About our fire stopping in Newtown
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and service gaps in risers, and what we’re called in for most is openings left by services added after handover and unsealed penetrations discovered above suspended ceilings. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Newtown it comes down to the same thing: the right product in a properly prepared joint.
For a smaller site near Newtown, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
A 12-month guarantee applies to all our work. If an installation problem shows up, call 01277 525 020 or use the quote form and we’ll arrange a return visit.

Compartment walls and floors in Newtown
At about 60 miles from central London, Newtown is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
In a building such as Church of the Holy Trinity, any service penetration through a fire-resisting wall should be sealed to the specified detail. At a healthcare site like Knowle Hospital, which lies south-west of Newtown, new services through compartment walls are a constant, and each needs the specified seal.
Newtown is about 5 miles north-west of Waterlooville, in Hampshire. Our applicators travel to Newtown for work on service penetrations. 723 places across Hampshire fall within our area, Newtown among them. Our Portsmouth page has more on work in that area, about 8 miles away.
Work on service penetrations is covered throughout PO17, whatever the building. Among the streets we cover are Church Road, Hundred Acres Road and Ingoldfield Lane. We also cover Southend (1 mile north-east), Soberton Heath (1 mile north), Hoe Gate (1 mile east), Hipley (1 mile south-east) and Woodend (1 mile north-west). A short drive away, we cover Winchester (13 miles north-west), Gosport (8 miles south), Havant (7 miles south-east), Eastleigh (10 miles west), Fareham (5 miles south-west) and Horndean (5 miles east).

Common problems we fix in Newtown
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
Clients normally get in touch after noticing something like this:
- Fire-rated sealant that has cracked or shrunk back
- Openings found when ceilings come down for a refit
- Damaged fire seals in risers and voids
- Builders’ foam or ordinary silicone in compartment walls
Office fit-outs on sites such as Waltham Business Park (to the north-west of Newtown) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.
What your quote should include
- The named product and why it was chosen
- Their public liability cover
- How the existing material will be dealt with
- How they’ll work around occupants
Leave it or put it right?
Open penetrations multiply: each new service adds to the list. Keeping on top of it after each round of works keeps the job small, rather than turning into a full building survey and reseal. One visit to deal with every failing joint makes more sense than several trips to a place like Newtown. Send photos of each area and we’ll quote for the lot.
We don’t publish prices, since every building and every scope is different. Call for a quote.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Get seals inspected before ceilings and boxing close
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Leave fire sealant to cure fully before covering it
- Include service cupboards in routine inspections
Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.
A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

What else we do in Newtown
Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. For a building around Newtown, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We read the specification, drawings or penetration schedule you send 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.
- If an opening needs something other than sealant, we tell you instead of improvising.
Getting the site ready
- Send your site hours and access windows
- Make sure the joints can be reached
- Share the asbestos register for older buildings

Questions we’re asked in Newtown
Do you cover business parks and estates near Newtown, such as Waltham Business Park?
Yes, sites like Waltham Business Park are within our area, along with the rest of Newtown. Send details of the unit and the work through our quote form for a quick quote.
Can you work on a hospital site such as Knowle Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
How many days will you need on site?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
How long will the new sealant last?
Nobody can honestly give a figure in years, 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.
Are you members of a third-party fire-stopping installer scheme?
No. We are not members of a third-party fire-stopping installer scheme. We are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded. Where a client or main contractor requires a scheme member, we’ll say so straight away rather than waste your time.
Can you seal any opening with fire-rated sealant?
No. Sealant is the right product only where the tested detail says so. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards.
What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Construction that lacks the fire resistance the seal relies on
- Signing off or certifying a building’s fire stopping
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.
Surfaces we seal
- Linear gaps at wall heads
- Service gaps in risers
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Cable penetrations
- Pipe penetrations
