Fire stopping in Plastow Green, done properly
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. Site teams most often ask us about old intumescent sealant that has split away and hidden openings found during inspections, across joints between fire-resisting walls and floors, pipe penetrations and service gaps in risers. For commercial sealant work in Plastow Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A job near Plastow Green is normally planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Doing it in-house
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Smaller jobs around Plastow Green can be grouped with others nearby. A fixed quote is given before anything starts.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:
- Approving the work on behalf of building control
- Construction that lacks the fire resistance the seal relies on
- Openings that need collars, wraps, batts or boards rather than sealant
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think.
Surfaces we seal
- Linear gaps at wall heads
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
Your questions answered
Is a hospital such as West Berkshire Community Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
How does the move away from BS 476 affect penetration seals in Plastow 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. Our part doesn’t change: the specified product, to its tested detail.
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.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or email the details over. Include photographs or drawings if you have them.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Will you come and look before quoting?
That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.

What else we do in Plastow Green
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Arrange inspection before areas are covered up
- Treat an open penetration as a priority repair
- Keep general-purpose fillers away from compartment walls
- Check with the data sheet before painting over fire sealant
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Why act early in Plastow Green
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Older rural buildings around Plastow Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Why us?
- Joints cleaned back to sound surfaces
- Over 20 years of commercial sealing
- One contact handling all your sites
- 12 months’ guarantee on every job
Fire stopping in Plastow Green: the local picture
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Central London is about 50 miles from Plastow Green. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.
In a building such as Church of St Paul, any service penetration through a fire-resisting wall should be sealed to the specified detail. Tenant changes at parks like Scion Business Park (to the east of Plastow Green) bring new data and services, and openings through fire-resisting walls need the specified seal. For a school such as Cheam School, penetration sealing fits best at the end of the summer works.

Surface by surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness first.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
