Fire stopping in Niddrie

A fire-rated sealant is only one part of a tested system: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow. Site teams most often ask us about service penetrations left open after M&E works and fire sealant pulled out of the opening, across cable penetrations, service gaps in risers and linear gaps at wall heads. Facilities teams, main contractors and managing agents in Niddrie tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In Scotland’s cities, university, hospital and office estates see services added year after year, 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.

Our workmanship is guaranteed for 12 months, in Niddrie as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Commercial clients in Niddrie

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Niddrie can sit alongside others in a wider programme across Edinburgh.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

What happens if it’s left?

An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. While the openings can be reached, sealing them is normally straightforward. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Getting access arranged for a building in Niddrie takes time, so it makes sense to renew every failing joint while it’s in place.

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 quote and we’ll explain how it’s made up.

Compartments and services around Niddrie

There are seven care or nursing homes within about 2 miles of Niddrie. Care settings depend on compartmentation, so service penetrations made during maintenance or refurbishment need sealing with the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. 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.

In a hotel such as Kings Manor Hotel (1.1 miles north-east of Niddrie), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. At a college such as Edinburgh College - Milton Road Campus (1 mile north-east of Niddrie), checking penetration seals after summer M&E works is good practice. At a university such as University of Edinburgh Bioquarter, 1.1 miles south-west of Niddrie, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Doing it in-house

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Questions about Niddrie

How do Scotland’s building standards affect fire-rated sealant in Niddrie?

Scotland’s non-domestic Technical Handbook covers it in clause 2.1.14: penetrations keep at least the element’s fire resistance duration, with products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.

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

Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What happens if old sealant might contain asbestos?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

How long will the new sealant last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators.

How do we ask for a quote?

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

What the job involves on each surface

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, with backing added if the detail requires it.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Diagnose, treat, sign off

Tell us your site hours and access windows and we’ll 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. Give us the access times and building rules for your premises in Niddrie, and we’ll plan the work to suit, phased where areas need to stay in use.

  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. Unsuitable material is removed and the opening cleaned.
  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.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions
  • Confirm the product named in the specification

Getting a fixed quote

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we’ll arrange a site visit.

Honesty saves time and money. New sealant won’t cure:

  • Walls or floors that aren’t fire-resisting to begin with
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Reviewing a building’s overall fire safety

If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think before you book.

Joints and surfaces we work on

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