Common questions from South Warnborough clients
Is South Warnborough too far out for you?
Not at all. South Warnborough is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in South Warnborough?
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. Our part doesn’t change: the specified product, to its tested detail.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a quote.
Can you fit around our working hours?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
About our fire stopping in South Warnborough
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations, and what we’re called in for most is head-of-wall gaps with no fire seal and fire sealant pulled out of the opening. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in South Warnborough, that means joint design, primers and backing rod as standard.
Around smaller places like South Warnborough, 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.
Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we’ll arrange a return visit.

Owners, agents and contractors
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

When to call us in South Warnborough
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 usually bring them to light.
Things that usually lead to an enquiry:
- Seals that don’t match their tested detail
- Openings left by services added after handover
- Hidden openings found during inspections
- Old intumescent sealant that has split away
Older community buildings such as Church of St Andrew that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What to look for in a quote
- How the joint faces will be prepared and primed
- Which product they’ll use, and why it suits the joint
- Their public liability cover
- Health and safety accreditation such as CHAS
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Older rural buildings around South Warnborough move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Cost factors for service penetrations
Before we quote, we look at:
- Backing rod, priming and other preparation
- Quantities, in metres or numbers
- Location, for remote and island sites
- Removal of failed or old sealant
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.
What we need to price the job
We can often quote from photos and a few details. Please tell us:
- Drawings or a marked-up plan, if available
- Clear photos of the problem areas
- What the building is and how it’s used
- Where the site is, with the postcode
Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to call 01277 525 020 or email the details over.
Diagnose, treat, sign off
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For work around South Warnborough, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
What we need from you
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000
- Confirm the product named in the specification
Ask for a quote
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
Should maintenance staff do it?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
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.
Penetration seals near South Warnborough
Approved Document B is the English guidance that covers fire stopping around 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. Either way, we install the specified product to its tested detail. South Warnborough is about 42 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
For a hospital such as Alton Community Hospital, 5.8 miles to the south of South Warnborough, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. Schools such as Robert May's School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
