Fire rated sealant for Westdean homes and businesses

How we handle fire rated sealant in Westdean

A fire seal relies on being installed the way it was tested: correct depth, correct backing and a product suited to the surfaces. That detail is what we take care over. We work on plasterboard & masonry, door frames and service penetrations, and people most often call us about gaps flagged on a fire risk assessment and door frames with gaps between frame and wall.

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

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

What fire rated sealant looks like in Westdean

If you run a hotel, guest house or holiday let in a coastal place like Westdean, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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.

If you look after a building such as Ladycross School, service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Seaford station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

When to call us in Westdean

In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It may look fine, but it is not a fire-rated seal.

Keep an eye out for these signs:

  • Gaps flagged on a fire risk assessment
  • Open gaps behind door architraves
  • Open joints along the top of partitions
  • Fire stopping disturbed by later work

Community buildings like The Parish Church of All Saints are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking.

What your quote should include

  • When the joint can take water or movement
  • Whether the sealant suits the joint
  • What happens if the job turns out different
  • Whether they’re fully insured

Our hiring checklist

Keeping the joints in good condition

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

  • Keep pictures of seals that will be hidden
  • Flag any open gap you spot round a pipe or cable
  • Allow for resealing whenever new services are run
  • File the fire-stopping record where your assessor can find it

File the record of locations and products with your fire safety paperwork. It saves time at the next inspection or assessment.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the list grows.

What happens on the day

On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before we start. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere as small as Westdean, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We plan the order of work and access, floor by floor or flat by flat.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

Preparing for the visit

  • On commercial sites, let us know about site rules
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any previous sealing or DIY attempts

Advice

What the job involves on each surface

Service penetrations

A copper pipe, a cable and a plastic pipe can all need different fire-stopping details. Each one is sealed to the product’s tested detail, and tell you if sealant alone is not the right fix.

Masonry and concrete

Brick, block and concrete walls and floors are sealed with products tested in masonry. The gap is cleaned of dust first so the seal has something sound to bond to.

For landlords and businesses

Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

FAQs for Westdean

Do you work for landlords with property near Seaford station?

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

Is Westdean in your area for fire rated sealant?

Yes. Our work covers London and the South East, and Westdean is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.

Can you match the sealant colour?

We will suggest a colour to suit the surroundings. The choice depends on the product the joint needs.

How long does the job take?

It depends on the size of the job, but most jobs take from a few hours to a few days, depending on the number of gaps and the access. We will give you a better idea when we quote.

Do you remove the old sealant?

Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.

What sealant do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

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 work in flats, HMOs and commercial buildings?

Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.

When something else is needed

In fairness, there are a few things sealant will not fix:

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

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