Fire stopping in Hermitage

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

How we handle fire stopping in Hermitage

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance on buildings around Hermitage. We work on joints between fire-resisting walls and floors, pipe penetrations and small duct penetrations where the tested detail allows, and what we’re called in for most is unsealed openings around new pipes and cables and damaged fire seals in risers and voids. Most enquiries from Hermitage 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.

Rural conversions around Hermitage can put new fire-resisting partitions inside older structures. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What affects the price in Hermitage

Before we quote, we look at:

  • Location, for remote and island sites
  • Whether the work must be split into stages
  • Access and working height
  • Quantities, in metres or numbers

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • The type of building and who uses it
  • Whether an asbestos survey exists
  • Access details, including height
  • Where the site is, with the postcode

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or send details through our quote form.

Common questions from Hermitage clients

Can you take on a job at a hospital such as West Berkshire Community Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Hermitage off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.

How much does the work cost?

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

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Is fire stopping in Scotland covered by different guidance?

Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Either way, we install the specified sealant to its tested detail.

Will you write the fire-stopping specification?

No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is installing what they specify, to the product’s tested detail.

Is the BS 476 change in 2029 relevant to fire stopping?

It mainly affects England, where Approved Document B is dropping its BS 476 references from 2 September 2029. Classification to BS EN 13501-2 becomes the expected evidence, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance, including clause 2.1.14 on service penetrations.

When something else is needed

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Large openings beyond what any sealant detail covers
  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly.

Where we work in Hermitage

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

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Don’t let anyone top up a fire seal with the wrong product
  • Ask the designer to confirm details early on refits
  • Brief every trade that openings they make must be sealed
  • Get seals inspected before ceilings and boxing close

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open, not months later.

Commercial clients in Hermitage

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

How a job runs

On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually takes anything from one day to a planned run of visits, depending on the number of seals and the access. For work around Hermitage, we aim to finish in one visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  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. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Arrange parking or a loading space
  • Move anything stored against the joints
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or email a schedule or drawings.

Signs you need fire stopping in Hermitage

Most open service penetrations are left by later work. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

Clients normally get in touch after noticing one or more of the following:

  • Old intumescent sealant that has split away
  • Damaged fire seals in risers and voids
  • Snag lists that include open service penetrations
  • Fire stopping installed outside its tested range

In a school such as Hermitage Primary School, fire-rated sealant goes in around service penetrations where it is specified.

Questions to ask before you book

  • How they handle RAMS and site documents
  • Do they follow the manufacturer’s priming guidance?
  • Can the work be phased to keep areas open?
  • Will failed sealant be removed rather than covered?

Questions to ask before you appoint anyone

Fire-rated sealing for Hermitage buildings

Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. Central London is about 51 miles from Hermitage. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Wherever services are added at a hospital such as West Berkshire Community Hospital (to the south of Hermitage) the compartment line has to be made good with the specified product. For a building such as Holy Trinity, new heating or data runs are the usual reason penetrations need sealing.

Hermitage is about 4 miles north of Thatcham, in West Berkshire. Anywhere in RG18, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Hermitage is one of 140 places we cover in West Berkshire for service penetrations. We also cover Reading, around 13 miles from Hermitage.

Commercial sites across RG18 are covered for service penetrations. If your site is on Newbury Road, Lipscomb Close and Marlston Road or close by, we can quote for service penetrations. Just outside Hermitage, we also work in Longlane (1 mile south-west), Little Hungerford (1 mile north-east), Oare (1 mile north), Wellhouse (1 mile east) and Curridge (1 mile south-west). Further afield, our area takes in Newbury (4 miles south-west), Thatcham (4 miles south), Burghfield Common (10 miles east), Speenhamland (4 miles south-west), Hungerford (11 miles west) and Fords Farm (11 miles east).

Around Hermitage

Locally, jobs take us to sites close to The White Horse pub and the streets around them. For rail, the closest station is Newbury Racecourse station, roughly 4 miles south of the centre. Well-known places in the area include Hampstead Norris Castle (2.4 miles north-east) and West Berkshire Community Hospital (3.3 miles south). Not far away are Snelsmore Common.
