Fire stopping across Hamnavoe

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

Fire stopping in Hamnavoe

No fire sealant works on its own: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and raise it with you if it falls outside. We work on pipe penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the failures we are asked to look at most are fire stopping installed outside its tested range and head-of-wall gaps with no fire seal. Most enquiries from Hamnavoe start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Travel to smaller places like Hamnavoe is planned so every penetration is sealed on one trip. Send the specification and photos of the openings, with sizes if you have them.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

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. Putting it right is normally a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. For buildings near Hamnavoe, dealing with all the failing joints at once saves return trips. Send photos and we’ll quote for everything together.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

When it isn’t the sealant

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Reviewing a building’s overall fire safety
  • Approving the work on behalf of building control
  • Openings that need collars, wraps, batts or boards rather than sealant

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.

What we seal

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

What the job involves on each surface

Plastic pipes

In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones usually call for a collar or wrap. We confirm material and size first and tell you if sealant isn’t the right product.

Cables and cable bundles

New data and power cables are the most common breach we see. We reseal around them to the specified detail.

How the quote is worked out

Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:

  • The total length or number of joints
  • Whether the work must be split into stages
  • How much existing material needs removing
  • Backing rod, priming and other preparation

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Sending details for a quote

The more we know, the firmer the quote. When you get in touch, include:

  • The product your specification calls for
  • Drawings or a marked-up plan, if available
  • Clear photos of the problem areas
  • Where the site is, with the postcode

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

From enquiry to sign-off

Before we leave any area, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Travel to smaller Scottish places like Hamnavoe is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Explain the parking and delivery arrangements
  • Send any specification or drawings in advance
  • Warn occupants and staff about the work

Quotes

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Advice

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask which product is in place before decorating
  • Include service cupboards in routine inspections
  • Agree the fire-stopping specification before services go in

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged and get them dealt with.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.

Questions about Hamnavoe

Do you design the fire stopping for buildings in Hamnavoe?

No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. We install what’s specified, to the product’s tested detail.

Can you take on a job in Hamnavoe, on the island?

Yes, Hamnavoe is within the area we cover. Our area covers all of Scotland, cities, towns and islands alike. Ferry times and the weather set the plan, so we ask for photos and a full list first.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do your applicators hold CSCS cards?

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

Are you fully insured?

Yes. Mastic Doctor is fully insured, public liability included.

Can one quote cover more than one building?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

Fire-rated sealing for Hamnavoe buildings

Island jobs, Hamnavoe among them, are planned around the ferry and the forecast. We need the specification and a count of penetrations before we sail. 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 products tested for that end use. Where fire-rated sealant is specified, that’s what we install, to the tested detail.

Buildings near Hamnavoe get the fire-rated product that’s specified, installed to its tested detail. For any site around Hamnavoe, we work to the specification and the manufacturer’s installation guidance, leaving design and sign-off with the designer.
