Fire stopping for commercial buildings in Nash Street
On a fit-out or refurbishment, we follow the services contractors floor by floor. To price a package, give us a call on 01277 525 020 or use the 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 pipe penetrations, linear gaps at wall heads and joints between fire-resisting walls and floors, and what we are called in for most is builders’ foam or ordinary silicone in compartment walls and improvised or mixed-product fire seals. Whoever orders the work in Nash Street, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Nash Street, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
A 12-month guarantee applies to all our work in East Sussex. Should something we installed fail, phone 01277 525 020 or email the details over and we’ll come back to it.

From enquiry to sign-off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. If others near Nash Street need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- We read the specification, drawings or penetration schedule you send 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.
Getting the site ready
- Share your working hours and any access restrictions
- Make sure the joints can be reached
- Tell staff and tenants when we’ll be in
Ask for a quote
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
Advice
Places near Nash Street

When to bring in a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
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.
When to call us in Nash Street
Head-of-wall joints and wall-to-wall junctions are frequent weak points. Movement in the frame or slab can open the joint, and the wrong product can split as a result. Linear joint details set a width range and movement capability, and the seal has to sit within them.
These are often picked up first by site or facilities staff:
- Fire-rated sealant that has cracked or shrunk back
- Snag lists that include open service penetrations
- Fire stopping installed outside its tested range
- Seals disturbed by maintenance and left open
For a unit at a centre such as Hailsham Retail Park (2.9 miles south-east of Nash Street), penetration seals are worth checking after each shop fit.
What to look for in a quote
- Can the work be phased to keep areas open?
- Is the sealant right for the movement and the substrate?
- Will failed sealant be removed rather than covered?
- Health and safety accreditation such as CHAS
Owners, agents and contractors
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
What happens if it’s left?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach and each detail can be checked as we go. Halls, stores and units around places like Nash Street may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Your questions answered
Do you take on work at healthcare sites like Hellingly Hospital Railway?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Oakwood Business Park, near Nash Street, within your area?
Yes. We cover Nash Street and the area around it, including industrial estates, business parks and retail parks such as Oakwood Business Park. A few photos and the unit address let us price the work.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Do you approve fire stopping for building control?
No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. We work to the specification and the manufacturer’s installation guidance.
Do you cover Nash Street?
Yes. We cover Nash Street, and you can call 01277 525 020 or use the quote form to get started.
Can you tell us what fire stopping our building needs?
No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements, and tell you if a detail needs another product.
Do the same rules apply to fire stopping in Scotland?
Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor.

Where services cross fire walls in Nash Street
The area within 2 miles of Nash Street holds a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. In England, Approved Document B covers fire stopping of openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Holiday works at schools like Chiddingly Primary School often leave service openings to seal before pupils return. Office fit-outs on sites such as Oakwood Business Park, 0.5 miles south-west of Nash Street, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
