Fire stopping for Shiplake sites

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

General trades versus a specialist

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Fire stopping in Shiplake, done properly

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance in Shiplake and nearby. The enquiries we see most involve snag lists that include open service penetrations and fire stopping installed outside its tested range, across cable penetrations, pipe penetrations and linear gaps at wall heads. A single leaking joint is often how a building in Shiplake first comes to us: we look at the rest while we are there and tell you what we find.

A job near Shiplake is normally planned around one visit, with the specification and photos sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Different surfaces, different methods

Drylining partitions

Drylined fire walls are tested in a particular build-up. The sealant detail has to be tested in that wall type, with the stated board layers.

Metal pipes

Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail.

Shiplake: questions and answers

Does your area include sites such as Castle End Business Park, near Shiplake?

Yes. Our area takes in Shiplake and its surroundings, with estates and business parks such as Castle End Business Park included. A few photographs and the unit address let us price the work.

Do you seal service penetrations in hotels around Shiplake?

Yes, where the specification calls for fire-rated sealant. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photos and measurements, and bigger or more complex jobs typically get a visit.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Smaller jobs around Shiplake can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Tell us your opening times and when work is allowed
  • Arrange parking or a loading space
  • Have the specification and drawings to hand

Fire-rated sealing for Shiplake buildings

Central London is about 35 miles from Shiplake. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

Wherever services are added at a hospital such as Townlands Memorial Hospital, 2.8 miles to the north of Shiplake, the compartment line has to be made good with the specified product. Tenant changes at parks like Castle End Business Park (2.5 miles east of Shiplake) bring new data and services, and openings through fire-resisting walls need the specified seal. Older community buildings such as Church of St Peter and St Paul that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Shiplake is about 3 miles north of Woodley, in Oxfordshire. Commercial clients in Shiplake use us for work on service penetrations. We work across 423 places in Oxfordshire, large and small.

We cover the RG9 postcode districts. Sites close to Shiplake are covered too, including Charvil (2 miles south), Twyford (2 miles south-east), Ruscombe (2 miles south-east), Hare Hatch (2 miles east) and The Holt (3 miles east). Bigger towns within reach include Benson (12 miles north-west), Chinnor (14 miles north), Wallingford (12 miles north-west), Sonning Common (4 miles west), Oakley (14 miles north) and Watlington (11 miles north-west).

Building owners, agents and FMs in Shiplake

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Shiplake can sit alongside others in a wider programme.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

What sealant work can’t fix

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

  • Openings that need collars, wraps, batts or boards rather than sealant
  • Signing off or certifying a building’s fire stopping
  • Writing the fire-stopping specification

Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we’ll tell you honestly before you book.

What we seal

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

Maintenance after handover

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

  • Report damaged or disturbed seals as soon as they’re spotted
  • Check with the data sheet before painting over fire sealant
  • Record which product was used where
  • Agree the fire-stopping specification before services go in

During planned inspections, look at seals in risers, cupboards and voids. Watch for cracked sealant, new services with no seal and openings that have grown, and report them promptly.

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 the work runs in step with the M&E.
