About our fire stopping in Mottisfont
No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. We work on cable penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the usual reasons a site gets in touch are damaged fire seals in risers and voids and fire stopping installed outside its tested range. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Mottisfont is the same: the right product in a properly prepared joint.
For a smaller site near Mottisfont, we plan to do all the penetrations in one go, with the specification and photographs sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Penetration seals near Mottisfont
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. Mottisfont lies roughly 70 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.
At a healthcare site like Romsey Community Hospital (4 miles south-east of Mottisfont), new services through compartment walls are a constant, and each needs the specified seal. On a site such as Home Farm Business Centre (2.2 miles west of Mottisfont), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

What affects the price in Mottisfont

- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
- The size and state of each joint
- Site requirements such as inductions and permits
A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.
Before you send an enquiry
Diagnosis starts before we arrive. Tell us:
- What the building is and how it’s used
- Anything awkward about access or site hours
- Where the site is, with the postcode
- Whether an asbestos survey exists
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
When to bring in a specialist
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Mottisfont: questions and answers
What happens to BS 476 references for fire stopping in Mottisfont?
From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.
Would you work within a site like Romsey Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Mottisfont in your area?
Yes. Sites across Mottisfont are covered, and the same phone number covers every area.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.
What do you charge?
Every job gets its own fixed quote. To get one, ring 01277 525 020 or send photos by email.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Do you need fire stopping in Mottisfont?
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
These are often picked up first by site or facilities staff:
- Fire sealant pulled out of the opening
- Expanding foam used as fire stopping
- Seals disturbed by maintenance and left open
- Head-of-wall gaps with no fire seal
Older community buildings such as Church of St Andrew that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What your quote should include
- Their plan for phasing and protecting the area
- Their pre-qualification and accreditations
- The terms of the workmanship guarantee
- How the existing material will be dealt with
Maintenance after handover
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Keep product data and details in the fire safety file
- Get seals inspected before ceilings and boxing close
- Settle who seals which penetrations at the start of a project
- Check risers and ceiling voids after each round of works
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, and the data sheet says which.
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 instead of being left for someone else.

What else we do in Mottisfont
How the job changes by surface
Metal pipes
Heat travels along metal pipework. If the detail needs something beyond sealant, we tell you.
Risers and ceiling voids
Voids hide a lot of unsealed openings. We follow your schedule area by area, and note anything we find that isn’t on it.
Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Rural sites near Mottisfont may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- 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.
- We gun the sealant in to the specified depth around each service and tool it.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Getting the site ready
- Explain the parking and delivery arrangements
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use
