Trusted fire rated sealant in Greenstead Green

How the job changes by surface

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and record where they are.

Masonry and concrete

For masonry and concrete, we use a product tested in that substrate. The gap is cleaned of dust first so the sealant bonds.

Fire rated sealant in Greenstead Green, done properly

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That’s the part we focus on. If you’re dealing with gaps filled with a product that isn’t fire-rated and new service routes left unsealed after building work, we can put it right, whatever the surface.

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

A 12-month guarantee comes as standard, so you are covered after we’ve gone.

How the visit works

You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of gaps, and longer for a whole building for a typical job. Somewhere as small as Greenstead Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  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. Locations and products are written up and any gaps unsuitable for sealant are flagged.

Before we arrive

  • Where the joints are inside, avoid wetting them before we arrive
  • Clear the area around the work
  • Let us know about stairs, lifts or work at height

Related advice

DIY sealant or a professional job?

The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What we’re called out for in Greenstead Green

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

Common reasons people contact us include:

  • Linear gaps at the head of walls
  • Fire seals that have cracked with movement
  • New service routes left unsealed after building work
  • Open holes round services passing through fire walls

If you let a flat or house near Chappel & Wakes Colne station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Fire rated sealant in Greenstead Green: local notes

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.

If you look after a church, hall or community building such as Parish Church of St James, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as The Ramsey Academy are buildings too, and service openings in fire-resisting walls need checking after any refurbishment.

Your questions about fire rated sealant in Greenstead Green

Can you help a landlord with a rental near Chappel & Wakes Colne station?

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or send us an email with the details for a clear quote.

Will you come out to Greenstead Green?

Yes, Greenstead Green is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Do you work in flats, HMOs and commercial buildings?

Yes. Flats, HMOs, offices, schools and other occupied buildings are all part of our work. The order of work and access are planned with you.

Can you seal over the old sealant?

No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Will there be a smell?

There can be a smell while the sealant cures, but it fades. Opening a window helps.

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

No. Standard sealants are not made or tested to stop fire. If it’s been used, we remove it and use the right product.

Do I need to be at home?

For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.

What should I tell you?

A short description and the location. If we need more, we’ll ask.

Work for landlords, hotels and businesses

Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.

We also work for property managers and facilities teams. Several sites can be quoted together, and we’re fully insured.

What we cannot put right

Before you book, it’s worth knowing the limits:

  • Large holes that need a different fire-stopping system
  • Construction that does not provide fire resistance on its own
  • Doors that are not fire doors in the first place

If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

Surfaces we seal

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

Why it’s worth doing now in Greenstead Green

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that does not depend on other work. Older cottages and farmhouses around Greenstead Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.
