Do you need fire rated sealant in Park Street?
In some buildings the gap was filled with the wrong thing in the first place: ordinary expanding foam, standard silicone or decorators’ caulk where a fire-rated seal was needed. It looks sealed, but it isn’t fire-rated.
If you can see any of these, it’s time to have the joints looked at:
- Unsealed gaps where pipes and cables go through a wall
- Joints picked up in a fire-stopping survey
- Standard silicone or caulk in a fire-stopping gap
- New service routes left unsealed after building work
If you look after a building such as Park Street Church of England Voluntary Aided Primary School, fire-stopping around service openings should be restored whenever new services go in.
Questions to ask before booking
- What preparation is included
- The length of the guarantee

- What insurance they hold
Fire rated sealant in Park Street
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on pipe & cable gaps, flats & HMOs and service penetrations, and common reasons people get in touch are gaps flagged on a fire risk assessment and door frames with gaps between frame and wall.
For a small place like Park Street, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of gaps, and longer for a whole building and we leave things clean and tidy. Somewhere like Park Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Before starting, we go through the specification or action list with you.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces 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.
Getting ready for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Let us know about stairs, lifts or work at height

Your questions about fire rated sealant in Park Street
Can you help a landlord with a rental near Park Street station?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover Park Street for fire rated sealant?
Yes, Park Street is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How long will you be here?
Most jobs take a few hours for a handful of gaps, and longer for a whole building. We will confirm how long when we quote.
Can you tell me which gaps need fire stopping?
No. We work from the specification you give us and install to the manufacturer’s details.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
How the job changes by surface
Linear gaps
Gaps along the top of partitions are easy to miss above a ceiling. We seal them along their full length leaving no stretch unsealed.
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Where a hole is bigger than the sealant’s tested range, it needs another approach, and we’ll tell you.
What fire rated sealant looks like in Park 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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
For landlords with property near Park Street station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. Community buildings like Church of the Holy Trinity are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Report cracked or damaged seals as soon as you notice them
- Check risers, ceiling voids and cupboards during building checks
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Keep the record of products and locations with your fire safety documents
Don’t add foam, filler or ordinary sealant over a fire seal. Repairs should use a matching fire-rated product. Ask us if you’re not sure which product was used.
An open gap is not only a fire issue: noise, draughts and even pests can come through too. Dealing with them early helps with all of these.

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It will not solve:
- Fire risk assessments, which need a qualified assessor
- Issuing a fire rating or certificate for a building
- Openings too large for sealant, which need batts, boards or another system
If in doubt, call 0345 464 0079 or email us and we will say what we think.

What affects the cost of fire rated sealant
There’s no set price list, because jobs vary so much. What we look at:
- Which sealant suits the joint
- Any mould that needs treating
- How many rooms, windows or areas are involved
- Whether the work is at height
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first.
