Fire stopping near Tide Mills

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Reviewing a building’s overall fire safety
  • Construction that lacks the fire resistance the seal relies on
  • Signing off or certifying a building’s fire stopping

Not sure which it is? You can phone 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

What we seal

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

Fire stopping for commercial buildings in Tide Mills

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate and we’d rather say that up front. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. If you have fire-stopping items raised at inspection or handover and fire stopping installed outside its tested range, we can help, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Tide Mills, preparation and product choice get the time they need.

Smaller places such as Tide Mills 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.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Questions we’re asked in Tide Mills

Could you schedule work at a campus like University of Brighton for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Let us know which documents your site asks for, and we will confirm them alongside the quote.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

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.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

Can the building stay open while you work?

Yes, as long as we plan it. Tell us your site hours and access windows and we will plan around them.

Cost factors for service penetrations

These are the things that shape the price:

  • Distance, for remote addresses
  • Any access equipment needed
  • Joint width, depth and condition
  • The product specified

The product called for affects the cost, and so does the preparation. Access, phasing and site rules also count.

Sending details for a quote

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

  • The postcode of the building
  • When you need the work done
  • Access details, including height
  • Any specification or named product

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, phone 01277 525 020 or use the quote form.

Doing it in-house

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a single visit for a short list of penetrations, or a phased programme for a whole building. Jobs in and around smaller places like Tide Mills are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. The specification and schedule come first, so we know which details apply.
  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. We tell you about openings that need a different product.

Before we start on site

  • Let building users know which areas are affected
  • Point out parking and an unloading spot
  • Confirm the product named in the specification

Looking after the joints

After handover, these steps help:

  • Check risers and ceiling voids after each round of works
  • Arrange inspection before areas are covered up
  • Keep product data and details in the fire safety file
  • Treat an open penetration as a priority repair

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, by someone who knows the system.

Specify fire stopping early on refits, not as an afterthought. The designer can then choose details that suit the services planned, and installation follows the programme.

Penetration seals near Tide Mills

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Tide Mills is about 50 miles from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

For a unit at a site such as Newhaven Industrial Park, 0.6 miles to the north-west of Tide Mills, new power or data runs between office and warehouse can breach a compartment wall. In a building such as Church of St Andrew, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Common problems we fix in Tide Mills

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Clients usually get in touch after noticing something like this:

  • Snag lists that include open service penetrations
  • Seals disturbed by maintenance and left open
  • Service penetrations left open after M&E works
  • Open linear gaps along the top of fire-resisting walls

Theatres, wards and plant rooms at sites like Chailey Heritage Marine Hospital, under half a mile south-west of Tide Mills, all have compartment walls crossed by services.

Questions to ask before you book

  • Will RAMS and insurance details be available?
  • Their pre-qualification and accreditations
  • How they’ll work around occupants
  • Will failed sealant be removed rather than covered?
