Fire stopping in Janetstown

Facilities managers in Janetstown often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal 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. We work on cable penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are unsealed penetrations discovered above suspended ceilings and expanding foam used as fire stopping. A single leaking joint is often how a building in Janetstown first comes to us: we look at the rest while we’re there and tell you what we find.

In smaller Scottish places like Janetstown, 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.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Questions we’re asked in Janetstown

Which Scottish guidance covers penetration seals in Janetstown?

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. We install what has been specified, to the manufacturer’s tested detail, while design and approval sit with the designer and the verifier.

Is hospital work, at somewhere like Dunbar Hospital, something you do?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Can you handle several sites?

Yes. A group of buildings can go on one quote, with one point of contact.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Do you cover Janetstown?

Yes. We cover Janetstown, and the simplest way to start is to call the office on 01277 525 020 or email drawings and photos.

Can staff carry on working while you’re here?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Service penetrations in Janetstown 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, using products tested for the way they’re used. We install what’s specified, to the product’s tested detail.

Holiday works at schools like Thurso High School often leave service openings to seal before pupils return.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • The site’s rules and procedures
  • Access and working height
  • How much there is to seal
  • Joint width, depth and condition

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

Sending details for a quote

A good diagnosis starts with the right details. Tell us:

  • Any specification or named product
  • The site address and postcode
  • When you need the work done
  • Asbestos survey details if the building is older

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call 01277 525 020 or use the quote form if you’d rather talk the job through.

Why act early in Janetstown

Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these. Around smaller places like Janetstown, halls, stores and seasonal buildings may not be checked often, so a failed joint has time to cause damage. Resealing early avoids that.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.

What you get with us

  • 12 months’ guarantee on every job
  • One contact handling all your sites
  • Fixed quotes based on photos, drawings or a visit
  • Commercial sealant work since 2005

Take a look at what affects the cost or how we’re accredited.

Site staff or a sealant specialist?

Some joints are best left to specialists: 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.

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 the job involves on each surface

Cables and cable bundles

Cable penetrations are frequently sealed with fire-rated sealant where the detail allows. The detail limits bundle size and the gaps between and around cables, so we check before sealing.

Risers and ceiling voids

Voids hide a lot of unsealed openings. We follow your schedule area by area and tell you about openings outside the list.

What we are called out for in Janetstown

Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe, and the repair is often skipped.

What tends to prompt an enquiry:

  • Seals that don’t match their tested detail
  • Builders’ foam or ordinary silicone in compartment walls
  • Fire sealant pulled out of the opening
  • Fire seals cut back for extra cables and never reinstated

Wherever services are added at a hospital such as Dunbar Hospital (1.8 miles north-east of Janetstown) the compartment line has to be made good with the specified product.

How to choose a sealant contractor

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. Jobs near Janetstown are often grouped with others in the same area. Let us know if your dates have any give.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  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.

What we need from you

  • Confirm the product named in the specification
  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work
