Fire stopping across Chesser

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

How we handle fire stopping in Chesser

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, often unnoticed. We close the openings listed on your schedule, using the specified sealant and detail. Most enquiries involve seals disturbed by maintenance and left open and openings left by services added after handover, across pipe penetrations, joints between fire-resisting walls and floors and cable penetrations. Searching for sealant specialists in Chesser? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Large city estates in Scotland, from universities to hospitals and offices, are re-serviced constantly, and each new run of cable or pipe through a compartment wall needs sealing. New openings are closed with the specified fire-rated product, following its test evidence.

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

Aftercare for building managers

A few simple habits keep the new joints working:

  • Leave fire sealant to cure fully before covering it
  • Include service cupboards in routine inspections
  • Get seals inspected before ceilings and boxing close
  • File the specified details where the next contractor can find them

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, so check the product data first.

Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Construction that lacks the fire resistance the seal relies on
  • Reviewing a building’s overall fire safety
  • Large openings beyond what any sealant detail covers

If you are not sure, just ring 01277 525 020 or email drawings and photos and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Compartments and services around Chesser

In Scotland, clause 2.1.14 of the non-domestic Technical Handbook expects service penetrations to keep at least the fire resistance duration of the wall or floor, and products should be tested for their end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail. A good number of hotels sit less than 2 miles from Chesser. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal.

Shop fits on retail sites such as Edinburgh West Retail Park, less than half a mile north-east of Chesser, can bring new services through fire-resisting walls between units, to be sealed with the specified product. For a hotel such as Tynecastle Park Hotel, 1 mile to the north-east of Chesser, penetration seals are worth checking after any refit or services upgrade. For a hospital such as Royal Edinburgh Hospital, which lies east of Chesser, penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

Work for main contractors and building owners

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Chesser can sit alongside others in a wider programme.

On site: what to expect

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. City jobs in Chesser normally need parking and loading planned. Tenement closes, shared stairs and factor approvals may also be involved.

  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. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Send your site hours and access windows
  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000

Different surfaces, different methods

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Larger or fire-rated ductwork normally needs a different solution set by the designer.

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.

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.

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

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.

Do you work to architects’ specifications?

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