How we handle fire stopping in Dorney
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow. If you have seals that don’t match their tested detail and openings found when ceilings come down for a refit, we can put it right, whatever the surface. A single leaking joint is often how a building in Dorney first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Dorney, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the job changes by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest so we know it sits within the tested range, and any outside it are raised with you.
Risers and ceiling voids
Openings above suspended ceilings are easy to miss. We follow your schedule area by area and tell you about openings outside the list.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Building owners, agents and FMs in Dorney
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
How the quote is worked out
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Quantities, in metres or numbers
- How accessible the joints are
- Distance, for remote addresses
- The product specified
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Details that help us quote
Whether it’s one area or a whole building, the same details help:
- Any specification or named product
- The asbestos register, for older buildings
- Clear photographs of the problem areas
- Where the site is, with the postcode

Questions we are asked in Dorney
Is Dorney off your patch?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
What does the BS 476 change mean for fire-rated sealant in Dorney?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
What will the job cost?
There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.
How soon can the area be used again?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
What if there’s asbestos in the old mastic?
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.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Check with the data sheet before painting over fire sealant
- Record which product was used where
- Settle who seals which penetrations at the start of a project
- Keep general-purpose fillers away from compartment walls
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.
Service penetrations in Dorney buildings
Three care or nursing homes sit less than 2 miles from Dorney. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified. At about 24 miles from central London, Dorney is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.
Halls and meeting rooms at places like Church of St James sometimes gain new services, and any compartment wall crossed needs the specified seal. In a hotel such as Oakley Court Hotel, 1.1 miles to the south-west of Dorney, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Theatres, wards and plant rooms at sites like Upton Hospital (2.7 miles east of Dorney) all have compartment walls crossed by services.

From enquiry to sign-off
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Jobs in and around smaller places like Dorney are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- The specification and schedule come first, so we know which details apply.
- 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.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
What we need from you
- Make sure the joints can be reached
