Highfield: questions and answers
Do you work on fire-rated sealing in hotels in Highfield?
Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Is Highfield too far out for you?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Can staff carry on working while you are here?
Yes, with some planning. Tell us your site hours and access windows and we will plan around them.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can the sealant be colour-matched?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
About our fire stopping in Highfield
Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you’re dealing with hidden openings found during inspections and open linear gaps along the top of fire-resisting walls, we can help, whatever the surface. For commercial sealant work in Highfield, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Converted and extended buildings around places like Highfield can mix old and new construction, so the wall or floor a service passes through isn’t always what the drawings assume. We match the product to the substrate and service, and say so if a collar, wrap or batt is the specified item.
Our workmanship is guaranteed for 12 months, in Highfield as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Leave it or put it right?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. In a smaller place such as Highfield, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Signs you need fire stopping in Highfield
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position, so it has to come out.
Look out for the following:
- Seals that don’t match their tested detail
- Fire seals cut back for extra cables and never reinstated
- Old intumescent sealant that has split away
- Builders’ foam or ordinary silicone in compartment walls
For an estates team at a campus like University of Southampton, less than half a mile to the south of Highfield, summer M&E works are typically followed by a round of penetration sealing.
What your quote should include
- Will failed sealant be removed rather than covered?
- Will RAMS and insurance details be available?
- Can the work be phased to keep areas open?
- What level of public liability insurance do they hold?
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You’ll hear from us if the cause turns out to be any of the following:
- Construction that lacks the fire resistance the seal relies on
- Signing off or certifying a building’s fire stopping
- Reviewing a building’s overall fire safety
If you are not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.
Joints and surfaces we work on
- Service gaps in risers
- Pipe penetrations
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Diagnose, treat, sign off
We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a site in Highfield, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- We start with your penetration schedule, drawings or specification.
- Access, permits and the order of areas are agreed with the site team.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Point out any areas we must not close
- Make sure the joints can be reached
- Send any specification or drawings in advance

Advice
Compartments and services around Highfield
The 2 miles around Highfield include two care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. Central London is about 69 miles from Highfield. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.
For a hotel such as Highfield House Hotel, under half a mile to the south-east of Highfield, penetration seals are worth checking after any refit or services upgrade. On estates like Belgrave Industrial Estate, which lies east of Highfield, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.
