Water Features & Fountains in Mount Vernon, Virginia
We design water features to disappear into the hardscape and the maintenance schedule alike. That means pondless waterfall vaults built with enough reservoir capacity to ride out our humid Virginia summers without constant top-offs, energy-efficient pumps wired and GFCI-protected to code, and basin liners and plumbing runs installed below frost depth so a January freeze doesn't crack a line you can't see until spring.
The Short Answer
A pondless waterfall or bubbling urn fountain in Mount Vernon typically runs $2,500–$6,000, a mid-size pondless waterfall feature $6,500–$18,000, and a full pond or estate-scale water feature $18,000–$45,000+ — driven mainly by basin size, pump/filtration capacity, and stone tier. In Fairfax County, any pond or basin over 24 inches deep is legally treated as a swimming pool and requires permits plus safety fencing, while shallower basins avoid that trigger. Most single-feature installs take 1–3 weeks of active build time once design and any HOA architectural review (statutory 45-day maximum in Virginia) and county permitting are cleared.

Mount Vernon, Answered
Water Features & Fountains in Mount Vernon — Common Questions
How much does a water feature or fountain cost in Northern Virginia?
A bubbler or urn fountain typically runs $2,500–$6,000, a pondless waterfall $6,500–$18,000, and a full pond or estate-scale water feature $18,000–$45,000+. Size, pump/filtration capacity, and stone tier are the biggest drivers of final price. Serving Mount Vernon and all of Fairfax County. Our crews work Mount Vernon regularly, so scheduling is usually available within the week outside the spring rush — and every visit ends with before-and-after photos of the finished work.
Do I need a permit for a pond or fountain in Fairfax County?
It depends on depth and disturbance. A basin under 24 inches deep generally avoids swimming-pool classification and its permit/fencing requirements. Larger builds disturbing more than 2,500 sq ft need an approved Erosion & Sediment Control plan before work starts. We handle this assessment during design. Serving Mount Vernon and all of Fairfax County.
How long does HOA approval take for a water feature?
Under Virginia's Property Owners' Association Act, an HOA architectural committee must issue a written decision within 45 days of receiving a complete application — if they miss that window, the request is deemed approved by statute. We prepare your submittal package to keep that clock moving. Serving Mount Vernon and all of Fairfax County.
How much maintenance does a water feature actually need?
Pondless waterfalls and urn fountains need the least upkeep — periodic water top-off, an autumn cleaning, and a pump check. Full ponds with fish and plants need more regular attention to water chemistry and filtration. We size every system so ongoing maintenance stays realistic for your schedule. Serving Mount Vernon and all of Fairfax County.
Can a water feature run through a Northern Virginia winter?
Yes, with the right engineering. Basins need proper depth and base prep to handle our clay soil's freeze-thaw cycles, and most clients either run the feature through winter with a de-icer or do a simple seasonal shutdown. We cover both options during your design consultation. Serving Mount Vernon and all of Fairfax County.
What's the difference between a pondless waterfall and a full pond?
A pondless waterfall recirculates water through a hidden underground basin with no standing surface water — lower maintenance, no fish, and generally simpler from a permit standpoint. A full pond holds visible standing water, can support fish and plants, and typically involves more filtration and, at larger depths, more regulatory review. Serving Mount Vernon and all of Fairfax County.
How long does installation take from design to finished water feature?
Most single-feature projects (fountain or pondless waterfall) take 1–3 weeks of active construction once design is finalized. Add county permit review (2–6 weeks depending on county) and HOA review (up to 45 days) where applicable — we sequence these so your project doesn't stall waiting on paperwork. Serving Mount Vernon and all of Fairfax County.
