Fire rated sealant near Furnace Wood

Fire rated sealant in Furnace Wood, done properly

Deciding which gaps need fire stopping isn’t our role; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. We are often asked to deal with linear gaps at the head of walls and gaps left after a refit or conversion, on flats & HMOs, plasterboard & masonry and linear gaps.

Work in a small place like Furnace Wood is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.

Each job carries a 12-month guarantee, large or small.

How the job changes by surface

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We seal the gaps your assessor has identified room by room.

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. We use a product tested in that kind of wall for each gap size.

Commercial buildings in Furnace Wood

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

For site and facilities teams at buildings such as Felbridge Primary School, service openings in fire-resisting walls need checking after any refurbishment.

DIY versus a professional finish

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.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

What sealant work can’t fix

Sealant isn’t the answer to every problem, and we’ll tell you before we start. Sealant will not put right:

  • Walls or floors that weren’t built to resist fire
  • Issuing a fire rating or certificate for a building
  • Openings too large for sealant, which need batts, boards or another system

Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.

Where we work in Furnace Wood

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

What we do, step by step

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of gaps, and longer for a whole building, including the tidy-up. Somewhere like Furnace Wood needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Dust and loose debris are cleaned from each gap.
  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.

How to prepare

  • Keep children and pets away from the work area
  • Where the joints are inside, avoid wetting them before we arrive
  • Mention any tricky access

Advice

What affects the quote in Furnace Wood

For a quick quote, just ask. What matters most is:

  • Whether there’s mould to deal with
  • Whether the work is at height
  • Whether old sealant or filler has to be cut out
  • How much there is to do

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What we need to know

When you contact us, these details help:

  • A few photos by email, if you can
  • The problem you’ve noticed
  • Roughly how big the job is
  • How we’d reach the joints

If you’re in Furnace Wood and need fire rated sealant, phone 0345 464 0079 or send us an email. Tell us what the problem is and where, and we will agree the price before any work begins.

When to call us in Furnace Wood

Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.

People generally contact us when they notice something like this:

  • Gaps where walls meet ceilings or slabs
  • Gaps filled with a product that isn’t fire-rated
  • Damaged fire sealant left by other trades
  • Old fire sealant that has split or come away

If you let a flat or house near East Grinstead station, any gap left by new services in shared walls should be closed with a fire-rated product.

What your quote should include

  • Whether all the old sealant comes out first
  • Who does the work, and how experienced they are
  • What preparation is included
  • Whether VAT is included

10 questions to ask before you book

Common questions in Furnace Wood

Do you cover smaller places like Furnace Wood?

Yes, Furnace Wood is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

I let a flat near East Grinstead station. Can you help?

Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Do you carry out fire risk assessments?

No, assessment is not something we do. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.

Is standard sealant good enough for a fire gap?

No. It looks sealed but will not perform as fire stopping. A tested fire-rated product is needed, or ask us to do it.

Can you seal over the old sealant?

No, it will not last. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.

Do you seal gaps around fire door frames?

Yes. We seal the gap between the frame and the wall with a suitable fire-rated product. The door, its seals and closer are for a door specialist.

Do I have to be there?

That depends on where the joints are. Inside work needs someone to give us access.

Looking after it afterwards

Aftercare is simple:

  • Ask which product was used before you paint
  • Include fire stopping when you schedule refits
  • Include hidden areas like risers in routine checks
  • Store the list of sealed gaps with your building paperwork

Follow the cure time we give you before decorating over the sealant. Not every fire-rated sealant takes paint and we will tell you which one you have.

Any job that breaks through a wall or ceiling should include resealing. Doing it at the time avoids leaving gaps behind.
