Blindley Heath: your questions answered

Can you do fire rated sealant in Blindley Heath?

Yes. We work across London and the South East, and Blindley Heath is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.

Do you work for landlords with property near Godstone station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.

Can I choose the sealant colour?

We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

Is there a guarantee?

Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.

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

No. Ordinary silicone, caulk or foam is not tested as fire stopping. If it’s been used, we remove it and use the right product.

Can new sealant go over the old?

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

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in.

Can you tell me which gaps need fire stopping?

No. We follow the requirements from your assessor, designer or building control.

How we handle fire rated sealant in Blindley Heath

We do not assess buildings or decide what fire stopping is needed; your assessor, designer or building control sets that out. Our part is applying the specified sealant carefully, to the right depth and with the right backing. Common call-outs are for new service routes left unsealed after building work and old fire sealant that has split or come away, across door frames, pipe & cable gaps and plasterboard & masonry.

For a small place like Blindley Heath, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.

The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

How we quote for fire rated sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • Whether the work is at height
  • The product the joint needs
  • The number and length of the joints
  • Whether old sealant or filler has to be cut out

Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Asking for a quote

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • How we’d reach the joints
  • What the problem is, such as mould, gaps, leaks or cracking
  • How many joints, rooms or windows are involved
  • If someone has resealed it before

We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.

What sealant work can’t fix

We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:

  • Assessing a building’s fire safety
  • A wall that is not a fire-resisting element to begin with
  • Doors that are not fire doors in the first place

If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

What we seal

  • Plasterboard & masonry
  • Pipe & cable gaps
  • Door frames
  • Linear gaps
  • Flats & HMOs
  • Service penetrations

When to call us in Blindley Heath

Gaps also open up as buildings move: a seal that cracks or pulls away leaves a path for smoke. Knocks, maintenance and building work damage it further.

Keep an eye out for these signs:

  • Standard silicone or caulk in a fire-stopping gap
  • Unsealed gaps where pipes and cables go through a wall
  • Holes left by a change of layout
  • Open gaps behind door architraves

Rented homes near Godstone station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Our hiring checklist

Different surfaces, different methods

Door frames

Frame gaps are usually hidden behind the architrave. Where it’s open, we seal it to the product’s details for that gap size before the trim goes back.

Flats and HMOs

Flats and HMOs rely on fire separation between homes and the common parts. We work through the gaps on your assessment room by room.

How the visit works

There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are from start to finish. For a village or hamlet like Blindley Heath, the journey is planned in advance: let us know about lanes, gates and parking. 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. Old, damaged or unsuitable sealant is removed.
  3. Gaps are cleaned of dust and loose material.
  4. The fire-rated or intumescent sealant is applied and tooled to the tested detail.
  5. Locations and products are written up and any gaps unsuitable for sealant are flagged.

How to prepare

  • Let us know about earlier repairs to the joints
  • Keep pets and children clear of the area while we work
  • On commercial sites, let us know about site rules

Getting a quote

Getting a quote is simple: tell us what needs doing and where and its rough size. A few pictures by email make the job easier to understand, and we’ll take it from there.

Workplaces and buildings in Blindley Heath

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, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.

If you look after a church, hall or community building such as Church of St John the Evanglist, gaps around pipes and cables are worth checking after any building work there.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Flag any open gap you spot round a pipe or cable
  • Photograph sealed gaps before they’re covered up
  • Check whether a sealant can be painted before decorating over it
  • Include fire stopping when you schedule refits

Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some cannot.

If a fire risk assessment has flagged a gap, do not leave it for the next one. Get it sealed and recorded.
