Commercial clients in New Addington
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. New Addington can form part of a wider programme.
Fire stopping in New Addington
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. We work on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations, and the usual reasons a site gets in touch are penetration schedules that need working through and service penetrations left open after M&E works. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in New Addington it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a London area such as New Addington, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Each service penetration gets fire-rated or intumescent sealant if that’s what is specified, laid to the product’s tested arrangement.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Questions we are asked in New Addington
Would you work within a site like Bethlem Royal Hospital?
Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
What do BS EN 1366-3 and BS EN 13501-2 mean?
The tests are BS EN 1366-3 for penetrations and BS EN 1366-4 for linear joints, and classification is to BS EN 13501-2. EI 60 means integrity and insulation for 60 minutes in the tested arrangement and the installation has to match the test.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.
Are you insured?
Yes. We’re fully insured, including public liability cover.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Fire stopping in New Addington: the local picture
With tenants changing and fit-outs following, London buildings see service routes altered again and again. We seal to the specification and the product’s tested detail, working within the building’s permits. For England, the fire stopping of penetrations is dealt with in 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.
Halls and meeting rooms at places like St Edward King and Confessor sometimes gain new services, and any compartment wall crossed needs the specified seal. On estates like Vulcan Way Industrial Estate, 0.6 miles to the east of New Addington, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Hospital estates such as Bethlem Royal Hospital (2.8 miles north of New Addington) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

Landmarks near New Addington
We work on buildings around Meridian High School and Addington Vale. For rail, the closest station is Hayes (Kent) station, roughly 2.6 miles north-east of the centre. Well-known places in the area include Warlingham Park Hospital (1.8 miles south) and Bethlem Museum of the Mind (3.3 miles north-east). Not far away are Nore Hill and Hutchinson's Bank.
General trades versus a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
After the work
Once the work is signed off, these steps help:
- Keep general-purpose fillers away from compartment walls
- Get seals inspected before ceilings and boxing close
- Brief every trade that openings they make must be sealed
- Check risers and ceiling voids after each round of works
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
Cost factors for service penetrations
Before we quote, we look at:
- Access and working height
- Induction, permit and paperwork requirements
- Quantities, in metres or numbers
- Location, for remote and island sites
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
Diagnosis starts before we arrive. Let us know:
- Where the site is, with the postcode
- A wide shot and a close-up of the area
- The asbestos register, for older buildings
- Whether the building will be occupied during the work
Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do.
Our process
When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes anything from one day to a planned run of visits, depending on the number of seals and the access. All of Greater London is in the ULEZ, and kerbside space in New Addington can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- Unsuitable fillers and loose debris are taken out of each opening.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Let building users know which areas are affected
- Confirm the product named in the specification
- Share the asbestos register for older buildings
