Fire rated sealant for Trench Green homes and businesses

What we do, step by step

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Trench Green, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Before starting, we go through the specification or action list with you.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. Every location is recorded with the product used for your files.

Preparing for the visit

  • Keep children and pets away from the work area
  • Let us know about earlier repairs to the joints
  • Let us know if you’ve seen damp or leaks

Fire rated sealant for homes and businesses in Trench Green

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you’re dealing with gaps left after a refit or conversion and unsealed gaps where pipes and cables go through a wall, we can put it right, on plasterboard & masonry, linear gaps and pipe & cable gaps alike.

In a village or hamlet like Trench Green, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Fire rated sealant around Trench Green

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.

For buildings such as Church of St Margaret and Bardolf Aisle, older buildings that have had new heating or wiring often have service gaps worth checking.

Trench Green is about 2 miles north-west of Caversham, in Reading. Our applicators cover fire rated sealant for householders, landlords and businesses in Trench Green and nearby. Trench Green is one of 34 towns and villages in Reading we cover for fire rated sealant.

Signs you need fire rated sealant in Trench Green

Much fire stopping is hidden: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.

Signs it’s time to call us include:

  • Door frames with gaps between frame and wall
  • Holes left by a change of layout
  • Fire stopping disturbed by later work
  • Joints picked up in a fire-stopping survey

Rented homes near Tilehurst station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Questions to ask before booking

  • Whether you can choose the colour
  • Whether they seal over old material or remove it
  • Is VAT in the price?
  • What happens if they find a problem under the old sealant

10 questions to ask before booking

When something else is needed

To be straight with you, some problems need a different trade:

  • Doors that aren’t fire doors in the first place
  • Deciding what fire stopping a building needs
  • Large holes that need a different fire-stopping system

If in doubt, phone 0345 464 0079 or email us and we’ll say what we think before booking.

Surfaces we seal

  • Linear gaps
  • Flats & HMOs
  • Pipe & cable gaps
  • Plasterboard & masonry
  • Service penetrations
  • Door frames

Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together.

How to look after the new joints

Aftercare is simple, and it makes a real difference:

  • Plan fire stopping into any work that goes through walls or floors
  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Tell trades working in the building that fire seals must be put back
  • Look in service cupboards and ceiling voids from time to time

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

  • The address or postcode of the job
  • What the problem is, such as mould, gaps, leaks or cracking
  • Any previous sealing or DIY work

How the job changes by surface

Flats and HMOs

In occupied buildings, we plan the order of work with you. We agree access to each flat and the common parts before work begins to keep disruption down.

Masonry and concrete

Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.

Trench Green questions

Can you help a landlord with a rental near Tilehurst station?

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.

Is Trench Green within the area you cover?

Yes, Trench Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is it OK to seal over old sealant?

No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

Will it make a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

Is intumescent sealant the same as fire-rated sealant?

Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

What does fire rated sealant cost?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

Can I use normal mastic around a pipe through a fire wall?

No. Where a fire-rated seal is needed, it has to be a product tested for that use fitted to the maker’s details.

Do you seal gaps around fire door frames?

Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door leaf and its hardware need a door specialist.
