When to bring in a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Fire stopping in Eton
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you’re dealing with improvised or mixed-product fire seals and non-fire-rated filler around services, we can help. One point of contact handles commercial sealant work in Eton from the first photographs to the final walk-round, for single jobs and planned programmes alike.
Smaller places such as Eton still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. For buildings around smaller places like Eton, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
What you get with us
- Clear, fixed quotes
- One number for every site we cover
- Old sealant cut out, never sealed over
- A Constructionline member, so easy to vet
Aftercare for building managers
Regular inspection catches problems early. In particular:
- Check with the data sheet before painting over fire sealant
- Foam or ordinary sealant is never a fire-seal repair
- Put resealing into every M&E and fit-out package
- Treat an open penetration as a priority repair
After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, which saves guesswork.
Surface by surface
Linear joints
Head-of-wall joints often have to absorb slab deflection. We use the product and backing the detail names for that movement.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.
Compartment walls and floors in Eton
For England, the fire stopping of penetrations is dealt with in Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. The 2 miles around Eton include three care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal.
Hotels such as Christopher Hotel (to the south of Eton) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Workshops and IT rooms at colleges like Windsor College, 1 mile south of Eton, are re-serviced often, leaving penetrations to seal. In a building such as Church of Saint John the Evangelist, any service penetration through a fire-resisting wall should be sealed to the specified detail.
Eton is about 1 mile north-east of Windsor, in Windsor and Maidenhead. Across the SL4 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Eton is one of 60 places we cover in Windsor and Maidenhead. Our Reading page has more on work in that area.
Work on service penetrations is covered throughout SL4, for business premises of every kind. Streets here include High Street, Eton Square and Common Lane. Access to Eton is via the A332 and B3022 among other routes, so getting applicators and materials to site is simple. Nearby places we also cover include Clewer (1 mile south-west), Eton Wick (1 mile west), Windsor (1 mile south-west), Boveney (2 miles west) and Dedworth (2 miles south-west) for service penetrations. A short drive away, we cover Maidenhead (6 miles west), Boyn Hill (6 miles west), Cookham (7 miles north-west), Furze Platt (6 miles north-west), Broomhall (7 miles south) and South Ascot (7 miles south).

Our process
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. If others near Eton need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Point out any areas we must not close
- Send any specification or drawings in advance

Advice
What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Writing the fire-stopping specification
- Large openings beyond what any sealant detail covers
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can phone 01277 525 020 or email us and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations

Your questions answered
Can you take on a job at a hospital such as Upton Hospital?
Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.
What happens to BS 476 references for fire stopping in Eton?
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.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
How do I request a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
What will the job cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Is the work guaranteed?
Yes. Workmanship is guaranteed for 12 months on every job.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
