Fire stopping for commercial buildings in Chidham

Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Other openings need collars, wraps, batts, pillows or boards. If the detail calls for something other than sealant, we say so rather than force sealant into it. If you’re dealing with openings found when ceilings come down for a refit and fire-stopping items raised at inspection or handover, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Chidham, preparation and product choice get the time they need.

For a smaller site near Chidham, we plan to do all the penetrations in one go, with the specification and photos sent in advance. Design and sign-off belong to the designer or building control; we install what’s specified.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

How a job runs

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. For a building around Chidham, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. Each opening is checked for wall or floor type, service, gap and depth.
  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.

Before we start on site

  • Explain the parking and delivery arrangements
  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Related advice

Building owners, agents and FMs in Chidham

If you look after buildings for someone else, 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, plus a 12-month guarantee.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

What sets the cost

A fixed quote reflects the actual work. It takes account of:

  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements
  • Working within restricted access windows
  • Location, for remote and island sites

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What we need to price the job

We can often quote from photographs and a few details. Please tell us:

  • Your programme or deadline
  • How the joints are reached, and at what height
  • Any specification or named product
  • The postcode of the building

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photos and a few notes.

What we can’t put right

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Reviewing a building’s overall fire safety
  • Gaps in walls that were never built as compartment walls
  • Openings that need collars, wraps, batts or boards rather than sealant

If you’re not sure, just phone 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Where we work in Chidham

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

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Looking after the joints

A few simple habits keep the new joints working:

  • Leave fire sealant to cure fully before covering it
  • Report damaged or disturbed seals as soon as they’re spotted
  • Keep product data and details in the fire safety file
  • Look above ceilings when tiles are lifted for other jobs

Once the seals are in, tell other trades they exist and must not be disturbed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open.

Questions we’re asked in Chidham

Can you work around term dates at a campus such as University of Chichester?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we will confirm them alongside the quote.

What does the BS 476 change mean for fire-rated sealant in Chidham?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is your workmanship covered by a guarantee?

Yes. Workmanship is guaranteed for 12 months on every job.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards.

How do I request a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or use the quote form. Include photos or drawings if you have them.

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.

Where services cross fire walls in Chidham

Four care or nursing homes sit less than 2 miles from Chidham. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. We install fire-rated sealant to the tested detail where it is specified. Central London is about 57 miles from Chidham. 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.

Halls and meeting rooms at places like The Parish Church of St Mary sometimes gain new services, and any compartment wall crossed needs the specified seal. On estates like Southfield Industrial Park. (1 mile east of Chidham), the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Hotels like Millstream Hotel, 0.8 miles to the east of Chidham, are refurbished in phases, and each phase can open up compartment walls.

Chidham is about 4 miles west of Chichester, in West Sussex. Anywhere in PO18, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.
