Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Look in service cupboards and ceiling voids from time to time
- Report cracked or damaged seals as soon as you notice them
- Don’t paint over fire sealant until it has cured
- Store the list of sealed gaps with your building paperwork
Any fire seal that is cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
A flagged gap shouldn’t wait for the next assessment. Get it sealed and recorded so the item can be closed.
How we handle fire rated sealant in Blacknest
We often work from an action list drawn up by a fire risk assessor on buildings across Blacknest. If you share the list, we can quote for the gaps that need fire-rated sealant. Common call-outs are for ordinary sealant used where a fire-rated product was needed and damaged fire sealant left by other trades, across pipe & cable gaps, service penetrations and flats & HMOs.
For a small place like Blacknest, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
A one-year guarantee comes as standard.

What else we do in Blacknest
Common questions in Blacknest
Do you cover Blacknest for fire rated sealant?
Yes. We work across London and the South East, and Blacknest is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
Do you work for landlords with property near Bentley (Hampshire) station?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
What fire rating will the seal have?
We don’t certify fire stopping or quote ratings. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
Can you work in occupied buildings?
Yes. We work in flats, HMOs, schools, offices and other commercial buildings, including occupied ones. The order of work and access are planned with you.
Can you match the sealant colour?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or drop us an email.
Can you tell me which gaps need fire stopping?
No. That is for a fire risk assessor, designer or building control. Our job is applying the sealant to their specification.
What affects the cost of fire rated sealant
We do not publish a price list, because jobs vary so much. The quote depends on:
- The product the joint needs
- Working hours on commercial sites
- Mould in or behind the old joints
- The number of rooms or windows
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What we need to know
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- The address or postcode of the job
- The type of property
There’s no standard price list, because every job is different. Instead, we give you a clear price for your job. To get started, phone 0345 464 0079 or send us an email.
Why act early in Blacknest
Waiting for the next refit can leave a gap open for years. Sealing the gap now is a contained job on its own that does not depend on other work. In a small place like Blacknest, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- Full insurance on every job
- 20+ years of sealant experience
- Any old sealant cut out fully, not covered over
- Homes, businesses and hotels
Honest limits
In fairness, there are a few things sealant won’t fix:
- Openings too large for sealant, which need batts, boards or another system
- Fire doors that need new seals, closers or hardware
- Construction that doesn’t provide fire resistance on its own
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Surfaces we seal
- Flats & HMOs
- Pipe & cable gaps
- Linear gaps
- Plasterboard & masonry
- Door frames
- Service penetrations
Common problems we fix in Blacknest
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
The problems people normally mention when they call include:
- Joints picked up in a fire-stopping survey
- Gaps where walls meet ceilings or slabs
- Door frames with gaps between frame and wall
- Ordinary sealant used where a fire-rated product was needed
If you let a flat or house near Bentley (Hampshire) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
What to look for in a quote
- How the surfaces are prepared before sealing
- Whether all the old sealant comes out first
- What happens if the job turns out different
- Which sealant they’ll use, and why
Different surfaces, different methods
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required.
