Fire stopping for commercial buildings in Trash Green
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. If you’re dealing with openings found when ceilings come down for a refit and penetration schedules that need working through, we can put it right, whatever the surface.

A job near Trash Green is typically planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Work we carry out in West Berkshire comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Fire stopping in Trash Green: the local picture
Central London is about 42 miles from Trash Green. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. A 2-mile radius around Trash Green takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.
Colleges such as Integration College (1.8 miles north of Trash Green) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. Campus buildings at universities such as University of Reading, 4.6 miles to the north-east of Trash Green, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Site staff or a sealant specialist?
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
FAQs: Trash Green
Can work at a site such as University of Reading fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work at a site such as Theale Lakes Business Park, by Trash Green?
Yes, sites like Theale Lakes Business Park are within our area, along with the rest of Trash Green. Send details of the unit and the work through our quote form for a quick quote.
Is Trash Green in your area?
Yes. We take on work across Trash Green, and the same phone number covers every area.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you seal any opening with fire-rated sealant?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we will tell you when that applies.
Is your workmanship covered by a guarantee?
Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.
Do the same rules apply to fire stopping in Scotland?
Our work covers Greater London, the South East and every Scottish council area. Scotland’s non-domestic Technical Handbook, clause 2.1.14, expects service penetrations to be fire stopped to at least the wall or floor’s fire resistance.
What sets the cost
What shapes the price:
- Travel to remote or island sites
- Joint width, depth and condition
- Which sealant the job calls for
- Whether the work must be split into stages
A quote for service penetrations depends on how many there are, their condition and the access. Call for a quote.

Good information means a firmer quote. When you get in touch, include:
- When you need the work done
- Specification clauses that apply
- The asbestos register, for older buildings

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.
On site: what to expect
At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Trash Green, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.
- 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.

Advice
Common problems we fix in Trash Green
Physical damage is another reason seals stop doing their job. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe.
Common reasons buildings call us in:
- Snag lists that include open service penetrations
- Fire seals cut back for extra cables and never reinstated
- Expanding foam used as fire stopping
- Service penetrations left open after M&E works
Large healthcare estates like Prospect Park Hospital (to the north-east of Trash Green) change their services often, so penetration seals are worth checking after M&E work.
Questions to ask before you book
- How they handle RAMS and site documents
- Will failed sealant be removed rather than covered?
- The named product and why it was chosen
- Can the work be phased to keep areas open?
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Fire risk assessments, a job for a competent assessor
- Large openings beyond what any sealant detail covers
- Walls or floors that aren’t fire-resisting to begin with
Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly.
What we seal
- Small duct penetrations where the tested detail allows
- Pipe penetrations
- Linear gaps at wall heads
- Cable penetrations
- Joints between fire-resisting walls and floors
- Service gaps in risers

Why act early in Trash Green
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Halls, stores and units around places like Trash Green may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Why appoint us
