Fire stopping in Newtown

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. 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. We work on linear gaps at wall heads, service gaps in risers and pipe penetrations, and the usual reasons a site gets in touch are builders’ foam or ordinary silicone in compartment walls and old intumescent sealant that has split away. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Newtown is the same: the right product in a properly prepared joint.

Refurbishments in small hotels, schools and care homes around places like Newtown can leave gaps around new services. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

Every job we finish is backed by a 12-month workmanship guarantee, in Newtown as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Do you need fire stopping in Newtown?

Some seals fail because the wrong product went in: expanding foam or a general-purpose sealant pushed into a gap to tidy it. It may look closed, but it has no tested fire performance in that position and has to be removed.

What tends to prompt an enquiry:

  • Builders’ foam or ordinary silicone in compartment walls
  • Penetration schedules that need working through
  • Damaged fire seals in risers and voids
  • Open linear gaps along the top of fire-resisting walls

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

Questions to ask before you book

  • What the guarantee covers, and for how long
  • How the existing material will be dealt with
  • How joint depth will be controlled
  • Whether their applicators hold CSCS cards

Our contractor checklist

Building owners, agents and FMs in Newtown

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Aftercare for building managers

A few simple habits keep the new joints working:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open instead of being left for someone else.

Questions we’re asked in Newtown

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

No, that sits with the designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

Is Newtown too far out for you?

No. Places such as Newtown are covered as much as the big towns. Our area covers all of Scotland, cities, towns and islands alike. Where we can, we group nearby jobs to make the most of each trip.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

How long does a typical visit take?

It depends on the scope, though a typical visit usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Do you have public liability insurance?

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

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Fire-rated sealing for Newtown buildings

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. Our part is installing the specified fire-rated sealant to its tested detail.

For any site around Newtown, we work to the specification and the manufacturer’s installation guidance, leaving design and sign-off with the designer.

Newtown is about 31 miles south-west of Inverness, in Highland. Newtown sits inside our coverage and the rest of Highland, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 256 places in Highland, from busy centres to rural villages. Our Dundee page has more on work in that area (79 miles or so).

Commercial sites across PH35 are covered. Close to Newtown, our area also takes in Aberchalder (1 mile south-west), Fort Augustus (3 miles north-east), Glen Moriston (6 miles north-west), Laggan (6 miles south-west) and Invermoriston (9 miles north-east). Remote and island addresses take more planning, from travel and ferries to the weather, so give the site location in your enquiry.

How the job changes by surface

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. An oversized hole may be outside the sealant’s range.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area, and note anything we find that isn’t on it.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs near Newtown are often grouped with others in the same area, to make the most of each trip. Tell us how flexible your dates are.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  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. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Confirm the product named in the specification
  • Tell us which areas need to stay in use
