On site: what to expect
Occupied buildings need a little choreography. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Holton St Mary, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Tell staff and tenants when we’ll be in
- Tell us your opening times and when work is allowed
- Send any specification or drawings in advance

Advice
Fire stopping in Holton St Mary
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on small duct penetrations where the tested detail allows, service gaps in risers and linear gaps at wall heads, and the usual reasons a site gets in touch are seals disturbed by maintenance and left open and expanding foam used as fire stopping. For commercial sealant work in Holton St Mary, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
A job near Holton St Mary is normally planned around one visit, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.

What happens if it’s left?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. For buildings around smaller places like Holton St Mary, 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.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Keeping the joints sound
Once the work is signed off, these steps help:
- Settle who seals which penetrations at the start of a project
- Flag new cables with no seal around them
- Foam or ordinary sealant is never a fire-seal repair
- Ask which product is in place before decorating
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
Honest limits
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Signing off or certifying a building’s fire stopping
- Plastic pipes whose detail calls for a collar or wrap
- Deciding what a wall or floor needs, which belongs to the designer
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.
Surfaces we seal
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
Compartment walls and floors in Holton St Mary
Approved Document B is the English guidance that covers fire stopping around 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. Either way, we install the specified product to its tested detail. Central London is about 58 miles from Holton St Mary. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
In a building such as Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail. In a school such as East Bergholt High School, fire-rated sealant goes in around service penetrations where it is specified.

How the quote is worked out
The price varies from site to site. It mainly depends on:
- The site’s rules and procedures
- The product specified
- Quantities, in metres or numbers
- Phasing around occupants
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.
Before you send an enquiry
However big the job, these details speed things up:
- Whether the building will be occupied during the work
- Rough lengths or quantities, or drawings if you have them
- Where the site is, with the postcode
- How the joints are reached, and at what height
Need a figure for a tender or a budget? We’ll quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or email the details over.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Your questions answered
How does the move away from BS 476 affect penetration seals in Holton St Mary?

Can you produce the fire-stopping design for a job in Holton St Mary?
No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.

Yes. Our applicators hold CSCS cards.
