Fire stopping in Wash Common

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

Fire stopping for commercial buildings in Wash Common

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on pipe penetrations, small duct penetrations where the tested detail allows and cable penetrations, and the usual reasons a site gets in touch are seals disturbed by maintenance and left open and non-fire-rated filler around services. A single leaking joint is often how a building in Wash Common first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around Wash Common, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered

Will you plan work around the academic year at somewhere like Newbury College?

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 Newbury Retail Park, near Wash Common, within your area?

Yes. Estates, retail parks and business parks around Wash Common, Newbury Retail Park among them, are all within reach. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Is BS 476 being phased out?

For buildings in England, Approved Document B removes BS 476 references from 2 September 2029. Products are then judged on BS EN 13501-2 classifications, though transitional rules apply. In Scotland, the Technical Handbook sets its own guidance.

Do you work in Scotland as well as England?

Scotland sets its own building regulations, with Technical Handbooks, while England relies on Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. For buildings in places like Wash Common, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

What you get with us

  • Public liability insurance in place
  • CSCS-carded applicators

Aftercare for building managers

Regular inspection catches problems early. In particular:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Leave fire sealant to cure fully before covering it
  • Keep product data and details in the fire safety file
  • Arrange inspection before areas are covered up

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Common problems we fix in Wash Common

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.

Any of the following is a good reason to get the joints checked over:

  • Expanding foam used as fire stopping
  • Fire-stopping items raised at inspection or handover
  • Openings found when ceilings come down for a refit
  • Old intumescent sealant that has split away

Colleges such as Newbury College, 1 mile north-east of Wash Common, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Questions to ask before you book

  • How long is the guarantee, and what does it include?
  • Which product they’ll use, and why it suits the joint
  • Whether their applicators hold CSCS cards
  • Their pre-qualification and accreditations

Our contractor checklist

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Fire stopping around Wash Common: points for this area

In England, Approved Document B covers fire stopping of openings and penetrations. 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. A number of hotels sit less than 2 miles from Wash Common. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

On a hospital site such as West Berkshire Community Hospital (3.1 miles north-east of Wash Common), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Shop fits on retail sites such as Newbury Retail Park, 1.3 miles to the north-east of Wash Common, can bring new services through fire-resisting walls between units, to be sealed with the specified product.

Wash Common is about 2 miles south-west of Newbury, in West Berkshire. We cover Wash Common and the rest of West Berkshire, with the same fixed quotes and 12-month guarantee as everywhere else. 140 places across West Berkshire fall within our area, including Wash Common.

Site staff or a sealant specialist?

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. If neighbouring businesses or buildings around Wash Common need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  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.

What we need from you

  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings
  • Make sure the joints can be reached
