About our fire stopping in Crumbles
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on service gaps in risers, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the usual reasons a site gets in touch are builders’ foam or ordinary silicone in compartment walls and improvised or mixed-product fire seals. Whoever orders the work in Crumbles, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Smaller places such as Crumbles still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Cost factors for service penetrations
To price the job, we consider:
- Whether old sealant has to be cut out first
- Location, for remote and island sites
- The total length or number of joints
- Specialist products, such as fire-rated or hygienic sealants
Pricing service penetrations depends on how many there are, their condition and the access. Ask us for a fixed quote.
What we need to price the job
However big the job, the same details help:
- Rough lengths or quantities, or drawings if you have them
- Your programme or deadline
- Clear photos of the problem areas
- The postcode of the building
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Where services cross fire walls in Crumbles
Central London is about 52 miles from Crumbles. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. Crumbles has several hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Hotels like Bay Hotel (to the north-east of Crumbles) are refurbished in phases, and each phase can open up compartment walls. For a hospital such as Eastbourne District General Hospital, 2.9 miles to the west of Crumbles, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. Shop fits on retail sites such as Sovereign Harbour Village Retail Park, 0.5 miles west of Crumbles, can bring new services through fire-resisting walls between units, to be sealed with the specified product.
Crumbles is about 2 miles east of Eastbourne, in East Sussex. Any commercial site in Crumbles is covered, for single jobs and planned programmes alike. Crumbles is one of 308 places we cover in East Sussex for service penetrations. We also cover Brighton, some 20 miles away.
Commercial sites across BN23 are covered. Buildings on Tambora Square, Long Beach View and Golden Gate Way are within our area. Sites close to Crumbles are covered too, including Langney (1 mile west), Pevensey Bay (1 mile north-east), Pevensey (2 miles north), Westham (2 miles north-west) and Stone Cross (2 miles north-west).

Local landmarks in Crumbles
We work on buildings around The Haven Voluntary Aided CofE/Methodist Primary School and Princes Park. Crumbles’s nearest station is Pevensey & Westham station, roughly 1.3 miles north of the centre. Well-known places in the area include Pevensey Court House Museum And Gaol (1.6 miles north) and Pevensey Castle (1.5 miles north). Not far away are Combe Hill.
Site staff or a sealant specialist?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Why deal with it now?
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. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Older rural buildings around Crumbles move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

- Issuing fire ratings or certificates for seals
- Fire risk assessments, a job for a competent assessor
If in doubt, ring 01277 525 020 or email us and we’ll say what we think before you book.

FAQs: Crumbles
What does the BS 476 change mean for fire-rated sealant in Crumbles?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can you seal penetrations in a hotel in Crumbles after a refit?
Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
