When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Construction that lacks the fire resistance the seal relies on
  • Deciding what a wall or floor needs, which belongs to the designer
  • Reviewing a building’s overall fire safety

If you are not sure, just ring 01277 525 020 or email the details over and we will give you a straight answer before you book.

Where we work in Stodmarsh

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

Fire stopping in Stodmarsh

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. A rating such as EI 60 only holds when the product is installed as it was tested. So our job is to reproduce that arrangement faithfully. We work on cable penetrations, service gaps in risers and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are seals that don’t match their tested detail and penetration schedules that need working through. Whoever orders the work in Stodmarsh, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Rural conversions around Stodmarsh can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Service penetrations in Stodmarsh buildings

Stodmarsh lies roughly 57 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. 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.

For a hospital such as St Martins Hospital, 3.6 miles to the south-west of Stodmarsh, penetration sealing is normally phased ward by ward, with infection-control rules agreed first. Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. At a university such as Canterbury Christ Church University, which lies south-west of Stodmarsh, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Stodmarsh is about 5 miles east of Canterbury, in Kent. Looking for fire stopping in Stodmarsh? We can help, as we do across Kent. 931 places across Kent fall within our area, including Stodmarsh. Sites around London have their own page, roughly 57 miles from Stodmarsh.

Common questions from Stodmarsh clients

How does the move away from BS 476 affect penetration seals in Stodmarsh?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is Stodmarsh too small for you to travel to?

Not at all. Stodmarsh is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Commercial clients in Stodmarsh

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Different surfaces, different methods

Masonry and concrete

Many seals are made in blockwork, brickwork or concrete slabs. Dust and loose debris are cleared out of the opening, with backing added if the detail requires it.

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables, so we check before sealing.

Keeping the joints sound

Regular inspection catches problems early. In particular:

  • Flag new cables with no seal around them
  • Have penetrations checked while they can still be seen
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Keep product data and details in the fire safety file

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.

Our process

Working in a building that stays open takes some planning. We sign and contain the area we are in, keep walkways clear and work section by section so the rest of the building stays in use. For work around Stodmarsh, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  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. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Confirm the product named in the specification
  • Agree which areas must stay open
  • Send your site hours and access windows

Getting a fixed quote

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or email a schedule or drawings.

Why act early in Stodmarsh

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first. One visit to deal with every failing joint makes more sense than several trips to a place like Stodmarsh. Photos of every joint help us quote for the whole job.

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
