DC has a growing stock of sprinklered houses and almost nobody minding them.
Every year of the sprinkler requirement adds another ring of houses to the District’s installed base: new rowhouses, townhouse rows, converted two-flats, ADUs. The systems are quiet by design, which means they are also ignored by default, and the first time most owners think about theirs is a resale, a renovation, or a drip. That is the half of the trade this page is about, and it is work we do at house scale, one unit at a time, with a written report at the end.
The resale check
A sprinklered DC house changing hands deserves an inspection with a written report. Weeping heads, painted heads, and valves found closed after a sale are the repair calls we handle most, and every one of them is cheaper found during the inspection period than after the keys change hands. Buyers and agents increasingly ask for the paperwork; we produce the kind they can actually read.
Two-flats, condos, and who owns the problem
The conversion wave is creating small buildings whose associations inherit inspection obligations nobody mentioned at settlement. The usual split runs unit piping to the owner and shared risers to the association, with the documents deciding the details. We inspect single units, whole buildings, or a row for an HOA on one visit, and we put the responsibility answer in writing alongside the findings.
Repairs at house scale
The commercial fire protection companies that dominate this region do not want a single rowhouse call. We do. Head replacement, small leaks, gauge and valve issues, and backflow preventer testing with the paperwork filed. Pricing for the recurring work is flat-rate and quoted before we come; the numbers live on the cost page.
Inspection questions, answered
My sprinklered DC house is changing hands. What should happen?
A fire sprinkler inspection with a written report, the same resale check we run across the region. Heads checked for paint, corrosion, and clearance, valves and gauges verified, and a report the buyer, the seller, and the agent can all read. It is a single visit and it is priced flat, quoted before we come.
A sprinkler head is dripping. What do I do right now?
Close the sprinkler control valve, usually near where the water service enters the house, and call. A weeping head means corrosion or a nicked seal, and heads do not heal on their own. Replacement is normally a same-week job and a modest one.
A painter painted over my sprinkler heads. Is that actually a problem?
Yes. Paint on a head can slow or block it from operating, and painted heads are a standard write-up in any inspection. The fix is replacement of the affected heads, not cleaning. It is one of the two most common repairs we make, alongside valves found closed after a sale.
Who is responsible for the system in a two-flat or small condo?
Two-flats and condo buildings carry inspection obligations their associations are often surprised to inherit. The usual split runs unit piping to the owner and shared risers to the association, with the documents deciding. We put the answer in writing so the owner and the association both know where the line is.
What is backflow testing and do I need it?
The backflow preventer keeps water that has been sitting in sprinkler pipe from flowing back into the drinking supply, and where one is installed it has a test due date. We test and file the paperwork as a flat-rate visit.
Leak, resale, or a system nobody has looked at?
If a head is dripping right now, close the sprinkler control valve first. Then call.
