Need fire stopping in Great Leighs?
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Leave it or put it right?
Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. One visit to deal with every failing joint makes more sense than several trips to a place like Great Leighs. Photos of every joint help us quote for the whole job.
A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Fire stopping in Great Leighs
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. If you have fire seals cut back for extra cables and never reinstated and open linear gaps along the top of fire-resisting walls, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Great Leighs from the first photos to the final walk-round, whether it’s one building or several.
A job near Great Leighs is typically planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Different surfaces, different methods
Metal pipes
Metal pipes conduct heat, so their details often call for extra measures along the pipe, and some details add wrapping or a set length of insulation. If the detail needs something beyond sealant, we tell you.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access to these areas is planned with you in advance.
Where services cross fire walls in Great Leighs
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Great Leighs lies roughly 34 miles out 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 John the Evangelist, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a building at a site such as Banters Lane Business Park, which lies north-east of Great Leighs, a check of penetration seals after each fit-out is good practice. Large healthcare estates like William Julien Courtauld Hospital, 3.6 miles north-east of Great Leighs, change their services often, so penetration seals are worth checking after M&E work.

Your questions answered
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Great Leighs?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Is hospital work, at somewhere like William Julien Courtauld Hospital, something you do?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Will you come and look before quoting?
That depends on the size and complexity of the job. Simple work can often be priced from photos, and bigger or more complex jobs normally get a visit.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Who decides which product is used?
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.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Cost factors for service penetrations
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- The size and state of each joint
- The total length or number of joints
- Whether old sealant has to be cut out first
- Distance, for remote addresses
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.
Before you send an enquiry
The more we know, the firmer the quote. Helpful details to send:
- Whether the building will be occupied during the work
- Drawings or a marked-up plan, if available
- Where the site is, with the postcode
- Anything awkward about access or site hours
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or email drawings and photos.

Our process
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Smaller jobs around Great Leighs can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- 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.
Preparing the site
- Have the specification and drawings to hand
- Move anything stored against the joints
- Tell us which areas need to stay in use

For managing agents and facilities managers
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
We work for building owners and managing agents on everything from one building to a spread of sites around Great Leighs. Several sites can go on one quote, so there’s one set of paperwork to deal with.
Keeping the joints sound
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Put resealing into every M&E and fit-out package
- Ask the designer to confirm details early on refits
- Check risers and ceiling voids after each round of works
- Record which product was used where
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.
