Fire rated sealant in Micklefield Green

How we quote for fire rated sealant

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

  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove
  • Whether the work is at height
  • The number of rooms or windows

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

What to tell us for a quote

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

  • Any previous sealing or DIY work
  • Pictures of the joints, sent by email
  • The type of property
  • The rough size of the job

There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.

About our fire rated sealant in Micklefield Green

Ordinary silicone or decorators’ caulk in a fire-stopping gap is not a fire-rated seal. We cut out the wrong material and reseal with a fire-rated product tested for that kind of gap. If you are dealing with holes left by a change of layout and open holes round services passing through fire walls, we can help, whatever the surface.

In a village or hamlet like Micklefield Green, 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, so you’re covered after we’ve gone.

Can I do it myself?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Why deal with it now?

Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now means you can show the action was taken. Older cottages and farmhouses around Micklefield Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

Why us?

  • Quality sealants from Arbo and Everbuild
  • Any old sealant cut out fully, not covered over
  • A 12-month guarantee on all work
  • 20+ years of sealant experience

Honest limits

Before you book, it’s worth knowing the limits:

  • Big openings where sealant alone is not the tested solution
  • Sign-off of the building, which sits with building control or your assessor
  • Doors that aren’t fire doors in the first place

If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Surfaces we seal

  • Pipe & cable gaps
  • Linear gaps
  • Plasterboard & masonry

Micklefield Green: your questions answered

Will you come out to Micklefield Green?

Yes. Micklefield Green is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Do you cover Micklefield Green for fire rated sealant?

Yes, Micklefield Green is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.

What does intumescent mean?

An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all.

Can you seal over the old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

How much does fire rated sealant cost in Micklefield Green?

There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before work begins.

I rent my home. Can I book you?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

Will we have a record of what was sealed?

Yes. When the job is done, we give you the locations and products. If you need photos or a set layout, ask when you get a quote.

What should I tell you?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or email us.

Looking after it afterwards

Good habits help new joints last longer. A few tips:

  • Report cracked or damaged seals as soon as you notice them
  • Check whether a sealant can be painted before decorating over it
  • File the fire-stopping record where your assessor can find it
  • Keep photos of seals that will be hidden

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot, so ask us which we used.

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

Fire rated sealant around Micklefield Green

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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

Community buildings like Church of the Holy Cross are part of the picture too: gaps around pipes and cables are worth checking after any building work there. Rented homes near Chorleywood station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Common problems we fix in Micklefield Green

Much fire stopping is hidden: in ceiling voids, service risers and behind boxing. Because nobody sees it, gaps go unnoticed until an assessor or surveyor looks.

The most common problems we see are:

  • Linear gaps at the head of walls
  • Seals cut through by electricians, plumbers or data installers
  • Sealant items on a fire risk assessment action list
  • Standard silicone or caulk in a fire-stopping gap

Managing a site like Sarratt Church of England Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

The process

Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere as small as Micklefield Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  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. 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. We record the locations and products used for your records.

Before we arrive

  • Try not to wet indoor joints just before the visit
  • For business premises, tell us about site rules or sign-in
  • Tell us if parking is tricky
