Fire stopping for commercial buildings in Nether Wallop
It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance. Site teams most often ask us about unsealed joints where partitions meet the slab and damaged fire seals in risers and voids, across cable penetrations, linear gaps at wall heads and pipe penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Nether Wallop it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a smaller site near Nether Wallop, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email us and we’ll arrange a return visit.

For managing agents and facilities managers
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Nether Wallop can form part of a wider programme.
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Smaller jobs around Nether Wallop can be grouped with others nearby. You’ll have a fixed quote before work starts.
- 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.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Confirm the product named in the specification
- For older buildings, check the asbestos register before work

Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Brief every trade that openings they make must be sealed
- Get seals inspected before ceilings and boxing close
- Check with the data sheet before painting over fire sealant
- Look above ceilings when tiles are lifted for other jobs
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.
Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
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.
How the job changes by surface
Cables and cable bundles
Single cables and small bundles are often within a fire-rated sealant’s tested detail. The detail limits bundle size and the gaps between and around cables, so we check before sealing.
Small ducts
Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.
Penetration seals near Nether Wallop
Nether Wallop is about 69 miles from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. We install whatever has been specified, to the product’s tested detail.
In a hotel such as Fifehead Manor Hotel (1.2 miles north-west of Nether Wallop), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. For a building such as Church of St Andrew, new heating or data runs are the usual reason penetrations need sealing. For a school such as Wallop Primary School, penetration sealing fits best at the end of the summer works.

Questions we’re asked in Nether Wallop
Can you produce the fire-stopping design for a job in Nether Wallop?
No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.
Is Nether Wallop too far out for you?
No. Places such as Nether Wallop are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Are you CHAS accredited?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Will your applicators have CSCS cards?
Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
How long does a job like this take?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
