Signs you need fire stopping in Newbury

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access usually bring them to light.

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

  • Fire-stopping items raised at inspection or handover
  • Fire-rated sealant that has cracked or shrunk back
  • Seals disturbed by maintenance and left open
  • Unsealed openings around new pipes and cables

On a hospital site such as West Berkshire Community Hospital, 1.5 miles to the east of Newbury, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits.

Questions to ask before you book

  • Their approach to joint depth and backing
  • How long is the guarantee, and what does it include?
  • How they handle RAMS and site documents
  • What level of public liability insurance do they hold?

Fire stopping for commercial buildings in Newbury

Penetration seals are fire tested to BS EN 1366-3 and linear joint seals to BS EN 1366-4. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. We work on cable penetrations, linear gaps at wall heads and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are non-fire-rated filler around services and unsealed openings around new pipes and cables. Looking for mastic applicators who cover Newbury? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Many town-centre buildings in places like Newbury have had layer upon layer of new services, and each change can leave unsealed holes in walls and floors. Intumescent or fire-rated sealant is used wherever the specification asks for it, built up exactly as tested.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and work section by section so the rest of the building stays in use. For a town like Newbury, we try to group jobs for the same client into one visit. Tell us when the building is open and we’ll plan to suit.

  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. 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. We walk the completed areas with you and confirm the records agreed at quote stage.

What we need from you

  • Warn occupants and staff about the work
  • Point out parking and an unloading spot
  • Agree which areas must stay open

Fire stopping around Newbury: points for this area

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail. At about 53 miles from central London, Newbury is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

In a hotel such as Chequer's Hotel, which lies north of Newbury, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product. Shop fits on retail sites such as Parkway Shopping Centre (less than half a mile north of Newbury) can bring new services through fire-resisting walls between units, to be sealed with the specified product.

Newbury is about 15 miles west of Reading, in West Berkshire. Our applicators travel to Newbury for work on service penetrations, handled exactly as we handle every other area. Our West Berkshire coverage takes in 140 places, from busy centres to rural villages. There’s a separate page for Reading, about 15 miles away.

Postcode districts covered here: RG14, RG19, RG18 and RG20 for service penetrations. Streets here include Market Street, London Road and Donnington Square, and sites on any of them can send details for a fixed quote. Newbury sits on or close to the A4 and A339, which helps when planning parking and deliveries for the job. Nearby places we also cover include Greenham (1 mile south-east), Sandleford (1 mile south), Skinners Green (2 miles south-west), Wash Common (2 miles south-west) and Enborne (2 miles west) for service penetrations. Nearby towns on our patch include Thatcham (3 miles east), Burghfield Common (11 miles east), Hungerford (8 miles west), Fords Farm (13 miles east), Little Heath (12 miles east) and Calcot (12 miles east). Newbury is one of the busier places in West Berkshire, and its commercial and public buildings are all within our area.

Around Newbury

We work on buildings around Victoria Park, The Diamond Tap and St Bartholomew's School and the streets around them. There’s a railway station in Newbury itself: Newbury station. A little further out are Donnington Castle (1.6 miles north-west) and West Berkshire Community Hospital (1.5 miles east). Green spaces nearby include Audrey's Meadow.

What affects the price in Newbury

Before we quote, we look at:

  • Working within restricted access windows
  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • Whether old sealant has to be cut out first

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 and we will price your job on its own details.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Asbestos survey details if the building is older
  • What the building is and how it’s used
  • Specification clauses that apply
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or email a schedule or drawings.

Your questions answered

Can you seal penetrations in a hotel in Newbury after a refit?

Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Is hospital work, at somewhere like West Berkshire Community Hospital, something you do?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you fit around our working hours?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Aftercare for building managers

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Arrange inspection before areas are covered up
  • Record which product was used where
  • Keep general-purpose fillers away from compartment walls
  • Flag new cables with no seal around them

Never top up a fire seal with foam, ordinary silicone or filler. A repair should use the original product, installed the same way, or a new specification from the designer.

Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts, and the work runs in step with the M&E.

Leave it or put it right?

Fire stopping is a regular point raised at inspections and handover. Finding unsealed or improvised openings late can hold up a programme. In a town such as Newbury, a lot of buildings are older and have been altered over time, so joints between old and new are often the first to go. Resealing them early protects the building behind.

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