Fire stopping for Ness sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs near Ness are often grouped with others in the same area. Let us know if your dates have any give.

  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 so the seal starts clean.
  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.

What we need from you

  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs
  • Make sure the joints can be reached

Getting a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

About our fire stopping in Ness

Opened ceilings and riser doors often reveal service openings nobody sealed. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. Most enquiries involve seals disturbed by maintenance and left open and seals that don’t match their tested detail, across pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads. Whoever orders the work in Ness, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places such as Ness, compartment walls and floors tend to be in schools, hotels, care homes and community buildings. Where services pass through, specified fire-rated sealant is installed following the manufacturer’s guidance for that wall or floor.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Fire-rated sealing for Ness buildings

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, and products should be tested for their end use. We install what’s specified, to the product’s tested detail. For an island location such as Ness, work is planned around ferry crossings and the weather. Photos of each opening and the specification mean the right products make the trip.

For buildings in and around Ness, fire-rated sealant is installed where it is specified, to the manufacturer’s tested detail.

Ness is about 18 miles north of Stornoway, in Na h-Eileanan Siar. Commercial clients in Ness use us for work on service penetrations. 87 places across Na h-Eileanan Siar fall within our area, Ness among them.

We take on service penetrations across the HS2 postcode area. Nearby places we also cover include Nis (1 mile north), Cross (1 mile west), Sgiogarstaigh (1 mile east), Lionel (1 mile north) and North Dell (2 miles west) for service penetrations. Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Agree the fire-stopping specification before services go in
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Report damaged or disturbed seals as soon as they’re spotted
  • Foam or ordinary sealant is never a fire-seal repair

New services after handover are a common way fire stopping gets breached. Building it into each contractor’s sign-off keeps the walls intact.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and the work runs in step with the M&E.

Why it’s worth doing now in Ness

Inspections and handover checks often pick up fire stopping. Finding unsealed or improvised openings late can hold up a programme which is why earlier is better. Buildings that aren’t in daily use, such as halls and seasonal premises, may let water in unnoticed, giving water time to get in. Early resealing prevents it.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Read what affects the cost or how we’re accredited.

Cost factors for service penetrations

These are the things that shape the price:

  • The site’s rules and procedures
  • Working within restricted access windows
  • Removal of failed or old sealant
  • Any access equipment needed

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • The postcode of the building
  • The asbestos register, for older buildings
  • Any dates the work must fit around
  • A wide shot and a close-up of the area

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Common problems we fix in Ness

Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. They come to light during inspections, refits or when another trade lifts a tile.

Any of the following is a good reason to get the joints checked over:

  • Builders’ foam or ordinary silicone in compartment walls
  • Snag lists that include open service penetrations
  • Hidden openings found during inspections
  • Open linear gaps along the top of fire-resisting walls

Wherever the building is near Ness, design and sign-off of fire stopping sit with the designer, fire engineer or building control; we install what has been specified.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • How they’ll work around occupants
  • How the existing material will be dealt with
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Common questions from Ness clients

Is Ness inside the area you cover, given it’s on an island?

Yes. Islands are part of our area, Ness included. Ferry times and the weather set the plan, so we ask for photographs and a full list first.

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

Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. The detail is set by the designer and goes through the warrant process; we install the specified product to its tested detail.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Is it fine to apply new sealant on top of old?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

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.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
