Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Maintenance after handover

Regular inspection catches problems early. In particular:

  • Record which product was used where
  • Leave fire sealant to cure fully before covering it
  • Arrange inspection before areas are covered up
  • Put resealing into every M&E and fit-out package

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Fire stopping in Newhaven

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail rather than guesswork. If you have snag lists that include open service penetrations and unsealed joints where partitions meet the slab, we can put it right. Most enquiries from Newhaven start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Older stone and tenement buildings in Scotland’s cities have normally been re-serviced many times. Wall type and service type decide the product, so both are checked before sealing, and design questions go to the designer or verifier.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Questions we’re asked in Newhaven

Will you work in a care home in Newhaven without moving residents out?

Yes. We agree rooms and times with the manager and work a few areas at a time. We follow the home’s own procedures throughout.

Will you plan work around the academic year at somewhere like University of Edinburgh - Holyrood Campus?

Yes. Education sites typically 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.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

What do you charge?

We don’t publish prices, because every site is different. With photos or drawings, we can give you a fixed quote.

What we are called out for in Newhaven

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is when untested combinations creep in, which then have to be put right.

These are often picked up first by site or facilities staff:

  • Head-of-wall gaps with no fire seal
  • Damaged fire seals in risers and voids
  • Unsealed penetrations discovered above suspended ceilings
  • Openings left by services added after handover

For a site team at a college like Royal College of General Practitioners Edinburgh (1.7 miles south of Newhaven), fire-rated sealing is best scheduled after the summer works.

Our contractor checklist

Fire stopping in Newhaven: the local picture

The 2 miles around Newhaven include six care or nursing homes. In a care home, any new pipe or cable through a fire-resisting wall should be sealed to the specified detail. 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.

In a retail centre such as Newkirkgate Shopping Centre, which lies south-east of Newhaven, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. For a hospital such as Western General Hospital (Edinburgh), which lies south-west of Newhaven, penetration sealing is usually phased ward by ward, with infection-control rules agreed first.

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Pass on the site’s contractor rules when you get in touch.

  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.

Preparing the site

  • Share your working hours and any access restrictions
  • Let building users know which areas are affected
  • Agree which areas must stay open

What the job involves on each surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point so we know it sits within the tested range, and any that don’t are flagged.

Plastic pipes

Plastic pipes soften and collapse in a fire. Small sizes are sometimes covered by an intumescent sealant detail. We check the pipe material and diameter against the detail before we start.

What affects the price in Newhaven

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • How accessible the joints are
  • Location, for remote and island sites

Pricing service penetrations depends on quantities, condition and access, plus any specification you are working to. Call for a quote.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • Any dates the work must fit around
  • Specification clauses that apply

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email us.

Why it’s worth doing now in Newhaven

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. While the area is still open, every opening is easy to see and reach. In a tenement or shared city building, water from a failed joint can reach other owners’ property. Acting early avoids disputes and bigger repairs.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
