About our fire stopping in St Helen's
Facilities managers in St Helen's often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it. Where there isn’t one, the designer or fire engineer needs to set one first. Site teams most often ask us about fire sealant pulled out of the opening and penetration schedules that need working through, across joints between fire-resisting walls and floors, linear gaps at wall heads and service gaps in risers. Looking for mastic applicators who cover St Helen's? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
Buildings in a smaller place such as St Helen's that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Fire risk assessments, a job for a competent assessor
- Construction that lacks the fire resistance the seal relies on
- Large openings beyond what any sealant detail covers
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.
What we seal
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Ask which product is in place before decorating
- Record which product was used where
- Arrange inspection before areas are covered up
- Flag new cables with no seal around them
Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.
Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.
Signs you need fire stopping in St Helen's
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in, which then have to be put right.
It’s worth sending us details if you spot any of the following:
- Fire-stopping items raised at inspection or handover
- Damaged fire seals in risers and voids
- Fire sealant pulled out of the opening
- Open linear gaps along the top of fire-resisting walls
Tenant changes at centres like Priory Meadow Shopping Centre (1.2 miles south of St Helen's) often mean new services through walls between units.
Before you book anyone
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- How they handle RAMS and site documents
- Can the work be phased to keep areas open?
- What level of public liability insurance do they hold?
Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in St Helen's, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Getting the site ready
- Send any specification or drawings in advance
- Share the asbestos register for older buildings
- Tell staff and tenants when we will be in

FAQs: St Helen's
Do you work in occupied care homes around St Helen's?
Yes, with the manager deciding the order and timing of rooms. We follow the home’s own procedures throughout.
Is hospital work, at somewhere like Conquest Hospital, something you do?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Do you approve fire stopping for building control?
No. Sign-off belongs to the designer or building control, not the installer. We’ll confirm the product and detail installed and agree any further records when we quote.
What will the job cost?
There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Why it’s worth doing now in St Helen's
An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.
