About our fire stopping in Penge
Facilities managers in Penge often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. Most enquiries involve snag lists that include open service penetrations and damaged fire seals in risers and voids, across joints between fire-resisting walls and floors, linear gaps at wall heads and pipe penetrations. One point of contact handles commercial sealant work in Penge from the first photos to the final walk-round, whether it’s one building or several.
In a London area such as Penge, buildings are refitted often, and every new cable, pipe or duct through a fire-resisting wall or floor leaves a gap. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Why act early in Penge
A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Failed sealant in a building in Penge can quickly affect neighbours, tenants or the floor below. Putting it right early is less disruptive than dealing with the consequences.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

A few photos plus some basic facts will normally do. Please tell us:
- Your programme or deadline

Building owners, agents and FMs in Penge
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Where services cross fire walls in Penge
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Penge has four care or nursing homes no more than 2 miles away. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.
For a hospital such as British Home & Hospital for Incurables, 2.1 miles west of Penge, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. Where a unit on an estate such as Franklin Industrial Estate, less than half a mile to the south-east of Penge, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.
Penge is about 1 mile west of Beckenham, in Greater London. Businesses, contractors and managing agents in Penge can call on us for service penetrations. Across Greater London, 764 places are covered, Penge among them. London is covered too, some 6 miles away.
We cover the SE20, SE19 and SE26 postcode districts for service penetrations. If your site is on High Street, Anerley Station Road and Station Road or close by, we can quote for service penetrations. Penge sits on or close to the A234, which helps when planning parking and deliveries for the job. Sites close to Penge are covered too, including Anerley (1 mile west), Crystal Palace (1 mile north-west), Sydenham (1 mile north), Gipsy Hill (1 mile north-west) and Upper Norwood (1 mile west). Further afield, our area takes in London (6 miles north), City of Westminster (8 miles north-west), Marylebone (8 miles north-west), Kensington (8 miles north-west), St Pancras (8 miles north) and Shoreditch (8 miles north).

Common questions from Penge clients
Does your area include sites such as Franklin Industrial Estate, near Penge?
Yes. Our area takes in Penge and its surroundings, with estates and business parks such as Franklin Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Do you work in occupied care homes around Penge?
Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.
Do you have third-party installer accreditation for fire stopping?
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. If your contract requires third-party installer certification, we are not the right fit for that package.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How much does the work cost?
Every job gets its own fixed quote. To get one, call 01277 525 020 or send details through our quote form.
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.
How a job runs
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. In Penge, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- Completed areas are checked with you, with the records agreed when we quoted.
Getting the site ready
- Clear stock, furniture or equipment away from the joints
- Tell us what induction or permit system the site runs
- Let building users know which areas are affected
Getting a fixed quote
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Related advice
Do you need fire stopping in Penge?
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and a product not tested for that movement may crack. The tested detail for a linear joint states the width and movement it covers.
Typical triggers for a call:
- Openings left by services added after handover
- Head-of-wall gaps with no fire seal
- Old intumescent sealant that has split away
- Openings found when ceilings come down for a refit
At a university such as King's College London (3.9 miles north of Penge), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
