Fire stopping near Reiss

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

How the job changes by surface

Drylining partitions

Plasterboard partitions are tested as a specific construction. The sealant detail has to be tested in that wall type, with the stated board layers first.

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

Fire stopping in Reiss, done properly

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls. Those on your schedule are closed with the specified product. We work on joints between fire-resisting walls and floors, pipe penetrations and linear gaps at wall heads, and what we are called in for most is unsealed openings around new pipes and cables and hidden openings found during inspections. A specialist sealant contractor works differently from a general builder: in Reiss, that means joint design, primers and backing rod as standard.

Hotels and care homes around smaller places like Reiss often have services added during refurbishment. A round of checks after M&E work is good practice, and any gaps found are sealed where fire-rated sealant is specified.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email a schedule or drawings and we will come back to it.

What we are called out for in Reiss

Some service penetrations were never sealed at all. They come to light during inspections, refits or when another trade lifts a tile.

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

  • Snag lists that include open service penetrations
  • Seals disturbed by maintenance and left open
  • Improvised or mixed-product fire seals
  • Openings found when ceilings come down for a refit

Hospital estates such as Caithness General Hospital (to the south-east of Reiss) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail.

What your quote should include

  • The terms of the workmanship guarantee
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • How they’ll work around occupants
  • Is the sealant right for the movement and the substrate?

Choosing a commercial sealant contractor

Keeping the joints sound

Once the work is signed off, these steps help:

  • Keep product data and details in the fire safety file
  • Include service cupboards in routine inspections
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Foam or ordinary sealant is never a fire-seal repair

Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original unless the designer specifies otherwise.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job compared with dozens found at once.

Leave it or put it right?

Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down. Exposed buildings in Scotland take a lot of weather, so it’s worth renewing joints around Reiss before they leak.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.

Why us?

  • Work carried out by CSCS-carded applicators
  • A Constructionline member, so easy to vet
  • Sealing commercial buildings since 2005
  • Old sealant cut out, never sealed over

Service penetrations in Reiss buildings

Scotland has its own building standards: the non-domestic Technical Handbook (clause 2.1.14) says service penetrations should be fire stopped to at least the fire resistance duration of the wall or floor, and products should be tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail.

Office fit-outs on sites such as Lochshell Business Park, 2 miles to the south-east of Reiss, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Reiss is about 16 miles south-east of Thurso, in Highland. Any commercial site in Reiss is covered, whether it’s a single job or part of a planned programme. We work across 256 places in Highland, large and small.

We cover the KW1 postcode districts for service penetrations. Streets here include Nordwall Park and Plover Place. Access to Reiss is via the A99 among other routes. Close to Reiss, our area also takes in Ackergillshore (2 miles east), Haster (2 miles south), Wick (3 miles south-east), Staxigoe (4 miles south-east) and Whiterow (4 miles south-east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

What’s near Reiss

Diagnose, treat, sign off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Tell us who will meet us and how to get in at your building near Reiss. We will confirm the plan with the fixed quote.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out.
  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.

Before we start on site

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Warn occupants and staff about the work

Advice

What affects the price in Reiss

Before we quote, we look at:

  • Travel to remote or island sites
  • Phasing around occupants
  • The total length or number of joints
  • Which sealant the job calls for

The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Sending details for a quote

To price the job accurately, we need to understand the site. Useful things to include:

  • The asbestos register, for older buildings
  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back

Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Common questions from Reiss clients

Is Reiss too small for you to travel to?

No. Places such as Reiss are covered as much as the big towns. We cover the whole of Scotland. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

What do Scotland’s building standards say about service penetrations in Reiss?

The non-domestic Technical Handbook, clause 2.1.14, expects a penetration to keep at least the wall or floor’s fire resistance period, with proprietary products tested for the use they’re put to. Design sits with the designer and the verifier; installation to the tested detail is our part.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

How soon can the area be used again?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

What hours do you work?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
