Fire stopping for businesses in Barns Green

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

After the work

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

  • Keep product data and details in the fire safety file
  • Include service cupboards in routine inspections
  • Get seals inspected before ceilings and boxing close
  • Ask which product is in place before decorating

Keep the product data and installation details with the building’s fire safety information. Anyone resealing later needs to know which product and detail were used.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.

About our fire stopping in Barns Green

We should be clear about what we do and don’t do. Deciding the specification sits with the designer, the fire engineer and building control. What we bring is careful installation of the specified sealant, to the maker’s guidance in Barns Green and nearby. Site teams most often ask us about fire-stopping items raised at inspection or handover and builders’ foam or ordinary silicone in compartment walls, across joints between fire-resisting walls and floors, linear gaps at wall heads and small duct penetrations where the tested detail allows. Searching for sealant specialists in Barns Green? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around smaller places like Barns Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Our workmanship is guaranteed for 12 months, in Barns Green as everywhere else we work. If our installation lets you down in that time, we return and fix it.

What happens if it’s left?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these, and the other benefits follow. Halls, stores and units around places like Barns Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

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

Barns Green: questions and answers

Will you take on work at estates like Southwater Business Park, close to Barns Green?

Yes. Estates, retail parks and business parks around Barns Green, Southwater Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is hospital work, at somewhere like Horsham Hospital, something you do?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Is fire stopping in Scotland covered by different guidance?

Our area runs from Greater London and the South East to every part of Scotland. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.

Do you design or specify fire stopping?

No, we don’t design fire stopping. With the designer’s details in hand, we can price the sealant elements.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

How much does the work cost?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or send details through our quote form with a description of the work.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

Fire stopping in Barns Green: the local picture

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. Our part stays the same: the specified product, installed to its tested detail. At about 35 miles from central London, Barns Green is within reach of the capital. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls, and the gaps need sealing with the specified product.

Offices at parks like Southwater Business Park, 2 miles east of Barns Green, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. For a school such as Barns Green Primary School, penetration sealing fits best at the end of the summer works. Theatres, wards and plant rooms at sites like Horsham Hospital, 4 miles north-east of Barns Green, all have compartment walls crossed by services.

Barns Green is about 4 miles south-west of Horsham, in West Sussex. We cover Barns Green, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Barns Green is one of 373 places we cover in West Sussex. There’s a separate page for Brighton, about 18 miles away.

When it isn’t the sealant

Some faults sit outside our scope, and we say so rather than covering them up:

  • Fire risk assessments, a job for a competent assessor
  • Construction that lacks the fire resistance the seal relies on
  • Designing or specifying fire stopping, which sits with the designer or fire engineer

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.

Where we work in Barns Green

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

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. If others near Barns Green need work, visits can be combined. You will have a fixed quote before work starts.

  1. We start with your penetration schedule, drawings or specification.
  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. Unsuitable material is removed and the opening cleaned first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. Anything outside the detail is reported to you rather than sealed.

Quoting for work in Barns Green

We price every job individually. The main factors are:

  • Working within restricted access windows
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • Any access equipment needed

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What we need to price the job

It doesn’t need to be a full survey. These details are enough to start:

  • Rough lengths or quantities, or drawings if you have them
  • The product your specification calls for
  • Clear photos of the problem areas
  • Access details, including height

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

Should maintenance staff do it?

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
