Fire stopping near Keills

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How we handle fire stopping in Keills

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you’re dealing with hidden openings found during inspections and penetration schedules that need working through, we can put it right. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Keills it comes down to the same thing: the right product in a properly prepared joint.

Travel to smaller places like Keills is planned so every penetration is sealed on one trip. Photos of the gaps, the services and the wall or floor type help us bring the right products.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Surface by surface

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 first.

Plastic pipes

Waste and drainage pipes through floors are a frequent case. The detail decides whether sealant alone is enough, and we won’t substitute it for a specified collar.

Questions we’re asked in Keills

How do the Scottish rules apply to fire-rated sealing in Keills?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

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

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.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Is your workmanship covered by a guarantee?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

What sets the cost

These are the things that shape the price:

  • Whether the work must be split into stages
  • Any access equipment needed
  • Site requirements such as inductions and permits
  • How much existing material needs removing

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

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

  • Access details, including height
  • A wide shot and a close-up of the area
  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them

For a fixed quote, give us a call on 01277 525 020 or use the quote form with the site address and an outline of the work. You can also send details through our quote form.

From enquiry to sign-off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Where we can, we combine work around Keills with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  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. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

What we’re called out for in Keills

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it.

It’s worth sending us details if you spot any of the following:

  • Openings left by services added after handover
  • Hidden openings found during inspections
  • Builders’ foam or ordinary silicone in compartment walls
  • Fire stopping installed outside its tested range

Around Keills, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

Comparing quotes

  • Whether old or failed sealant will be cut out, not overlaid
  • Their pre-qualification and accreditations
  • How joint depth will be controlled
  • Is the sealant right for the movement and the substrate?

Questions to ask before you appoint anyone

Where services cross fire walls in Keills

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, with proprietary products, intumescent ones included, tested for their end use. We install what’s specified, to the product’s tested detail.

Hotels such as Port Askaig Hotel, 1 mile to the north-east of Keills, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified.

Keills is in Argyll and Bute. Across the PA46 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 124 places in Argyll and Bute. We also cover Glasgow, around 72 miles from Keills.

Postcode districts covered here: PA46 for service penetrations. We also cover Port Askaig (1 mile north-east), Bunnahabhain (3 miles north), Craighouse (7 miles east), Bowmore (8 miles south-west) and Port Charlotte (12 miles south-west). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

Well-known places in the area include Finlaggan Castle (1.8 miles west). For a walk, there’s Loch Ballygrant and Beinn Dubh.

Looking after the joints

A few simple habits keep the new joints working:

  • Get seals inspected before ceilings and boxing close
  • Treat an open penetration as a priority repair
  • Check with the data sheet before painting over fire sealant
  • Agree the fire-stopping specification before services go in

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.
