Fire stopping for Aberchalder sites

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

How a job runs

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For work around Aberchalder, we aim for one trip, which is why we ask for photos and a full list first. External joints need a dry spell as well.

  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. 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.

Getting the site ready

  • Send any specification or drawings in advance
  • Make sure the joints can be reached
  • Share the asbestos register for older buildings

Fire stopping in Aberchalder, done properly

Facilities managers in Aberchalder often find open service penetrations when ceilings come down for other work. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you have openings left by services added after handover and expanding foam used as fire stopping, we can help. Whoever orders the work in Aberchalder, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places such as Aberchalder, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call the office on 01277 525 020 or email a schedule or drawings and we will come back to it.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions about Aberchalder

Is Aberchalder too small for you to travel to?

Not at all. Aberchalder is within our area. Our area covers all of Scotland, cities, towns and islands alike. We plan jobs in smaller places so return trips are kept to a minimum.

Do you design the fire stopping for buildings in Aberchalder?

No. Fire-stopping design and sign-off belong to the designer, principal 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.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Which sealant will you use?

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.

Do you have public liability insurance?

Yes. Our insurance certificate can be sent alongside the quote.

What do you charge?

There isn’t a price list, because every site is different. With photos or drawings, we can give you a fixed quote.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Different surfaces, different methods

Drylining partitions

Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers before sealing.

Small ducts

Small ductwork can sometimes be sealed with sealant where the tested detail includes it. Bigger ducts and fire-resisting ductwork are normally handled with other products and we flag that rather than guess.

Common problems we fix in Aberchalder

Openings in fire-resisting walls usually 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 can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.

What tends to prompt an enquiry:

  • Seals disturbed by maintenance and left open
  • Head-of-wall gaps with no fire seal
  • Fire-rated sealant that has cracked or shrunk back
  • Builders’ foam or ordinary silicone in compartment walls

Wherever the building is near Aberchalder, design and sign-off of fire stopping sit with the designer, fire engineer or building control; we install what has been specified.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • The named product and why it was chosen
  • How the existing material will be dealt with
  • How they’ll work around occupants

Choosing a commercial sealant contractor

What sealant work can’t fix

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Deciding what a wall or floor needs, which belongs to the designer
  • Walls or floors that aren’t fire-resisting to begin with
  • Large openings beyond what any sealant detail covers

If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Where we work in Aberchalder

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

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

Looking after the joints

For the best life from the joints:

  • Keep product data and details in the fire safety file
  • Ask which product is in place before decorating
  • Get seals inspected before ceilings and boxing close
  • Brief every trade that openings they make must be sealed

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, and it helps at inspections.
