Compartment walls and floors in Hardham

Fire stopping of openings and penetrations in England falls under 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. Either way, we install the specified product to its tested detail. A 2-mile radius around Hardham takes in several hotels. Bedroom-to-corridor walls in hotels are normally fire-resisting, so new cabling or pipework through them has to be sealed to the tested detail.

Hotels like Chequers Hotel, 0.9 miles north-east of Hardham, are refurbished in phases, and each phase can open up compartment walls. On estates like Station Approach Industrial Estate, 0.7 miles to the north-east of Hardham, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal.

Hardham is about 10 miles north of Littlehampton, in West Sussex. Across the RH20 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 373 places in West Sussex, from busy centres to rural villages. Sites around Brighton have their own page, roughly 19 miles from Hardham.

If you need fire stopping in RH20, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Fire stopping for commercial buildings in Hardham

For main contractors, our fire stopping package slots in after the M&E trades have finished in an area. To price a package, phone 01277 525 020 or email the details over with the schedule or marked-up drawings. Tell us what records you need and we’ll confirm with the quote. If you have damaged fire seals in risers and voids and openings left by services added after handover, we can help, on linear gaps at wall heads, pipe penetrations and service gaps in risers alike. A specialist sealant contractor works differently from a general builder: in Hardham, that means joint design, primers and backing rod as standard.

Smaller places such as Hardham still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

What sealant work can’t fix

We check first that sealant really is the fix. It isn’t the answer for:

  • Issuing fire ratings or certificates for seals
  • Reviewing a building’s overall fire safety
  • Writing the fire-stopping specification

If you are not sure, just speak to us on 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Where we work in Hardham

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

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes anything from one day to a planned run of visits, depending on the number of seals and the access, and our waste is bagged and taken away as we go. For work around Hardham, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  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.

Preparing the site

  • Send any specification or drawings in advance
  • Warn occupants and staff about the work
  • Clear stock, furniture or equipment away from the joints

Advice

Aftercare for building managers

After handover, these steps help:

  • Foam or ordinary sealant is never a fire-seal repair
  • Ask the designer to confirm details early on refits
  • Arrange inspection before areas are covered up
  • Make fire stopping part of every scope that crosses a fire-resisting wall

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

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Signs you need fire stopping in Hardham

A common fault is a product that was never fire-rated in the first place: expanding foam or a general-purpose sealant pushed into a gap to tidy it. The opening looks sealed but has no fire test evidence behind it, so it has to come out.

Site and facilities staff are often the first to spot these:

  • Snag lists that include open service penetrations
  • Fire stopping installed outside its tested range
  • Head-of-wall gaps with no fire seal
  • Damaged fire seals in risers and voids

For a school such as St James' CofE Primary School, penetration sealing fits best at the end of the summer works.

What your quote should include

  • How the joint faces will be prepared and primed
  • Proof of insurance
  • Who will actually carry out the work
  • How joint depth will be controlled

How to choose a sealant contractor

Owners, agents and contractors

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. Keys, access and contacts can be agreed in advance.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.

FAQs: Hardham

Do you work on fire-rated sealing in hotels in Hardham?

Yes, to the specification and the product’s tested detail. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we’ll tell you if the detail calls for a collar, wrap or batt instead.

Does your area include sites such as Station Approach Industrial Estate, near Hardham?

Yes, sites like Station Approach Industrial Estate are within our area, along with the rest of Hardham. Photos and a short description are enough for a first look.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Will you come and look before quoting?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Can you handle several sites?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

What the job involves on each surface

Linear joints

Head-of-wall joints often have to absorb slab deflection. The specified product and backing for that movement are what goes in.

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
