Fire stopping for businesses in Great Burstead

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How we handle fire stopping in Great Burstead

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. Reproducing the tested arrangement on site is the part we take care of. If you have fire-rated sealant that has cracked or shrunk back and snag lists that include open service penetrations, we can help. For commercial sealant work in Great Burstead, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Rural conversions around Great Burstead 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.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, ring 01277 525 020 or email a schedule or drawings and we will arrange a return visit.

Why deal with it now?

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. Around Great Burstead, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The price depends on how many linear metres there are, how much old material needs removing and the access. Call for a quote when you are ready.

Why appoint us

  • Commercial sealant work since 2005
  • Joints cleaned back to sound surfaces
  • One contact handling all your sites
  • 12-month guarantee on workmanship

What affects the price in Great Burstead

What shapes the price:

  • Induction, permit and paperwork requirements
  • The size and state of each joint
  • Any access equipment needed
  • Removal of failed or old sealant

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • Any dates the work must fit around
  • Asbestos survey details if the building is older
  • What the building is and how it’s used
  • Approximate linear metres or a joint schedule

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Signing off or certifying a building’s fire stopping
  • Fire doors, dampers or other fire safety equipment
  • Large openings beyond what any sealant detail covers

If in doubt, phone 01277 525 020 or send photos by email and we’ll say what we think.

Where we work in Great Burstead

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

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For a building around Great Burstead, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Point out parking and an unloading spot
  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints

Great Burstead: questions and answers

Will you take on work at estates like Pipps Hill Industrial Estate, close to Great Burstead?

Yes. Estates, retail parks and business parks around Great Burstead, Pipps Hill Industrial Estate among them, are all within reach. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Is a hospital such as Mayflower Community Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.

Will you sign off the seals for us?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

What will the job cost?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or send details through our quote form.

When to call us in Great Burstead

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.

Things that usually lead to an enquiry:

  • Old intumescent sealant that has split away
  • Openings found when ceilings come down for a refit
  • Builders’ foam or ordinary silicone in compartment walls
  • Seals disturbed by maintenance and left open

On estates like Pipps Hill Industrial Estate, which lies south of Great Burstead, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Before you book anyone

  • Is the sealant right for the movement and the substrate?
  • Whether old or failed sealant will be cut out, not overlaid
  • How they handle RAMS and site documents
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Compartment walls and floors in Great Burstead

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. Either way, we install the specified product to its tested detail. At about 24 miles from central London, Great Burstead is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.

In a building such as Church of St Mary Magdalene, any service penetration through a fire-resisting wall should be sealed to the specified detail. Hospital estates such as Mayflower Community Hospital, 2.1 miles to the north-west of Great Burstead, are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Ask which product is in place before decorating
  • File the specified details where the next contractor can find them
  • Treat an open penetration as a priority repair
  • Foam or ordinary sealant is never a fire-seal repair

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

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