About Simfy Firesys

Passive fire protection
is the whole business.

No alarms, no sprinklers, no general contracting. One trade, done properly, in buildings that cannot stop working while we do it.

Who we are

We do one thing.
All of it.

Simfy Firesys is a passive fire protection contractor in Hyderabad. Not a general MEP firm with a fire division — this is the whole business. Shaft closing, coatings, sealants, cable barriers, and independent audits of work already in the ground.

The reason for specialising is simple. Passive fire work is judged on details nobody can see after handover: whether the wool was packed tight, whether the coating hit its thickness, whether the seal was photographed before the ceiling closed. A team that does this every day gets those right. A team doing it between other trades usually does not.

We work only with products that carry recognised certification — UL listed Armacell fire stop systems and CBRI certified Ameetuff mortar and intumescent products — so what goes in can be traced back to a tested system rather than a promise.

How we work

Four things we will not move on.

These are not slogans. They are the four places passive fire work usually goes wrong, and the reason we are strict about each one.

01
Certified products onlyUL listed Armacell systems and CBRI certified Ameetuff mortar, coatings and sealants. If a product cannot be traced to a tested system, it does not go into your building.
02
Photographed before it is hiddenEvery seal, every coated section, every joint — photographed with its location written down. Once the ceiling closes, that record is the only evidence anyone will ever have.
03
The preparation is not optionalRebar, mesh, mineral wool, surface prep, correct joint depth. These are the steps that get skipped to save a day, and they are the steps that decide whether the work holds.
04
We say when something is wrongIf another contractor's seal has failed, or the specified product is wrong for that opening, you will hear it from us plainly. You can decide what to do with that; you cannot decide about something nobody told you.
Straight answers

When we are not the right people.

It is worth saying out loud, because the wrong project for us is an expensive one for you.

GOOD FIT Call us
  • A multi-floor building with shafts, risers and a lot of service penetrations
  • A building that is finished and occupied and cannot close to be fixed
  • A handover or licence date you have to hit with documentation
  • An insurer, hospital accreditor or authority asking for evidence
  • Work already installed that you have no records for
  • A site anywhere in South India where the work can be blocked into one mobilisation
POOR FIT We will tell you
  • Three penetrations on one floor — call us and we will tell you what to check yourself
  • Alarms, sprinklers or hydrants — that is active fire protection, a different trade
  • A certificate without the work behind it — we do not do that
  • Lowest price as the only criterion — the way to be cheapest here is to apply less material
How we work

The building does not
have to stop.

This is the part most people assume is impossible, and it is the reason most passive fire work never gets done. The building is finished. It is occupied. Nobody wants to shut a floor to fix something they cannot see.

You do not have to. Passive fire work happens in the riser, above the ceiling and around the door frame — all places we can reach in the hours you are willing to give us. We have done it in occupied wards, trading hotels, live server rooms and offices full of staff, and on sites where three other trades were still working.

Tell us your constraint See how per building type
01
A building that is already finishedHandover is done, people have moved in, the ceilings are closed. We open the minimum, work the hours you give us, and put it back. Most of our work is in buildings that were signed off years ago.
02
A building that is runningA ward taking patients, a floor full of staff, a hotel selling rooms, a hall full of live racks. We take one riser, one corridor, one row at a time. Nothing closes.
03
A building where other trades are still workingWe sequence around them instead of stopping them. Our work needs the services finished and the ceiling still open — a narrow window. We plan for it rather than demanding it.
04
And we leave it the way we found itScreened working face, no dust carried into occupied areas, low-odour products near people, and the area cleaned at the end of every shift. Nobody should be able to tell we were there.
Where we work

Based in Hyderabad.
Working across South India.

Our team and our store are in Madhapur, Hyderabad. From there we travel — and for anything outside the city we plan the work in blocks so the mobilisation is worth the journey, for you and for us. No local offices, no local stock. We say that plainly rather than claiming branches we do not have.

FAQ

About working with us

?
Are you a fire safety consultant or a contractor?Both, but they are kept separate. We carry out installation work, and we also carry out independent audits. Where we audit a building, the report tells you what is wrong — appointing us for the remedial work is your choice, not a condition.
?
Which areas do you cover?Our team and store are in Madhapur, Hyderabad, and we work across South India — Telangana, Andhra Pradesh, Karnataka, Tamil Nadu, Kerala and Puducherry. In Hyderabad we are on site within 48 hours for a first look; outside the city we block the work so one mobilisation covers it properly.
?
What certifications do the products carry?The Armacell fire stop systems we use are UL listed. The Ameetuff mortar, intumescent coatings, sealants and pillows are CBRI certified, with testing at NTH and NABL-accredited laboratories. Product certificates come with the project file.
?
Can you work with our existing MEP contractor?Yes, and it works better that way. Most re-opened seals are caused by services being pulled after the passive package finished. Coordinating early avoids re-work on both sides.
?
Does the building have to shut down while you work?No — and that is most of what we do. We work in occupied wards, trading hotels, live server rooms and offices full of staff, taking one riser or one corridor at a time in the windows you give us. Where other trades are still on site, we sequence around them rather than stopping them.
