Fire stopping across Rayleigh

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

Leave it or put it right?

Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. Many buildings in towns like Rayleigh have been extended or altered, and joints where old meets new tend to fail first. Renewing them before water gets in protects the fabric.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site requirements come into it too.

What you get with us

  • Fully insured
  • 12 months’ guarantee on every job
  • CSCS-carded applicators
  • CHAS accredited contractor

Fire stopping for commercial buildings in Rayleigh

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4 and the results are classified to BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. If you are dealing with snag lists that include open service penetrations and openings left by services added after handover, we can help. A single leaking joint is often how a building in Rayleigh first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Older buildings in towns like Rayleigh have often been rewired and replumbed several times, and each change can leave unsealed holes in walls and floors. Our applicators follow the product’s published detail for that wall or floor whenever fire-rated sealant is the chosen seal.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. Most work in Rayleigh is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.

  1. The specification and schedule come first, so we know which details apply.
  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 so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

What we need from you

  • Let us know about inductions and permits
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Advice

What we are called out for in Rayleigh

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Things that typically lead to an enquiry:

  • Fire-rated sealant that has cracked or shrunk back
  • Unsealed openings around new pipes and cables
  • Head-of-wall gaps with no fire seal
  • Non-fire-rated filler around services

Wherever services are added at a hospital such as Chartwell Private Hospital, 3.2 miles south-east of Rayleigh, the compartment line has to be made good with the specified product.

What to look for in a quote

  • Their public liability cover
  • Will failed sealant be removed rather than covered?
  • Is the sealant right for the movement and the substrate?
  • How the joint faces will be prepared and primed

Our contractor checklist

Maintenance after handover

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Put resealing into every M&E and fit-out package
  • File the specified details where the next contractor can find them
  • Get seals inspected before ceilings and boxing close
  • Don’t let anyone top up a fire seal with the wrong product

Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way unless the designer specifies otherwise.

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 instead of being left for someone else.

Where services cross fire walls in Rayleigh

A number of hotels sit less than 2 miles from Rayleigh. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. At about 31 miles from central London, Rayleigh is within reach of the capital. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Industrial units on estates such as Imperial Park Industrial estate, 0.9 miles to the north of Rayleigh, often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal. Halls and meeting rooms at places like Church of Holy Trinity sometimes gain new services, and any compartment wall crossed needs the specified seal.

Rayleigh is about 5 miles north-west of Southend-on-Sea, in Essex. Across the SS6 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

We take on service penetrations across the SS6 and SS7 postcode area, whatever the building. Streets here include Station Road, High Street and London Road, and sites on any of them can send details for a fixed quote. Rayleigh sits on or close to the A127 and A129, useful when we plan access and materials.

Common questions from Rayleigh clients

Can work at a site such as South Essex College Stephenson Road Campus fit around teaching?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you seal around new services in a hotel near Rayleigh?

Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Are you CHAS accredited?

Yes. We’re CHAS accredited and a Constructionline member.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Cost factors for service penetrations

A fixed quote reflects the actual work. It allows for:

  • Quantities, in metres or numbers
  • Site requirements such as inductions and permits
  • Which sealant the job calls for
  • Removal of failed or old sealant

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • Any dates the work must fit around
  • Whether the building will be occupied during the work

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

When something else is needed

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

  • Walls or floors that aren’t fire-resisting to begin with
  • Deciding what a wall or floor needs, which belongs to the designer
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly.

What we seal

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