Fire stopping in Loose

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

Fire stopping in Loose, done properly

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. New cable runs, replaced pipework and extra data routes all punch holes in compartment walls, and they are easy to forget. Those on your schedule are closed with the specified product. Most enquiries involve old intumescent sealant that has split away and openings left by services added after handover, on service gaps in risers, small duct penetrations where the tested detail allows and pipe penetrations. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Loose, preparation and product choice get the time they need.

Around smaller places like Loose, 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 ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Where services cross fire walls in Loose

Loose has two care or nursing homes no more than 2 miles away. Where new services have gone through compartment walls in a care setting, the gaps need the specified product. Where that’s fire-rated sealant, we install it to the manufacturer’s tested detail. For England, the fire stopping of penetrations is dealt with in Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. We install whatever has been specified, to the product’s tested detail.

Colleges such as Kent Police College, 1.3 miles east of Loose, add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product. For a hospital such as The Somerfield Hospital (2.7 miles north of Loose), penetration sealing is typically phased ward by ward, with infection-control rules agreed first.

Loose is about 2 miles south of Maidstone, in Kent. We cover commercial sites throughout Loose, whether it’s a single job or part of a planned programme. Loose is one of 931 places we cover in Kent for service penetrations. London is covered too, some 32 miles away.

Anyone looking for fire stopping in ME15 and ME17 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. We cover commercial and managed buildings on Rosemount Close, Malthouse Hill and Old Loose Hill. Nearby places we also cover include Boughton Green (1 mile south-east), Boughton Monchelsea (1 mile south-east), Linton (1 mile south), Park Wood (2 miles east) and Shepway (2 miles north-east). Bigger towns within reach include Sittingbourne (12 miles north-east), Sevenoaks (15 miles west), Royal Tunbridge Wells (13 miles south-west), Gravesend (15 miles north-west), Tonbridge (11 miles west) and Northfleet (15 miles north-west).

Locally, jobs take us to sites close to Cornwallis Academy and The Chequers Inn and the streets around them. The closest station to Loose is East Farleigh station, about 1.8 miles north-west. Nearby you’ll also find Kent Fire Brigade Museum (1.4 miles north) and The Mall Maidstone (2.4 miles north).

When to bring in a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Surface by surface

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

Drylining partitions

Plasterboard partitions are tested as a specific construction. We check that the product’s detail covers that partition type and board thickness.

From enquiry to sign-off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Loose are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out.
  5. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

What we need from you

  • Agree which areas must stay open
  • Tell us your opening times and when work is allowed
  • Tell staff and tenants when we will be in

Advice

FAQs: Loose

Is Tovil Green Business Park, near Loose, within your area?

Yes, sites like Tovil Green Business Park are within our area, along with the rest of Loose. To start, just phone 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, which many sites require.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, though not damage or work by other trades.

Do you work in Loose?

Yes. Sites across Loose are covered.

What sets the cost

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

  • The size and state of each joint
  • How much there is to seal
  • Location, for remote and island sites
  • Phasing around occupants

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What to include in your enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Any dates the work must fit around
  • Where the site is, with the postcode
  • Drawings or a marked-up plan, if available
  • Whether an asbestos survey exists

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Why act early in Loose

Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable. Older rural buildings around Loose move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Common problems we fix in Loose

Some service penetrations were never sealed at all because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access typically bring them to light.

Common reasons buildings call us in:

  • Openings left by services added after handover
  • Non-fire-rated filler around services
  • Penetration schedules that need working through
  • Fire sealant pulled out of the opening

For a building at a site such as Tovil Green Business Park, 1.6 miles north of Loose, a check of penetration seals after each fit-out is good practice.

What your quote should include

  • How they handle RAMS and site documents
  • How joint depth will be controlled
  • What level of public liability insurance do they hold?
  • Is the sealant right for the movement and the substrate?
