About our fire rated sealant in Green Street Green

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have damaged fire sealant left by other trades and cracked or shrunken fire-rated sealant, we can put it right.

For a small place like Green Street Green, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.

We stand behind the work with a one-year guarantee, so you are covered after we have gone.

What we cannot put right

Honest advice matters more to us than a booking, so here’s what new sealant won’t do:

  • Construction that does not provide fire resistance on its own
  • Fire risk assessments, which need a qualified assessor
  • Openings too large for sealant, which need batts, boards or another system

Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.

Surfaces we seal

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

What we do, step by step

Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. In a small place like Green Street Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. We record what was done and flag anything that needs a different system.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions

Workplaces and buildings in Green Street Green

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For landlords with property near Longfield station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

FAQs for Green Street Green

Will you come out to Green Street Green?

Yes, we do. 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 Green Street Green in your area for fire rated sealant?

Yes, Green Street Green is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing.

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.

I rent my home. Can I book you?

Yes, but check with your landlord or agent first. Landlords are often happy for the work to be arranged.

Are you ARBOMaster approved?

Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

How do I get a quote for fire rated sealant in Green Street Green?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

Can you fill the gap behind a fire door frame?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

Can you work in occupied buildings?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we’ll plan around it.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Check risers, ceiling voids and cupboards during building checks
  • File the fire-stopping record where your assessor can find it
  • Keep photos of seals that will be hidden
  • Never patch a fire seal with standard sealant

Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded so the item can be closed.

How we quote for fire rated sealant

The quote reflects the job in front of us. We look at:

  • Mould in or behind the old joints
  • When we can work, for business premises
  • How many areas need sealing
  • The type of sealant required

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Asking for a quote

There’s no need for technical detail. Just tell us:

  • A few pictures by email, if you can
  • Where the property is
  • If someone has resealed it before
  • How we’d reach the joints

Do you need fire rated sealant in Green Street Green?

Gaps around door frames are easily missed. The gap between the frame and the wall is hidden behind the architrave, so it’s easy to leave unsealed when doors are changed.

If you can see any of these, it’s time to have the joints looked at:

  • Fire seals that have cracked with movement
  • Damaged fire sealant left by other trades
  • Standard silicone or caulk in a fire-stopping gap
  • Gaps left after a refit or conversion

Managing a site like Greenlands Primary School? Then service openings in fire-resisting walls need checking after any refurbishment.
