Fire stopping in Donnington
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. A rating such as EI 60 only holds when the product is installed as it was tested. Reproducing the tested arrangement on site is the part we take care of. We work on small duct penetrations where the tested detail allows, cable penetrations and service gaps in risers, and the failures we’re asked to look at most are damaged fire seals in risers and voids and snag lists that include open service penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Donnington is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around Donnington, penetration and linear seals tend to be one-building jobs. Send the specification, drawings or photographs of the openings and we’ll quote to suit.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Service penetrations in Donnington buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail. The 2 miles around Donnington include seven care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.
Residences at universities like Oxford Brookes University Headington Campus (1.2 miles north of Donnington) have compartment walls that must be resealed whenever services change. For a unit at a site such as Templars Shopping Park, 0.8 miles to the south-east of Donnington, any new service through a fire-resisting wall should be sealed to the tested detail. Workshops and IT rooms at colleges like Oxford Sixth Form College, 1.3 miles north-west of Donnington, are re-serviced often, leaving penetrations to seal.
Donnington is about 1 mile south of Oxford, in Oxfordshire. Anywhere in OX4, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. 423 places across Oxfordshire fall within our area, including Donnington.

Diagnose, treat, sign off
Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If neighbouring businesses or buildings around Donnington need work too, visits can be combined. Mention the building’s opening times and we’ll work within them.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
- For older buildings, check the asbestos register before work

Donnington: questions and answers
Is a hospital such as Warneford Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
What happens to BS 476 references for fire stopping in Donnington?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
Is Donnington in your area?
Yes. Donnington falls within our area, and you can ring 01277 525 020 or email the details over to get started.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
Why deal with it now?
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. In a smaller place such as Donnington, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

- A Constructionline member, so easy to vet
- 12-month guarantee on workmanship
- CHAS accredited
What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Deciding what a wall or floor needs, which belongs to the designer
- Approving the work on behalf of building control
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can call 01277 525 020 or email us and we will tell you honestly before you book.
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

What affects the price in Donnington
Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:
- How much there is to seal
- Whether old sealant has to be cut out first
- Induction, permit and paperwork requirements
- Distance, for remote addresses
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
Details that help us quote
We can often quote from photos and a few details. Please tell us:
- The type of building and who uses it
- Whether an asbestos survey exists
- When you need the work done
- Where the site is, with the postcode
Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or email us.
How the job changes by surface
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we will say if that applies.
Metal pipes
Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
