Fire stopping in Walderslade, done properly
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you have unsealed joints where partitions meet the slab and seals disturbed by maintenance and left open, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Walderslade is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Converted and extended buildings around places like Walderslade can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Honest limits
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Fire doors, dampers or other fire safety equipment
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Openings that need collars, wraps, batts or boards rather than sealant
If you are not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.
What we seal
- Linear gaps at wall heads
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Joints between fire-resisting walls and floors
- Cable penetrations
- Service gaps in risers
Why act early in Walderslade
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is typically a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
A quote for service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Quoting for work in Walderslade
These are the things that shape the price:
- Any access equipment needed
- Site requirements such as inductions and permits
- Working within restricted access windows
- How much existing material needs removing
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
Sending details for a quote
However big the job, the same details help:
- A wide shot and a close-up of the area
- Rough lengths or quantities, or drawings if you have them
- Specification clauses that apply
- The type of building and who uses it
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, call 01277 525 020 or use the quote form.
Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For a unit at a site such as Lordswood Industrial Estate, 1.1 miles to the south-east of Walderslade, new power or data runs between office and warehouse can breach a compartment wall.

Common questions from Walderslade clients
What does the BS 476 change mean for fire-rated sealant in Walderslade?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Can you work at a site such as Lordswood Industrial Estate, by Walderslade?
Yes. We cover Walderslade and the area around it, including industrial estates, business parks and retail parks such as Lordswood Industrial Estate. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
What will the job cost?
Every job gets its own fixed quote. To get one, give us a call on 01277 525 020 or email drawings and photos.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How long does a typical visit take?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit.
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. Several jobs near Walderslade can be grouped on one trip. Mention the building’s opening times and we’ll work within them.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Tell staff and tenants when we will be in
- Send asbestos survey details if the building is pre-2000
- Make sure the joints can be reached

Do you need fire stopping in Walderslade?
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps. The tested detail for a linear joint states the width and movement it covers.
Most enquiries start with something like this:
- Non-fire-rated filler around services
- Penetration schedules that need working through
- Open linear gaps along the top of fire-resisting walls
- Unsealed penetrations discovered above suspended ceilings
Halls and meeting rooms at places like St William's Church sometimes gain new services, and any compartment wall crossed needs the specified seal.
