About our fire stopping in Wallington
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, call 01277 525 020 or send details through our quote form with the schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we’ll confirm with the quote. We work on service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are fire stopping installed outside its tested range and openings found when ceilings come down for a refit. Looking for mastic applicators who cover Wallington? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we will confirm with the quote.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Reviewing a building’s overall fire safety
- Approving the work on behalf of building control
- Deciding what a wall or floor needs, which belongs to the designer
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly.
What we seal
- Joints between fire-resisting walls and floors
- Cable penetrations
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Service gaps in risers
- Linear gaps at wall heads
After the work
Keep the joints in good shape with a few simple steps:
- Settle who seals which penetrations at the start of a project
- Treat an open penetration as a priority repair
- Look above ceilings when tiles are lifted for other jobs
- Put resealing into every M&E and fit-out package
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.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate, and it helps at inspections.
Your questions answered
Can work in a care setting near Wallington go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.
Will you take on work at estates like Anchor Business Park, close to Wallington?
Yes, sites like Anchor Business Park are within our area, along with the rest of Wallington. A few photos and the unit address let us price the work.
Can weather delay the job?
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.
What does an EI 60 rating mean?
In short, BS EN 1366-3 and 1366-4 are the fire tests and BS EN 13501-2 is how results are classified. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.
How much does the work cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.
Do you hold third-party fire-stopping installer certification?
No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. Where a client or main contractor requires a scheme member, we will say so straight away rather than waste your time.
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.
When to call us in Wallington
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.
Most enquiries start with something like this:
- Openings found when ceilings come down for a refit
- Non-fire-rated filler around services
- Open linear gaps along the top of fire-resisting walls
- Damaged fire seals in risers and voids
In a retail centre such as Whitgift Centre (2.3 miles east of Wallington), any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail.
What to look for in a quote
- How long is the guarantee, and what does it include?
- Do they follow the manufacturer’s priming guidance?
- Their pre-qualification and accreditations
- Will failed sealant be removed rather than covered?
On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. 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. Planning a London job such as one in Wallington starts with access. Give us the hours we can be on site and we will schedule to suit.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
What we need from you
- Arrange parking or a loading space
- Let us know about inductions and permits
- Tell us your opening times and when work is allowed

What else we do in Wallington
Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed which is why earlier is better. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Why clients in Wallington choose us
- Our applicators hold CSCS cards
- Old sealant cut out, never sealed over
- Fixed quotes based on photos, drawings or a visit
- Constructionline member

Fire stopping around Wallington: how the place shapes the job
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Penetrations are sealed with the specified product, to its tested detail, under the building’s own permit rules. Wallington has two care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. We install fire-rated sealant to the tested detail where it is specified.
Hotels such as The Waddon Hotel (1.5 miles east of Wallington) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. At a healthcare site like Queen Mary's Childrens' Hospital, 1.8 miles north-west of Wallington, new services through compartment walls are a constant, and each needs the specified seal.
Wallington is about 2 miles west of Croydon, in Greater London. We send applicators to Wallington for service penetrations, handled exactly as we handle every other area.
