Common questions from High Salvington clients

Can you seal around new services in a hotel near High Salvington?

Yes, where fire-rated sealant is the specified product. It goes in to the manufacturer’s tested detail for the wall or floor and the services passing through, and we will tell you if the detail calls for a collar, wrap or batt instead.

How does the removal of BS 476 from Approved Document B affect fire-rated sealing in High Salvington?

From 2 September 2029, Approved Document B drops its BS 476 references in favour of BS EN 13501-2 classification, with transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Will your applicators have CSCS cards?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

Do you guarantee your work?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Is High Salvington in your area?

Yes. We take on work across High Salvington, and the same phone number covers every area.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Fire stopping in High Salvington, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it, matching the product and detail it names. Where there isn’t one, the designer or fire engineer needs to set one first. We work on small duct penetrations where the tested detail allows, linear gaps at wall heads and pipe penetrations, and what we are called in for most is unsealed joints where partitions meet the slab and fire sealant pulled out of the opening. Looking for mastic applicators who cover High Salvington? We’ve been sealing commercial buildings since 2005.

Buildings in a smaller place such as High Salvington that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Specified fire-rated sealant goes around new services there, built to match the manufacturer’s detail.

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 spell out the cover before we begin.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. For a site in High Salvington, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We start with your penetration schedule, drawings or specification.
  2. We plan the sequence of floors, risers and voids with you.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out so the seal starts clean.
  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

  • Tell us your opening times and when work is allowed
  • Send asbestos survey details if the building is pre-2000
  • Make sure the joints can be reached

Related advice

Do you need fire stopping in High Salvington?

Physical damage is another reason seals stop doing their job. Seals get knocked during maintenance, cut back to add a cable or pulled out when services are swapped and the opening isn’t always resealed.

Typical triggers for a call:

  • Hidden openings found during inspections
  • Non-fire-rated filler around services
  • Fire-rated sealant that has cracked or shrunk back
  • Damaged fire seals in risers and voids

Office fit-outs on sites such as Gosling Croft Business Centre (to the west of High Salvington) add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Questions to ask before you book

  • What site paperwork they can supply
  • Whether primer will be used where the manufacturer specifies it
  • How they’ll work around occupants
  • What level of public liability insurance do they hold?

Questions to ask before you appoint anyone

Different surfaces, different methods

Small ducts

We seal around ducts only within what the tested detail covers. Dampers and ductwork systems themselves are outside our work.

Risers and ceiling voids

Service risers and the voids above ceilings are where openings collect. Access is often tight, so we agree it with you in advance.

Honest limits

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Signing off or certifying a building’s fire stopping
  • Openings that need collars, wraps, batts or boards rather than sealant
  • Writing the fire-stopping specification

Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly before you book.

Joints and surfaces we work on

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

Looking after the joints

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Settle who seals which penetrations at the start of a project
  • Brief every trade that openings they make must be sealed
  • Check risers and ceiling voids after each round of works
  • Get seals inspected before ceilings and boxing close

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned, and installation follows the programme.

Compartment walls and floors in High Salvington

A 2-mile radius around High Salvington takes in a number of hotels. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. High Salvington is about 47 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls, and the gaps need sealing with the specified product.

Halls and meeting rooms at places like St Peter sometimes gain new services, and any compartment wall crossed needs the specified seal. At a healthcare site like Goring Hall Hospital, 2.8 miles to the south-west of High Salvington, new services through compartment walls are a constant, and each needs the specified seal.

Site staff or a sealant specialist?

There’s also the paperwork. 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.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
