About our fire stopping in West Liss
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and pipe penetrations, and what we’re called in for most is unsealed penetrations discovered above suspended ceilings and unsealed openings around new pipes and cables. Most enquiries from West Liss start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
A job near West Liss is usually planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Large openings beyond what any sealant detail covers
- Reviewing a building’s overall fire safety
Not sure which it is? You can speak to us on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

FAQs: West Liss
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in West Liss?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Can you work at a site such as Upper Adhurst Industrial Park, by West Liss?
Yes. Our area takes in West Liss and its surroundings, with estates and business parks such as Upper Adhurst Industrial Park included. A few photos and the unit address let us price the work.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we’ll schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
When is resealing likely to be due?
There isn’t a single answer, 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.

On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around West Liss, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We read the specification, drawings or penetration schedule you send and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Point out parking and an unloading spot
- Make sure the joints can be reached
- Tell staff and tenants when we’ll be in

What the job involves on each surface
Cables and cable bundles
New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail, and we tell you if the bundle exceeds what sealant covers.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area and tell you about openings outside the list.
Where services cross fire walls in West Liss
West Liss lies roughly 47 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. In England, Approved Document B covers fire stopping of 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. What we install is set by the specification, and it goes in to the tested detail.
Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. On a hospital site such as Petersfield Community Hospital, 3.2 miles south-west of West Liss, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Signs you need fire stopping in West Liss
Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access normally bring them to light.
What tends to prompt an enquiry:
- Expanding foam used as fire stopping
- Openings found when ceilings come down for a refit
- Damaged fire seals in risers and voids
- Snag lists that include open service penetrations
Holiday works at schools like Liss Infant School often leave service openings to seal before pupils return.
What your quote should include
- Whether their applicators hold CSCS cards
- Will RAMS and insurance details be available?
- Is the sealant right for the movement and the substrate?
- Are they CHAS accredited or on Constructionline?
Site staff or a sealant specialist?
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
