Fire stopping for businesses in Bethersden

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Your questions answered

Do you design the fire stopping for buildings in Bethersden?

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.

Is Bethersden too small for you to travel to?

No. Places such as Bethersden are covered as much as the big towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Do you take on multi-site work?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

What hours do you work?

Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

About our fire stopping in Bethersden

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. We work on linear gaps at wall heads, cable penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are snag lists that include open service penetrations and openings left by services added after handover. One point of contact handles commercial sealant work in Bethersden from the first photos to the final walk-round, whether it’s one building or several.

Rural conversions around Bethersden 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, give us a call on 01277 525 020 or email drawings and photos and we will arrange a return visit.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Writing the fire-stopping specification
  • Fire risk assessments, a job for a competent assessor
  • Large openings beyond what any sealant detail covers

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly.

Where we work in Bethersden

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

Penetration seals near Bethersden

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. At about 45 miles from central London, Bethersden is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Halls and meeting rooms at places like Church of St Margaret sometimes gain new services, and any compartment wall crossed needs the specified seal. Schools such as Bethersden Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Bethersden is about 5 miles west of Ashford, in Kent. Anywhere in TN26, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Kent, 931 places are covered, Bethersden among them. Brighton is covered too, around 44 miles from Bethersden.

If you need fire stopping in TN26, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

We also cover Wissenden (1 mile north-west), Further Quarter (2 miles west), Chambers' Green (2 miles north), Maltman's Hill (2 miles north-west) and High Halden (3 miles south-west) for service penetrations. Bigger towns within reach include Maidstone (14 miles north-west), Ashford (5 miles east), Sittingbourne (15 miles north), Faversham (14 miles north-east), Hythe (15 miles east) and Davington (14 miles north-east).

Cost factors for service penetrations

Your fixed quote is built from the real scope. It takes account of:

  • Location, for remote and island sites
  • The product specified
  • How much existing material needs removing
  • Site requirements such as inductions and permits

A quote for service penetrations depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

Sending details for a quote

A few photographs plus some basic facts will normally do. Please tell us:

  • Approximate linear metres or a joint schedule
  • A wide shot and a close-up of the area
  • What the building is and how it’s used
  • Asbestos survey details if the building is older

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or use the quote form.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Bethersden can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  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.

What we need from you

  • Send your site hours and access windows
  • Share the asbestos register for older buildings
  • Tell us which areas need to stay in use

Looking after the joints

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

  • Ask which product is in place before decorating
  • File the specified details where the next contractor can find them
  • Have penetrations checked while they can still be seen
  • Ask the designer to confirm details early on refits

New services after handover are a common way fire stopping gets breached. A short check at the end of each job saves a long hunt later.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there.

Site staff or a sealant specialist?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

Surface by surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any outside it are raised with you.

Plastic pipes

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