Fire stopping in Redhill, done properly

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. We work on linear gaps at wall heads, pipe penetrations and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are fire-rated sealant that has cracked or shrunk back and openings left by services added after handover. A specialist sealant contractor works differently from a general builder: on jobs in Redhill, preparation and product choice get the time they need.

Towns the size of Redhill have plenty of buildings with compartment walls: schools, care homes, surgeries, offices and blocks of flats. New cabling or pipework through a fire-resisting wall leaves a gap that has to be made good with the specified product.

A 12-month guarantee applies to all our work. Should something we installed fail, ring 01277 525 020 or email a schedule or drawings and we will come back to it.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Settle who seals which penetrations at the start of a project
  • Flag new cables with no seal around them
  • Check with the data sheet before painting over fire sealant
  • Make fire stopping part of every scope that crosses a fire-resisting wall

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Fire stopping around Redhill: how the place shapes the job

Redhill has a number of hotels close by, all within 2 miles. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

Halls and meeting rooms at places like Saint Matthew's Church sometimes gain new services, and any compartment wall crossed needs the specified seal. At a college such as Reigate College, which lies west of Redhill, checking penetration seals after summer M&E works is good practice.

On site: what to expect

Diagnose, treat, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. In a town such as Redhill, most jobs are single buildings. Your photographs, drawings or a site visit come first, followed by a fixed quote.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Warn occupants and staff about the work
  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work

Advice

Leave it or put it right?

A seal that doesn’t match its tested detail gives false comfort. Correcting it means cutting it out and starting again with the specified product, and doing it once, properly, is cheaper. Many buildings in towns like Redhill have been extended or altered, and joints where old meets new tend to fail first. Resealing them early protects the building behind.

A quote for service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Common questions from Redhill clients

Do you seal service penetrations in hotels around Redhill?

Yes, where fire-rated sealant is the specified product. Each seal follows the tested detail, and rooms are done in turn.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Redhill?

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.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Fire risk assessments, a job for a competent assessor
  • Gaps in walls that were never built as compartment walls

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Small duct penetrations where the tested detail allows
  • Service gaps in risers
  • Linear gaps at wall heads
  • Cable penetrations
  • Pipe penetrations
  • Joints between fire-resisting walls and floors

When to call us in Redhill

A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.

Any of the following is a good reason to get the joints checked over:

  • Open linear gaps along the top of fire-resisting walls
  • Non-fire-rated filler around services
  • Snag lists that include open service penetrations
  • Fire seals cut back for extra cables and never reinstated

Tenant changes at parks like Kingsfield Business Centre (to the south-east of Redhill) bring new data and services, and openings through fire-resisting walls need the specified seal.

Questions to ask before you book

  • Will RAMS and insurance details be available?
