Need fire stopping in Rotherbridge?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Surface by surface

Metal pipes

Metal pipes conduct heat, so their details often call for extra measures along the pipe, and the tested detail may ask for insulation beyond the wall. If the detail needs something beyond sealant, we tell you.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed, and we work within it.

Fire stopping in Rotherbridge

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. If you’re dealing with improvised or mixed-product fire seals and old intumescent sealant that has split away, we can put it right, on linear gaps at wall heads, service gaps in risers and joints between fire-resisting walls and floors alike. Whoever orders the work in Rotherbridge, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural conversions around Rotherbridge can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Our process

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For work around Rotherbridge, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Preparing the site

  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance

Request a quote

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Advice

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Check risers and ceiling voids after each round of works
  • Have penetrations checked while they can still be seen
  • Keep product data and details in the fire safety file

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

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.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Rotherbridge can form part of a wider programme across West Sussex.

FAQs: Rotherbridge

Can you seal penetrations in a hotel in Rotherbridge after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Can work in a care setting near Rotherbridge go ahead while residents are there?

Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.

Is Rotherbridge in your area?

Yes. Rotherbridge is in our area. To discuss a job, ring 01277 525 020 or email a schedule or drawings.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How do we ask for a quote?

The quote form is the simplest route, though you can also phone 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

How do you choose the sealant?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Compartment walls and floors in Rotherbridge

Rotherbridge lies roughly 43 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 area within 2 miles of Rotherbridge holds a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Hotels such as The Angel Hotel (to the north-east of Rotherbridge) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Where a unit on an estate such as Hampers Common Industrial Estate, which lies north-east of Rotherbridge, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

What we’re called out for in Rotherbridge

When a seal departs from its tested detail, the evidence no longer covers it. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are the usual culprits.

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

  • Expanding foam used as fire stopping
  • Penetration schedules that need working through
  • Fire seals cut back for extra cables and never reinstated
  • Openings found when ceilings come down for a refit

Schools such as Petworth Cof E Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

What your quote should include

  • What level of public liability insurance do they hold?
  • Are they CHAS accredited or on Constructionline?
  • Whether old or failed sealant will be cut out, not overlaid
  • How they handle RAMS and site documents

Our contractor checklist

What happens if it’s left?

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. One visit to deal with every failing joint makes more sense than several trips to a place like Rotherbridge. Send photos of each area and we will quote for the lot.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
