Fire stopping in Warnford

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

After the work

To get the most from the new sealant:

  • Settle who seals which penetrations at the start of a project
  • Get seals inspected before ceilings and boxing close
  • Report damaged or disturbed seals as soon as they’re spotted
  • File the specified details where the next contractor can find them

Store the specified product details somewhere the next contractor can find them. Anyone resealing later needs to know which product and detail were used.

Write fire stopping into the scope of any work crossing a compartment wall or floor. That way the opening is sealed while the trade and access are still there instead of being left for someone else.

Fire stopping in Warnford, done properly

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on cable penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads, and the failures we’re asked to look at most are fire-stopping items raised at inspection or handover and unsealed openings around new pipes and cables. One point of contact handles commercial sealant work in Warnford from the first photos to the final walk-round, for single jobs and planned programmes alike.

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

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Fire-rated sealing for Warnford buildings

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. What we install is set by the specification, and it goes in to the tested detail. Warnford is about 56 miles from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

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

Warnford is about 8 miles west of Petersfield, in Hampshire. Businesses, contractors and managing agents in Warnford use us for work on service penetrations, as part of our coverage of Hampshire. We work across 723 places in Hampshire, large and small. There’s a separate page for Southampton, roughly 14 miles from Warnford.

Signs you need fire stopping in Warnford

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 and later need putting right.

Typical triggers for a call:

  • Old intumescent sealant that has split away
  • Service penetrations left open after M&E works
  • Hidden openings found during inspections
  • Damaged fire seals in risers and voids

Around Warnford, we install fire-rated and intumescent sealant to the product’s tested detail wherever it is the specified product.

Before you book anyone

  • Will failed sealant be removed rather than covered?
  • What site paperwork they can supply
  • What the guarantee covers, and for how long
  • How they’ll work around occupants

Our contractor checklist

When it isn’t the sealant

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

  • Writing the fire-stopping specification
  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals

If you’re not sure, just call 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.

Where we work in Warnford

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

Warnford: questions and answers

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

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is Warnford too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Can staff carry on working while you are here?

In most cases, yes. We phase the work so most of the building stays in use.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work 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. Jobs in and around smaller places like Warnford are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. The specification and schedule come first, so we know which details apply.
  2. We plan the sequence of floors, risers and voids with you.
  3. Each opening is checked for wall or floor type, service, gap and depth.
  4. Foam, ordinary sealant and debris come out first.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Before we start on site

  • Tell us your opening times and when work is allowed
  • For older buildings, check the asbestos register before work
  • Flag any permit to work we’ll need

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
