Fire rated sealant near Coldwaltham

Do you need fire rated sealant in Coldwaltham?

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

Common reasons people contact us are:

  • Standard silicone or caulk in a fire-stopping gap
  • New service routes left unsealed after building work
  • Joints picked up in a fire-stopping survey
  • Unsealed gaps around fire door frames

Schools such as St James' CofE Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

  • What the cure time is

Our hiring checklist

How we handle fire rated sealant in Coldwaltham

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. We are often asked to deal with holes left by a change of layout and damaged fire sealant left by other trades, across flats & HMOs, door frames and plasterboard & masonry.

For holiday lets, converted business premises or a community building near Coldwaltham, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.

Our work is backed for twelve months.

Different surfaces, different methods

Plasterboard walls

Plasterboard partitions are common in flats, offices and conversions. We use a product tested in that kind of wall.

Service penetrations

New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in.

DIY sealant or a professional job?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

When something else is needed

It helps to know what we cannot do:

  • Assessing a building’s fire safety
  • Issuing a fire rating or certificate for a building
  • A wall that isn’t a fire-resisting element to begin with

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

What we seal

  • Plasterboard & masonry
  • Flats & HMOs

Coldwaltham: your questions answered

Do you cover smaller places like Coldwaltham?

Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can you help a landlord with a rental near Pulborough station?

Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.

How much does fire rated sealant cost in Coldwaltham?

Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.

How long does fire rated sealant take?

A typical job takes anything from a few hours to several days, depending on how many gaps there are. We’ll confirm how long when we quote.

Can new sealant go over the old?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Can you fill the gap behind a fire door frame?

Yes. We often seal open gaps hidden behind the architrave. The door and its fittings are a separate job for a door specialist.

Do I need to be at home?

Access is agreed with you when the job is booked. For inside work, that normally means someone being in.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Why act early in Coldwaltham

Sealant is not the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We’ll say so if a gap needs something other than sealant. In a small place like Coldwaltham, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Why book with us

  • Arbo and Everbuild products
  • Homes, businesses and hotels
  • 180+ five-star Google reviews
  • Anti-fungal silicone where joints get wet

Aftercare tips

To keep the joints looking good and working properly:

  • Make resealing part of every contractor’s brief
  • Get damaged fire seals looked at promptly
  • Look in service cupboards and ceiling voids from time to time
  • Photograph sealed gaps before they’re covered up

Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole.

The process

On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to several days, depending on how many gaps there are. In a small place like Coldwaltham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. Finally, we list where we worked and what we used, for your records.

Getting ready for the visit

  • Clear the area around the work
  • Mention if the joints have been sealed before
  • Keep children and pets away from the work area

What fire rated sealant looks like in Coldwaltham

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like The Parish Church of St Giles are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building. If you let a flat or house near Pulborough station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
