Need fire stopping in Lynsted?

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

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Gaps in walls that were never built as compartment walls
  • Reviewing a building’s overall fire safety
  • Deciding what a wall or floor needs, which belongs to the designer

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

Surfaces we seal

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

Fire stopping in Lynsted, done properly

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. Most enquiries involve seals that don’t match their tested detail and fire sealant pulled out of the opening, across joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and pipe penetrations. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Lynsted is the same: the right product in a properly prepared joint.

Smaller places such as Lynsted still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Work we carry out in Kent comes with a 12-month guarantee. Should something we installed fail, give us a call on 01277 525 020 or send photos by email and we’ll come back to it.

Commercial clients in Lynsted

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Lynsted can sit alongside others in a wider programme across Kent.

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Cost factors for service penetrations

Each job is priced on its own details. The main factors are:

  • Working within restricted access windows
  • Travel to remote or island sites
  • Induction, permit and paperwork requirements
  • Specialist products, such as fire-rated or hygienic sealants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

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

  • The product your specification calls for
  • How the joints are reached, and at what height
  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area

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

Fire-rated sealing for Lynsted buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 40 miles from Lynsted. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls; the gaps need the specified seal.

Halls and meeting rooms at places like Church of St Peter and St Paul sometimes gain new services, and any compartment wall crossed needs the specified seal. In a hotel such as Hempstead House Hotel, which lies north-west of Lynsted, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. For a building at a site such as Kent Science Park (2.7 miles west of Lynsted), a check of penetration seals after each fit-out is good practice.

Lynsted is about 3 miles south-east of Sittingbourne, in Kent. We cover Lynsted, with the same fixed quotes and 12-month guarantee as everywhere else. 931 places across Kent fall within our area, Lynsted among them. Sites around London have their own page, about 40 miles away.

Anyone looking for fire stopping in ME9 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

We also cover Bogle (1 mile north-east), Erriottwood (1 mile south), Bapchild (1 mile west), Newbury (1 mile south-west) and Radfield (1 mile north) for service penetrations.

After the work

A few simple habits keep the new joints working:

  • Include service cupboards in routine inspections
  • Ask the designer to confirm details early on refits
  • Treat an open penetration as a priority repair
  • Foam or ordinary sealant is never a fire-seal repair

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

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

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. For a building around Lynsted, 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 confirm the product and tested details named in the specification.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Send your site hours and access windows
  • For older buildings, check the asbestos register before work
  • Confirm the product named in the specification

Request a quote

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

Lynsted: questions and answers

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in Lynsted?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is a smaller place like Lynsted outside your area?

No. Places such as Lynsted are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

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.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs normally get a visit.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Why deal with it now?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme. Around Lynsted, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
