About our fire stopping in Danderhall

It helps to set out our role at the start. Deciding the specification sits with the designer, the fire engineer and building control. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on sites in Danderhall. We work on linear gaps at wall heads, joints between fire-resisting walls and floors and cable penetrations, and the usual reasons a site gets in touch are seals that don’t match their tested detail and fire-stopping items raised at inspection or handover. A specialist sealant contractor works differently from a general builder: in Danderhall, that means joint design, primers and backing rod as standard.

Refurbishments in small hotels, schools and care homes around places like Danderhall can leave gaps around new services. We fit the specified fire-rated sealant as its published detail shows and raise it if another product is needed.

A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or use the quote form and we will come back to it.

How a job runs

Diagnose, treat, sign off: every visit follows that pattern. 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. For work around Danderhall, we aim for one trip, which is why we ask for photographs and a full list first. External joints need a dry spell as well.

  1. The specification and schedule come first, so we know which details apply.
  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. Foam, ordinary sealant and debris come out.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Before we start on site

  • Flag any permit to work we’ll need
  • Share the asbestos register for older buildings
  • Move anything stored against the joints

Advice

Leave it or put it right?

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 usually a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. Exposed buildings in Scotland take a lot of weather, and for a smaller place like Danderhall, a repair visit takes planning, so it’s better to act early.

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

Surface by surface

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail, though larger ones typically call for a collar or wrap. We check the pipe material and diameter against the detail before we start.

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.

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Danderhall can form part of a wider programme.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Penetration seals near Danderhall

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, using products tested for the way they’re used. We install what’s specified, to the product’s tested detail. The 2 miles around Danderhall include three care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.

Theatres, wards and plant rooms at sites like Shawfair Park Hospital (to the south-east of Danderhall) all have compartment walls crossed by services. For a building at a site such as Scotway Business Centre (0.7 miles east of Danderhall), a check of penetration seals after each fit-out is good practice. Campus buildings at universities such as University of Edinburgh Bioquarter (to the north-west of Danderhall) see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Danderhall is about 2 miles north-west of Dalkeith, in Midlothian. We cover commercial sites throughout Danderhall, for single jobs and planned programmes alike. Danderhall is one of 34 places we cover in Midlothian.

Danderhall: questions and answers

Would you work within a site like Shawfair Park Hospital?

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.

Is Scotway Business Centre, near Danderhall, within your area?

Yes. Estates, retail parks and business parks around Danderhall, Scotway Business Centre among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Is fire stopping in Scotland covered by different guidance?

Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, using products tested for their end use.

How do we ask for a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

Is your workmanship covered by a guarantee?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, though not damage or work by other trades.

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Construction that lacks the fire resistance the seal relies on
  • Reviewing a building’s overall fire safety
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

What we seal

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