Fire stopping for Fyfield sites

About our fire stopping in Fyfield

It helps to set out our role at the start. The designer, fire engineer or building control decides which fire stopping is required. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Fyfield. We work on service gaps in risers, cable penetrations and small duct penetrations where the tested detail allows, and what we are called in for most is fire sealant pulled out of the opening and expanding foam used as fire stopping. A specialist sealant contractor works differently from a general builder: on jobs in Fyfield, preparation and product choice get the time they need.

Smaller places such as Fyfield still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Service penetrations in Fyfield buildings

Central London is about 57 miles from Fyfield. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail.

Holiday works at schools like Abingdon Preparatory School often leave service openings to seal before pupils return. Wherever services are added at a hospital such as Abingdon Community Hospital, 4 miles to the east of Fyfield, the compartment line has to be made good with the specified product.

Fyfield is about 5 miles west of Abingdon-on-Thames, in Oxfordshire. Businesses, contractors and managing agents in Fyfield use us for work on service penetrations, as part of our coverage of Oxfordshire. We work across 423 places in Oxfordshire, from busy centres to rural villages. For work in that direction, see our Oxford page.

Postcode districts covered here: OX13 for service penetrations. Buildings on Main Road, Netherton Lane and St John's Close are within our area. If your building is just outside Fyfield, we cover Netherton (1 mile north-west), Tubney (1 mile east), Frilford Heath (2 miles east), Frilford (2 miles south-east) and Marcham (2 miles south-east). A short drive away, we cover Oxford (8 miles north-east), Didcot (8 miles south-east), Abingdon-on-Thames (5 miles east), Witney (8 miles north-west), Carterton (10 miles north-west) and Wantage (7 miles south).

Local landmarks in Fyfield

We work on buildings around The White Hart Inn. A little further out are Hinton Waldrist Castle (2.9 miles west) and Abingdon Community Hospital (4 miles east). For a walk, there’s Cumnor Hill and Hitchcopse Pit.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Check with the data sheet before painting over fire sealant
  • Brief every trade that openings they make must be sealed
  • File the specified details where the next contractor can find them
  • Settle who seals which penetrations at the start of a project

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Some fire-rated sealants accept paint and some don’t, and the data sheet says which.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.

Our process

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. If others near Fyfield need work, visits can be combined. A fixed quote is given before anything starts.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings
  • Confirm the product named in the specification

Advice

Cost factors for service penetrations

A fixed quote reflects the actual work. It takes account of:

  • Removal of failed or old sealant
  • How accessible the joints are
  • Joint width, depth and condition
  • Whether the work must be split into stages

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • How the joints are reached, and at what height
  • Asbestos survey details if the building is older
  • Approximate linear metres or a joint schedule
  • Any dates the work must fit around

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Signs you need fire stopping in Fyfield

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 and later need putting right.

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

  • Fire-stopping items raised at inspection or handover
  • Builders’ foam or ordinary silicone in compartment walls
  • Unsealed joints where partitions meet the slab
  • Seals that don’t match their tested detail

In a building such as Church of St Nicholas, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Our contractor checklist

Leave it or put it right?

Open service penetrations matter on ordinary days, not just in a fire: smoke, noise and draughts pass through them every day. The specified fire seal closes the gap for all of these. Older rural buildings around Fyfield move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

What you get with us

  • Constructionline member
  • One phone line for London, the South East and Scotland
  • CSCS-carded applicators
  • Failed material removed, not covered up

Questions we’re asked in Fyfield

Will you plan work around the academic year at somewhere like University of Oxford?

Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a smaller place like Fyfield outside your area?

No. Places such as Fyfield are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

What will the job cost?

Each job is quoted on its own details. To get one, call the office on 01277 525 020 or email the details over with a description of the work.

Is sealant suitable for all service openings?

No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards.

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.

Is fire stopping in Scotland covered by different guidance?

Building standards in Scotland are separate from England’s, and England uses Approved Document B. Wherever the site is, our work follows the specification and the tested detail.
