Fire stopping for Sedlescombe sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Approving the work on behalf of building control
  • Walls or floors that aren’t fire-resisting to begin with
  • Writing the fire-stopping specification

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

Surfaces we seal

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

About our fire stopping in Sedlescombe

Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal, not a rule of thumb. If you have head-of-wall gaps with no fire seal and seals that don’t match their tested detail, we can help, on pipe penetrations, joints between fire-resisting walls and floors and linear gaps at wall heads alike. Facilities teams, main contractors and managing agents in Sedlescombe tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural conversions around Sedlescombe can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Common questions from Sedlescombe clients

How does the move away from BS 476 affect penetration seals in Sedlescombe?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Will you take on work at estates like Marley Lane Business Park, close to Sedlescombe?

Yes. We cover Sedlescombe and the area around it, including industrial estates, business parks and retail parks such as Marley Lane Business Park. Photos and a short description are enough for a first look.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How do you deal with asbestos in old sealant?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Can staff carry on working while you are here?

Usually, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Fire stopping around Sedlescombe: what changes locally

In England, Approved Document B covers fire stopping of 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. Several hotels sit less than 2 miles from Sedlescombe. 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.

Wherever services are added at a hospital such as Conquest Hospital, 3.8 miles south of Sedlescombe, the compartment line has to be made good with the specified product. Hotels like Brickwall Hotel (under half a mile south-west of Sedlescombe) are refurbished in phases, and each phase can open up compartment walls. In a building such as The Parish Church of St John the Baptist, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Sedlescombe is about 5 miles north of Hastings, in East Sussex. Anywhere in TN33, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 308 places across East Sussex fall within our area, including Sedlescombe. Sites around Brighton have their own page, about 30 miles away.

Anyone looking for fire stopping in TN33 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. For a building on The Street, Orchard Way and Park Shaw or nearby, we can quote for service penetrations. Close to Sedlescombe, our area also takes in Whatlington (1 mile west), Kent Street (2 miles south), Swaile's Green (2 miles north), Cripp's Corner (2 miles north) and Telham (2 miles south-west). Bigger towns within reach include Eastbourne (15 miles south-west), Hastings (5 miles south), Bexhill-on-Sea (7 miles south-west), Hailsham (13 miles west), St Leonards (6 miles south) and Polegate (15 miles south-west).

Around Sedlescombe

The nearest railway station is Battle station, roughly 2.3 miles south-west of the centre. Well-known places in the area include Nortons Farm Museum (1.3 miles south) and Conquest Hospital (3.8 miles south). Not far away are Senlac Hill and Church Wood and Robsack Wood.

Different surfaces, different methods

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area and tell you about openings outside the list.

Plastic pipes

Plastic waste pipes through slabs come up often. Whether sealant alone is acceptable depends entirely on the tested detail, and we’ll never swap a specified collar for sealant.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • File the specified details where the next contractor can find them
  • Don’t let anyone top up a fire seal with the wrong product
  • Include service cupboards in routine inspections

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t, so check the product data first.

A simple record of seal locations and products helps. When a new service goes through, everyone knows which product and detail to match, and it helps at inspections.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically 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. Smaller jobs around Sedlescombe can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. First we go through the drawings, schedule or specification for the seals.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Getting the site ready

  • Let building users know which areas are affected
  • Make sure the joints can be reached
  • Arrange parking or a loading space

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What sets the cost

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

  • Which sealant the job calls for
  • How much there is to seal
  • Travel to remote or island sites
  • How much existing material needs removing

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Asbestos survey details if the building is older
  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back
  • The type of building and who uses it

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