Questions about Itchen
Is a hospital such as Royal South Hants Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you work on fire-rated sealing in hotels in Itchen?
Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
How much does the work cost?
There isn’t a price list, as every site differs. Send photographs or drawings and we will price it at a fixed figure.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Can you quote from photographs?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
How we handle fire stopping in Itchen
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings. Tell us what records you need and we will confirm with the quote. The enquiries we see most involve fire stopping installed outside its tested range and builders’ foam or ordinary silicone in compartment walls, on cable penetrations, joints between fire-resisting walls and floors and service gaps in risers. Facilities teams, main contractors and managing agents in Itchen tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Buildings in a smaller place such as Itchen 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.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

How a job runs
When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, and the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For a job in Itchen, the main thing is a clear picture of the work, so send photos of each area. A fixed quote follows.
- 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.
- Foam, ordinary sealant and debris come out.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Move anything stored against the joints
- Let us know about inductions and permits
- Have the specification and drawings to hand

Common problems we fix in Itchen
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Things that normally lead to an enquiry:
- Fire-rated sealant that has cracked or shrunk back
- Fire-stopping items raised at inspection or handover
- Unsealed openings around new pipes and cables
- Unsealed joints where partitions meet the slab
Colleges such as Southampton City College Marine Skills Centre (0.5 miles west of Itchen) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Fire stopping around Itchen: points for this area
Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. A 2-mile radius around Itchen takes in plenty of hotels. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product.
Campus buildings at universities such as Solent University (to the west of Itchen) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Wherever services are added at a hospital such as Royal South Hants Hospital (to the north-west of Itchen) the compartment line has to be made good with the specified product.
Itchen is about 2 miles south-east of Southampton, in Southampton. Anywhere in SO19, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Southampton, 30 places are covered, Itchen among them.

What sets the cost
We price every job individually. The main factors are:
- Whether the work must be split into stages
- Travel to remote or island sites
- Removal of failed or old sealant
- Any access equipment needed
The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Any specification or named product
- Whether an asbestos survey exists
- Photos of the joints, close up and from further back
- The postcode of the building
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.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Signing off or certifying a building’s fire stopping
- Construction that lacks the fire resistance the seal relies on
- Writing the fire-stopping specification
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Record which product was used where
- Look above ceilings when tiles are lifted for other jobs
- Brief every trade that openings they make must be sealed
- Get seals inspected before ceilings and boxing close
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.
Different surfaces, different methods
Masonry and concrete
Block walls and concrete floors are common substrates for penetration seals. Dust and loose debris are cleared out of the opening, so the sealant and any backing sit properly.
Small ducts
Ducts are only sealed with sealant where the detail allows it. Dampers and ductwork systems themselves are outside our work.
