Fire rated sealant in South Malling, done properly
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. We seal them with a product tested for that kind of gap. Common call-outs are for door frames with gaps between frame and wall and unsealed gaps where pipes and cables go through a wall, on linear gaps, flats & HMOs and pipe & cable gaps.
If you run a pub, café, guest house or shop in or near South Malling, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Whatever the size of the job, it’s backed by our one-year guarantee.

What fire rated sealant looks like in South Malling
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details. South Malling has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
If you let a flat or house near Lewes station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as South Malling CofE Primary and Nursery School, service openings in fire-resisting walls need checking after any refurbishment.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Report cracked or damaged seals as soon as you notice them
- Keep pictures of seals that will be hidden
- Store the list of sealed gaps with your building paperwork
- Tell trades working in the building that fire seals must be put back
Don’t drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
An open gap isn’t only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.
Why deal with it now?
A quick fill with any sealant to hand isn’t fire stopping. Fire-rated products are tested in set gap sizes, depths and substrates, which is why we match the product and the method to each gap. Around South Malling, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is normally more efficient than separate visits. We’ll give you a clear price for the lot.

DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
What happens on the day
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take anything from a few hours to several days, depending on how many gaps there are. For a job in South Malling, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
How to prepare
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

Your questions about fire rated sealant in South Malling
Do you work for landlords with property near Lewes station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you take on hotel work around South Malling?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
Where is Mr Mastic based?
Our base is Crawley. We work across South East England, London and Scotland.
Is standard sealant good enough for a fire gap?
No. It might close the gap, but it isn’t a fire-rated seal. A tested fire-rated product is needed, or ask us to do it.
Do you provide details of the products used?
Yes. You get a list of where we worked and what we used to keep with your fire safety documents.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is intumescent sealant the same as fire-rated sealant?
An intumescent sealant expands when it gets hot. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Can I choose the sealant colour?
Normally, yes. White, clear and grey are common, and other colours are available for many products, and we will agree it with you first.
When to call us in South Malling
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.
It’s worth asking for a quote if you see:
- Open joints along the top of partitions
- Holes left by a change of layout
- Open holes round services passing through fire walls
- Joints picked up in a fire-stopping survey
For buildings such as Church of St Michael, service openings in its walls need the right fire-rated sealant, as in any building.
