Fire stopping in Claverhouse, 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 the failures we’re asked to look at most are old intumescent sealant that has split away and seals disturbed by maintenance and left open. Most enquiries from Claverhouse 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.

Tenement blocks and converted stone buildings in Scottish cities often hide old service routes through walls and floors. Before sealing, we confirm the wall or floor and the services passing through, so the product matches the detail, and design questions go to the designer or verifier.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Compartments and services around Claverhouse

There are five care or nursing homes within about 2 miles of Claverhouse. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified 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, and products should be tested for their end use. We install fire-rated sealant to that tested detail where it is specified.

Large healthcare estates like Kings Cross Hospital, 1.4 miles to the south-west of Claverhouse, change their services often, so penetration seals are worth checking after M&E work. At a university such as Abertay University (2.1 miles south of Claverhouse), labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Claverhouse is about 1 mile north of Dundee, in Dundee. Across the DD3 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Claverhouse is one of 28 places in Dundee on our list.

Anyone looking for fire stopping in DD3 and DD4 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Newton Road, Emmock Road and Emmock Lane or close by, we can quote for service penetrations. Nearby places we also cover include Mill of Mains (1 mile south-east), Woodside (1 mile south), Downfield (1 mile west), Balgowan (1 mile west) and Pitkerro (1 mile south-east) for service penetrations. Further afield, our area takes in Broughty Ferry (4 miles east), Blackness (3 miles south-west), Barnhill (4 miles east), Logie (3 miles south-west), Balgay (3 miles south-west) and West End (3 miles south-west).

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so the building keeps working while we do.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Claverhouse can sit alongside others in a wider programme.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Put resealing into every M&E and fit-out package
  • Foam or ordinary sealant is never a fire-seal repair
  • File the specified details where the next contractor can find them
  • Agree the fire-stopping specification before services go in

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; found late, it can be one of many.

Signs you need fire stopping in Claverhouse

Head-of-wall joints and wall-to-wall junctions are frequent weak points. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

Look out for the following:

  • Fire-stopping items raised at inspection or handover
  • Fire seals cut back for extra cables and never reinstated
  • Openings found when ceilings come down for a refit
  • Open linear gaps along the top of fire-resisting walls

Workshops and IT rooms at colleges like Dundee and Angus College - Kingsway Campus (to the south-west of Claverhouse) are re-serviced often, leaving penetrations to seal.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • What site paperwork they can supply
  • Their plan for phasing and protecting the area
  • How the joint faces will be prepared and primed

Our contractor checklist

Cost factors for service penetrations

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Any access equipment needed
  • Specialist products, such as fire-rated or hygienic sealants
  • The site’s rules and procedures
  • Joint width, depth and condition

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

What to include in your enquiry

A few photos plus some basic facts will normally do. Please tell us:

  • The site address and postcode
  • When you need the work done
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or email us.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Your questions answered

Could you schedule work at a campus like Abertay University for the vacation?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Which Scottish guidance covers penetration seals in Claverhouse?

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.

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

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 will set out a timescale with the quote.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.

On site: what to expect

Inspect, seal, sign off: that’s the shape of every visit. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. City jobs in Claverhouse typically need parking and loading planned. Tenement closes, shared stairs and factor approvals may also be involved.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Getting the site ready

  • Share your working hours and any access restrictions
  • Arrange parking or a loading space
  • Make sure the joints can be reached
