How we quote for fire rated sealant
There’s no set price list, because jobs vary so much. What we look at:
- The number of rooms or windows
- Whether the work is at height
- The amount of work
- Any mould that needs treating
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
What to tell us for a quote
When you contact us, it’s useful to know:
- Pictures of the joints, sent by email
- Any previous sealing or DIY work
- How we’d reach the joints
- Where the job is, and your postcode
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
Fire rated sealant for homes and businesses in Charlton-in-Dover
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have fire stopping disturbed by later work and holes left by a change of layout, we can help, whatever the surface.
If you run a pub, café, guest house or shop in or near Charlton-in-Dover, the washrooms and kitchen need the same attention as a big site, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
There’s a 12-month guarantee on every job, whatever its size.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Charlton-in-Dover: your questions answered
Do you work for hotels and guest houses in Charlton-in-Dover?
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.
I let a flat near Dover Priory station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Where are you based?
Mr Mastic is based in Crawley. We cover Charlton-in-Dover and the rest of Kent, along with the rest of our area.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you need fire rated sealant in Charlton-in-Dover?
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk in a place that needed a tested fire seal. It looks sealed, but it is not fire-rated.
Any of these means the joints need attention:
- Fire stopping disturbed by later work
- Unsealed gaps where pipes and cables go through a wall
- Standard silicone or caulk in a fire-stopping gap
- Linear gaps at the head of walls
For buildings such as Church of St Peter and St Paul, older buildings that have had new heating or wiring often have service gaps worth checking.

Fire rated sealant in Charlton-in-Dover: local notes
For seaside hotels, guest houses and holiday lets around Charlton-in-Dover, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 let a flat or house near Dover Priory station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. If you look after a building such as Charlton Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Landlord and commercial work in Charlton-in-Dover
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will quote.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Include fire stopping when you schedule refits
- Flag any open gap you spot round a pipe or cable
- Check risers, ceiling voids and cupboards during building checks
- Never patch a fire seal with standard sealant
Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you are not sure which product was used.
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 it’s worth doing now in Charlton-in-Dover
Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. Homes in smaller places like Charlton-in-Dover can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Commercial jobs are quoted on the same basis as homes: 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.
