Fire rated sealant near North Crawley

Can I do it myself?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

How we handle fire rated sealant in North Crawley

Bigger jobs can be worked through in stages, flat by flat or floor by floor, noting the locations and products as we go. It gives you a list to keep with the building’s fire safety documents. We work on service penetrations, flats & HMOs and door frames, and the jobs we see most are sealant items on a fire risk assessment action list and fire seals that have cracked with movement.

In a village or hamlet like North Crawley, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.

There’s a 12-month guarantee on every job, large or small.

FAQs for North Crawley

Will you come out to North Crawley?

Yes, North Crawley is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

What guarantee comes with fire rated sealant in North Crawley?

All our work, in North Crawley and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Do you offer different sealant colours?

We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.

What does intumescent mean?

Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all, and the choice depends on the gap.

Should I try DIY first?

It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Can you tell me how many minutes the seal will last?

That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we apply a product tested for it.

Do you seal gaps around fire door frames?

Yes, where the gap suits a sealant detail. Our work is the gap around the frame.

Looking after it afterwards

A little care helps the new joints last. Our advice:

  • Report cracked or damaged seals as soon as you notice them
  • Keep the record of products and locations with your fire safety documents
  • Do not fill fire-stopping gaps with ordinary foam or silicone
  • Tell trades working in the building that fire seals must be put back

Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. We can tell you which product we used.

Leave a fire-stopping gap open and smoke can move through the building much more easily. Sealing it early is a simple step to take.

How we quote for fire rated sealant

Every job gets its own quote. This is what makes a difference:

  • How much old sealant there is and how hard it is to remove
  • Any working-time requirements on site
  • Whether there’s mould to deal with
  • How many areas need sealing

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Asking for a quote

Photos help, but a description is a good start. Try to tell us:

  • What’s wrong with the joints now
  • Where the job is, and your postcode
  • A few pictures by email, if you can
  • How we’d reach the joints

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we’ll explain what’s involved and give you a clear quote.

Landlords, agents and businesses in North Crawley

We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.

Workplaces and buildings in North Crawley

Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.

For site and facilities teams at buildings such as North Crawley CofE School, service openings in fire-resisting walls need checking after any refurbishment. If you look after a church, hall or community building such as Church of St Firmin, older buildings that have had new heating or wiring often have service gaps worth checking.

Surface by surface

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. The gap is cleaned and backed where required.

Why it’s worth doing now in North Crawley

Leaving a gap until a refurbishment comes round can mean years with it open. On its own, sealing it now is a small job that doesn’t depend on other work. Around North Crawley, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

On the day, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work usually takes anything from a few hours to several days, depending on how many gaps there are. For a village or hamlet like North Crawley, the journey is planned in advance: let us know about lanes, gates and parking.
