Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For work around Newtown, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- The specification and schedule come first, so we know which details apply.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- We tell you about openings that need a different product.
What we need from you
- Move anything stored against the joints
- Point out any areas we must not close
- Flag any permit to work we’ll need

Advice
Fire stopping in Newtown
For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings and the specified product data. Tell us what records you need and we will confirm with the quote. If you’re dealing with hidden openings found during inspections and open linear gaps along the top of fire-resisting walls, we can put it right, whatever the surface.

For a smaller site near Newtown, 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.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Leave it or put it right?
A seal that doesn’t match its tested detail gives false comfort. The fix is to remove it and reinstall to the detail. Around Newtown, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Questions about Newtown
Is Newtown too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
Is a hospital such as St Mary's Hospital somewhere you can work?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
When can the area be used after sealing?
The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.
Can you seal any opening with fire-rated sealant?
No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed, specified by your designer.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Surface by surface
Linear joints
Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Penetration seals near Newtown
For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
In a building such as Holy Spirit Church, any service penetration through a fire-resisting wall should be sealed to the specified detail. Office fit-outs on sites such as Porchfield Business Park (less than half a mile east of Newtown) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it. Hospital estates such as St Mary's Hospital, 4 miles east of Newtown, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.
Newtown is about 4 miles west of Newport, in the Isle of Wight. Newtown sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Newtown is one of 125 places in the Isle of Wight on our list. For work in that direction, see our Southampton page, about 14 miles away.
Work on service penetrations is covered throughout PO30, whatever the building. Sites close to Newtown are covered too, including Locksgreen (1 mile east), Porchfield (1 mile north-east), Great Thorness (2 miles north-east), Forest Side (3 miles east) and Rew Street (4 miles north-east).

Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Include service cupboards in routine inspections
- Agree the fire-stopping specification before services go in
- Treat an open penetration as a priority repair
- Check with the data sheet before painting over fire sealant
After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.
Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.
