These are some of the most common questions to pop up from our customers. Don’t see your question answered? Contact Us

Is the estimate really free?

Yes! The estimate is free, and if it is determined that the client would be best served by a design, then the designer will provide a proposal.

Can we have a consultation so we can do the work ourselves?

Yes, we will offer design expertise for a fee.

How does the design process work?

We use a 5-step process to ensure the same quality of work across projects.

How long will my project take?

Landscape project lengths vary. It can take 1-2 days up to months depending on the complexity and size of the project.

How long do I have to wait for my installation to start?

Installation times from the point of the contract vary on the season. They can go from 3-4 weeks in the winter and summer months to 4-8 weeks in spring and fall, which are the busier seasons. Additional wait times could be caused by the availability of plants, the permitting process, and engineering if necessary.

How much should I water after installation?

We have a one-year warranty on all our plants and trees. The warranty does require watering, and we will provide watering instructions at the end of your project.

What is the process if a plant or tree dies?

If a plant or tree dies within one year, reach out to us. We can do an on-site review. Please send pictures and the name of the plant when you contact us. For all warranties, it’s a one-time replacement warranty. We encourage clients to plant those warranty replacements in the spring or fall, which are the optimal planting times.

Do you warrant transplanting?

Transplanting any tree or plant is a risky procedure. You should not expect 100% of your plants to survive.

How often will we see our maintenance team?

Our maintenance contracts are weekly, bi-weekly, or monthly from April to October. We come out in March for prep work, and in fall and winter for leaf cleanup. All contracts can be customized to the client’s needs.

Do you warrant drainage?

Every landscape job has some element of water management, from the smallest to the largest. We’ve been in business since 1960, and we’re experts in drainage. While we always give our best efforts and advice, we can’t 100 percent predict water direction or volume. For those reasons, we don’t warrant our drainage jobs.

Do you do emergency drainage work?

It depends on availability. Call to inquire.

Can I do my project in phases?

Many clients decide to do their projects in phases. We may hardscape in spring and plant in fall. Our landscape designers can work with you to determine the appropriate phases and steps.

What if I decide to make changes in the middle of a project?

We’re happy to work with clients. Things can come up in the course of the project that lead to clients wanting to make changes. We can work with you to make changes that are deemed appropriate within the scope of the project. Any changes can result in a higher cost for the project.

How far in advance should I make my decision with regard to the color of my pavers?

With most contracts, we encourage clients to make color decisions by the signing of the contract or very soon after so that we can ensure that the product is available.

What kind of guidelines does Johnson’s follow for its hardscape installations?

Johnson’s follows all industry-standard requirements when building its hardscapes, including stone walls, stone patios, pavers, etc. In the event that, work requires engineering, Johnson’s will perform the protocols indicated by the engineers and codes required by inspectors.

What if my project needs permitting or engineering?

Increasingly, projects in the DMV require permitting and engineering, particularly if they involve walls at a certain height and sediment control. All permitting and engineering is the responsibility of the client. Johnson’s does offer permitting and engineering assistance for a fee because it is so challenging for homeowners. We work with specific permitting companies and engineers to get your project done.

If you get another contractor who says your walls or sediment control won’t involve permitting, it’s a red flag.

Can I buy my own materials?

Sure. Johnson’s will work with you if you decide to purchase your materials separately. Clients who do so won’t get the warranty protections for the plants or hardscapes they purchased.

Do you demolish and haul away the existing project?

Yes, that will be included in the plan and budget.

Do you work with subcontractors?

Johnson’s has a number of experienced and veteran crews that include masons, planting crews, lighting crews, carpenters, and other skilled workers. From time to time, we do use subcontractors to offer more expertise to clients and to decrease the wait time for our clients.

Does the crew do clean up after a project?

After every project, our crew will clean up and as much as necessary will attempt to restore areas disturbed in the course of the project, to include overseeding and oversodding if necessary.

Do you install high voltage landscape lighting?

All our landscape lighting is low voltage and requires a dedicated outlet for our transformer. Clients who need to install a dedicated outlet will need to hire an electrician.

We answer phones Monday-Friday 8-5. If you have questions, please call (301) 656-6414.
