Fire stopping for commercial buildings in Hammer Bottom
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. The enquiries we see most involve old intumescent sealant that has split away and expanding foam used as fire stopping, on service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations. A single leaking joint is often how a building in Hammer Bottom first comes to us: we look at the rest while we are there and tell you what we find.
Around smaller places like Hammer Bottom, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Surface by surface
Small ducts
Some fire-rated sealant details cover small ducts. Larger or fire-rated ductwork normally needs a different solution set by the designer, and we will say if that applies.
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, with backing added if the detail requires it.
How a job runs
When we get to site, 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, with the work itself typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. Jobs in and around smaller places like Hammer Bottom are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Clear stock, furniture or equipment away from the joints
- Point out any areas we must not close

Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Treat an open penetration as a priority repair
- Get seals inspected before ceilings and boxing close
- Brief every trade that openings they make must be sealed
- Foam or ordinary sealant is never a fire-seal repair
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open.
Cost factors for service penetrations
A fixed quote reflects the actual work. It allows for:
- How much existing material needs removing
- Specialist products, such as fire-rated or hygienic sealants
- Working within restricted access windows
- Location, for remote and island sites
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
What we need to price the job
For an accurate fixed quote, we need a clear picture of the site. Useful things to include:
- Whether the building will be occupied during the work
- A wide shot and a close-up of the area
- The site address and postcode
- The product your specification calls for
For a fixed quote, speak to us on 01277 525 020 or email the details over. You can also send details through our quote form.
Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Fire stopping in Hammer Bottom: the local picture
The 2 miles around Hammer Bottom include three care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. What we install is set by the specification, and it goes in to the tested detail.
For a building such as The Parish Church of St Peter, new heating or data runs are the usual reason penetrations need sealing. For a school such as Woolmer Hill School, penetration sealing fits best at the end of the summer works. On a hospital site such as Holy Cross Hospital, which lies east of Hammer Bottom, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

What else we do in Hammer Bottom
Your questions answered
Is Hammer Bottom too far out for you?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you work in occupied care homes around Hammer Bottom?
Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.
Is it fine to apply new sealant on top of old?
No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
Is fire stopping in Scotland covered by different guidance?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, with proprietary products tested for the end use.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will you sign off the seals for us?
No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. Our part is fitting the specified product to its tested detail.
