Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Fire stopping for commercial buildings in Furner's Green
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and unsealed openings around new pipes and cables, on service gaps in risers, small duct penetrations where the tested detail allows and pipe penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Furner's Green, preparation and product choice get the time they need.
Barn and farm-building conversions near places like Furner's Green often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Our workmanship is guaranteed for 12 months, in Furner's Green as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common problems we fix in Furner's Green
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps. Linear joint details set a width range and movement capability, and the seal has to sit within them.
If one of these sounds familiar, it’s time for a closer look:
- Unsealed penetrations discovered above suspended ceilings
- Builders’ foam or ordinary silicone in compartment walls
- Service penetrations left open after M&E works
- Damaged fire seals in risers and voids
At a university such as University of Sussex, which lies south-west of Furner's Green, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Why it’s worth doing now in Furner's Green
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Converted and older buildings near places like Furner's Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Common questions from Furner's Green clients
Is a hospital such as Princess Royal Hospital somewhere you can work?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Furner's Green off your patch?
No. Places such as Furner's Green are covered as much as the big towns. 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.
Is the work guaranteed?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
What changes on 2 September 2029?
From 2 September 2029, Approved Document B in England drops its references to BS 476 classes, subject to the Government’s transitional arrangements. The European route, BS EN 13501-2, then applies. Your designer will choose products with the right evidence.
Are you insured?
Yes. Mastic Doctor is fully insured, public liability included.
What about RAMS and site documents?
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.
Is fire stopping in Scotland covered by different guidance?
Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Arrange inspection before areas are covered up
- Leave fire sealant to cure fully before covering it
- Agree the fire-stopping specification before services go in
- Check risers and ceiling voids after each round of works
During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Jobs in and around smaller places like Furner's Green are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- 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.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Let us know about inductions and permits
- Point out parking and an unloading spot
- Confirm the product named in the specification

Advice
Doing it in-house
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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
