How a job runs
Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Gilbert Street, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- First we confirm the product and tested details named in the specification.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
Before we start on site
- Arrange parking or a loading space
- Send any specification or drawings in advance
- Send asbestos survey details if the building is pre-2000
Quotes
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
Advice
About our fire stopping in Gilbert Street
No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. If you are dealing with open linear gaps along the top of fire-resisting walls and hidden openings found during inspections, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Gilbert Street it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Around smaller places like Gilbert Street, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, call the office on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

What else we do in Gilbert Street
When something else is needed
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Reviewing a building’s overall fire safety
- Signing off or certifying a building’s fire stopping
- Walls or floors that aren’t fire-resisting to begin with
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.
Where we work in Gilbert Street
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Joints between fire-resisting walls and floors
- Pipe penetrations
- Service gaps in risers
Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Common problems we fix in Gilbert Street
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls, which then have to be put right.
Site and facilities staff are often the first to spot these:
- Fire-rated sealant that has cracked or shrunk back
- Seals disturbed by maintenance and left open
- Builders’ foam or ordinary silicone in compartment walls
- Service penetrations left open after M&E works
Office fit-outs on sites such as Lower Soldridge Business Park, 1.7 miles to the north of Gilbert Street, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Different surfaces, different methods
Linear joints
Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, with no gaps along the run.
Drylining partitions
Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers first.
Fire stopping in Gilbert Street: the local picture
At about 51 miles from central London, Gilbert Street is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product. Fire stopping of openings and penetrations in England falls under 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.
Large healthcare estates like Alton Community Hospital (to the north-east of Gilbert Street) change their services often, so penetration seals are worth checking after M&E work. In a school such as Ropley Church of England Primary School, fire-rated sealant goes in around service penetrations where it is specified.
Gilbert Street is about 6 miles south-west of Alton, in Hampshire. Our applicators travel to Gilbert Street for work on service penetrations, handled exactly as we handle every other area. Our Hampshire coverage takes in 723 places. We also cover Southampton, some 18 miles away.

Gilbert Street: questions and answers
Can you take on a job at a hospital such as Alton Community Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Gilbert Street?
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.
How long does a typical visit take?
That varies with the scale of the job, but the work typically takes anything from one day to a planned run of visits, depending on the number of seals and the access. For bigger or phased jobs, we will set out a timescale with the quote.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Who decides which product is used?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
For managing agents and facilities managers
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
