Fire stopping in Dorney Reach
The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. If you are dealing with penetration schedules that need working through and damaged fire seals in risers and voids, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Dorney Reach is the same: the right product in a properly prepared joint.
Rural conversions around Dorney Reach can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach, and the right detail can be checked at the time. Around Dorney Reach, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
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’ll have a fixed figure to work with.

Where services cross fire walls in Dorney Reach
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. Either way, we install the specified product to its tested detail. Dorney Reach lies roughly 25 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.
Tenant changes at centres like Bath Road Shopping Park, 2.1 miles to the north-east of Dorney Reach, often mean new services through walls between units. For a building such as Church of St James, new heating or data runs are the usual reason penetrations need sealing.

Common questions from Dorney Reach clients
Can work in a care setting near Dorney Reach go ahead while residents are there?
Yes. Care settings are planned area by area, at times agreed with the home. Any site rules, from signing in to infection control, are agreed before we start.
Do you work on fire-rated sealing in hotels in Dorney Reach?
Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do you guarantee your work?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

- Builders’ foam or ordinary silicone in compartment walls
- Unsealed openings around new pipes and cables

Our process
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For work around Dorney Reach, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We ask for the product and detail your designer has specified.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Mineral wool or other backing is fitted where required.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- Completed areas are checked with you, with the records agreed when we quoted.
What we need from you
- Tell us which areas need to stay in use
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements

When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Cost factors for service penetrations
A fixed quote reflects the actual work. It takes account of:
- How much existing material needs removing
- Any access equipment needed
- Working within restricted access windows
- Quantities, in metres or numbers
A quote for service penetrations depends on how many there are, their condition and the access. Call for a quote.
What to include in your enquiry
To price the job accurately, we need to understand the site. Send us:
- Rough lengths or quantities, or drawings if you have them

- Whether an asbestos survey exists
- Any dates the work must fit around
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 us if you’d rather talk the job through.
