Do you need fire stopping in Borden?

Openings in fire-resisting walls usually appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Things that normally lead to an enquiry:

  • Open linear gaps along the top of fire-resisting walls
  • Unsealed penetrations discovered above suspended ceilings
  • Fire stopping installed outside its tested range
  • Old intumescent sealant that has split away

Hotels like The Bull Hotel (to the east of Borden) are refurbished in phases, and each phase can open up compartment walls.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • How the joint faces will be prepared and primed
  • Whether old or failed sealant will be cut out, not overlaid

How to choose a sealant contractor

Fire stopping in Borden, done properly

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. We match each opening to that detail before any sealant goes in, and raise it with you if it falls outside. We work on joints between fire-resisting walls and floors, cable penetrations and pipe penetrations, and the usual reasons a site gets in touch are unsealed openings around new pipes and cables and old intumescent sealant that has split away. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Borden, that means joint design, primers and backing rod as standard.

Around smaller places like Borden, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

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

Our process

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For a building around Borden, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  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.

Before we start on site

  • Send your site hours and access windows
  • Flag any permit to work we will need

Why it’s worth doing now in Borden

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail. Older rural buildings around Borden move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote when you are ready.

Compartments and services around Borden

Borden lies roughly 36 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls. A 2-mile radius around Borden takes in several hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

On a site such as Kent Science Park, 1.6 miles south-east of Borden, every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. Workshops and IT rooms at colleges like Sittingbourne College (0.5 miles east of Borden) are re-serviced often, leaving penetrations to seal.

How the job changes by surface

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance along with any permits your site needs.

Drylining partitions

Drylined fire walls are tested in a particular build-up. We check that the product’s detail covers that partition type and board thickness.

FAQs: Borden

Can you seal penetrations in a hotel in Borden after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.

Can you work around term dates at a campus such as Canterbury Christ Church University?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Do you work in Borden?

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

When can you be on site?

We are 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.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

Aftercare for building managers

For the best life from the joints:

  • Leave fire sealant to cure fully before covering it
  • Settle who seals which penetrations at the start of a project
  • Put resealing into every M&E and fit-out package
  • Get seals inspected before ceilings and boxing close

During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

General trades versus a specialist

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
