Fire rated sealant near Heyshott

How the visit works

You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. For a village or hamlet like Heyshott, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  1. First we work through your list or survey, measuring each gap and checking what it’s formed in.
  2. Old or unsuitable sealant is cut out and the gap cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Locations and products are noted so you have them on file.

How to prepare

  • On commercial sites, let us know about site rules
  • Mention any tricky access
  • Tell us about any previous sealing or DIY attempts

How we handle fire rated sealant in Heyshott

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. We work on linear gaps, plasterboard & masonry and door frames, and people most often call us about linear gaps at the head of walls and unsealed gaps around fire door frames.

If you have holiday lets, a converted barn used for business or a community building near Heyshott, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

Each job carries a 12-month guarantee, large or small.

What the job involves on each surface

Masonry and concrete

Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before the sealant goes in.

Door frames

The gap between a door frame and the wall around it needs sealing as well as the door itself. We fill it with a fire-rated product suited to the materials either side.

DIY versus a professional finish

If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Landlord and commercial work in Heyshott

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

Quotes for fire rated sealant in Heyshott

There’s no set price list. The quote depends on:

  • Any working-time requirements on site
  • The old material and how stubborn it is
  • Which sealant suits the joint
  • Whether there’s mould to deal with

The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Heyshott: your questions answered

Is Heyshott within the area you cover?

Yes. Heyshott is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

What guarantee comes with fire rated sealant in Heyshott?

All our work, in Heyshott and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Will we have a record of what was sealed?

Yes. We note each location and the product that went in.

Do you seal gaps around fire door frames?

Yes. We often seal open gaps hidden behind the architrave. Doors, seals and closers need a door specialist.

Do you offer different sealant colours?

Most of the time, yes. We will explain which colours are available.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned.

Can you do several jobs on one visit?

Yes, we can. More than one area can be quoted together.

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.

What we cannot put right

We’ll always be straight with you, so here’s what new sealant won’t do:

  • Large holes that need a different fire-stopping system
  • A wall that is not a fire-resisting element to begin with
  • Fire risk assessments, which need a qualified assessor

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Joints and surfaces we work on

  • Linear gaps
  • Plasterboard & masonry

Fire rated sealant in Heyshott: local notes

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.

Around Heyshott, as everywhere, fire rated sealant is only as good as the preparation behind it. Community buildings like The Parish Church of St James are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Keeping the joints in good condition

So the new joints stay in good condition:

  • File the fire-stopping record where your assessor can find it
  • Photograph sealed gaps before they’re covered up
  • Check whether a sealant can be painted before decorating over it
  • Tell trades working in the building that fire seals must be put back

Avoid covering a sealed gap with anything that is not part of the tested detail. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.

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