Fire stopping for Niddrie Mains sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For premises in Niddrie Mains, tell us about access times, shared entrances and any building rules, so the work can be phased and areas kept in use.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  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. Anything outside the detail is reported to you rather than sealed.

Before we start on site

  • Tell staff and tenants when we will be in
  • Move anything stored against the joints
  • Point out parking and an unloading spot

Ask for a quote

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or use the quote form.

Fire stopping for commercial buildings in Niddrie Mains

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, often unnoticed. Those on your schedule are closed with the specified product. If you have builders’ foam or ordinary silicone in compartment walls and penetration schedules that need working through, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Niddrie Mains tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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.

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

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Keep general-purpose fillers away from compartment walls
  • Flag new cables with no seal around them
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Agree the fire-stopping specification before services go in

Allow the manufacturer’s stated cure time before boxing in or decorating. Not every fire-rated product can be painted, so check the product data first.

Make reporting new openings part of every permit to work in service areas. Small habits like this stop openings building up.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

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

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Surface by surface

Metal pipes

Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail and we confirm each before sealing.

Linear joints

Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in, with no gaps along the run.

What happens if it’s left?

Sealing behind the M&E trades area by area beats a sweep at the end. While the area is still open, every opening is easy to see and reach. In Niddrie Mains, as across Scotland, rain finds any gap, so a split or hardened joint lets water into the wall. Renewing them early protects the fabric.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Fire stopping around Niddrie Mains: points for this area

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, using products tested for the way they’re used. We install what’s specified, to the product’s tested detail. Six care or nursing homes sit less than 2 miles from Niddrie Mains. 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.

For a site team at a college like Edinburgh College - Milton Road Campus (1.1 miles north-east of Niddrie Mains), fire-rated sealing is best scheduled after the summer works. In a hotel such as Kings Manor Hotel (1.2 miles north-east of Niddrie Mains), new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. On a hospital site such as Royal Infirmary of Edinburgh (Little France) (1 mile south-west of Niddrie Mains), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Do you seal service penetrations in hotels around Niddrie Mains?

Yes, where the specification calls for fire-rated sealant. Each seal follows the tested detail, and rooms are done in turn.

Do you take on work at healthcare sites like Royal Infirmary of Edinburgh (Little France)?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you need to see the site first?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

How do you choose the sealant?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you work while the building is occupied?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
