Getting started

Do you charge for an estimate?

No. We come out, look at the property with you, and put a price in writing. The visit costs nothing and you are under no obligation afterwards.

How quickly do you answer?

Usually within one business day. If you reach voicemail we are out working on a property. Leave a message and we will call you back.

What are your hours?

Monday to Saturday, 8:00 in the morning to 5:30 in the evening. Snow and ice work happens whenever the weather decides, including outside those hours.

What areas do you cover?

We are based in Montgomery Village and work across Montgomery County, Maryland and the areas around it. Gaithersburg, Rockville, Germantown, Olney, Damascus and Clarksburg are all normal ground for us. If you are not sure whether you are in range, ask.

How do we get started?

Three ways, all reaching the same phone. Call (301) 978-6166, leave your number for a call back, or answer five quick questions so we know what we are coming to look at.

The work itself

What do you actually do?

Five things: lawn care and maintenance, retaining walls and stonework, fall clean ups, fences and gates, and snow and ice removal. The same crew does all of it, which is the point. You are not handing your property to a different company every season.

Do you install paver patios and walkways?

Yes. Paver patios, walkways, stone steps and seating walls are most of what you will see in the gallery, all of it work we did ourselves around the county.

Do you build retaining walls?

Yes, and they are the part of the job most worth getting right. A wall holds back wet ground, so the base and the drainage behind it decide whether it is still straight in ten years. See the permit questions below, because height changes what the county requires.

Do you do fertilization or weed treatments?

No. Those need a separate pesticide applicator certification and we do not offer them. We will happily work alongside whoever does yours.

Do you install chain link fencing?

No. Wood and composite, gates included. For chain link you want a fencing specialist.

Do you work through the winter?

Yes. Fall clean ups run to the end of the season, then snow and ice removal takes over, for homes and for commercial properties.

Do you take on commercial properties and HOAs?

Yes. Homes, commercial grounds, HOA and community property, and rentals for the people who manage them.

What happens to the debris?

We haul it away as part of the job. If you would rather keep some of it, say so before we start. Plenty of people want the stone kept for another project, or the wood left for a fire pit, and that is entirely your call.

Can I see work you have actually done?

Yes, and none of it is stock photography. The gallery is all real jobs on real properties around the county, including before and after pairs of the same spot.

Payment and guarantees

How do you take payment?

However suits you. Cash, check, card, and the usual payment apps are all fine.

Do you guarantee your work?

Yes. We stand behind what we build. If something fails because of the way we built it, we come back and put it right. Ask us on the day and we will tell you exactly what the guarantee covers on your particular job, since a patio and a fall clean up are not the same promise.

Are you insured?

Yes, on every job.

Permits and HOA rules

Do I need a permit for a retaining wall?

In Montgomery County, a residential retaining wall needs a building permit when the retained height is over 3 feet (36 inches), or when it supports a surcharge load, crosses a lot line, sits in problem soils, or forms part of a tiered wall system. A surcharge means weight sitting on the soil the wall holds back, such as sloping ground above it, a driveway, or a building footing nearby.

The county also caps a wall at 6 feet 6 inches measured from the lowest grade beside it, and anything designed over 7 feet has to meet the county's special inspection requirements. The current rules are on the county's own page for residential retaining wall permits.

Do I need a permit for a fence?

Yes, in most cases. Montgomery County requires a permit to install any type of fence. The exception is replacing an existing fence that was itself permitted, with the same kind of fence, in the same place, at the same height. Fences are capped at 6 feet 6 inches, and on a corner lot anything within 15 feet of where the front and side street lines meet is limited to 3 feet above curb level so drivers can see. The county says fence permits are usually issued within three days. Their page on residential fence permits has the detail.

Who actually applies for the permit?

The permit is taken out in the property owner's name. We will tell you what we believe your job needs before we start, so nothing comes as a surprise halfway through. If your property sits inside a town with its own permitting office, Rockville and Gaithersburg among them, check with the town rather than the county.

What about my HOA?

An HOA approval is a separate thing from a county permit, and plenty of jobs need both. Most associations want to see what the finished work will look like, where it sits on the lot, and what it is made of. Get that approval before we order material, because changing a stone colour on paper costs nothing and changing it on the ground costs real money.

Permit rules change. The two county pages linked above are the authority, not this page, and neither this page nor anything we say is legal advice. When a job is close to a threshold, we will say so and point you at the county.

Still wondering something?

Call (301) 978-6166, ask for a call back, or email JMLANDSCAPE14@gmail.com. A real person answers, and it is usually the one who will be doing the work.
