Fire stopping across Blue Town

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Leave it or put it right?

An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Fire stopping in Blue Town

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance. The enquiries we see most involve hidden openings found during inspections and damaged fire seals in risers and voids, across joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and linear gaps at wall heads. A single leaking joint is often how a building in Blue Town first comes to us: we look at the rest while we are there and tell you what we find.

Around Blue Town, penetration and linear seals tend to be one-building jobs. With the specification and photographs of the gaps, we can give a fixed quote and bring the right products.

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

From enquiry to sign-off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If neighbouring businesses or buildings around Blue Town need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open
  • Let us know about inductions and permits

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

Surface by surface

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail.

How the quote is worked out

What shapes the price:

  • The product specified
  • The size and state of each joint
  • Induction, permit and paperwork requirements
  • Whether the work must be split into stages

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.

What we need to price the job

There’s no need for a formal survey. A few details are enough to get going:

  • Anything awkward about access or site hours
  • The site address and postcode
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. If you have questions first, call the office on 01277 525 020 or email drawings and photos.

Aftercare for building managers

For the best life from the joints:

  • Brief every trade that openings they make must be sealed
  • Foam or ordinary sealant is never a fire-seal repair
  • Keep product data and details in the fire safety file
  • Agree the fire-stopping specification before services go in

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original unless the designer specifies otherwise.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

Where services cross fire walls in Blue Town

Blue Town lies roughly 37 miles out from central London. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls, and the gaps need sealing with the specified product. The area within 2 miles of Blue Town holds a number of hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

For a unit at a site such as Neats Court Retail Park, 2.2 miles to the south of Blue Town, any new service through a fire-resisting wall should be sealed to the tested detail. Wherever services are added at a hospital such as Sheppey Community Hospital (2.6 miles south-east of Blue Town) the compartment line has to be made good with the specified product.

Blue Town is about 3 miles north-west of Minster, in Kent. Looking for fire stopping in Blue Town? We can help. Across Kent, 931 places are covered, including Blue Town. For work in that direction, see our London page, about 37 miles away.

What we are called out for in Blue Town

Openings in fire-resisting walls typically appear when services are added or changed. 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.

Things that usually lead to an enquiry:

  • Builders’ foam or ordinary silicone in compartment walls
  • Seals that don’t match their tested detail
  • Penetration schedules that need working through
  • Fire-rated sealant that has cracked or shrunk back

Colleges such as Sheppey College (less than half a mile east of Blue Town) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

How to choose a sealant contractor

Your questions answered

Does your area include sites such as Neats Court Retail Park, near Blue Town?

Yes. Our area takes in Blue Town and its surroundings, with estates and business parks such as Neats Court Retail Park included. A few photos and the unit address let us price the work.

What does the BS 476 change mean for fire-rated sealant in Blue Town?

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.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

How do I request a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
