Fire stopping for commercial buildings in Test Valley
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. Site teams most often ask us about old intumescent sealant that has split away and open linear gaps along the top of fire-resisting walls, on linear gaps at wall heads, pipe penetrations and service gaps in risers. A specialist sealant contractor works differently from a general builder: on jobs in Test Valley, preparation and product choice get the time they need.
Smaller places such as Test Valley still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
How the job changes by surface
Small ducts
Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on, so we check each one.
What we can’t put right
A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:
- Fire risk assessments, a job for a competent assessor
- Issuing fire ratings or certificates for seals
- Writing the fire-stopping specification
If in doubt, phone 01277 525 020 or send details through our quote form and we will say what we think before you book.
Surfaces we seal
- Cable penetrations
- Linear gaps at wall heads
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Service gaps in risers
- Joints between fire-resisting walls and floors
Aftercare for building managers
For the best life from the joints:
- Foam or ordinary sealant is never a fire-seal repair
- Leave fire sealant to cure fully before covering it
- Settle who seals which penetrations at the start of a project
- Brief every trade that openings they make must be sealed
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts.
Common questions from Test Valley clients
How does the move away from BS 476 affect penetration seals in Test Valley?
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. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Do you design the fire stopping for buildings in Test Valley?
No, that sits with the designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.
What if there’s asbestos in the old mastic?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
When can the area be used after sealing?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How do we ask for a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Quoting for work in Test Valley
Each job is priced on its own details. The things that drive the figure:
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
- How much there is to seal
- Removal of failed or old sealant
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.
Before you send an enquiry
It doesn’t need to be a full survey. These details are enough to start:
- Any specification or named product
- Asbestos survey details if the building is older
- What the building is and how it’s used
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
Fire-rated sealing for Test Valley buildings
Central London is about 59 miles from Test Valley. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. Our part stays the same: the specified product, installed to its tested detail.
Halls and meeting rooms at places like Church of St James sometimes gain new services, and any compartment wall crossed needs the specified seal. In a hotel such as Esseborne Manor Hotel, 1.3 miles south of Test Valley, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
