Common problems we fix in Clachamish

Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.

Typical triggers for a call:

  • Openings left by services added after handover
  • Damaged fire seals in risers and voids
  • Improvised or mixed-product fire seals
  • Fire-stopping items raised at inspection or handover

For buildings in and around Clachamish, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Choosing a commercial sealant contractor

Fire stopping in Clachamish, done properly

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We hold no third-party fire-stopping installer certificate, and we won’t pretend otherwise. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. Most enquiries involve damaged fire seals in risers and voids and service penetrations left open after M&E works, on linear gaps at wall heads, cable penetrations and service gaps in risers. Most enquiries from Clachamish start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In smaller Scottish places like Clachamish, buildings with fire-resisting walls typically include schools, care homes, hotels and health centres. Those penetrations are closed with the product the specification names, built up as tested.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we will come back to it.

Commercial clients in Clachamish

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

How the job changes by surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Some intumescent sealants are tested on smaller plastic pipes. We check the pipe material and diameter against the detail before we start.

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.

How a job runs

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Tell us who will meet us and how to get in at your building near Clachamish. That goes into the plan alongside the quote.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  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. 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.

Getting the site ready

  • Explain the parking and delivery arrangements
  • Tell us your opening times and when work is allowed
  • Confirm the product named in the specification

Advice

Looking after the joints

For the best life from the joints:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep product data and details in the fire safety file
  • Don’t let anyone top up a fire seal with the wrong product
  • Settle who seals which penetrations at the start of a project

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

On fit-outs, get the fire-stopping specification agreed before the services go in. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Fire-rated sealing for Clachamish buildings

Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, with products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

Around Clachamish, fire-stopping design belongs to the designer and building control; installation to the specification is our part.

Questions we are asked in Clachamish

Is Clachamish off your patch?

Not at all: smaller places are covered as well as towns. Every Scottish council area is within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Do you decide the fire-stopping details for buildings in Clachamish?

No, that sits with the designer, fire engineer or building control. We install fire-rated and intumescent sealant around service penetrations and linear gaps where it is specified, to the manufacturer’s tested detail.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.

Does the weather affect the work?

It can, for external work. 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.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What will the job cost?

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