Fire stopping in Midgham: the local picture

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. Either way, we install the specified product to its tested detail. At about 48 miles from central London, Midgham is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Hospital estates such as West Berkshire Community Hospital (3.8 miles west of Midgham) are divided into fire compartments, and any service penetration through them should be sealed to the specified, tested detail. Holiday works at schools like Bucklebury C.E. Primary School often leave service openings to seal before pupils return.

Midgham is about 2 miles east of Thatcham, in West Berkshire. We cover commercial sites throughout Midgham, for single jobs and planned programmes alike. 140 places across West Berkshire fall within our area, including Midgham. Our Reading page has more on work in that area, about 10 miles away.

If you need fire stopping in RG7, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Buildings on Birds Lane, School Hill and Church Hill are within our area for service penetrations. Just outside Midgham, we also work in Upper Bucklebury (1 mile north-west), Thatcham (2 miles west), Cold Ash (3 miles north-west), Ashmore Green (3 miles north-west) and Frilsham (4 miles north). Further afield, our area takes in Newbury (5 miles west), Burghfield Common (6 miles east), Speenhamland (5 miles west), Hungerford (13 miles west), Fords Farm (8 miles east) and Little Heath (8 miles north-east).

Local landmarks in Midgham

We work on buildings around Coach & Horses pub and Kennet School and the streets around them. The nearest railway station is Midgham station, roughly 1.2 miles east. Other landmarks nearby include Old Chapel Textile Centre (3.8 miles south-west) and Yattendon Castle (4.5 miles north). The countryside around Midgham includes Thatcham Reed Beds.

Fire stopping for commercial buildings in Midgham

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We hold no third-party fire-stopping installer certificate. We install the specified fire-rated sealant to its tested detail, and our workmanship carries a 12-month guarantee. We work on pipe penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the usual reasons a site gets in touch are builders’ foam or ordinary silicone in compartment walls and snag lists that include open service penetrations. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Midgham is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Barn and farm-building conversions near places like Midgham often combine new partitions with old walls. Where a pipe or cable passes through a fire-resisting wall, the seal must match the tested detail: product, substrate, gap and depth.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email the details over and we will come back to it.

When to bring in a specialist

Some joints are best left to specialists: 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.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be any of the following:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Reviewing a building’s overall fire safety
  • Walls or floors that aren’t fire-resisting to begin with

If you are not sure, just phone 01277 525 020 or email a schedule or drawings and we will give you a straight answer.

Surfaces we seal

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

Common problems we fix in Midgham

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.

What tends to prompt an enquiry:

  • Openings found when ceilings come down for a refit
  • Snag lists that include open service penetrations
  • Fire seals cut back for extra cables and never reinstated
  • Open linear gaps along the top of fire-resisting walls

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

What your quote should include

  • Will RAMS and insurance details be available?
  • Which product they’ll use, and why it suits the joint
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

Quoting for work in Midgham

These are the things that shape the price:

  • Whether old sealant has to be cut out first
  • The total length or number of joints
  • The site’s rules and procedures
  • Access and working height

Pricing service penetrations depends on how many there are, their condition and the access. Call for a quote.

Before you send an enquiry

Diagnosis starts before we arrive. Let us know:

  • Any specification or named product
  • The type of building and who uses it
  • Asbestos survey details if the building is older
  • When you need the work done

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Midgham can form part of a wider programme.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Common questions from Midgham clients

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

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work at a site such as Thatcham Business Village, by Midgham?

Yes. We cover Midgham and the area around it, including industrial estates, business parks and retail parks such as Thatcham Business Village. A few photographs and the unit address let us price the work.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Do you hold third-party fire-stopping installer certification?

No. We are not members of a third-party fire-stopping installer scheme. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we are not the right fit for that package.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you certify or sign off fire stopping?

No. Sign-off isn’t ours to give, and we don’t hold a third-party installer certificate. We work to the specification and the manufacturer’s installation guidance.

Diagnose, treat, sign off

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For a building around Midgham, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Tell us your opening times and when work is allowed
  • Let building users know which areas are affected
  • Flag any permit to work we will need

Request a quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to speak to us on 01277 525 020 or email drawings and photos with what you know.
