Fire rated sealant near Offham

How we handle fire rated sealant in Offham

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. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. We’re often asked to deal with open gaps behind door architraves and fire stopping disturbed by later work, on service penetrations, flats & HMOs and pipe & cable gaps.

If you have holiday lets, a converted barn used for business or a community building near Offham, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Keeping the joints in good condition

Good habits help new joints last longer. Our tips:

  • Look in service cupboards and ceiling voids from time to time
  • Report cracked or damaged seals as soon as you notice them
  • Keep the record of products and locations with your fire safety documents
  • Keep pictures of seals that will be hidden

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some can’t, so ask us which we used.

Small gaps around services are simple to deal with while there are only a few. Over time, more work adds more holes and the job gets bigger.

When it isn’t the sealant

We won’t take on work that won’t last, so here’s what sealant can’t put right:

  • Fire doors that need new seals, closers or hardware
  • Openings too large for sealant, which need batts, boards or another system
  • Assessing a building’s fire safety

If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before you book.

FAQs for Offham

Can you help a landlord with a rental near West Malling station?

Yes, we work for landlords and letting agents. Just call 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.

Do you work in hotels near Offham?

Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.

Will you leave a mess?

No. We protect the surfaces around the joints, and we tidy up before we go.

Do you come to Offham?

Yes. We are based in Crawley and work across South East England, London and Scotland, and that includes Offham.

What does intumescent mean?

Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.

What do you need from me for a quote?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply phone 0345 464 0079 or send us an email.

Is standard sealant good enough for a fire gap?

No. Ordinary silicone, caulk or foam isn’t tested as fire stopping. If it’s been used, we remove it and use the right product.

Do you carry out fire risk assessments?

No. We work from the specification you give us, and apply each product to its tested details.

Why act early in Offham

Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap is not suitable for sealant, we’ll tell you. Around Offham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Can I do it myself?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

The process

At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on how many gaps there are, depending on the amount of work. Somewhere as small as Offham, access is often the only tricky part. 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.
  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.

Getting ready for the visit

  • Mention any tricky access
  • Clear items away from the joints we are working on
  • On commercial sites, let us know about site rules

Advice

When to call us in Offham

In some buildings the gap was filled with the wrong thing in the first place: general-purpose foam, everyday silicone or caulk in a place that needed a tested fire seal. It looks sealed, but it isn’t fire-rated.

These are the problems we are asked about most:

  • Joints picked up in a fire-stopping survey
  • Cracked or shrunken fire-rated sealant
  • Damaged fire sealant left by other trades
  • Gaps around pipes and cables through fire-resisting walls

If you let a flat or house near West Malling station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
