Fire rated sealant in Stansted Mountfitchet

Looking after it afterwards

To keep the joints looking good and working properly:

  • Don’t paint over fire sealant until it has cured
  • Keep the record of products and locations with your fire safety documents
  • Tell trades working in the building that fire seals must be put back
  • Keep general-purpose foam and caulk away from fire-stopping gaps

Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.

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

How we handle fire rated sealant in Stansted Mountfitchet

Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on. We work on plasterboard & masonry, service penetrations and linear gaps, and common reasons people get in touch are damaged fire sealant left by other trades and gaps flagged on a fire risk assessment.

If you run a pub, café, guest house or shop in or near Stansted Mountfitchet, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.

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

What affects the quote in Stansted Mountfitchet

You’ll get a clear quote before any work starts. It takes into account:

  • The number of rooms or windows
  • The product the joint needs
  • Whether the work is at height
  • The number and length of the joints

Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or email us and we will give you an honest view and a quote.

What to tell us when you ask for a quote:

  • Photos by email, if that’s easy

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

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 does not work out, we can still put it right.

What fire rated sealant looks like in Stansted Mountfitchet

Stansted Mountfitchet has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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.

Rented homes near Stansted Mountfitchet station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a building such as Magna Carta Primary Academy, gaps opened by contractors for new cabling are a common finding in schools and offices.

How the visit works

All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. For a job in Stansted Mountfitchet, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. We start with the survey or action list, checking the size and surfaces of every gap.
  2. Anything that is not fit for the job comes out, and the gap is cleaned.
  3. We put in whatever backing or fill the product detail specifies.
  4. The sealant goes in to the depth its detail sets, then it’s tooled off.
  5. We record the locations and products used for your records.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Let us know about parking restrictions
  • Keep pets and children clear of the area while we work

Related advice

What happens if it’s left?

Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Around Stansted Mountfitchet, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

What we are called out for in Stansted Mountfitchet

Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.

The most common problems we see are:

  • Cracked or shrunken fire-rated sealant
  • Gaps around pipes and cables through fire-resisting walls
  • Holes left by a change of layout
  • Gaps where walls meet ceilings or slabs

Community buildings like Church of St John the Evangelist are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.

Stansted Mountfitchet: your questions answered

Do you take on hotel work around Stansted Mountfitchet?

Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

Will you come out to Stansted Mountfitchet?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Will you leave a mess?

We keep the work tidy. We protect what’s around the joints.

What does intumescent mean?

Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one option among several. The specification and the tested detail decide which is used.

Do you provide details of the products used?

Yes. You get a list of where we worked and what we used.

Can ordinary silicone be used in a fire-stopping gap?

No. It might close the gap, but it is not a fire-rated seal. Use a product tested for that gap and service, or ask us to do it.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures.

Can I add another job to the visit?

Yes, and it often makes sense. Doing several areas at once is generally more efficient.
