Your questions about fire rated sealant in Margaretting

Is Margaretting in your area for fire rated sealant?

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

Can you help a landlord with a rental near Ingatestone station?

Yes, we work for letting agents and landlords. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Do you do fire sealant around door frames?

Yes, where the gap suits a sealant detail. We seal the frame-to-wall gap, not the door itself and we’ll tell you if we spot problems with the door.

Is it worth trying it myself?

It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Does someone need to be in?

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

What does intumescent mean?

Intumescent means it swells when heated, helping close the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.

What does fire rated sealant cost?

Size, access and the old material all affect the cost. Ask us for a quote.

Do you work in flats, HMOs and commercial buildings?

Yes. Occupied flats, HMOs, offices and schools are all fine and we plan access around the people using them. Out-of-hours work can be arranged.

Fire rated sealant in Margaretting

Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. Common call-outs are for joints picked up in a fire-stopping survey and new service routes left unsealed after building work, on pipe & cable gaps, flats & HMOs and plasterboard & masonry.

Somewhere as small as Margaretting, 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.

We stand behind the work with a 12-month guarantee.

The process

The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on how many gaps there are, and we explain the cure time before we leave. Somewhere like Margaretting needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
  2. We measure every gap and note what it’s in and what passes through.
  3. Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
  4. The specified fire-rated sealant goes in over any backing its detail requires.
  5. Every location is recorded with the product used for your files.

Preparing for the visit

  • Tell us about any previous sealing or DIY attempts
  • Tell us about any water getting in

Signs you need fire rated sealant in Margaretting

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.

Common reasons people contact us are:

  • Linear gaps at the head of walls
  • Open gaps behind door architraves
  • Gaps filled with a product that is not fire-rated
  • Old fire sealant that has split or come away

For buildings such as Church of St Margaret, older buildings that have had new heating or wiring often have service gaps worth checking.

Choosing a sealant specialist

DIY versus a professional finish

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

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.

How we quote for fire rated sealant

Your quote is based on your job. We take into account:

  • Any working-time requirements on site
  • How easy the joints are to reach
  • The number of rooms or windows
  • Which sealant suits the joint

The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Asking for a quote

When you call or email, these details help:

  • How we’d reach the joints
  • What’s wrong with the joints now
  • Where the property is
  • Any previous sealing or DIY work

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

Workplaces and buildings in Margaretting

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.

If you let a flat or house near Ingatestone station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Managing a site like Anglo European School? Then fire-stopping around service openings should be restored whenever new services go in.

Why deal with it now?

If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Around Margaretting, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What you get with us

  • Experience in homes, commercial sites and hotels
  • 180+ five-star Google reviews
  • Quality sealants from Arbo and Everbuild
  • Anti-fungal silicone where joints get wet

Looking after it afterwards

Good habits help new joints last longer. Our tips:

  • Keep the record of products and locations with your fire safety documents
  • Look in service cupboards and ceiling voids from time to time
  • Flag any open gap you spot round a pipe or cable
  • Take photos of fire stopping before ceilings or boxing go back

Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.

Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Honest limits

In fairness, there are a few things sealant won’t fix:

  • Construction that doesn’t provide fire resistance on its own
  • Sign-off of the building, which sits with building control or your assessor
  • Openings too large for sealant, which need batts, boards or another system

If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
