Fire stopping in Cholsey
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. We work to the product’s tested detail for every seal rather than guesswork. Site teams most often ask us about improvised or mixed-product fire seals and fire sealant pulled out of the opening, on pipe penetrations, cable penetrations and joints between fire-resisting walls and floors. Looking for mastic applicators who cover Cholsey? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Fire-rated sealing in a place like Cholsey is usually a single building at a time. Send the specification, drawings or photos of the openings and we will quote to suit.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Leave it or put it right?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product, so it makes sense to get it right first time. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

FAQs: Cholsey
What happens to BS 476 references for fire stopping in Cholsey?
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. Our part doesn’t change: the specified product, to its tested detail.
Is a hospital such as Wallingford Community Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
What do you charge?
We don’t publish prices, because every site is different. Send photographs or drawings and we will price it at a fixed figure.
How soon can the area be used again?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What happens if old sealant might contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Service penetrations in Cholsey buildings
Fire stopping of openings and penetrations in England falls under 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. We install whatever has been specified, to the product’s tested detail. The 2 miles around Cholsey include two care or nursing homes. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product.
Schools such as Cholsey Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Hotels such as The Springs Hotel (1.4 miles east of Cholsey) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. On a hospital site such as Wallingford Community Hospital, which lies north-east of Cholsey, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.
Cholsey is about 5 miles south-east of Didcot, in Oxfordshire. We send applicators to Cholsey for service penetrations, handled exactly as we handle every other area. We work across 423 places in Oxfordshire, from busy centres to rural villages. For work in that direction, see our Reading page, about 11 miles away.
Work on service penetrations is covered throughout OX10. If your site is on Station Road, Church Road and Lapwing Lane or close by, we can quote for service penetrations. We also cover Winterbrook (1 mile north-east), North Stoke (1 mile east), Moulsford (1 mile south), South Stoke (2 miles south) and Mongewell (2 miles north-east). Nearby towns on our patch include Oxford (13 miles north), Didcot (5 miles north-west), Abingdon-on-Thames (9 miles north-west), Thame (14 miles north-east), Wantage (12 miles west) and Henley-on-Thames (11 miles east).

Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. What matters most for a job in Cholsey is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Foam, ordinary sealant and debris come out 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.
Before we start on site
- Send your site hours and access windows
- Send any specification or drawings in advance
- Tell us what induction or permit system the site runs

Quoting for work in Cholsey
We price every job individually. The main factors are:
- Quantities, in metres or numbers
- Access and working height
- Site requirements such as inductions and permits
- Travel to remote or island sites
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.
What to include in your enquiry
However big the job, the same details help:
- The type of building and who uses it
- Whether an asbestos survey exists
- A wide shot and a close-up of the area
- Where the site is, with the postcode
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or email the details over to discuss it first.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Agree the fire-stopping specification before services go in
- Leave fire sealant to cure fully before covering it
- Keep product data and details in the fire safety file
- Report damaged or disturbed seals as soon as they’re spotted
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
