Fire rated sealant in Pound Hill
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. We work on pipe & cable gaps, door frames and plasterboard & masonry, and common reasons people get in touch are linear gaps at the head of walls and gaps flagged on a fire risk assessment.
Commercial work around a smaller place like Pound Hill normally means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.
Whatever the size of the job, you get the same 12-month guarantee.

Fire rated sealant in Pound Hill: local notes
There are hotels and other places to stay in and around Pound Hill. Hotel work can be planned room by room, with out-of-hours working where needed. 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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For site and facilities teams at buildings such as Pound Hill Infant Academy, service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Three Bridges station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Photograph sealed gaps before they’re covered up
- Include hidden areas like risers in routine checks
- Tell trades working in the building that fire seals must be put back
- Never patch a fire seal with standard sealant
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
Any job that breaks through a wall or ceiling should include resealing. Catching it then saves a separate visit later.
What happens if it’s left?
Paying for fire stopping that has to be redone is a false economy. If the details weren’t followed, the seal may need redoing when the building is next checked. In a smaller place like Pound Hill, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before we start, so you know where you stand.

Honest limits
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Assessing a building’s fire safety
- Issuing a fire rating or certificate for a building
- Openings too large for sealant, which need batts, boards or another system
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before booking.
Joints and surfaces we work on
- Plasterboard & masonry
- Pipe & cable gaps
- Door frames
- Service penetrations
- Linear gaps
- Flats & HMOs
What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like Pound Hill, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Finally, we list where we worked and what we used, for your records.
Before we arrive
- Tell us if parking is tricky
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

Advice
What the job involves on each surface
Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth with backing where the detail needs it.
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before we start.
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
FAQs for Pound Hill
Do you cover smaller places like Pound Hill?
Yes, Pound Hill is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Three Bridges station?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How much does fire rated sealant cost in Pound Hill?
Every job is different, so each one gets its own quote. To get one, call 0345 464 0079 or send us an email and let us know what needs doing and where.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in.
Can you tell me how many minutes the seal will last?
That is not something we state or certify. The requirement comes from your assessor, designer or building control, and we fit a product whose tested details meet it.
What’s the difference between intumescent and fire-rated sealant?
An intumescent material expands when it’s heated. Many fire-rated sealants work this way, but not all and which one is used depends on the job.
When to call us in Pound Hill
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.
These are the problems we’re asked about most:
- Sealant items on a fire risk assessment action list
- Old fire sealant that has split or come away
- Unsealed gaps around fire door frames
- Open holes round services passing through fire walls
For buildings such as St Barnabas', older buildings that have had new heating or wiring often have service gaps worth checking.
