Fire rated sealant for East End Green homes and businesses

Fire rated sealant in East End Green

Bigger jobs can be worked through in stages, flat by flat or floor by floor. That record is useful for your files and for whoever looks at the building next. We work on linear gaps, service penetrations and plasterboard & masonry, and people most often call us about cracked or shrunken fire-rated sealant and seals cut through by electricians, plumbers or data installers.

Somewhere as small as East End Green, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Landlord and commercial work in East End Green

Letting agents often deal with us directly. Tell us the address, the job and how access works.

Housing providers, facilities teams and property managers book us too in East End Green and across Hertfordshire. We can quote a run of properties together, and we’re fully insured.

Different surfaces, different methods

Flats and HMOs

Conversions usually leave a mix of old and new service holes. We seal the ones on your specification with a tested product and the locations noted.

Service penetrations

Wherever a service goes through a fire-resisting wall or floor, there’s a gap around it. The sealant is chosen for what passes through and how wide the gap is.

Your questions about fire rated sealant in East End Green

I let a flat near Hertford North station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.

Can you do fire rated sealant in East End Green?

Yes, East End Green is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job.

How long does fire rated sealant take?

A typical job takes a few hours for a handful of gaps, and longer for a whole building. Your quote will say how long we expect yours to take.

Is intumescent sealant the same as fire-rated sealant?

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

Is there any odour?

Possibly a little. It fades as the sealant cures.

Can you give us a record of the work?

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

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

We don’t certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and list the locations and products for you.

Can you tell me which gaps need fire stopping?

No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.

What happens on the day

Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like East End Green needs a little journey planning: 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. We start with the survey or action list, checking the size and surfaces of every gap.
  2. We remove any old or unsuitable filler and clean the gap.
  3. Where the tested detail needs backing or fill, we fit it.
  4. Fire-rated or intumescent sealant is applied to the right depth and tooled.
  5. Finally, we list where we worked and what we used, for your records.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • Tell us if parking is tricky
  • On commercial sites, let us know about site rules

How to get a quote

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.

Advice

What affects the cost of fire rated sealant

The price is agreed before any work begins. It’s based on:

  • Whether old sealant or filler has to be cut out
  • Whether there’s mould to deal with
  • Whether the work is at height
  • Working hours on commercial sites

What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

What to tell us for a quote

Before you ask for a quote, have a think about:

  • The rough size of the job
  • How we’d reach the joints
  • If it’s domestic, commercial or a hotel
  • If someone has resealed it before

Need a quote? Please call 0345 464 0079 or drop us an email with a few details. We will explain what we’d do and give you a clear quote before work begins.

Keeping the joints in good condition

So the new joints stay in good condition:

  • Report cracked or damaged seals as soon as you notice them
  • Tell trades working in the building that fire seals must be put back
  • Don’t paint over fire sealant until it has cured
  • Look in service cupboards and ceiling voids from time to time

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

An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.

What fire rated sealant looks like in East End Green

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.

For landlords with property near Hertford North station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Hertingfordbury Cowper Primary School, service openings in fire-resisting walls need checking after any refurbishment. Community buildings like St John's Church are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Why it’s worth doing now in East End Green

An open gap in a fire-resisting wall is a route for smoke and fire. Sealing it properly restores what the wall was there to do, and the work involved is often modest. Where a wall is exposed, as many are in small places like East End Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

When it is not the sealant

We will not take on work that won’t last, so these are the limits:

  • A wall that is not a fire-resisting element to begin with
  • Issuing a fire rating or certificate for a building
  • Big openings where sealant alone is not the tested solution
