About our fire stopping in Sevenoaks Weald

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on pipe penetrations, cable penetrations and small duct penetrations where the tested detail allows, and what we are called in for most is openings found when ceilings come down for a refit and fire-stopping items raised at inspection or handover. For commercial sealant work in Sevenoaks Weald, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Barn and farm-building conversions near places like Sevenoaks Weald often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Commercial clients in Sevenoaks Weald

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

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

Keeping the joints sound

After handover, these steps help:

  • Don’t let anyone top up a fire seal with the wrong product
  • Leave fire sealant to cure fully before covering it
  • Ask the designer to confirm details early on refits
  • Treat an open penetration as a priority repair

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail, by someone who knows the system.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.

Your questions answered

Is a smaller place like Sevenoaks Weald outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

What does the BS 476 change mean for fire-rated sealant in Sevenoaks Weald?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

How soon can the area be used again?

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

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

What do you charge?

There isn’t a price list, as every site differs. Send photographs or drawings and we’ll price it at a fixed figure.

Do you need to see the site first?

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

Do you need fire stopping in Sevenoaks Weald?

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Common reasons buildings call us in:

  • Fire sealant pulled out of the opening
  • Expanding foam used as fire stopping
  • Hidden openings found during inspections
  • Improvised or mixed-product fire seals

Schools such as Weald Community Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Questions to ask before you book

  • Health and safety accreditation such as CHAS
  • Proof of insurance
  • Will CSCS-carded applicators be on site?
  • How joint depth will be controlled

Cost factors for service penetrations

We price every job individually. The things that drive the figure:

  • The size and state of each joint
  • Specialist products, such as fire-rated or hygienic sealants
  • Quantities, in metres or numbers
  • The site’s rules and procedures

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • The product your specification calls for
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours
  • When you need the work done

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Sevenoaks Weald may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We read the specification, drawings or penetration schedule you send.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Flag any permit to work we will need
  • Tell us your opening times and when work is allowed
  • Send any specification or drawings in advance

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Advice

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Plastic pipes whose detail calls for a collar or wrap
  • Construction that lacks the fire resistance the seal relies on
  • Deciding what a wall or floor needs, which belongs to the designer

If in doubt, call 01277 525 020 or email the details over and we will say what we think.

Joints and surfaces we work on

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