About our fire rated sealant in Ansty

In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. We seal them with a product tested for that kind of gap. We work on linear gaps, plasterboard & masonry and door frames, and the jobs we see most are sealant items on a fire risk assessment action list and open gaps behind door architraves.

In a village or hamlet like Ansty, 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.

We stand behind the work with a one-year guarantee.

Aftercare tips

Joint life depends on how it’s used and looked after. We suggest:

  • Check whether a sealant can be painted before decorating over it
  • Take pictures of fire stopping before ceilings or boxing go back
  • Allow for resealing whenever new services are run
  • Make resealing part of every contractor’s brief

Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot, so ask us which we used.

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

Work for landlords, hotels and businesses

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

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 fails, we can still redo it.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Commercial buildings in Ansty

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 work to the specification you’re given, installing the product to its tested details.

If you look after a church, hall or community building such as St John the Evangelist, older buildings that have had new heating or wiring often have service gaps worth checking. Managing a site like Warden Park School? Then fire-stopping around service openings should be restored whenever new services go in.

Do you need fire rated sealant in Ansty?

Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.

Common reasons people contact us are:

  • Fire seals that have cracked with movement
  • New service routes left unsealed after building work
  • Ordinary sealant used where a fire-rated product was needed
  • Open holes round services passing through fire walls

Rented homes near Haywards Heath station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.

Questions from Ansty

Do you cover Ansty for fire rated sealant?

Yes. Our work covers London and the South East, and Ansty is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.

Is Ansty within the area you cover?

Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Do you do fire sealant around door frames?

Yes, if the gap is within the product’s tested range. We seal the frame-to-wall gap, not the door itself.

Will we have a record of what was sealed?

Yes. Locations and products are written up when we finish. If you need pictures or a set layout, ask when you get a quote.

Which products do you use?

It depends on the joint: 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?

Intumescent describes a material that swells in heat. Many fire-rated sealants work this way, but not all.

How much does fire rated sealant cost in Ansty?

Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or send us an email and tell us what needs doing and where.

Do you offer different sealant colours?

Usually, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.

The process

All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. It normally takes a few hours for a handful of gaps, and longer for a whole building. For a village or hamlet like Ansty, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Before starting, we go through the specification or action list with you.
  2. Each gap is measured and its substrate and service noted.
  3. Any non-fire-rated filler is removed and the faces cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. We hand over a list of locations and products for your records.

Getting ready for the visit

Advice

What the job involves on each surface

Door frames

We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist, and we will say if we spot a problem with them.

Flats and HMOs

In flats and HMOs, the walls and floors between homes and common areas need sealing where services pass through. We seal the gaps your assessor has identified, flat by flat if needed.

What happens if it’s left?

Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. Where a wall is exposed, as many are in small places like Ansty, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we’ll go through it with you.
