Paver patios, walkways, retaining walls & fire pits — designed and built to survive Northern Virginia clay and freeze-thaw winters. One crew from design to done, serving all of Ashburn.
A patio in Ashburn has to survive two things: Northern Virginia's freeze-thaw winters and our heavy clay soil. That's why the part you never see — excavation, grading, gravel base, compaction — matters more than the pavers on top. We build the base right so your patio is still flat and level in year ten, not heaving by year two.
Green Leaves designs and builds hardscaping across Ashburn — full backyard patios, compact townhome patios, and the retaining walls that turn NOVA's sloped lots into usable yard. One licensed, insured crew from design to done, backed by the same 5.0-star service our lawn care clients already know across Ashburn Farm, Ashburn Village, Brambleton, Broadlands, Belmont, and Loudoun Valley Estates.
Our clay holds water, and water is what destroys hardscaping. Every project we build is pitched to drain away from your foundation, sits on a properly compacted stone base, and — where the yard needs it — gets drainage built in: French drains, channel drains, or a dry creek bed that turns a soggy corner into a feature. If your current patio puddles or your basement wall gets damp after storms, tell us during the quote and we'll solve both at once.
Some of our favorite Ashburn projects are the small ones: a 200-square-foot paver patio, a walkway, low seating wall, and privacy planting that turn a bare townhome strip into the best room of the house. Small yards need tighter planning, not less of it — and because we're also landscapers, the plants, sod, and mulch that finish the space come from the same crew.
1. On-site design visit — we measure, talk through materials, and sketch the layout. 2. Firm written quote — fixed price, no surprises. 3. The build — most patios take days, not weeks, and we protect your lawn while we work. 4. Final walkthrough — we're not done until you'd recommend us to your neighbor.
It depends on size, material, and access to your yard, so we price it in person — a free on-site design visit, then a firm written quote. The number we give you is the number you pay. No allowances, no mid-project surprises.
Most standard patios don't. Taller retaining walls and certain structures can. We flag any permitting requirement during your quote and handle the process when a project needs it — you won't have to chase the county yourself.
For our freeze-thaw winters, pavers. A slab cracks and the whole thing shows it; pavers flex with the ground, and if one ever settles or stains, we lift and reset that single paver. That's why nearly all of our builds are pavers or natural stone.
Most residential patios take 2–5 working days once materials arrive. We give you the schedule with your quote and confirm your start date before we break ground — and we leave the site clean every evening.
Often, yes. If the pavers are in good shape, we can lift them, rebuild the base that failed underneath, and re-lay the same material for far less than a new build. We'll tell you honestly which option makes sense when we see it.
The right timing matters more than the product. Here's the schedule we actually follow across Ashburn — based on our zone 7 climate, clay soil, and cool-season lawns.
Most NOVA lawns are cool-season tall fescue, and fescue does almost all of its root-building in fall. The two most valuable feedings are early September and again in late October to early November. A single light feeding in April is fine, but skip heavy nitrogen in summer — it stresses fescue and feeds crabgrass instead of your grass.
Late August through mid-October is the prime window. The soil is still warm enough for fast germination, the nights are cooling, and there's far less weed competition than in spring. Aim to get seed down by mid-September for the strongest fill-in before winter. Spring seeding (March–April) is a distant second and usually gets crowded out by crabgrass.
The main mulch application is mid-to-late spring — April into May — once the soil has warmed and early weeds are cleared. Refresh in fall if beds look thin. Keep mulch 2–3 inches deep and pull it a few inches back from trunks and stems; “mulch volcanoes” piled against bark trap moisture and cause rot.
Wait until after the average last frost — around April 15–20 — before putting out warm-season annuals like petunias, marigolds, and impatiens. Cool-season color such as pansies and violas can go out in late March or again in fall. Perennials, trees, and shrubs establish best planted in fall (September–October) or early spring, and spring bulbs like tulips and daffodils go in the ground in October–November.
Core-aerate cool-season lawns in the fall — September into October — ideally right before overseeding so the seed drops into the holes. Fall aeration relieves the summer compaction that NOVA's heavy clay builds up and sets up thick spring growth. Spring aeration is possible but can open the door to summer weeds.
