Fire stopping in Hempton, done properly
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. If you have seals disturbed by maintenance and left open and head-of-wall gaps with no fire seal, we can help, whatever the surface. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hempton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A job near Hempton is usually planned around one visit, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Why it’s worth doing now in Hempton
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 each detail can be checked as we go. For buildings around smaller places like Hempton, 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.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

How the quote is worked out
What shapes the price:
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
- Site requirements such as inductions and permits
- Phasing around occupants
The product called for affects the cost, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
What to include in your enquiry
A few photos plus some basic facts will normally do. Please tell us:
- Where the site is, with the postcode
- What the building is and how it’s used
- Any dates the work must fit around
- Rough lengths or quantities, or drawings if you have them
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, phone 01277 525 020 or send photos by email.

Common problems we fix in Hempton
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
Most enquiries start with one or more of the following:
- Expanding foam used as fire stopping
- Seals disturbed by maintenance and left open
- Openings left by services added after handover
- Penetration schedules that need working through
In a building such as Saint John the Evangelist, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Looking after the joints
Once the work is signed off, these steps help:
- Treat an open penetration as a priority repair
- Get seals inspected before ceilings and boxing close
- Ask the designer to confirm details early on refits
- Look above ceilings when tiles are lifted for other jobs
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.
Compartments and services around Hempton
Hempton lies roughly 63 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.
Hospital estates such as Horton General Hospital (to the north of Hempton) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. For a unit at a site such as Station Yard Industrial Estate (2.6 miles north-east of Hempton), new power or data runs between office and warehouse can breach a compartment wall.

On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it.

- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site

- Send any specification or drawings in advance
- Let building users know which areas are affected

Advice
Questions about Hempton
What happens to BS 476 references for fire stopping in Hempton?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Do you take on work at healthcare sites like Horton General Hospital?
Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Are you CHAS accredited and on Constructionline?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Is the work guaranteed?
Yes. Our workmanship is backed for 12 months.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Doing it in-house
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
