Advice
How we handle fire stopping in Hampers Green
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on pipe penetrations, cable penetrations and small duct penetrations where the tested detail allows, and what we are called in for most is fire-rated sealant that has cracked or shrunk back and seals disturbed by maintenance and left open. One point of contact handles commercial sealant work in Hampers Green from the first photographs to the final walk-round, whether it’s one building or several.
A job near Hampers Green is usually planned around one visit, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Compartment walls and floors in Hampers Green
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. Central London is about 41 miles from Hampers Green. Office refits around the commuter belt bring new cabling through fire-resisting walls.
For a unit at a site such as Hampers Common Industrial Estate (less than half a mile south of Hampers Green), new power or data runs between office and warehouse can breach a compartment wall. In a hotel such as The Angel Hotel, 0.7 miles to the south of Hampers Green, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. For a school such as Petworth Cof E Primary School, penetration sealing fits best at the end of the summer works.

Keeping the joints sound
Cleaning and maintenance staff play a part too. Pass these on to them:
- Treat an open penetration as a priority repair
- Check risers and ceiling voids after each round of works
- Don’t let anyone top up a fire seal with the wrong product
- Agree the fire-stopping specification before services go in
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and installation follows the programme.
What the job involves on each surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, though larger ones usually call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
Why it’s worth doing now in Hampers Green
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these and the building feels the difference. Converted and older buildings near places like Hampers Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

Questions about Hampers Green
What does the BS 476 change mean for fire-rated sealant in Hampers Green?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you work on a hospital site such as Midhurst Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you work in Hampers Green?
Yes. We cover Hampers Green, within our coverage of Greater London, South East England and Scotland. To discuss a job, give us a call on 01277 525 020 or email us.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, which many sites require.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
Work for main contractors and building owners
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
