Fire rated sealant for homes and businesses in Shellwood Cross

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. Common call-outs are for gaps where walls meet ceilings or slabs and unsealed gaps around fire door frames, on pipe & cable gaps, service penetrations and door frames.

In a village or hamlet like Shellwood Cross, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.

Whatever the size of the job, it’s backed by our one-year guarantee.

What affects the cost of fire rated sealant

We don’t publish a price list. The quote depends on:

  • Any working-time requirements on site
  • How many areas need sealing
  • The product the joint needs
  • Whether old sealant or filler has to be cut out

We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or send us an email and we will talk you through it.

What to tell us for a quote

When you contact us, these details help:

  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that’s easy
  • How we’d reach the joints
  • How many joints, rooms or windows are involved

The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add pictures by email if you can.

What we cannot put right

To be straight with you, there are a few things sealant will not fix:

  • Fire risk assessments, which need a qualified assessor
  • Openings too large for sealant, which need batts, boards or another system
  • Walls or floors that weren’t built to resist fire

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

Joints and surfaces we work on

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

What we do, step by step

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Shellwood Cross 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. 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. 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

  • Try not to wet indoor joints just before the visit
  • For business premises, tell us about site rules or sign-in
  • Mention if the joints have been sealed before

Advice

Shellwood Cross: your questions answered

Is Shellwood Cross in your area for fire rated sealant?

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

I let a flat near Holmwood station. Can you help?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.

Where are you based?

We work from Crawley. Our applicators cover Shellwood Cross.

Is it messy?

We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.

How long will you be here?

That depends on the amount of work, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will give you a better idea when we quote.

Is the work guaranteed?

Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.

Can I choose the sealant colour?

We help you choose a colour that suits. The choice depends on the product the joint needs.

Do you hold any approvals?

Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

What we’re called out for in Shellwood Cross

Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.

People normally contact us after spotting something like this:

  • Open holes round services passing through fire walls
  • Seals cut through by electricians, plumbers or data installers
  • Old fire sealant that has split or come away
  • Open joints along the top of partitions

For landlords with property near Holmwood station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Questions to ask before you book

  • How the surfaces are prepared before sealing
  • What insurance they hold
  • Which colour the sealant will be
  • The length of the guarantee

Our hiring checklist

Different surfaces, different methods

Linear gaps

Linear gaps run along the head of walls, at floor edges and between panels. They’re sealed with a fire-rated sealant over backing where the detail calls for it.

Plasterboard walls

Service holes in plasterboard are often rough and oversized. Gaps that are too big for sealant alone need a different detail, and we will tell you.

Should I try it myself first?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Fire rated sealant in Shellwood Cross: local notes

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 look after a church, hall or community building such as Church of St Bartholomew, service openings in its walls need the right fire-rated sealant, as in any building.
