Why it’s worth doing now in Gushmere
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. Where a wall is exposed, as many are in small places like Gushmere, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.

Fire rated sealant for homes and businesses in Gushmere
Until it’s heated, intumescent sealant behaves like an ordinary sealant; 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. We are often asked to deal with door frames with gaps between frame and wall and gaps filled with a product that isn’t fire-rated, on flats & HMOs, plasterboard & masonry and pipe & cable gaps.
Work in a small place like Gushmere is planned ahead, journey included, so the job can fit around bookings, guests or opening times where possible.
Every job comes with our 12-month guarantee.

When it isn’t the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Assessing a building’s fire safety
- Construction that doesn’t provide fire resistance on its own
- Large holes that need a different fire-stopping system
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Do you cover Gushmere for fire rated sealant?
Yes, Gushmere is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is Gushmere within the area you cover?
Yes. Gushmere is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will the old sealant be removed?

Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one of the options. We use whichever the specification and tested details call for.
Do you seal gaps around fire door frames?
Yes. Gaps behind architraves are a common job for us. The door and its fittings are a separate job for a door specialist.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you work in flats, HMOs and commercial buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Tell us how the building is used and we’ll plan around it.
Quotes for fire rated sealant in Gushmere
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Working hours on commercial sites
- How much there is to do
- Whether the work is at height

A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Pictures of the joints, sent by email
- If someone has resealed it before
For a quick quote, get us on the phone, or send an email if you’d rather. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Flag any open gap you spot round a pipe or cable
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Check whether a sealant can be painted before decorating over it
- Allow for resealing whenever new services are run
Do not add foam, filler or ordinary sealant over a fire seal. If it needs repair, use the same type of product. Ask us if you’re not sure which product was used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
Fire rated sealant in Gushmere: local notes
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’re given, installing the product to its tested details.
Schools such as Selling Church of England Primary School are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices. If you look after a church, hall or community building such as Church of St Mary, older buildings that have had new heating or wiring often have service gaps worth checking.

Advice
Signs you need fire rated sealant in Gushmere
Sometimes the wrong product was used from the start: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It may look fine, but it is not a fire-rated seal.
Most people get in touch when they notice something like this:
- Open gaps behind door architraves
- Damaged fire sealant left by other trades
- Fire seals that have cracked with movement
- Linear gaps at the head of walls
Rented homes near Selling station change hands often, and new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
