About our fire rated sealant in Birchanger

A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you are dealing with damaged fire sealant left by other trades and gaps flagged on a fire risk assessment, we can put it right.

If you have holiday lets, a converted barn used for business or a community building near Birchanger, the washrooms, kitchens and any fire-rated joints need the same care as a big site.

You get a one-year guarantee, the same in Birchanger as everywhere else we work.

The process

Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Birchanger needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Access to each area is agreed so the work can run in order.
  2. We take out any damaged or unsuitable sealant.
  3. Gaps are cleaned of dust and loose material.
  4. We apply and tool the sealant to the product’s tested detail.
  5. We record what was done and flag anything that needs a different system.

How to prepare

  • Mention any sign-in or site rules at work premises
  • Let us know about earlier repairs to the joints
  • Where the joints are inside, avoid wetting them before we arrive

What affects the quote in Birchanger

We quote each job individually. This is what makes a difference:

  • Whether there’s mould to deal with
  • The type of sealant required
  • Whether old sealant or filler has to be cut out
  • How much there is to do

Some things make a job bigger or smaller: 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.

Helping us quote

There’s no need for technical detail. It helps if you can tell us:

  • If it’s domestic, commercial or a hotel
  • Access, such as stairs, a lift or height
  • What’s wrong with the joints now
  • Whether it has been sealed before

We quote each job on its own, so start by telling us what you need. Simply ring 0345 464 0079 or email us and describe the job, and pictures are welcome.

Fire rated sealant in Birchanger: local notes

Birchanger has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. 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.

Managing a site like Birchwood High School? Then service openings in fire-resisting walls need checking after any refurbishment. Letting a property close to Stansted Mountfitchet station? Then any gap left by new services in shared walls should be closed with a fire-rated product. If you look after a church, hall or community building such as Church of St Mary, gaps around pipes and cables are worth checking after any building work there.

Aftercare tips

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Don’t fill fire-stopping gaps with ordinary foam or silicone
  • Allow for resealing whenever new services are run
  • Don’t paint over fire sealant until it has cured
  • Report cracked or damaged seals as soon as you notice them

Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole.

What we can’t put right

We’ll always be straight with you, so here’s what sealant can’t fix:

  • Deciding what fire stopping a building needs
  • Issuing a fire rating or certificate for a building
  • A wall that isn’t a fire-resisting element to begin with

Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before booking.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Different surfaces, different methods

Linear gaps

Some linear gaps have to cope with movement as well as fire. We choose a product and depth that suit the gap and the movement from the manufacturer’s details.

Masonry and concrete

Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it before the sealant goes in.

Common questions in Birchanger

Do you work for hotels and guest houses in Birchanger?

Yes. Hotel and guest-house work is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.

I let a flat near Stansted Mountfitchet station. Can you help?

Yes, we work for letting agents and landlords. Just call 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.

Can you quote for more than one area?

Yes, we can. Several rooms, windows or areas can go on one quote.

What sealant do you use?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.

Will there be a smell?

There can be a smell while the sealant cures, but it fades. Ventilation helps.

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

That is not something we state or certify. Your specification sets the requirement, and we apply a product tested for it.

Is it OK to seal over old sealant?

No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.

How do I get a quote for fire rated sealant in Birchanger?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.

Why act early in Birchanger

A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, so both the product and the method matter. Older cottages and farmhouses around Birchanger can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Why us?

  • Experience in homes, commercial sites and hotels
  • A 12-month guarantee on all work
  • Old sealant always removed completely
  • Anti-fungal silicone where joints get wet
