Fire stopping in Soberton, done properly
We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Soberton. We work on service gaps in risers, linear gaps at wall heads and pipe penetrations, and the usual reasons a site gets in touch are unsealed joints where partitions meet the slab and damaged fire seals in risers and voids. Searching for sealant specialists in Soberton? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
For a smaller site near Soberton, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Every job we finish is backed by a 12-month workmanship guarantee, in Soberton as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out
What shapes the price:
- Access and working height
- Distance, for remote addresses
- Induction, permit and paperwork requirements
- How much there is to seal
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a quote once you have the details.
What we need to price the job
There’s no need for a formal survey. A few details are enough to get going:
- When you need the work done
- The type of building and who uses it
- Specification clauses that apply
- Approximate linear metres or a joint schedule
Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or use the quote form.
For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
FAQs: Soberton
Will you take on work at estates like Waltham Business Park, close to Soberton?
Yes. Estates, retail parks and business parks around Soberton, Waltham Business Park among them, are all within reach. To start, just call the office on 01277 525 020 or send details through our quote form with the unit, the joints involved and your access times.
What happens to BS 476 references for fire stopping in Soberton?
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. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Can staff carry on working while you’re here?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Soberton, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- 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.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Share your working hours and any access restrictions
- Move anything stored against the joints

Advice
What the job involves on each surface
Drylining partitions
Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any that don’t are flagged.
Leave it or put it right?
Inspections and handover checks often pick up fire stopping. Late discoveries can delay handover while openings are reopened and resealed. Older rural buildings around Soberton 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.
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What else we do in Soberton
Service penetrations in Soberton buildings
Central London is about 59 miles from Soberton. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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. Either way, we install the specified product to its tested detail.
Older community buildings such as Church of St Peter that have been rewired or given new heating can have service gaps through walls worth checking against the specification. On a hospital site such as Knowle Hospital, 5.4 miles south-west of Soberton, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. For a school such as Droxford Junior School, penetration sealing fits best at the end of the summer works.
Soberton is about 6 miles north-west of Horndean, in Hampshire. Anywhere in SO32, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Soberton is one of 723 places we cover in Hampshire for service penetrations. Sites around Portsmouth have their own page, roughly 10 miles from Soberton.
We take on service penetrations across the SO32 postcode area. Among the streets we cover are High Street, Station Road and Long Road, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Droxford (1 mile north), Brockbridge (1 mile north), Soberton Heath (2 miles south), Hill Grove (2 miles west) and Southend (2 miles south) for service penetrations. Nearby towns on our patch include Winchester (11 miles north-west), Gosport (10 miles south), Havant (9 miles south-east), Eastleigh (9 miles west), Fareham (7 miles south-west) and Horndean (6 miles south-east).

General trades versus a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
