DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Fire rated sealant in Brookside
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we follow the tested detail for each one. If you have open joints along the top of partitions and holes left by a change of layout, we can help, on pipe & cable gaps, flats & HMOs and service penetrations alike.
If you have holiday lets, a converted barn used for business or a community building near Brookside, washroom and kitchen sealant and any fire-rated joints need the same attention as anywhere.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

Common questions in Brookside
Is Brookside in your area for fire rated sealant?
Yes. Our work covers London and the South East, and Brookside is part of that. You can phone 0345 464 0079 or send us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you help a landlord with a rental near Ascot station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Will there be a smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you work in occupied buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we will plan the work to suit.
How long does fire rated sealant take?
As a guide, most jobs take a few hours for a handful of gaps, and longer for a whole building. Bigger jobs take longer.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will tell you what we’re using.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
What happens if it’s left?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, and we work to the product details every time. Around Brookside, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Workplaces and buildings in Brookside
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.
Letting a property close to Ascot station? Then fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Schools such as Papplewick School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.

Honest limits
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Construction that does not provide fire resistance on its own
- Openings too large for sealant, which need batts, boards or another system
- Doors that aren’t fire doors in the first place
If you are not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

What affects the cost of fire rated sealant
There’s no set price list, because no two jobs are the same. What we look at:
- The number of rooms or windows
- Whether there’s mould to deal with
- Access and height
- Whether old sealant or filler has to be cut out
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.
Helping us quote
Before you ask for a quote, have a think about:
- How we’d reach the joints
- Pictures of the joints, sent by email
- If someone has resealed it before
- Where the job is, and your postcode
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, phone 0345 464 0079 or email us.
What we are called out for in Brookside
Lots of unsealed gaps appear long after the building was completed. Electricians, plumbers and data installers drill through walls and ceilings and the hole round the new service is not always sealed again.
Keep an eye out for any of the following:
- Sealant items on a fire risk assessment action list
- Fire stopping disturbed by later work
- Gaps left after a refit or conversion
- Unsealed gaps around fire door frames
If you look after a church, hall or community building such as Chapel of St Mary and St John, older buildings that have had new heating or wiring often have service gaps worth checking.
Questions to ask before you book
- How long to leave it before use
- Which sealant they’ll use, and why
- Is VAT in the price?
- Whether they’re fully insured
