Questions about Wareside
What happens to BS 476 references for fire stopping in Wareside?

How we handle fire stopping in Wareside
Facilities managers in Wareside often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on service gaps in risers, pipe penetrations and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are fire seals cut back for extra cables and never reinstated and expanding foam used as fire stopping. For commercial sealant work in Wareside, you deal with one contact from quote to sign-off, whether it’s one building or several.
Smaller places such as Wareside still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Work we carry out in Hertfordshire comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we’ll come back to it.

What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Fire risk assessments, a job for a competent assessor
- Deciding what a wall or floor needs, which belongs to the designer
- Gaps in walls that were never built as compartment walls
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.
Where we work in Wareside

Signs you need fire stopping in Wareside
Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position, so it has to come out.
Common reasons buildings call us in:
- Unsealed penetrations discovered above suspended ceilings
- Service penetrations left open after M&E works
- Fire sealant pulled out of the opening
- Open linear gaps along the top of fire-resisting walls
Holiday works at schools like Wareside Church of England Primary School often leave service openings to seal before pupils return.

Looking after the joints
Regular inspection catches problems early. Specifically:
- Have penetrations checked while they can still be seen
- Leave fire sealant to cure fully before covering it
- Brief every trade that openings they make must be sealed
- Settle who seals which penetrations at the start of a project
New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.
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.

How the job changes by surface
Plastic pipes
Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes, but many need a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.
Risers and ceiling voids
Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance, including keys, permits and any isolations.
Commercial clients in Wareside
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Wareside, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- 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.
- Unsuitable material is removed and the opening cleaned first.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Let building users know which areas are affected
- Share your working hours and any access restrictions
- Arrange parking or a loading space
