How we quote for fire rated sealant
You’ll get a clear quote before work begins. It’s based on:
- Working hours on commercial sites
- The product the joint needs
- Any mould that needs treating
- Access and height
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Helping us quote
There’s no need for technical detail. Just tell us:
- Pictures of the joints, sent by email
- Where the property is
- How we’d reach the joints
- Roughly how big the job is
Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.
How we handle fire rated sealant in Mill Street
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. We are often asked to deal with fire stopping disturbed by later work and gaps left after a refit or conversion, across service penetrations, linear gaps and pipe & cable gaps.
If you have holiday lets, a converted barn used for business or a community building near Mill Street, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
You get a 12-month guarantee, the same in Mill Street as everywhere else we work.

Your questions about fire rated sealant in Mill Street
Is fire rated sealant in Mill Street guaranteed?
All our work, in Mill Street and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Can you do fire rated sealant in Mill Street?
Yes. Our work covers London and the South East, and Mill Street is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do you have insurance?
Yes. We’re fully insured for every job we do.
Do you provide details of the products used?
Yes. You get a list of where we worked and what we used for your files.
Is intumescent sealant the same as fire-rated sealant?
Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; the right one depends on the gap and what passes through it.
Will there be a smell?
There can be a smell while the sealant cures. Ventilation helps.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
How the job changes by surface
Masonry and concrete
Holes through concrete and block are rarely neat. We check the gap size around the service against the product’s tested range.
Door frames
We deal with the gap around the frame, not the door. The door leaf, its seals and closer need a door specialist.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Look in service cupboards and ceiling voids from time to time
- Keep the record of products and locations with your fire safety documents
- Tell trades working in the building that fire seals must be put back
- Report cracked or damaged seals as soon as you notice them
Leave the sealant to cure fully before painting near it. Not every fire-rated sealant takes paint, so ask us which we used.
Open gaps do not only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
What happens if it’s left?
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. Where a wall is exposed, as many are in small places like Mill Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

When it is not the sealant
In fairness, there are a few things sealant will not fix:
- Construction that doesn’t provide fire resistance on its own
- Big openings where sealant alone isn’t the tested solution
- Certifying a building or signing off its fire safety

Commercial buildings in Mill Street
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For site and facilities teams at buildings such as Stoke-by-Nayland Church of England Primary School, gaps opened by contractors for new cabling are a common finding in schools and offices.

Advice
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
