About our fire stopping in Hemsted
Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve unsealed joints where partitions meet the slab and unsealed openings around new pipes and cables, across joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and service gaps in risers. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Hemsted is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a smaller site near Hemsted, we plan to do all the penetrations in one go, 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 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

When to bring in a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
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.

Service penetrations in Hemsted buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. We install whatever has been specified, to the product’s tested detail. Hemsted is about 56 miles from central London. 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. For a school such as Stowting Church of England Primary School, penetration sealing fits best at the end of the summer works.

FAQs: Hemsted
Is Hemsted too far out for you?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
Can you produce the fire-stopping design for a job in Hemsted?
No, that sits with the designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.
Can staff carry on working while you’re here?
Usually, yes. Phased work can be planned so areas stay in use.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Looking after the joints
To get the most from the new sealant:
- Foam or ordinary sealant is never a fire-seal repair
- Put resealing into every M&E and fit-out package
- Flag new cables with no seal around them
- Include service cupboards in routine inspections
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Honest limits
Honesty saves time and money. Fresh joints won’t solve:
- Fire risk assessments, a job for a competent assessor
- Plastic pipes whose detail calls for a collar or wrap
- Issuing fire ratings or certificates for seals
If you are not sure, just call the office on 01277 525 020 or email us and we’ll give you a straight answer before you book.

How the job changes by surface
Masonry and concrete
Openings through concrete vary from tidy cores to rough break-outs. The gap is measured at the widest point against the detail’s limits.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a building around Hemsted, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We read the specification, drawings or penetration schedule you send.
- 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.
- 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.
What we need from you
- Arrange parking or a loading space
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints
