Fire stopping for Reay sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Fire stopping in Reay, done properly

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail, not a rule of thumb. We work on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows, and what we are called in for most is hidden openings found during inspections and builders’ foam or ordinary silicone in compartment walls. For commercial sealant work in Reay, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Refurbishments in small hotels, schools and care homes around places like Reay can leave gaps around new services. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Do you need fire stopping in Reay?

Some service penetrations were never sealed at all, often hidden above suspended ceilings or behind boxing. Inspections, refurbishments and ceiling access normally bring them to light.

Look out for the following:

  • Openings left by services added after handover
  • Non-fire-rated filler around services
  • Penetration schedules that need working through
  • Unsealed penetrations discovered above suspended ceilings

Halls and meeting rooms at places like Reay Parish Church sometimes gain new services, and any compartment wall crossed needs the specified seal.

Questions to ask before you book

  • The named product and why it was chosen
  • Their public liability cover
  • How the joint faces will be prepared and primed
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

Different surfaces, different methods

Small ducts

Ducts are only sealed with sealant where the detail allows it. The ductwork, its supports and any dampers are for the ductwork contractor.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. BS EN 1366-4 testing sets the joint widths, depths, backing and movement a seal covers and the installation has to fit inside those limits.

Compartments and services around Reay

Scottish guidance (non-domestic Technical Handbook, clause 2.1.14) asks that penetrations match at least the fire resistance period of the element they pass through, 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 buildings in and around Reay, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Reay is about 10 miles west of Thurso, in Highland. We cover commercial sites throughout Reay, whether it’s a single job or part of a planned programme. Our Highland coverage takes in 256 places, from busy centres to rural villages.

We take on service penetrations across the KW14 postcode area. If your site is on The Terrace, The Avenue and Beinn Ratha Court or close by, we can quote for service penetrations. If your building is just outside Reay, we cover Melvich (5 miles west), Portskerra (5 miles west), Forss (6 miles north-east), Westfield (6 miles east) and Janetstown (8 miles east). Where a site is remote or on an island, we plan travel and materials carefully, so include the location in your enquiry.

Around Reay

A little further out are Dounreay Castle (2.1 miles north-east). The countryside around Reay includes Caol-Loch.

Why act early in Reay

An unsealed opening affects more than fire safety: smoke, noise and draughts pass through them every day. Sealing them to the specified detail deals with the fire risk first and the building feels the difference. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Reay before they leak.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why clients in Reay choose us

  • A Constructionline member, so easy to vet
  • One phone line for London, the South East and Scotland
  • Joints cleaned back to sound surfaces
  • A fixed quote before work starts

Take a look at how commercial sealant jobs are priced and our accreditations and insurance.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Which sealant the job calls for
  • Location, for remote and island sites
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits

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 will explain how it’s made up.

What we need to price the job

To price the job accurately, we need a clear picture of the site. Send us:

  • How the joints are reached, and at what height
  • Clear photos of the problem areas
  • Asbestos survey details if the building is older
  • Where the site is, with the postcode

Photos, drawings or a schedule of the joints and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

FAQs: Reay

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

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.

Which Scottish guidance covers penetration seals in Reay?

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.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

On site: what to expect

At the end of each section, we remove the tape, clean down and inspect every joint with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Where we can, we combine work around Reay with other jobs nearby, to make the most of each trip. Tell us how flexible your dates are.

  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.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. Anything outside the detail is reported to you rather than sealed.

Getting the site ready

  • Share your working hours and any access restrictions
  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification

Request a quote

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