Fire stopping for commercial buildings in Southbourne
Facilities managers in Southbourne often find open service penetrations when ceilings come down for other work. 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 service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations, and the failures we are asked to look at most are seals disturbed by maintenance and left open and penetration schedules that need working through. Looking for mastic applicators who cover Southbourne? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Around smaller places like Southbourne, many commercial buildings are conversions or extensions of older ones, 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.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Questions about Southbourne
Is Southbourne too small for you to travel to?
Not at all. Southbourne is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you work on a hospital site such as Spire Hospital Portsmouth?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Is sealant suitable for all service openings?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we’ll tell you when that applies.
Do you work in Scotland as well as England?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance, using products tested for their end use.
Will you write the fire-stopping specification?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Commercial clients in Southbourne
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
When to call us in Southbourne
Damage plays a part too. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped.
Any of the following is a good reason to get the joints checked over:
- Fire sealant pulled out of the opening
- Service penetrations left open after M&E works
- Seals disturbed by maintenance and left open
- Unsealed joints where partitions meet the slab
Offices at parks like Hambrook Business Park (to the north-east of Southbourne) are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.
Questions to ask before you book
- Can the work be phased to keep areas open?
- What level of public liability insurance do they hold?
- How the existing material will be dealt with
- What the guarantee covers, and for how long

What else we do in Southbourne
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Writing the fire-stopping specification
- Plastic pipes whose detail calls for a collar or wrap
- Approving the work on behalf of building control
If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think before you book.
Where we work in Southbourne
- Small duct penetrations where the tested detail allows
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
Should maintenance staff do it?
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Our process
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. For a job in Southbourne, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Unsuitable fillers and loose debris are taken out of each opening.
- 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.
Preparing the site
- Share your working hours and any access restrictions
- Move anything stored against the joints
- Send asbestos survey details if the building is pre-2000

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
At a healthcare site like Spire Hospital Portsmouth, 2.4 miles to the north-west of Southbourne, new services through compartment walls are a constant, and each needs the specified seal. For a building such as St. John's, new heating or data runs are the usual reason penetrations need sealing.
