Fire stopping across Aveley

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. What matters most for a job in Aveley is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.

  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. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Flag any permit to work we will need
  • Explain the parking and delivery arrangements
  • Warn occupants and staff about the work

Advice

About our fire stopping in Aveley

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal rather than guesswork. Most enquiries involve seals disturbed by maintenance and left open and unsealed joints where partitions meet the slab, on cable penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in Aveley from the first photos to the final walk-round, for single jobs and planned programmes alike.

Fire-rated sealing in a place like Aveley is normally a single building at a time. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Settle who seals which penetrations at the start of a project
  • Get seals inspected before ceilings and boxing close
  • Brief every trade that openings they make must be sealed
  • Check with the data sheet before painting over fire sealant

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

What happens if it’s left?

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these and the building feels the difference. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.

Fire-rated sealing for Aveley buildings

In England, Approved Document B covers fire stopping of openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail. A number of hotels sit less than 2 miles from Aveley. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

For a hospital such as Joyce Green Hospital, 2.8 miles south-west of Aveley, penetration sealing is typically phased ward by ward, with infection-control rules agreed first. For an estates team at a campus like University of Greenwich, 4.2 miles south of Aveley, summer M&E works are normally followed by a round of penetration sealing. Older community buildings such as Church of St Michael that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Aveley is about 4 miles west of Grays, in Thurrock. We cover commercial sites throughout Aveley, for single jobs and planned programmes alike. Our Thurrock coverage takes in 27 places, large and small. We also cover London, some 15 miles away.

How the quote is worked out

Quotes vary with the job. Expect it to depend on:

  • Travel to remote or island sites
  • Which sealant the job calls for
  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits

Pricing service penetrations depends on quantities, condition and access. Ask us for a fixed quote.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them
  • The postcode of the building
  • The product your specification calls for

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

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 will confirm with the quote.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • Gaps in walls that were never built as compartment walls
  • Signing off or certifying a building’s fire stopping
  • Fire risk assessments, a job for a competent assessor

If in doubt, call the office on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Where we work in Aveley

Your questions answered

What happens to BS 476 references for fire stopping in Aveley?

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.

Is Aveley too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we will plan around them.

How do we ask for a quote?

You can use the quote form on this site; alternatively, phone 01277 525 020 or email the details over. Include photographs or drawings if you have them.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Is the work guaranteed?

Yes. Our workmanship is backed for 12 months.
