Why deal with it now?

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these and the building feels the difference. For buildings near Newtown St Boswells, dealing with all the failing joints at once saves return trips. Send photographs and we will quote for everything together.

There’s no price list, since every building and every scope is different. Call for a quote.

  • 12-month guarantee on workmanship
  • Joints cleaned back to sound surfaces
  • A Constructionline member, so easy to vet
  • Commercial sealant work since 2005

Fire stopping in Newtown St Boswells, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. Most enquiries involve non-fire-rated filler around services and seals that don’t match their tested detail, across joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and service gaps in risers. Most enquiries from Newtown St Boswells 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.

Travel to smaller places like Newtown St Boswells 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.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Fire-rated sealing for Newtown St Boswells buildings

There are a number of hotels within about 2 miles of Newtown St Boswells. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail. Under the Scottish non-domestic Technical Handbook, clause 2.1.14, penetrations should be fire stopped to at least the wall or floor’s fire resistance duration, with products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

On a site such as Tweed Horizons Business Centre (0.8 miles east of Newtown St Boswells), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product. In a hotel such as Dryburgh Abbey Hotel, 1 mile to the east of Newtown St Boswells, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Newtown St Boswells is about 6 miles south-east of Galashiels, in the Scottish Borders. We cover commercial sites throughout Newtown St Boswells. Our the Scottish Borders coverage takes in 91 places, large and small. Edinburgh is covered too, around 33 miles from Newtown St Boswells.

Cost factors for service penetrations

Each job is priced on its own details. The main factors are:

  • Removal of failed or old sealant
  • Access and working height
  • Distance, for remote addresses
  • Site requirements such as inductions and permits

A quote for service penetrations depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • Access details, including height
  • The type of building and who uses it
  • Specification clauses that apply
  • Photos of the joints, close up and from further back

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Your questions answered

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

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you seal around new services in a hotel near Newtown St Boswells?

Yes. We install fire-rated and intumescent sealant where it is specified. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

Can the building stay open while you work?

Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.

How many days will you need on site?

It depends on the scope, but the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we’ll set out a timescale with the quote.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

What do you charge?

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

General trades versus a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Common problems we fix in Newtown St Boswells

Openings in fire-resisting walls normally 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. Across several fit-outs, the openings add up.

These are often picked up first by site or facilities staff:

  • Fire stopping installed outside its tested range
  • Non-fire-rated filler around services
  • Fire-rated sealant that has cracked or shrunk back
  • Fire-stopping items raised at inspection or handover

At a university such as Heriot-Watt University - Scottish Borders Campus (4.7 miles north-west of Newtown St Boswells), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Before you book anyone

  • Health and safety accreditation such as CHAS
  • Their plan for phasing and protecting the area
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How the existing material will be dealt with

How to choose a sealant contractor

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Arrange inspection before areas are covered up
  • Brief every trade that openings they make must be sealed
  • Treat an open penetration as a priority repair
  • Check with the data sheet before painting over fire sealant

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way unless the designer specifies otherwise.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job compared with dozens found at once.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Tell us who will meet us and how to get in at your building near Newtown St Boswells. That goes into the plan alongside the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Unsuitable material is removed and the opening cleaned so the seal starts clean.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Tell staff and tenants when we will be in
  • Share your working hours and any access restrictions
  • Arrange parking or a loading space

Request a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email drawings and photos with what you know.
