Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Woodside can form part of a wider programme across Dundee.

Building owners and managing agents use us on everything from one building to a spread of sites around Woodside. One quote can cover more than one site, so there’s one set of paperwork to deal with.

About our fire stopping in Woodside

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind. Those on your schedule are closed with the specified product. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and seals disturbed by maintenance and left open, on joints between fire-resisting walls and floors, small duct penetrations where the tested detail allows and service gaps in risers. Looking for mastic applicators who cover Woodside? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Large city estates in Scotland, from universities to hospitals and offices, are re-serviced constantly, and new cabling and pipework through compartment walls is a common reason fire stopping gets breached. New openings are closed with the specified fire-rated product, following its test evidence.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why deal with it now?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is typically a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Failed sealant in a shared building in Woodside can affect more than one owner, which makes early repair simpler for everyone. Acting early avoids disputes and bigger repairs.

The work involved drives the cost: 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.

Why us?

  • Fully insured
  • A Constructionline member, so easy to vet
  • One phone line for London, the South East and Scotland
  • Sealing commercial buildings since 2005

Different surfaces, different methods

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. Each gap is measured where it is widest against the detail’s limits, and any that don’t are flagged.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. We use the product and backing the detail names for that movement, along the full length of the run.

When something else is needed

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Walls or floors that aren’t fire-resisting to begin with
  • Reviewing a building’s overall fire safety

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Joints and surfaces we work on

  • Cable penetrations
  • Joints between fire-resisting walls and floors
  • Service gaps in risers
  • Small duct penetrations where the tested detail allows
  • Pipe penetrations
  • Linear gaps at wall heads

What we are called out for in Woodside

Openings in fire-resisting walls typically appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

Typical triggers for a call:

  • Openings left by services added after handover
  • Damaged fire seals in risers and voids
  • Fire-stopping items raised at inspection or handover
  • Improvised or mixed-product fire seals

Hotels like Hotel Indigo Dundee, 1 mile to the south of Woodside, are refurbished in phases, and each phase can open up compartment walls.

Questions to ask before you appoint anyone

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building, and we clear our waste as we work. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Tell us the rules and we will work to them.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Unsuitable material is removed and the opening cleaned.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Send any specification or drawings in advance
  • Share your working hours and any access restrictions
  • Let us know about inductions and permits

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Fire stopping around Woodside: how the place shapes the job

Woodside has a good number of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. The 2 miles around Woodside include 10 care or nursing homes. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. We install fire-rated sealant to the tested detail where it is specified.

Colleges such as Dundee and Angus College - Kingsway Campus (to the north-west of Woodside) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. At a retail site such as Kingsway West Retail Park, which lies west of Woodside, walls between units may be fire-resisting, so services added in a refit need the specified seal.

Woodside is about 1 mile north-east of Dundee, in Dundee. Looking for fire stopping in Woodside? We can help, as we do across Dundee. Woodside is one of 28 places we cover in Dundee.

Your questions answered

Will you plan work around the academic year at somewhere like Abertay University?

Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Do you work on fire-rated sealing in hotels in Woodside?

Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Do you offer coloured sealant?

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.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

What about RAMS and site documents?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

How do I request a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
