About our fire stopping in Langrish
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. If you’re dealing with openings found when ceilings come down for a refit and fire-rated sealant that has cracked or shrunk back, we can put it right, on small duct penetrations where the tested detail allows, service gaps in risers and pipe penetrations alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Langrish it comes down to the same thing: the right product in a properly prepared joint.
For a smaller site near Langrish, we plan to do all the penetrations in one go, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Penetration seals near Langrish
Langrish lies roughly 52 miles out from central London. 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. In England, Approved Document B covers fire stopping of openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
For a building such as Church of St John the Evangelist, new heating or data runs are the usual reason penetrations need sealing. In a school such as Langrish Primary School, fire-rated sealant goes in around service penetrations where it is specified. Hospital estates such as Petersfield Hospital (2.3 miles east of Langrish) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Langrish is about 3 miles west of Petersfield, in Hampshire. We cover commercial sites throughout Langrish, whether it’s a single job or part of a planned programme. Langrish is one of 723 places in Hampshire on our list for service penetrations. We also cover Portsmouth, around 14 miles from Langrish.

Local landmarks in Langrish
We work on buildings around The Petersfield School. The closest station to Langrish is Petersfield station, about 2.3 miles east of the centre. A little further out are Clanfield Earthwork (4.3 miles south) and Bear Museum (2.7 miles east). Green spaces nearby include Shutts Copse and Pidham Hill.
Maintenance after handover
Cleaning and maintenance staff play a part too. Pass these on to them:
- Brief every trade that openings they make must be sealed
- File the specified details where the next contractor can find them
- Ask the designer to confirm details early on refits
- Keep general-purpose fillers away from compartment walls
Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.
What happens if it’s left?
The longer openings stay, the more there tend to be: every new cable or pipe adds another. Keeping on top of it after each round of works keeps the job small and avoids a much larger catch-up later. Converted and older buildings near places like Langrish tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: 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.

How the job changes by surface
Metal pipes
Sealant details often cover copper and steel pipework. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on.
Plastic pipes
Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.

Should maintenance staff do it?
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
How a job runs
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Langrish are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- First we go through the drawings, schedule or specification for the seals.
- 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.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Before we start on site
- Send any specification or drawings in advance
- Agree which areas must stay open
- For older buildings, check the asbestos register before work

FAQs: Langrish
Is hospital work, at somewhere like Petersfield Hospital, something you do?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What happens to BS 476 references for fire stopping in Langrish?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
How long does a typical visit take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
How long before the joints can be used?
We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, with one point of contact.
