Trusted fire rated sealant in Pease Pottage

Fire rated sealant in Pease Pottage, done properly

Where services or frames pass through a fire-resisting wall or floor, the gap around them needs a fire-rated seal. We apply intumescent and fire-rated sealants to the manufacturer’s tested details for each gap, with a record of the products and locations if you need one. Typical jobs include gaps filled with a product that isn’t fire-rated and gaps where walls meet ceilings or slabs, across flats & HMOs, door frames and pipe & cable gaps.

For a pub, café, guest house or shop in or near Pease Pottage, its washrooms and kitchen need the same sealant care as any big building.

We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

DIY versus a professional finish

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • Certifying a building or signing off its fire safety
  • Fire doors that need new seals, closers or hardware
  • Construction that doesn’t provide fire resistance on its own

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

Commercial buildings in Pease Pottage

Pease Pottage is part of Crawley, one of the post-war new towns. Like the other new towns, Crawley was planned with its own areas for industry and business, so workplaces sit close to the homes. Their washrooms, kitchens and fire-rated joints need the same upkeep as anywhere. 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.

Letting a property close to Crawley station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Leave it or put it right?

Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Homes in smaller places like Pease Pottage can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

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.

What you get with us

  • Trusted Arbo and Everbuild sealants
  • 20+ years of sealant experience

What the job involves on each surface

Flats and HMOs

Converted houses often have gaps around old and new services. We seal the ones on your specification with a tested product and record where they are.

Linear gaps

Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run leaving no stretch unsealed.

Your questions about fire rated sealant in Pease Pottage

I let a flat near Crawley station. Can you help?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.

Will you come out to Pease Pottage?

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

What sealant do you use?

Each joint gets the product that suits it. Movement, water and weather all affect the choice.

Will it make a mess?

Not at all. The area is protected while we work and cleaned up afterwards.

What does intumescent mean?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.

Do you guarantee your work?

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

Can you seal over the old sealant?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

Can you do several jobs on one visit?

Yes. More than one area can be quoted together.

Do you need fire rated sealant in Pease Pottage?

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.

Common reasons people contact us are:

  • Open gaps behind door architraves
  • Linear gaps at the head of walls
  • Old fire sealant that has split or come away
  • Seals cut through by electricians, plumbers or data installers

If you look after a building such as Discovery New School, service openings in fire-resisting walls need checking after any refurbishment.

Questions to ask before booking

  • Whether they’re fully insured
  • Who turns up on the day
  • When the joint can take water or movement
  • How long the guarantee is

Choosing a sealant specialist

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Check whether a sealant can be painted before decorating over it
  • Never patch a fire seal with standard sealant
  • Keep photos of seals that will be hidden
  • Flag any open gap you spot round a pipe or cable

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is usually a straightforward job.

How the visit works

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes from a few hours to a few days, depending on the number of gaps and the access. A visit to Pease Pottage is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. Where the tested detail needs backing or fill, we fit it.
  4. We apply the fire-rated or intumescent sealant to the specified depth and tool it.
  5. Locations and products are noted so you have them on file.

Getting ready for the visit

  • On commercial sites, let us know about site rules
  • Tell us about any water getting in
  • Let us know about parking restrictions
