Fire rated sealant in Ashurst Wood

Fire rated sealant for homes and businesses in Ashurst Wood

We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. What we do is apply the right product to that specification, properly and neatly. If you are dealing with gaps flagged on a fire risk assessment and fire stopping disturbed by later work, we can help.

For a small place like Ashurst Wood, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

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

Common problems we fix in Ashurst Wood

Sealant applied too thin, without the backing its detail needs, or onto dust won’t perform as it was tested. Rushed fire stopping is common particularly when it was the last job before handover.

Keep an eye out for any of the following:

  • Gaps filled with a product that isn’t fire-rated
  • New service routes left unsealed after building work
  • Gaps flagged on a fire risk assessment
  • Linear gaps at the head of walls

For landlords with property near East Grinstead station, any gap left by new services in shared walls should be closed with a fire-rated product.

Questions to ask before you book

Quotes for fire rated sealant in Ashurst Wood

You’ll get a clear quote before work begins. It takes into account:

  • Which sealant suits the joint
  • The size of the job
  • Any mould that needs treating
  • When we can work, for business premises

There are no prices on our website, because each job is priced on what it involves. Call for a quick quote.

What we need to know

When you call or email, it’s useful to know:

  • A few photos by email, if you can
  • How many joints, rooms or windows are involved
  • Where the property is
  • How we’d reach the joints

Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will talk you through the work.

Honest limits

We will always be straight with you, so here’s what new sealant won’t do:

  • Walls or floors that weren’t built to resist fire
  • Fire risk assessments, which need a qualified assessor
  • Problems with the door itself rather than the gap around the frame

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.

Surfaces we seal

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

Should I try it myself first?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

Fire rated sealant in Ashurst Wood: 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 work to the specification you’re given, installing the product to its tested details.

For buildings such as St Dunstan, service openings in its walls need the right fire-rated sealant, as in any building. If you look after a building such as Ashurst Wood Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Your questions about fire rated sealant in Ashurst Wood

Do you work for landlords with property near East Grinstead station?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.

Can you do fire rated sealant in Ashurst Wood?

Yes, Ashurst Wood is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we are using.

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

No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service and we can apply it for you.

Do you provide details of the products used?

Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.

Does someone need to be in?

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Will it make a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Do you certify the fire stopping?

Ratings and certificates aren’t something we issue. The performance comes from the product’s tested details and the specification from your assessor or designer, and we install to them.

Work for landlords, hotels and businesses

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

How the visit works

When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Ashurst Wood, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used.

Preparing for the visit

  • Mention any tricky access
  • Tell us if parking is tricky
  • Tell us about any water getting in

Different surfaces, different methods

Plasterboard walls

In plasterboard walls, the condition of the board edge matters. Crumbling edges are cleaned back before the sealant goes in.

Service penetrations

Service penetrations are where new gaps often appear. We clean out what’s there and reseal to the right depth with backing where the detail needs it.
