How we handle fire stopping in Ashburton
Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you have damaged fire seals in risers and voids and expanding foam used as fire stopping, we can help, whatever the surface. Most enquiries from Ashburton start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. If sealant is the specified product we fit it to its tested detail, and if the detail needs something else, you will hear it from us.
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.

General trades versus a specialist
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What affects the price in Ashburton
A fixed quote reflects the actual work. It takes account of:
- How much existing material needs removing
- The size and state of each joint
- The site’s rules and procedures
- Location, for remote and island sites
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 will put a fixed figure on it.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- The asbestos register, for older buildings
- Anything awkward about access or site hours
- The site address and postcode
- Approximate linear metres or a joint schedule
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or email the details over to discuss it first.
Signs you need fire stopping in Ashburton
On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in and later need putting right.
Most enquiries start with one or more of the following:
- Hidden openings found during inspections
- Head-of-wall gaps with no fire seal
- Improvised or mixed-product fire seals
- Fire seals cut back for extra cables and never reinstated
At a healthcare site like Shirley Oaks Hospital (0.6 miles south-east of Ashburton), new services through compartment walls are a constant, and each needs the specified seal.
What to look for in a quote
- How joint depth will be controlled
- Which product they’ll use, and why it suits the joint
- Are they CHAS accredited or on Constructionline?
- Do they follow the manufacturer’s priming guidance?
Aftercare for building managers
Problems stay small when the joints are checked regularly. Specifically:
- Report damaged or disturbed seals as soon as they’re spotted
- Look above ceilings when tiles are lifted for other jobs
- Arrange inspection before areas are covered up
- Check with the data sheet before painting over fire sealant
Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail, by someone who knows the system.
Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.
Our process
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. In Ashburton, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Improvised fillers and failed sealant are removed.
- 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.
Preparing the site
- Make sure the joints can be reached
- Share your working hours and any access restrictions
- Have the specification and drawings to hand

Advice
Fire-rated sealing for Ashburton buildings
Ashburton has five care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Fire stopping of openings and penetrations in England falls under Approved Document B. 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. What we install is set by the specification, and it goes in to the tested detail.
For a unit at a centre such as Whitgift Centre, 1.6 miles south-west of Ashburton, penetration seals are worth checking after each shop fit. Workshops and IT rooms at colleges like Spurgeon's College (1.5 miles north-west of Ashburton) are re-serviced often, leaving penetrations to seal.
Ashburton is about 6 miles south of New Cross, in Greater London. We cover Ashburton, with the same fixed quotes and 12-month guarantee as everywhere else. Our Greater London coverage takes in 764 places, from busy centres to rural villages. Sites around London have their own page, roughly 8 miles from Ashburton.
Postcode districts covered here: CR0, SE25 and CR9 for service penetrations. If your site is on Long Lane, Tudor Road and Coe Avenue or close by, we can quote for service penetrations. Sites close to Ashburton are covered too, including Woodside (1 mile north), Addiscombe (1 mile south), Shirley Oaks (1 mile south-east), Monks Orchard (1 mile south-east) and Shirley (1 mile south-east). Further afield, our area takes in London (8 miles north), City of Westminster (9 miles north-west), Marylebone (10 miles north), Kensington (10 miles north-west), St Pancras (10 miles north) and Shoreditch (10 miles north).
Landmarks near Ashburton
We work on buildings around Oasis Academy Shirley Park, Ashburton Park and The Beehive pub and the streets around them. For rail, the closest station is Norwood Junction station, roughly 0.7 miles north-west. A little further out are National Psychosis Unit (1.7 miles east) and Whitgift Centre (1.6 miles south-west). For a walk, there’s Duppas Hill and Bramley Bank.
Why deal with it now?
It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Your questions answered
Will you work in a care home in Ashburton without moving residents out?
Yes. We agree rooms and times with the manager and work a few areas at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. Share the building’s contractor rules and we’ll work to them. The ULEZ covers the whole of Greater London, which we allow for
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Will you write the fire-stopping specification?
No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
Are you insured?
Yes. We’re fully insured, and the certificate can go with your quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or send photos by email. Include photographs or drawings if you have them.
