Fire stopping for Great Chart sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Commercial clients in Great Chart

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Great Chart can sit alongside others in a wider programme across Kent.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

How we handle fire stopping in Great Chart

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it using the product and detail it sets out. Where there isn’t one, the designer or fire engineer needs to set one first. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are fire stopping installed outside its tested range and service penetrations left open after M&E works. One point of contact handles commercial sealant work in Great Chart from the first photographs to the final walk-round, for single jobs and planned programmes alike.

A job near Great Chart is usually planned around one visit, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

From enquiry to sign-off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Smaller jobs around Great Chart can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Before we start on site

  • Have the specification and drawings to hand
  • Warn occupants and staff about the work
  • Tell us which areas need to stay in use

Advice

Quoting for work in Great Chart

These are the things that shape the price:

  • The product specified
  • The site’s rules and procedures
  • Location, for remote and island sites
  • Phasing around occupants

Pricing service penetrations depends on quantities, condition and access, and any specification that applies. Call for a quote.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • How the joints are reached, and at what height
  • Your programme or deadline
  • Photos of the joints, close up and from further back
  • The postcode of the building

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 photographs and a few notes.

Questions about Great Chart

Is a smaller place like Great Chart outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can work at a site such as Ashford College fit around teaching?

Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Can you seal any opening with fire-rated sealant?

No. A sealant’s evidence covers set services, gaps and wall or floor types. Outside that, a different product is needed, as set out by the designer.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you design or specify fire stopping?

No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Why act early in Great Chart

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down and each detail can be checked as we go. Around Great Chart, it’s better to renew all the failing joints at once. Send photos of each area and we’ll quote for the lot.

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.

Signs you need fire stopping in Great Chart

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

What tends to prompt an enquiry:

  • Old intumescent sealant that has split away
  • Penetration schedules that need working through
  • Non-fire-rated filler around services
  • Unsealed penetrations discovered above suspended ceilings

For a unit at a centre such as County Square, 1.6 miles to the east of Great Chart, penetration seals are worth checking after each shop fit.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • How they’ll work around occupants
  • How they handle RAMS and site documents
  • Whether old or failed sealant will be cut out, not overlaid

Our contractor checklist

How the job changes by surface

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, with backing added if the detail requires it.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, but many need a collar or wrap. We check the pipe material and diameter against the detail before we start.
