Commercial sprinkler maintenance in Hertfordshire is planned work on offices, industrial and logistics units, and buildings converted from offices into flats. Sentry Sprinkler Protection carries out the quarterly, six-monthly and annual routines each system was designed to, proves the valve sets, alarms, pumps and tanks, and keeps the record your insurer and fire risk assessor ask for. St Albans and Watford are our regular Hertfordshire stops, 47 and 53 miles from our base. Sentry Sprinkler Protection does this work across England from its base in Kettering, ISO 9001 certified.

What a planned maintenance contract covers

  • Weekly: gauge readings, an alarm test and a pump start, held by your own team on our free weekly test log.
  • Quarterly and six-monthly: alarm valves and flow switches proved, water supplies checked and the pumps run, by us.
  • Annually: the full service, with the valve sets stripped and inspected, pump performance tested under flow and the tank condition recorded.
  • After every visit: a written report saying what was tested and what it read, with any defect photographed and priced on its own line.

Offices, comms rooms and conversions

Most of the county's commercial stock is office space, and an office system often carries something extra: a pre-action valve set over a server or comms room, which depends on its detection as well as its water. Both are proved on the visit, not only the wet system around them.

Where an office has been converted into flats, the residential parts are often a BS 9251 system with its own maintenance interval. Each part is maintained to its own standard, on one schedule, so the building has one date and one record.

Pumps and tanks are part of the routine

On industrial and logistics units the system often runs from its own tank and pump set rather than the town main. A system can pass every alarm test and still fail if the pump will not deliver its duty or the tank does not hold its level, so the water supply is serviced with the rest, not quoted as an extra later.

Planned on our Hertfordshire runs

Our Hertfordshire visits are planned in runs along the M1, alongside work already booked in St Albans and Watford, which is what keeps quarterly dates fixed from one year to the next. Isolations are agreed in writing beforehand and kept as short as the work allows.

This is a schedule, not a standby service. If your building needs an engineer on site within the hour, a contractor based in the county will serve it better, and we will tell you that before anything is signed.

    Each defect photographed and priced item by item, so you can decide what to fix.

  • The certificate

    Issued with the service, for your insurer and your fire risk assessment.

  • The weekly log

    A one-page sheet for the checks your own team does between our visits.

Switching from another contractor?

It happens often, and mid-year too. You do not have to wait for the old contract to run out to find out where your sprinkler system stands.

  1. Send what you have

    The last service report, the certificate, or a photo of the valve set. Whatever you have is enough to start.

  2. We survey before we quote

    What is installed, the standard it was designed to, whether the pumps make their duty and what the last reports found. Free, and written down.

  3. A clean record from our first visit

    If the old records are thin we say so and start a clean record, rather than sign off work we did not see.

When is your next visit due?

Pick the system and the month a contractor last came. You will see each routine, the date it falls due and anything that is already late.

Weekly checks are your own team's, logged on site. Our free weekly test log covers them on one page.

1 · The system

2 · The last contractor visit

Pick a month and a year to see your dates.

  • Every 3 months Quarterly test Water moving through the system proved to raise the alarm
  • Every 6 months Half-yearly service The interim contractor service
  • Every 12 months Annual service The full service, with the pump proved under flow
  • BS EN 12845

Counted from the visit you picked. If that was not the annual service, the annual may fall sooner. Your insurer or fire strategy can ask for more.

  • Lewis W. Sprinkler installation, warehouse

    Had them install a full sprinkler system across one of our warehouses, and couldn't be happier. They were professional from start to finish and the on-site team were genuinely friendly to work with. […] Highly recommend if you would need your building or warehouse properly fire-protected.

  • Mike C. Weekly maintenance, testing and repair

    Sentry Sprinkler Protection have recently taken over the weekly maintenance, testing and repair of the […] sprinkler equipment. They are providing a excellent service, good value and they are also very helpful when on site.

  • Sam E. Sprinkler pipework installation

    Couldn't recommend [Sentry] enough. Their work ethic, consistent efficient install of the pipework and overall approach to a project should be something every sub-contractor strives to mirror. Marius is incredibly approachable and methodical in his work with laydown areas kept very neat and tidy and all work carried out in a safe manner.

Questions about commercial sprinkler maintenance in Hertfordshire

Is commercial sprinkler PPM the same as sprinkler servicing?

Yes. Planned preventive maintenance is the BS EN 12845 routine set out as a contract: weekly checks your team holds, then the quarterly, six-monthly and annual visits we carry out on agreed dates in Hertfordshire.

Can you maintain a system another contractor installed?

Yes. We start with a survey of what is installed and what the last reports found, and agree the routine from there. Where the records are missing, we say so and start a clean record from our first visit.

What happens when a Hertfordshire visit finds a defect?

It goes on the report with a photograph and its own price, so you decide what is repaired and when. Anything that leaves the system unable to operate is reported to you before the engineer leaves site.

What happens when you ring

You talk to Marius Bucur, who runs the company and prices the work. Not a call centre.

Rather type?

  1. A few plain questions

    Usually four: what the building is, what system it has, when it was last serviced and the postcode. If you do not know some of it, that is normal.

  2. A straight answer

    Whether it is a job for us. If a building would be better served by someone closer, we will tell you that too.

  3. A free survey, on your dates

    Then a fixed price in writing, line by line. No survey fee, no obligation, nothing added afterwards.
