Fire-rated sealant in Dorking, Surrey
Our applicators work in Dorking on intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Standard silicone or caulk in a fire-stopping gap
- Fire seals that have cracked with movement
- New service routes left unsealed after building work
Fire rated sealant for homes and businesses in Dorking
Filling a fire-stopping gap with standard silicone or caulk does not make it fire-rated. Anything unsuitable comes out first and reseal with a fire-rated product tested for that kind of gap. If you’re dealing with joints picked up in a fire-stopping survey and unsealed gaps where pipes and cables go through a wall, we can put it right, whatever the surface.
In a town like Dorking, commercial work can mean offices, shops, schools, surgeries or small business units. Each has washrooms, kitchens and service openings through walls that need the right sealant.
There’s a 12-month guarantee on every job, whatever its size.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. 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.

Dorking: your questions answered
Is Dorking in your area for fire rated sealant?
Yes, Dorking is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Dorking Deepdene station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Can you tell me how many minutes the seal will last?
That is not something we state or certify. Your specification sets the requirement, and we fit a product whose tested details meet it.
Is intumescent sealant the same as fire-rated sealant?
Intumescent describes a material that swells in heat. Intumescent sealants are a type of fire-rated sealant and which one is used depends on the job.
Can I use normal mastic around a pipe through a fire wall?
No. A gap that needs fire stopping needs a tested fire-rated product, installed to its details.
Do you provide details of the products used?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
Can you tell me which gaps need fire stopping?
No. We follow the requirements from your assessor, designer or building control, and apply each product to its tested details.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Different surfaces, different methods
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes aren’t treated the same. We follow the manufacturer’s tested detail for each and we flag any that need another system.
Masonry and concrete
Masonry is dusty and porous, so preparation matters. We brush and vacuum the gap and use backing where the detail needs it.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Allow for resealing whenever new services are run
- Look in service cupboards and ceiling voids from time to time
- Keep pictures of seals that will be hidden
- Store the list of sealed gaps with your building paperwork
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we 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.
Landlords, agents and businesses in Dorking
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Landlords and agents in Dorking can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Big openings where sealant alone isn’t the tested solution
- Sign-off of the building, which sits with building control or your assessor
- Doors that aren’t fire doors in the first place
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Linear gaps
- Door frames
- Service penetrations
- Flats & HMOs
- Pipe & cable gaps
- Plasterboard & masonry
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are, and the area is left clean. In Dorking, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Unsuitable material such as ordinary foam or silicone is cut out and the gap cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
Preparing for the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
- Where the joints are inside, avoid wetting them before we arrive

What fire rated sealant looks like in Dorking
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. Dorking has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
For site and facilities teams at buildings such as St Paul's CofE (Aided) Primary School, service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Dorking Deepdene station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of St Paul, service openings in its walls need the right fire-rated sealant, as in any building.
