Compartments and services around Newbridge
For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.
Hospital estates such as Tatchbury Mount Hospital (to the east of Newbridge) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Where a unit on an estate such as Mortimer Trading Estate (1.7 miles north-east of Newbridge), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. Hotels like The Bartley Lodge Hotel, 1.4 miles to the south of Newbridge, are refurbished in phases, and each phase can open up compartment walls.

How we handle fire stopping in Newbridge
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. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and cable penetrations, and the usual reasons a site gets in touch are openings left by services added after handover and builders’ foam or ordinary silicone in compartment walls. Whoever orders the work in Newbridge, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller places such as Newbridge still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Cost factors for service penetrations
Sealant work doesn’t have a standard rate, because every site is different. What we take into account:
- Which sealant the job calls for
- Location, for remote and island sites
- How accessible the joints are
- The total length or number of joints
Pricing service penetrations depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.
Before you send an enquiry
There’s no need for a formal survey. A few details are enough to get going:
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours
- Whether an asbestos survey exists
- Where the site is, with the postcode
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call 01277 525 020 or email a schedule or drawings.
Looking after the joints
Regular inspection catches problems early. Specifically:
- Check with the data sheet before painting over fire sealant
- Look above ceilings when tiles are lifted for other jobs
- Record which product was used where
- Settle who seals which penetrations at the start of a project
Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open, not months later.

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Why act early in Newbridge
Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. Older rural buildings around Newbridge move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Questions about Newbridge
How does the move away from BS 476 affect penetration seals in Newbridge?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to 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 Tatchbury Mount Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a quote.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, with one point of contact across South East England, Greater London and Scotland.
What sealant work can’t fix
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Plastic pipes whose detail calls for a collar or wrap
- Writing the fire-stopping specification
- Fire doors, dampers or other fire safety equipment
If in doubt, phone 01277 525 020 or email us and we’ll say what we think.
Joints and surfaces we work on
- Joints between fire-resisting walls and floors
- Linear gaps at wall heads
- Service gaps in risers
- Cable penetrations
- Pipe penetrations
- Small duct penetrations where the tested detail allows
Diagnose, treat, sign off
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Newbridge, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- 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.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Tell us your opening times and when work is allowed
- Clear stock, furniture or equipment away from the joints
- Send asbestos survey details if the building is pre-2000
Ask for a quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
