How we handle fire stopping in Ashwell
Facilities managers in Ashwell often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. We work on linear gaps at wall heads, small duct penetrations where the tested detail allows and service gaps in risers, and the failures we are asked to look at most are hidden openings found during inspections and fire sealant pulled out of the opening. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Ashwell it comes down to the same thing: the right product in a properly prepared joint.
In places the size of Ashwell, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
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.

Fire stopping around Ashwell: what changes locally
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. Either way, we install the specified product to its tested detail. Central London is about 37 miles from Ashwell. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
For a building such as St Mary's Church, new heating or data runs are the usual reason penetrations need sealing. Hospital estates such as Fairfield Hospital, 4.8 miles to the south-west of Ashwell, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Ashwell is about 5 miles north-east of Letchworth, in Hertfordshire. Anywhere in SG7, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Ashwell is one of 371 places in Hertfordshire on our list for service penetrations. We also cover London, some 37 miles away.
Postcode districts covered here: SG7. Among the streets we cover are High Street, Station Road and Alms Lane. We also cover Ashwell End (1 mile west), Bury End (2 miles west), Newnham (2 miles south-west), Caldecote (2 miles west) and Hinxworth (2 miles west). Bigger towns within reach include Stevenage (9 miles south), Hitchin (8 miles south-west), Letchworth (5 miles south-west), Letchworth Garden City (5 miles south-west), Stotfold (4 miles south-west) and Baldock (4 miles south).

Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Several jobs near Ashwell can be grouped on one trip. Mention the building’s opening times and we will work within them.
- We read the specification, drawings or penetration schedule you send.
- 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.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Send your site hours and access windows
- Warn occupants and staff about the work
- Arrange parking or a loading space

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.
Advice
Questions we’re asked in Ashwell
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Ashwell?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
Is a smaller place like Ashwell outside your area?
No. Places such as Ashwell are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can staff carry on working while you are here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Cost factors for service penetrations
To price the job, we consider:
- How much there is to seal
- How accessible the joints are
- Phasing around occupants
- Backing rod, priming and other preparation
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Access details, including height
- Drawings or a marked-up plan, if available
- A wide shot and a close-up of the area
- Whether an asbestos survey exists
Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, ring 01277 525 020 or email us.
Do you need fire stopping in Ashwell?
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Over a few years of fit-outs, a wall can collect a lot of these.
Any of the following is a good reason to get the joints checked over:
- Unsealed joints where partitions meet the slab
- Seals that don’t match their tested detail
- Openings found when ceilings come down for a refit
- Fire sealant pulled out of the opening
In a school such as Ashwell Primary School, fire-rated sealant goes in around service penetrations where it is specified.

What else we do in Ashwell
What sealant work can’t fix
We check first that sealant really is the fix. It isn’t the answer for:
- Construction that lacks the fire resistance the seal relies on
- Deciding what a wall or floor needs, which belongs to the designer
- Approving the work on behalf of building control
If in doubt, give us a call on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Pipe penetrations
- Cable penetrations
- Small duct penetrations where the tested detail allows
Leave it or put it right?
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. Small buildings around Ashwell suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
