How we handle fire stopping in Petworth

Facilities managers in Petworth 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 using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you’re dealing with open linear gaps along the top of fire-resisting walls and old intumescent sealant that has split away, we can put it right, on pipe penetrations, service gaps in risers and cable penetrations alike. Whether you call it commercial sealant work, mastic application or joint sealing, in Petworth it comes down to the same thing: the right product in a properly prepared joint.

Barn and farm-building conversions near places like Petworth often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

What the job involves on each surface

Plastic pipes

Waste and drainage pipes through floors are a frequent case. Whether sealant alone is acceptable depends entirely on the tested detail.

Linear joints

Linear joints run along the head of a wall, at a slab edge or between two fire-resisting elements. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers, and we work within it.

Common problems we fix in Petworth

Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. It may look closed, but it has no tested fire performance in that position.

Clients normally get in touch after noticing something like this:

  • Seals that don’t match their tested detail
  • Snag lists that include open service penetrations
  • Fire sealant pulled out of the opening
  • Damaged fire seals in risers and voids

Hotels such as The Angel Hotel (to the north-east of Petworth) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Questions to ask before you appoint anyone

From enquiry to sign-off

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 the job ends with a walk round and sign-off. Smaller jobs around Petworth can be grouped with others nearby. A fixed quote is given before anything starts.

  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. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Your questions answered

Will you take on work at estates like Hampers Common Industrial Estate, close to Petworth?

Yes. We cover Petworth and the area around it, including industrial estates, business parks and retail parks such as Hampers Common Industrial Estate. To start, just phone 01277 525 020 or email the details over with the unit, the joints involved and your access times.

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

Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.

Can you send site paperwork?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

When is resealing likely to be due?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

Are you insured?

Yes. We’re fully insured, including public liability cover.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Why deal with it now?

Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Around Petworth, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Aftercare for building managers

A few simple habits keep the new joints working:

  • File the specified details where the next contractor can find them
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask which product is in place before decorating
  • Don’t let anyone top up a fire seal with the wrong product

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.
