Fire stopping in Stotfold Common, done properly
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance in Stotfold Common and nearby. If you have service penetrations left open after M&E works and improvised or mixed-product fire seals, 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: on jobs in Stotfold Common, preparation and product choice get the time they need.
A job near Stotfold Common is typically 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.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Fire stopping in Stotfold Common: the local picture
Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Stotfold Common lies roughly 37 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.
Large healthcare estates like Fairfield Hospital (to the south of Stotfold Common) change their services often, so penetration seals are worth checking after M&E work. Holiday works at schools like St Mary's CofE Academy Stotfold often leave service openings to seal before pupils return. Halls and meeting rooms at places like Church of Saint Guthlac sometimes gain new services, and any compartment wall crossed needs the specified seal.
Stotfold Common is about 3 miles north of Letchworth, in Hertfordshire. We cover commercial sites throughout Stotfold Common, for single jobs and planned programmes alike.

When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Reviewing a building’s overall fire safety
- Writing the fire-stopping specification
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.
Joints and surfaces we work on
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Check with the data sheet before painting over fire sealant
- Report damaged or disturbed seals as soon as they’re spotted
- Brief every trade that openings they make must be sealed
- Ask the designer to confirm details early on refits
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job; found late, it can be one of many.
From enquiry to sign-off
Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around Stotfold Common, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
Before we start on site
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- Send your site hours and access windows

General trades versus a specialist
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.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Cost factors for service penetrations
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Location, for remote and island sites
- The product specified
- Joint width, depth and condition
- Site requirements such as inductions and permits
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What to include in your enquiry
A few photographs plus some basic facts will normally do. It helps to include:
- Clear photographs of the problem areas
- Whether the building will be occupied during the work
- Asbestos survey details if the building is older
- 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. The first step is to speak to us on 01277 525 020 or send photos by email with what you know.
Common questions from Stotfold Common clients
Is Stotfold Common too small for you to travel to?
Not at all. Stotfold Common is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Is hospital work, at somewhere like Fairfield Hospital, something you do?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Can you reseal penetrations after our M&E works?
Yes, provided a specification covers them. Openings left by new services are among the most common jobs we see and we close them with the specified product.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Do you hold third-party fire-stopping installer certification?
No, and we’d rather be clear about that. Third-party schemes aren’t a legal requirement, but many clients and main contractors ask for them, so check your contract first. If it doesn’t require one, we can install the specified fire-rated sealant to its tested detail.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Different surfaces, different methods
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products.
