Brook Street: your questions answered
Do you cover Brook Street for fire rated sealant?
Yes. Our work covers London and the South East, and Brook Street is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
I let a flat near Haywards Heath station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
How long does the job take?
Most jobs take a few hours for a handful of gaps, and longer for a whole building. Your quote will say how long we expect yours to take.
Can I use normal mastic around a pipe through a fire wall?
No. Standard sealants aren’t made or tested to stop fire. If it’s been used, we remove it and use the right product.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
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, recording the locations and products.
Are you insured?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Do you carry out fire risk assessments?
No. That’s for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
Fire rated sealant in Brook Street
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. We work on flats & HMOs, door frames and linear gaps, and common reasons people get in touch are joints picked up in a fire-stopping survey and ordinary sealant used where a fire-rated product was needed.
In a village or hamlet like Brook Street, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Fire rated sealant in Brook Street: local notes
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, which is often where open fire-stopping gaps are first noticed. 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 Haywards Heath 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 Holy Trinity Church of England Primary School, service openings in fire-resisting walls need checking after any refurbishment.

How we quote for fire rated sealant
Call for a quick quote. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- How many areas need sealing
- The number and length of the joints
- Which sealant suits the joint
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before work begins.
Helping us quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Whether it has been sealed before
- Pictures of the joints, sent by email
- Where the job is, and your postcode
- The problem you’ve noticed
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
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. All the old material has to come out first.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Ask every contractor to reseal any fire stopping they disturb
- Look in service cupboards and ceiling voids from time to time
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Ask which product was used before you paint
Avoid covering a sealed gap with anything that is not part of the tested detail. Repairs should use a matching fire-rated product. We can tell you which product we used.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Sealing them early helps on every front.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Issuing a fire rating or certificate for a building
- Doors that aren’t fire doors in the first place
- Big openings where sealant alone isn’t the tested solution
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- Linear gaps
- Plasterboard & masonry
- Pipe & cable gaps
- Service penetrations
- Flats & HMOs
- Door frames
Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Having them sealed and recorded now gives you evidence that the item was dealt with. Where a wall is exposed, as many are in small places like Brook Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email and we’ll talk you through it.
