Why act early in St Cross
The longer openings stay, the more there tend to be: each new service adds to the list. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

About our fire stopping in St Cross
A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. Those on your schedule are closed with the specified product. We work on small duct penetrations where the tested detail allows, cable penetrations and linear gaps at wall heads, and what we’re called in for most is old intumescent sealant that has split away and openings found when ceilings come down for a refit. A specialist sealant contractor works differently from a general builder: on jobs in St Cross, preparation and product choice get the time they need.
Fire-rated sealing in a place like St Cross is typically a single building at a time. Send the specification, drawings or photos of the openings and we’ll quote to suit.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What else we do in St Cross
Surface by surface
Drylining partitions
Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.
Masonry and concrete
Many seals are made in blockwork, brickwork or concrete slabs. Dust and debris are cleared from the opening, with backing added if the detail requires it.
When to call us in St Cross
Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
What tends to prompt an enquiry:
- Unsealed joints where partitions meet the slab
- Unsealed openings around new pipes and cables
- Penetration schedules that need working through
- Old intumescent sealant that has split away
At a university such as University of Winchester, 0.9 miles to the north of St Cross, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.
What your quote should include
- The named product and why it was chosen
- How the joint faces will be prepared and primed
- Their public liability cover
- Are they CHAS accredited or on Constructionline?
What sets the cost
Quotes vary with the job. It mainly depends on:
- Whether old sealant has to be cut out first
- Specialist products, such as fire-rated or hygienic sealants
- Quantities, in metres or numbers
- Phasing around occupants
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Details that help us quote
There’s no need for a formal survey. A few details are enough to get going:
- The postcode of the building
- When you need the work done
- Specification clauses that apply
- Access details, including height
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.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.
Fire-rated sealing for St Cross buildings
Central London is about 62 miles from St Cross. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. A 2-mile radius around St Cross takes in a good number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.
Theatres, wards and plant rooms at sites like Royal Hampshire County Hospital, 0.8 miles north-west of St Cross, all have compartment walls crossed by services. Industrial units on estates such as Bar End Industrial Estate, 0.7 miles to the east of St Cross, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.
St Cross is about 1 mile south of Winchester, in Hampshire. Across the SO22 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. St Cross is one of 723 places we cover in Hampshire. Sites around Southampton have their own page, roughly 10 miles from St Cross.

Your questions answered
Is a hospital such as Royal Hampshire County Hospital somewhere you can work?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Does your area include sites such as Bar End Industrial Estate, near St Cross?
Yes. Our area takes in St Cross and its surroundings, with estates and business parks such as Bar End Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Is BS 476 being phased out?
It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications. Scotland follows its own Technical Handbook.
Can the sealant be colour-matched?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
Will fire-rated sealant work on every penetration?
No. A sealant’s evidence covers set services, gaps and wall or floor types. If an opening falls outside, it needs another solution, as set out by the designer.
How a job runs
Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. If neighbouring businesses or buildings around St Cross need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
Preparing the site
- Point out any areas we must not close
- For older buildings, check the asbestos register before work
- Make sure the joints can be reached
