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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
About our fire stopping in Roser's Cross
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on pipe penetrations, joints between fire-resisting walls and floors and service gaps in risers, and what we are called in for most is openings found when ceilings come down for a refit and damaged fire seals in risers and voids. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Roser's Cross, that means joint design, primers and backing rod as standard.
A job near Roser's Cross is usually planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.
A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or email us and we will come back to it.

Why act early in Roser's Cross
Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. One visit to deal with every failing joint makes more sense than several trips to a place like Roser's Cross. Photos of every joint help us quote for the whole job.
A quote for service penetrations depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Advice
Common problems we fix in Roser's Cross
Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is when untested combinations creep in and later need putting right.
Typical triggers for a call:
- Fire seals cut back for extra cables and never reinstated
- Openings left by services added after handover
- Fire-rated sealant that has cracked or shrunk back
- Improvised or mixed-product fire seals
Older community buildings such as The Parish Church of All Saints that have been rewired or given new heating can have service gaps through walls worth checking against the specification.
What your quote should include
- Whether their applicators hold CSCS cards
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will RAMS and insurance details be available?
- Their plan for phasing and protecting the area

What else we do in Roser's Cross
Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Keep general-purpose fillers away from compartment walls
- Flag new cables with no seal around them
- Agree the fire-stopping specification before services go in
- Get seals inspected before ceilings and boxing close
Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.
Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.

Where services cross fire walls in Roser's Cross
