Fire stopping across Galleywood

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

How we handle fire stopping in Galleywood

A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. If you have service penetrations left open after M&E works and fire seals cut back for extra cables and never reinstated, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Galleywood it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places like Galleywood, many commercial buildings are conversions or extensions of older ones, so the wall or floor a service passes through isn’t always what the drawings assume. The right product depends on the wall or floor and the services passing through, and we’ll tell you if the detail calls for something other than sealant.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Why deal with it now?

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Why appoint us

  • Fully insured, including public liability cover
  • A fixed quote before work starts
  • CHAS accredited
  • Work to your specification and the manufacturer’s guidance

Quoting for work in Galleywood

A fixed quote reflects the actual work. It allows for:

  • The size and state of each joint
  • Quantities, in metres or numbers
  • How accessible the joints are
  • Working within restricted access windows

What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • Whether an asbestos survey exists
  • Any dates the work must fit around
  • A wide shot and a close-up of the area
  • The postcode of the building

For a fixed quote, call 01277 525 020 or email us, telling us the site location and the nature of the job. Our quote form is another easy route.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • Check risers and ceiling voids after each round of works
  • Ask which product is in place before decorating
  • Settle who seals which penetrations at the start of a project
  • Brief every trade that openings they make must be sealed

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.

From enquiry to sign-off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes anything from one day to a planned run of visits, depending on the number of seals and the access, and we clear our waste as we work. Work in places the size of Galleywood is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  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.

Getting the site ready

  • Make sure the joints can be reached
  • Tell us your opening times and when work is allowed
  • Explain the parking and delivery arrangements

FAQs: Galleywood

What happens to BS 476 references for fire stopping in Galleywood?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Does your area include sites such as Beehive Business Centre, near Galleywood?

Yes. We cover Galleywood and the area around it, including industrial estates, business parks and retail parks such as Beehive Business Centre. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.

Service penetrations in Galleywood buildings

In England, Approved Document B covers fire stopping of 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. Galleywood lies roughly 28 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

For a site team at a college like Chelmsford College Princes Road Campus (1.6 miles north of Galleywood), fire-rated sealing is best scheduled after the summer works. In a building such as Church of St Michael and All Angels, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a building at a site such as Beehive Business Centre, which lies north of Galleywood, a check of penetration seals after each fit-out is good practice.

Galleywood is about 3 miles south of Chelmsford, in Essex. Across the CM2 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Essex, 644 places are covered, including Galleywood. We also cover London, some 28 miles away.

Anyone looking for fire stopping in CM2 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. If your site is on The Street, Attwoods Close and Markland Close or close by, send details and we’ll quote for service penetrations. Just outside Galleywood, we also work in Margaretting Tye (2 miles south-west), Margaretting (3 miles west), Stock (3 miles south-west), Ramsden Heath (4 miles south) and Downham (4 miles south). Further afield, our area takes in Chelmsford (3 miles north), Basildon (9 miles south), Braintree (13 miles north), Brentwood (9 miles south-west), Maldon (9 miles east) and Canvey Island (13 miles south).

Local landmarks in Galleywood

In Galleywood, that means premises near Great Baddow High School, Galleywood Common and The Eagle Public House and the streets around them. The nearest railway station is Chelmsford station, about 2.6 miles north of the centre. A little further out are Peter Edwards Museum And Library (2.3 miles north) and Baddow Hospital (1.3 miles east). The countryside around Galleywood includes Hanningfield Reservoir.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Writing the fire-stopping specification
  • Fire risk assessments, a job for a competent assessor
  • Gaps in walls that were never built as compartment walls

If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

What we seal

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

Building owners, agents and FMs in Galleywood

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Galleywood can form part of a wider programme.
