What a residential sprinkler system costs in Northern Virginia
We publish our pricing because the alternative, making you call three companies to triangulate a fair number, wastes your week. This is the same table we quote against everywhere we work. Use it to check our bid or anyone else’s.
| Work | Published range | What moves the number |
|---|---|---|
| New construction 13D system | $1.35 to $1.60 per sprinklered sq ft | Floor plan complexity, ceiling types, service line sizing |
| Retrofit, existing house | $2 to $7 per sprinklered sq ft | Attic and wall access, finishes to open and close |
| Well property add: tank and pump | $3,000 to $6,000 | Tank size and pump from the hydraulic calculation |
| Inspection with written report | Flat visit rate, quoted before we come | Unit count for HOA rows, access |
| Head replacement, small repairs | Quoted per job, usually modest | Head count, matching discontinued heads |
| Backflow preventer test | Flat test rate, paperwork filed | Device type and location |
Worked example
A 2,400 square foot new build on public water lands between $3,200 and $3,900. The same house on a well in Great Falls or western Loudoun adds the tank and pump, so plan on roughly $6,200 to $9,900 all in. If the system is being installed to satisfy a fire access requirement, compare that range to the driveway rebuild or water main extension it replaces. That comparison is the whole story of the access alternative, and it is why the sprinkler answer keeps winning plan reviews.
Why retrofit spreads so wide
New construction pipe goes in before drywall, so the labor is predictable. Retrofit pricing lives and dies on access: an open attic over a single story house sits at the bottom of the range, a finished four story townhome with plaster ceilings sits at the top. We quote retrofit only after seeing the house, and the written number holds.
What the quote includes
Design, the hydraulic calculation, the permit filing with the county or city, installation, and the acceptance test. Our Virginia jobs are handled by crews licensed for Virginia work, and pricing does not change when the state line does.
