Fire stopping in Sullington

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

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

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

About our fire stopping in Sullington

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. Most enquiries involve damaged fire seals in risers and voids and non-fire-rated filler around services, on service gaps in risers, cable penetrations and pipe penetrations. Whoever orders the work in Sullington, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Sullington, 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Compartments and services around Sullington

Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements.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 43 miles from central London, Sullington is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls.

Tenant changes at parks like Rock Business Park, 1.7 miles to the east of Sullington, bring new data and services, and openings through fire-resisting walls need the specified seal. In a building such as The Parish Church of St Mary, any service penetration through a fire-resisting wall should be sealed to the specified detail. For a hotel such as The Old Market Rooms The White Horse Hotel, 0.9 miles north-west of Sullington, penetration seals are worth checking after any refit or services upgrade.

Sullington is about 6 miles north of Worthing, in West Sussex. We cover Sullington and the rest of West Sussex, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 373 places in West Sussex, from busy centres to rural villages. For work in that direction, see our Brighton page.

If you need fire stopping in RH20, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. If your building is just outside Sullington, we cover Storrington (1 mile north-west), Heath Common (1 mile north-east), Washington (1 mile east), Rock (1 mile east) and Cootham (2 miles north-west). A short drive away, we cover Horsham (12 miles north-east), Worthing (6 miles south), Bognor Regis (14 miles south-west), Burgess Hill (14 miles east), Littlehampton (8 miles south-west) and Shoreham-by-Sea (9 miles south-east).

After the work

Keep the joints in good shape with a few simple steps:

  • File the specified details where the next contractor can find them
  • Keep general-purpose fillers away from compartment walls
  • Arrange inspection before areas are covered up
  • Brief every trade that openings they make must be sealed

Store the specified product details somewhere the next contractor can find them. It makes later repairs much easier to match.

Ask every contractor who works in risers or voids to report openings they create. Small habits like this stop openings building up.

When something else is needed

Being straight saves everyone time. New sealant won’t cure:

  • Fire doors, dampers or other fire safety equipment
  • Deciding what a wall or floor needs, which belongs to the designer
  • Signing off or certifying a building’s fire stopping

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think before you book.

What we seal

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

Questions we’re asked in Sullington

Is Sullington off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

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

Yes, where fire-rated sealant is the specified product. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How do I request a quote?

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

How many days will you need on site?

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

When can the area be used after sealing?

Curing time varies by product, and we confirm it on the day.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member.

For managing agents and facilities managers

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Cost factors for service penetrations

Each job is priced on its own details. The main factors are:

  • Joint width, depth and condition
  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • What the building is and how it’s used
  • The product your specification calls for
  • Photos of the joints, close up and from further back
  • Access details, including height

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, call the office on 01277 525 020 or use the quote form.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Sullington can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.

What we need from you

  • Arrange parking or a loading space
  • For older buildings, check the asbestos register before work
  • Flag any permit to work we will need
