About our fire stopping in Porchfield
Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. Site teams most often ask us about unsealed penetrations discovered above suspended ceilings and damaged fire seals in risers and voids, on service gaps in risers, small duct penetrations where the tested detail allows and cable penetrations. For commercial sealant work in Porchfield, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Rural conversions around Porchfield can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or send details through our quote form and we will arrange a return visit.

Signs you need fire stopping in Porchfield
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.
Typical triggers for a call:
- Head-of-wall gaps with no fire seal
- Fire stopping installed outside its tested range
- Expanding foam used as fire stopping
- Penetration schedules that need working through
Tenant changes at parks like Porchfield Business Park (to the south-west of Porchfield) bring new data and services, and openings through fire-resisting walls need the specified seal.
What to look for in a quote
- Do they follow the manufacturer’s priming guidance?
- Is the sealant right for the movement and the substrate?
- Will CSCS-carded applicators be on site?
- Are they CHAS accredited or on Constructionline?
Your questions answered
Is a smaller place like Porchfield outside your area?
No. Places such as Porchfield are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you take on work at healthcare sites like Mr Rohan Sawant (St Mary’s Hospital)?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or email us. Include photographs or drawings if you have them.
What will the job cost?
Every job gets its own fixed quote. To get one, call 01277 525 020 or email a schedule or drawings.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Which sealant will you use?
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.
For managing agents and facilities managers
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Porchfield can sit alongside others in a wider programme.
Surface by surface
Linear joints
Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in, with no gaps along the run.
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.
Quoting for work in Porchfield
What shapes the price:
- The size and state of each joint
- The product specified
- Induction, permit and paperwork requirements
- Travel to remote or island sites
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
Details that help us quote
The more we know, the firmer the quote. Helpful details to send:
- How the joints are reached, and at what height
- Specification clauses that apply
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.
When it isn’t the sealant
Being straight saves everyone time. Fresh joints won’t solve:
- Signing off or certifying a building’s fire stopping
- Openings that need collars, wraps, batts or boards rather than sealant
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, give us a call on 01277 525 020 or email drawings and photos and we’ll say what we think.
What we seal
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Service gaps in risers
- Pipe penetrations

On site: what to expect
Tell us your site hours and access windows and we will plan around them. 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. If others near Porchfield need work, visits can be combined. A fixed quote is given before anything starts.
- First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
- Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Agree which areas must stay open
- Tell staff and tenants when we’ll be in
- Tell us your opening times and when work is allowed
