Fire stopping for New Cross sites
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Include service cupboards in routine inspections
- Foam or ordinary sealant is never a fire-seal repair
- Get seals inspected before ceilings and boxing close
- Report damaged or disturbed seals as soon as they’re spotted
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.
How we handle fire stopping in New Cross
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. We work on pipe penetrations, service gaps in risers and cable penetrations, and the failures we are asked to look at most are openings found when ceilings come down for a refit and seals that don’t match their tested detail. Whoever orders the work in New Cross, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send photos by email and we’ll come back to it.

From enquiry to sign-off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. All of Greater London is in the ULEZ, and kerbside space in New Cross can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- 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.
- 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.
What we need from you
- Share the asbestos register for older buildings
- Tell staff and tenants when we’ll be in
- Tell us your opening times and when work is allowed

Signs you need fire stopping in New Cross
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint. The tested detail for a linear joint states the width and movement it covers.
What tends to prompt an enquiry:
- Unsealed openings around new pipes and cables
- Fire sealant pulled out of the opening
- Seals that don’t match their tested detail
- Head-of-wall gaps with no fire seal
Hotels such as Peckham Rooms Hotel, 1.3 miles to the west of New Cross, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.
Questions to ask before you book
- Proof of insurance
- Is the sealant right for the movement and the substrate?
- Their plan for phasing and protecting the area
- Their approach to joint depth and backing
Compartment walls and floors in New Cross
There are three care or nursing homes within about 2 miles of New Cross. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail.
For a unit at a site such as New Cross Gate Retail Park, 0.5 miles to the north-west of New Cross, any new service through a fire-resisting wall should be sealed to the tested detail. Theatres, wards and plant rooms at sites like University Hospital Lewisham (to the south-east of New Cross) all have compartment walls crossed by services.
New Cross is about 3 miles south-east of London, in Greater London. Any commercial site in New Cross is covered, for single jobs and planned programmes alike. Across Greater London, 764 places are covered, including New Cross.
Anyone looking for fire stopping in SE8, SE14 and SE4 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Why act early in New Cross
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Site staff or a sealant specialist?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Questions about New Cross
Do you work on fire-rated sealing in hotels in New Cross?
Yes, to the specification and the product’s tested detail. Each seal follows the tested detail, and rooms are done in turn.
Will you take on work at estates like New Cross Gate Retail Park, close to New Cross?
Yes. We cover New Cross and the area around it, including industrial estates, business parks and retail parks such as New Cross Gate Retail Park. Photos and a short description are enough for a first look.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How many days will you need on site?
That varies with the scale of the job, though a typical visit normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
