Your questions answered

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

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.

Is Frogham too small for you to travel to?

No. Places such as Frogham are covered as much as the big towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Do you guarantee your work?

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

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Do you have public liability insurance?

Yes. We’re fully insured, and the certificate can go with your quote.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Fire stopping for commercial buildings in Frogham

A lot of fire-stopping work comes after M&E installation, a refit or a tenant fit-out. Each new cable, pipe or data route cut through a fire-resisting wall leaves an opening behind, and they are easy to forget. We close the openings listed on your schedule, using the specified sealant and detail. If you are dealing with fire-stopping items raised at inspection or handover and seals that don’t match their tested detail, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Frogham it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

A job near Frogham is usually planned around one visit, so send the specification and photographs first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Compartments and services around Frogham

Approved Document B is the English guidance that covers fire stopping around 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. Central London is about 61 miles from Frogham. Office refits around the commuter belt bring new cabling through fire-resisting walls, and the gaps need sealing with the specified product.

Where a unit on an estate such as Aylesham Industrial Estate (1.8 miles north-west of Frogham), has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. For a building such as Church of St Nicholas, new heating or data runs are the usual reason penetrations need sealing.

Frogham is about 6 miles north-west of Dover, in Kent. We send applicators to Frogham for service penetrations. We work across 931 places in Kent, large and small. For work in that direction, see our London page (61 miles or so).

Close to Frogham, our area also takes in Barfrestone (1 mile south-east), Snowdown (1 mile north-west), Nonington (1 mile north), Woolage Village (1 mile west) and Elvington (1 mile east).

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • How accessible the joints are
  • Which sealant the job calls for
  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

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

  • Clear photographs of the problem areas
  • Whether an asbestos survey exists
  • Your programme or deadline
  • Specification clauses that apply

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or send photos by email to discuss it first.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and we clear our waste as we work. Jobs in and around smaller places like Frogham are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. We start with your penetration schedule, drawings or specification.
  2. Access, permits and the order of areas are agreed with the site team.
  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. Backing and fire-rated sealant are installed to the detail and tooled.
  6. We tell you about openings that need a different product.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints

Commercial clients in Frogham

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

When to call us in Frogham

Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.

Common reasons buildings call us in:

  • Open linear gaps along the top of fire-resisting walls
  • Openings found when ceilings come down for a refit
  • Seals disturbed by maintenance and left open
  • Non-fire-rated filler around services

Holiday works at schools like Nonington Church of England Primary School often leave service openings to seal before pupils return.

Before you book anyone

  • Do they follow the manufacturer’s priming guidance?
  • Whether old or failed sealant will be cut out, not overlaid
  • What the guarantee covers, and for how long
  • Whether their applicators hold CSCS cards

Our contractor checklist

Why it’s worth doing now in Frogham

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these. Older rural buildings around Frogham move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Why choose Mastic Doctor in Frogham

  • Constructionline member for supplier checks
  • One contact handling all your sites
  • Our applicators hold CSCS cards
  • Joints cleaned back to sound surfaces

Looking after the joints

Cleaning and maintenance staff play a part too. Share these points with them:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Include service cupboards in routine inspections
  • Foam or ordinary sealant is never a fire-seal repair
  • Check with the data sheet before painting over fire sealant

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.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match.
