Fire stopping in Duddingston

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Duddingston. We work on joints between fire-resisting walls and floors, cable penetrations and small duct penetrations where the tested detail allows, and the usual reasons a site gets in touch are old intumescent sealant that has split away and seals disturbed by maintenance and left open. Facilities teams, main contractors and managing agents in Duddingston tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places such as Duddingston, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Those penetrations are closed with the product the specification names, built up as tested.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Duddingston: questions and answers

Can you seal around new services in a hotel near Duddingston?

Yes, where the specification calls for fire-rated sealant. 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.

Can work at a site such as University of Edinburgh - Little France Campus fit around teaching?

Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Does the weather affect the 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.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Writing the fire-stopping specification
  • Reviewing a building’s overall fire safety
  • Large openings beyond what any sealant detail covers

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Surfaces we seal

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

Why act early in Duddingston

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme, so earlier action pays back. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, so a failed joint has time to cause damage. Resealing early avoids that.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

What you get with us

  • A fixed quote before work starts
  • 12 months’ guarantee on every job
  • Over 20 years of commercial sealing
  • A Constructionline member, so easy to vet

From enquiry to sign-off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building near Duddingston, directions, keys and a contact on the day are worth sorting early. We will confirm the plan with the fixed quote.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

Getting the site ready

  • Let building users know which areas are affected
  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand

Service penetrations in Duddingston buildings

10 care or nursing homes sit less than 2 miles from Duddingston. 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. 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, with proprietary products, intumescent ones included, tested for their end use. Our part is installing the specified fire-rated sealant to its tested detail.

Tenant changes at centres like Craigmillar Shopping Centre (to the south-east of Duddingston) often mean new services through walls between units. Large healthcare estates like Royal Infirmary of Edinburgh (Little France) (to the south of Duddingston) change their services often, so penetration seals are worth checking after M&E work.

Duddingston is about 1 mile south-west of South Portobello, in Edinburgh. Looking for fire stopping in Duddingston? We can help. Our Edinburgh coverage takes in 174 places, from busy centres to rural villages.

What we’re called out for in Duddingston

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and a product not tested for that movement may crack. Linear joint details set a width range and movement capability, and the seal has to sit within them.

Look out for the following:

  • Non-fire-rated filler around services
  • Snag lists that include open service penetrations
  • Seals disturbed by maintenance and left open
  • Unsealed penetrations discovered above suspended ceilings

At a college such as Edinburgh College - Milton Road Campus, which lies east of Duddingston, checking penetration seals after summer M&E works is good practice.

Questions to ask before you book

  • Are they CHAS accredited or on Constructionline?
  • How they handle RAMS and site documents
  • Whether their applicators hold CSCS cards
  • Can the work be phased to keep areas open?
