Fire rated sealant for Clanfield homes and businesses

Fire rated sealant in Clanfield, done properly

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We work on flats & HMOs, pipe & cable gaps and service penetrations, and people most often call us about sealant items on a fire risk assessment action list and new service routes left unsealed after building work.

Work in a small place like Clanfield is planned ahead, journey included, so it can be fitted around guests, clients or events where possible.

Your job is guaranteed for a year, as with all our work.

Fire rated sealant around Clanfield

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. Clanfield has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.

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

Quotes for fire rated sealant in Clanfield

There’s no set price list. The quote depends on:

  • How many areas need sealing
  • Which sealant suits the joint
  • How much old sealant there is and how hard it is to remove
  • Any working-time requirements on site

Doing several joints on one visit is usually more efficient than separate visits. You’ll get one clear quote for the whole job.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • The type of property
  • What the problem is, such as mould, gaps, leaks or cracking
  • Roughly how big the job is
  • Photos by email, if that is easy

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.

What sealant work can’t fix

To be straight with you, some problems need a different trade:

  • Assessing a building’s fire safety
  • Doors that are not fire doors in the first place
  • A wall that isn’t a fire-resisting element to begin with

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

Where we work in Clanfield

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

How the job changes by surface

Flats and HMOs

Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and record where they are.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.

Can I do it myself?

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.

If you do try it yourself, take your time over the 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.

Your questions about fire rated sealant in Clanfield

Is Clanfield within the area you cover?

Yes, we do. 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 take on hotel work around Clanfield?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

What do you need from me for a quote?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or drop us an email.

Will the old sealant be removed?

Yes. We cut out all the old sealant and clean the joint before resealing.

Can I add another job to the visit?

Yes, and it often makes sense. Doing several areas at once is normally more efficient.

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Is intumescent sealant the same as fire-rated sealant?

An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.

Signs you need fire rated sealant in Clanfield

Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.

Signs it’s time to call us include:

  • Fire stopping disturbed by later work
  • Unsealed gaps around fire door frames
  • Standard silicone or caulk in a fire-stopping gap
  • Unsealed gaps where pipes and cables go through a wall

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

How it works

When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before any work starts. The work generally takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Clanfield, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  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. Unsuitable material such as ordinary foam or silicone is cut out.
  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 records.

Getting ready for the visit

Advice

How to look after the new joints

After the cure time, these simple habits help:

  • Never patch a fire seal with standard sealant
  • Make resealing part of every contractor’s brief
  • Plan fire stopping into any work that goes through walls or floors
  • Keep pictures of seals that will be hidden

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.

A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
