Fire stopping for commercial buildings in Chandler's Ford
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on cable penetrations, service gaps in risers and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are unsealed openings around new pipes and cables and improvised or mixed-product fire seals. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Chandler's Ford, preparation and product choice get the time they need.
In a town like Chandler's Ford, penetration seals typically need attention after other trades have been through. Checking after M&E works is good practice, and we will seal what’s found where fire-rated sealant is the specified product.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Questions about Chandler's Ford
What does the BS 476 change mean for fire-rated sealant in Chandler's Ford?
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.
Could you schedule work at a campus like University of Southampton for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Are you CHAS accredited?
Yes. We’re CHAS accredited and a Constructionline member.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
What sealant work can’t fix
Being straight saves everyone time. Fresh joints won’t solve:
- Plastic pipes whose detail calls for a collar or wrap
- Walls or floors that aren’t fire-resisting to begin with
- Fire doors, dampers or other fire safety equipment
If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer.
Surfaces we seal
- Cable penetrations
- Pipe penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
Looking after the joints
Regular inspection catches problems early. In particular:
- Keep general-purpose fillers away from compartment walls
- Agree the fire-stopping specification before services go in
- Brief every trade that openings they make must be sealed
- Include service cupboards in routine inspections
New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.

Fire-rated sealing for Chandler's Ford buildings
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Chandler's Ford lies roughly 66 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.

On site: what to expect
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Town-centre premises in Chandler's Ford may have limited parking, so tell us what’s nearby. On estates and business parks it’s typically simpler.
- First we go through the drawings, schedule or specification for the seals.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- If an opening needs something other than sealant, we tell you instead of improvising.
What we need from you
- Tell us which areas need to stay in use
- Explain the parking and delivery arrangements
- Tell staff and tenants when we will be in
Quotes
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Common problems we fix in Chandler's Ford
Some service penetrations were never sealed at all. Inspections, refurbishments and ceiling access typically bring them to light.
Look out for the following:
- Old intumescent sealant that has split away
- Seals disturbed by maintenance and left open
- Openings found when ceilings come down for a refit
- Unsealed openings around new pipes and cables
Colleges such as Barton Peveril Sixth Form College, 1.9 miles to the south-east of Chandler's Ford, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.
What your quote should include
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Health and safety accreditation such as CHAS
- How the existing material will be dealt with
- What level of public liability insurance do they hold?
What the job involves on each surface
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
