About our fire rated sealant in Whitesmith
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. If you have fire stopping disturbed by later work and new service routes left unsealed after building work, we can help.
In a village or hamlet like Whitesmith, 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.
Every job is covered by our 12-month guarantee, wherever you are in East Sussex.

How we quote for fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of rooms or windows
- Whether there’s mould to deal with
- Any working-time requirements on site
- The type of sealant required
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. We take all of that into account in your quote.
Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- Whether it’s a home or a business
- If someone has resealed it before
- Where the property is
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details.

What we do, step by step
On the day, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Whitesmith needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used for your files.

Questions from Whitesmith
Can you help a landlord with a rental near Berwick (Sussex) station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Is Whitesmith in your area for fire rated sealant?
Yes, Whitesmith is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Are you fully insured?
Yes. We’re fully insured.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated sealant covers any sealant tested for use in fire stopping. Intumescent ones swell in heat, and they’re one of the options. The specification and the tested detail decide which is used.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Why act early in Whitesmith
If an assessor has flagged gaps, it makes sense to close them before the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Around Whitesmith, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

Flats and HMOs

Fire rated sealant around Whitesmith

Managing a site like Chiddingly Primary School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.

Aftercare tips
Looking after new joints is easy, and it makes a real difference:
- Ask every contractor to reseal any fire stopping they disturb
- Store the list of sealed gaps with your building paperwork
- Report cracked or damaged seals as soon as you notice them
- Look in service cupboards and ceiling voids from time to time
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record.
