Fire rated sealant near Kingsclere

Why act early in Kingsclere

A quick fill with any sealant to hand isn’t fire stopping. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. In an older home around Kingsclere, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.

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.

Why Kingsclere clients choose us

  • 12-month guarantee on every job
  • Rated 4.9 stars on Google

Fire rated sealant in Kingsclere, done properly

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and the gap is resealed with a product tested for that use. Typical jobs include holes left by a change of layout and old fire sealant that has split or come away, on flats & HMOs, plasterboard & masonry and linear gaps.

Around a place like Kingsclere, halls, schools and small businesses all have washrooms and kitchens used by many people. Their sealant and fire-rated joints are as important as those in any bigger building.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

How we quote for fire rated sealant

There’s no set price list, because no two jobs are the same. The quote depends on:

  • Mould in or behind the old joints
  • How much there is to do
  • Whether old sealant or filler has to be cut out
  • When we can work, for business premises

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

What to tell us for a quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Photos by email, if that’s easy
  • How many joints, rooms or windows are involved
  • How we’d reach the joints
  • What’s wrong with the joints now

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Workplaces and buildings in Kingsclere

In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, 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 let a flat or house near Thatcham station, any gap left by new services in shared walls should be closed with a fire-rated product. Community buildings like Church of St Mary are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Can I do it myself?

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.

Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

What does fire rated sealant cost?

Size, access and the old material all affect the cost. Ask us for a quote.

How long will you be here?

Most jobs take a few hours for a handful of gaps, and longer for a whole building, including preparation and clearing up. Your quote will say how long we expect yours to take.

Where do you work from?

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

What’s the difference between intumescent and fire-rated sealant?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.

What happens on the day

Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours for a handful of gaps, and longer for a whole building, depending on the size of the job. In a smaller place like Kingsclere, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  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 and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your records.

Before we arrive

  • Mention any leaks or damp you’ve noticed
  • Keep pets and children clear of the area while we work
  • Move anything stored near the joints

Common problems we fix in Kingsclere

Movement in the structure can open gaps too: a seal that cracks or pulls away leaves a path for smoke. Damage from cleaning, knocks and maintenance adds to it.

If you can see any of these, it’s time to have the joints looked at:

  • Holes left by a change of layout
  • Unsealed gaps where pipes and cables go through a wall
  • Open gaps behind door architraves
  • Gaps flagged on a fire risk assessment

If you look after a building such as Kingsclere Church of England Primary School, fire-stopping around service openings should be restored whenever new services go in.

What your quote should include

  • How long the guarantee is
  • What product goes in the joint
  • How much experience the applicator has
  • What the quote includes, VAT included or not

Our hiring checklist

Different surfaces, different methods

Masonry and concrete

Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.

Plasterboard walls

Many fire-resisting walls in flats, offices and conversions are plasterboard. The sealant has to be one tested in plasterboard.

Honest limits

New sealant cannot fix everything, and we’ll tell you before work begins. Sealant will not put right:

  • Construction that does not provide fire resistance on its own
  • Issuing a fire rating or certificate for a building
  • Fire risk assessments, which need a qualified assessor

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