Fire stopping for businesses in Chestnut Street
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Our process
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For work around Chestnut Street, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First we go through the drawings, schedule or specification for the seals.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close
- Share the asbestos register for older buildings

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

How we handle fire stopping in Chestnut Street
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you are dealing with seals disturbed by maintenance and left open and old intumescent sealant that has split away, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Chestnut Street, that means joint design, primers and backing rod as standard.
Barn and farm-building conversions near places like Chestnut Street often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Maintenance after handover
Cleaning and maintenance staff play a part too. Share these points with them:
- Don’t let anyone top up a fire seal with the wrong product
- Keep product data and details in the fire safety file
- Arrange inspection before areas are covered up
- Ask the designer to confirm details early on refits
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, and the data sheet says which.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.
Fire-rated sealing for Chestnut Street buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Chestnut Street lies roughly 36 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.
Tenant changes at parks like Newington Enterprise Centre (to the north-west of Chestnut Street) bring new data and services, and openings through fire-resisting walls need the specified seal. Schools such as Borden Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Cost factors for service penetrations
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- The total length or number of joints
- How accessible the joints are
- How much existing material needs removing
- Location, for remote and island sites
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
- Specification clauses that apply
- Your programme or deadline
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Do you need fire stopping in Chestnut Street?
Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped, and the repair is often skipped.
Any of the following is a good reason to get the joints checked over:
- Fire sealant pulled out of the opening
- Open linear gaps along the top of fire-resisting walls
- Snag lists that include open service penetrations
- Openings left by services added after handover
Hospital estates such as Sittingbourne Memorial Hospital, 2.1 miles east of Chestnut Street, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Questions to ask before you book
- How the existing material will be dealt with
- Will RAMS and insurance details be available?
- The terms of the workmanship guarantee
- How the joint faces will be prepared and primed
Your questions answered
Can you seal penetrations in a hotel in Chestnut Street after a refit?
Yes, where fire-rated sealant is the specified product. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Could you schedule work at a campus like Sittingbourne College for the vacation?
Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
Will your applicators have CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Is the work guaranteed?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
Different surfaces, different methods
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.
Cables and cable bundles
Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and we tell you if the bundle exceeds what sealant covers.
Why act early in Chestnut Street
An unsealed opening affects more than fire safety: 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. Halls, stores and units around places like Chestnut Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
