About our fire rated sealant in Bellingham

Fire-rated sealant closes the gaps around pipes, cables and frames where they pass through a fire-resisting wall or floor. Each gap is sealed to the product maker’s tested detail for its size and substrate, with a record of the products and locations if you need one. We work on pipe & cable gaps, door frames and flats & HMOs, and common reasons people get in touch are unsealed gaps where pipes and cables go through a wall and door frames with gaps between frame and wall.

London’s offices, shops, hotels, student accommodation and blocks of flats all have joints to look after, whether that is washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Bellingham can’t close.

You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

The process

We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. In a London area like Bellingham, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.

  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. Any non-fire-rated filler is removed and the faces cleaned.
  4. We fit backing where needed and apply the fire-rated sealant to depth.
  5. We hand over a list of locations and products.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Move anything stored near the joints
  • Plan for the work area to be out of bounds to pets and children

Advice

Aftercare tips

To keep the joints looking good and working properly:

  • Look in service cupboards and ceiling voids from time to time
  • Report cracked or damaged seals as soon as you notice them
  • Check whether a sealant can be painted before decorating over it
  • Don’t fill fire-stopping gaps with ordinary foam or silicone

Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.

It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.

Workplaces and buildings in Bellingham

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. Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange.

As a London address, Bellingham can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Elfrida Primary School, service openings in fire-resisting walls need checking after any refurbishment.

DIY sealant or a professional job?

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Bellingham questions

Can parking be tricky for a visit in Bellingham?

Parking in Bellingham, as in most of London, takes a little planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

Do you work for landlords with property near Bellingham station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.

Can you match the sealant colour?

Generally, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.

Can you tell me which gaps need fire stopping?

No, we don’t assess buildings. When your assessor or designer has set out what’s needed, we will quote for the sealant work on it.

Where do you work from?

Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.

Do you take on fire stopping in schools and offices?

Yes, in flats, HMOs, schools, offices and other buildings, occupied or empty. Let us know the building’s hours and we’ll plan the work to suit.

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

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

Will we have a record of what was sealed?

Yes. We note each location and the product that went in, so you have it on file.

What affects the cost of fire rated sealant

We do not publish a price list. The quote depends on:

  • The number and length of the joints
  • The number of rooms or windows
  • Whether there’s mould to deal with
  • Access and height

Doing several joints on one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.

Helping us quote

To help us quote quickly, please include:

  • Any access issues, like height or stairs
  • The problem you’ve noticed
  • Roughly how big the job is
  • Where the job is, and your postcode

Every job is quoted individually, so start by telling us what you need. Just phone 0345 464 0079 or drop us an email with the details, and pictures are welcome.

Why it’s worth doing now in Bellingham

Leaving a gap until a refurbishment comes round can mean years with it open. Sealing the gap now is a contained job on its own that doesn’t depend on other work. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Bellingham.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Why us?

  • 12-month guarantee on every job
  • Trusted Arbo and Everbuild sealants
  • We never seal over old sealant
  • Anti-fungal silicone where joints get wet

What we are called out for in Bellingham

Sealant applied too thin, without the backing its detail needs, or onto dust will not perform as it was tested. We see plenty of fire stopping that was hurried.

These are the problems we are asked about most:

  • Holes left by a change of layout
  • Cracked or shrunken fire-rated sealant
  • Linear gaps at the head of walls
  • Ordinary sealant used where a fire-rated product was needed

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

What your quote should include

  • Whether you can choose the colour
  • Is the old sealant removed completely?
  • What insurance they hold
  • Who turns up on the day
