Fire stopping across Halfway

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

What happens if it’s left?

It is cheaper to seal service penetrations as each services package finishes than to come back for them later. Openings are visible, access is open and nothing has to be taken down, and the right detail can be checked at the time. Converted and older buildings near places like Halfway tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Why appoint us

  • CHAS accredited contractor
  • Clear, fixed quotes
  • CSCS-carded applicators

Fire stopping in Halfway, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it. Where there isn’t one, the designer or fire engineer needs to set one first. We work on joints between fire-resisting walls and floors, linear gaps at wall heads and small duct penetrations where the tested detail allows, and what we’re called in for most is service penetrations left open after M&E works and builders’ foam or ordinary silicone in compartment walls. A single leaking joint is often how a building in Halfway first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places like Halfway, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

Common problems we fix in Halfway

Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Movement in the frame or slab can open the joint, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.

Common reasons buildings call us in:

  • Hidden openings found during inspections
  • Fire-stopping items raised at inspection or handover
  • Improvised or mixed-product fire seals
  • Service penetrations left open after M&E works

Large healthcare estates like West Berkshire Community Hospital (to the east of Halfway) change their services often, so penetration seals are worth checking after M&E work.

Questions to ask before you appoint anyone

Quoting for work in Halfway

Before we quote, we look at:

  • Whether old sealant has to be cut out first
  • The product specified
  • Distance, for remote addresses
  • The size and state of each joint

Pricing service penetrations depends on how many there are, their condition and the access. Ask us for a fixed quote.

What we need to price the job

Good information means a firmer quote. Helpful details to send:

  • Anything awkward about access or site hours
  • A wide shot and a close-up of the area
  • Specification clauses that apply
  • When you need the work done

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to call the office on 01277 525 020 or use the quote form.

When something else is needed

Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:

  • Large openings beyond what any sealant detail covers
  • Deciding what a wall or floor needs, which belongs to the designer
  • Fire risk assessments, a job for a competent assessor

If in doubt, give us a call on 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

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

Where services cross fire walls in Halfway

Halfway is about 57 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Several hotels sit less than 2 miles from Halfway. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close.

Halls and meeting rooms at places like Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. In a hotel such as Elcot Park Hotel, 0.9 miles to the north-west of Halfway, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.

Halfway: questions and answers

Do you take on work at healthcare sites like West Berkshire Community Hospital?

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

Is Halfway off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Can you quote from photos?

That depends on the size and complexity of the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

Do you certify or sign off fire stopping?

No. We don’t certify or sign off fire stopping, and we hold no third-party fire-stopping installer certificate. Our part is fitting the specified product to its tested detail.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

What do you charge?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we will price it properly.

How the job changes by surface

Drylining partitions

Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do.

Metal pipes

Heat travels along metal pipework, and the tested detail may ask for insulation beyond the wall. We follow whatever the detail requires and flag anything we can’t match.

On site: what to expect

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. Smaller jobs around Halfway can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.

  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. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Share your working hours and any access restrictions
  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send photos by email.
