners looking to maximize water efficiency—and reduce long-term irrigation costs—consider asking about drip irrigation zones. On a recent This Old House project in Texas, landscape contractor Lee recommended adding a dedicated drip irrigation zone for container plantings, noting: “It’s a smart watering. We’ll put it—you know, it’s not spraying off. It’s not evaporating.” Drip systems use pressure regulators and filters to deliver water directly to plant roots, reducing waste and potentially lowering your water bill over time.

Denison Landscaping offers three irrigation contract plans that range from $250–$475 per year. Denison is also an EPA WaterSense partner for its attention to water sustainability and eco-friendly runoff regulations.

Pro Tip

  • Upgrading to a smart irrigation controller can significantly reduce water costs. As demonstrated on a This Old House project, a smart controller “collects historical weather data” and “adjusts the system seasonally,” while a wireless sensor detects local conditions in real time—delivering what the installer described as “huge water savings everywhere just to not waste.” Paired with a smartphone app, homeowners can also shut off the system remotely when it rains, adding another layer of cost control.

Denison Landscaping Locations

Though Denison is a popular landscape design company in the Mid-Atlantic region, it only services a few locations. The company is headquartered in Fort Washington, Maryland, and has satellite locations in the following cities:

  • Pittsburgh, Pennsylvania
  • Delmar, Delaware
  • Milton, Delaware

The company services a large part of the Mid-Atlantic region, including a perimeter around Delaware, Maryland, parts of Virginia, West Virginia, Washington, D.C., and southwestern Pennsylvania.


Denison Landscaping Reviews

Denison Landscaping isn’t accredited by the Better Business Bureau (BBB) and has a B- rating. Below are two reviews from the company’s Yelp page:

“[The architect] was an incredible project manager from start to finish. He was such a pleasure to work with! He was extremely responsive, thorough, and patient despite my constant questions. The epitome of great customer service!” —Felicia B. via Yelp

“[Our project coordinator] said that if I ever have problems, I can always call them and they’ll come out. They do so but begrudgingly. They will hem and haw.” —W.W. via Yelp


Denison Landscaping vs. Competitors

Although Denison Landscaping offers extensive landscaping services and has a responsive customer service team, it doesn’t offer general lawn care services, isn’t available in a majority of states, and doesn’t offer additional benefits like pest control. We recommend TruGreen and Weed Man if you’re looking for those solutions.

Our Conclusion

If you’re on the hunt for a company to take care of pest and weed issues, you may need a more general lawn care company to take on these challenges.

We recommend TruGreen as your go-to experts on year-round lawn care. It’s an ideal pick if you want to elevate or heal your current lawn and landscape, as well as seek advice about regional plants that will improve your home’s curb appeal. The company has locations across the U.S. but provides a personalized experience for all customers.


FAQs About Denison Landscaping

When is the best time of the year to call for a Denison estimate?

It’s recommended that you call in the winter, as Denison Landscaping’s residential design and build department works a tight schedule during most of the warmer months. Calling and meeting in the winter can help secure a time within the next year for a project to take place.

Is there a minimum job cost requirement?

Yes, but it depends on where you live. For example, if you live outside the Fort Washington area, there’s a $500 job cost minimum.

Do I need a permit for landscape design work?

You may need a permit depending on your location. For example, areas within Prince George, Fairfax, and Howard counties in the Washington, D.C. area have strict permitting laws and regulations.
