Fire stopping in Beckley

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

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Reviewing a building’s overall fire safety
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If in doubt, speak to us on 01277 525 020 or send details through our quote form and we’ll say what we think before you book.

Joints and surfaces we work on

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

How we handle fire stopping in Beckley

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. If you have expanding foam used as fire stopping and penetration schedules that need working through, we can help. For commercial sealant work in Beckley, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a smaller site near Beckley, we plan to do all the penetrations in one go, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

A 12-month guarantee applies to all our work. Should something we installed fail, give us a call on 01277 525 020 or email us and we will come back to it.

Should maintenance staff do it?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Beckley can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Mineral wool or other backing is fitted where required.
  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.

Before we start on site

  • Point out parking and an unloading spot
  • Agree which areas must stay open
  • Tell us what induction or permit system the site runs

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email a schedule or drawings.

Related advice

What we are called out for in Beckley

Plenty of openings were simply never closed. Inspections, refurbishments and ceiling access normally bring them to light.

What tends to prompt an enquiry:

  • Snag lists that include open service penetrations
  • Improvised or mixed-product fire seals
  • Openings found when ceilings come down for a refit
  • Damaged fire seals in risers and voids

For a building such as Church of the Assumption of the Blessed Virgin Mary, new heating or data runs are the usual reason penetrations need sealing.

Questions to ask before you book

  • How the joint faces will be prepared and primed
  • Proof of insurance
  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid

Choosing a commercial sealant contractor

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Get seals inspected before ceilings and boxing close
  • Ask the designer to confirm details early on refits
  • Report damaged or disturbed seals as soon as they’re spotted

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Look for cracks, unsealed new cables and gaps that have been enlarged.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

Where services cross fire walls in Beckley

For England, the fire stopping of penetrations is dealt with in Approved Document B. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Central London is about 51 miles from Beckley. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Residences at universities like Oxford Brookes University Marston Road Site (to the south-west of Beckley) have compartment walls that must be resealed whenever services change. Schools such as Beckley Church of England Primary School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.

Beckley is about 4 miles north-east of Oxford, in Oxfordshire. If you are looking for fire stopping in Beckley, we can help. Beckley is one of 423 places in Oxfordshire on our list for service penetrations.

Your questions answered

Is Beckley too small for you to travel to?

No. Places such as Beckley are covered as much as the big towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Can you work around term dates at a campus such as Oxford Brookes University Marston Road Site?

Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Will you sign off the seals for us?

No. Approval sits with the designer, principal designer or building control. We’ll confirm the products and details used and agree any further records when we quote.

Will fire-rated sealant work on every penetration?

No. It depends on the tested detail for that wall or floor and service. Collars, wraps, batts and boards exist for openings sealant doesn’t cover, and we’ll tell you when that applies.

How long does a typical visit take?

It depends on the scope, but the work normally takes a single visit for a short list of penetrations, or a phased programme for a whole building. For bigger or phased jobs, we will set out a timescale with the quote.

What happens if it’s left?

Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first. Older rural buildings around Beckley move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

A quote for service penetrations depends on quantities, condition and access. Call for a quote.
