Fire rated sealant in Sherfield English, done properly

We do not assess buildings or decide what fire stopping is needed; that comes from your fire risk assessor, designer or building control. Our part is applying the specified sealant carefully, to the right depth and with the right backing. If you are dealing with fire stopping disturbed by later work and open joints along the top of partitions, we can help, on plasterboard & masonry, pipe & cable gaps and service penetrations alike.

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

The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or email us.

Commercial buildings in Sherfield English

Rented homes near Mottisfont & Dunbridge station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

Quotes for fire rated sealant in Sherfield English

You will get a clear quote before any work starts. It’s based on:

  • How easy the joints are to reach
  • The product the joint needs
  • How much old sealant there is and how hard it is to remove
  • How much there is to do

What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

What we need to know

To make quoting easier, please include:

  • How many joints, rooms or windows are involved
  • Any access issues, like height or stairs
  • Pictures of the joints, sent by email
  • Whether it has been sealed before

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.

We work for landlords and agents as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.

Your questions about fire rated sealant in Sherfield English

Will you come out to Sherfield English?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you work for landlords with property near Mottisfont & Dunbridge 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 any work starts.

Do I need to be at home?

We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Do the sealants smell?

Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.

Is there a guarantee?

Yes, for a year. If there’s a problem with our work in that time, tell us and we’ll put it right.

Do you take on fire stopping in schools and offices?

Yes. Occupied flats, HMOs, offices and schools are all fine. Early starts or out-of-hours work can be arranged.

Should I try DIY first?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.

When to call us in Sherfield English

A lot of fire stopping is out of sight: above ceilings, inside risers and behind panels. Out of view, damage sits unnoticed until someone inspects.

Keep an eye out for these signs:

  • Door frames with gaps between frame and wall
  • Fire seals that have cracked with movement
  • Gaps where walls meet ceilings or slabs
  • Gaps around pipes and cables through fire-resisting walls

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

Before booking anyone

  • How the joint is cleaned and prepared
  • Who does the work, and how experienced they are
  • Whether the sealant suits the joint
  • The length of the guarantee

Choosing a sealant specialist

Surface by surface

Flats and HMOs

In occupied buildings, we plan the order of work with you. Access to flats and common areas is agreed in advance to keep disruption down.

Service penetrations

Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. We follow the manufacturer’s tested detail for each.

How the visit works

We keep the work tidy and contained to the area we are working on, so you can get on with your day. Expect the work to take from a few hours to a few days, depending on the number of gaps and the access, and we explain the cure time before we leave. In a small place like Sherfield English, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  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 and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products for your files.

Preparing for the visit

  • Tell us if parking is tricky
  • Plan for the work area to be out of bounds to pets and children
  • For business premises, tell us about site rules or sign-in

DIY versus a professional finish

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 fails, we can still redo it.

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.

How to look after the new joints

Looking after new joints is easy, and it makes a real difference:

  • Keep pictures of seals that will be hidden
  • 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

Don’t add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.
