Need fire stopping in Hadlow?

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

Site staff or a sealant specialist?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Fire stopping in Hadlow

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. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you are dealing with openings found when ceilings come down for a refit and head-of-wall gaps with no fire seal, we can help, whatever the surface. One point of contact handles commercial sealant work in Hadlow from the first photos to the final walk-round, whether it’s one building or several.

For a smaller site near Hadlow, we plan to do all the penetrations in one go, so send the specification and photos first. Design and sign-off belong to the designer or building control; we install what’s specified.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Fire-rated sealing for Hadlow buildings

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. What we install is set by the specification, and it goes in to the tested detail. Hadlow lies roughly 26 miles out from central London. Business park offices in the commuter belt are refitted as tenants change, and each fit-out adds services through compartment walls.

At a university such as University of Kent - Tonbridge, which lies south-west of Hadlow, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. For a hospital such as Tonbridge Cottage Hospital, which lies south-west of Hadlow, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. Industrial units on estates such as The Alders Industrial Estate (to the north-east of Hadlow) often separate offices from warehouse space with fire-resisting walls, and new services through them need the specified seal.

Hadlow is about 3 miles north-east of Tonbridge, in Kent. We cover Hadlow and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Kent, 931 places are covered, including Hadlow. There’s a separate page for London, about 26 miles away.

Commercial sites across TN11 are covered for service penetrations. Buildings on The Square, High Street and Brookfields are within our area. If your building is just outside Hadlow, we cover Pittswood (1 mile west), Goose Green (1 mile north-east), Golden Green (1 mile south), Parker's Green (1 mile south-west) and Barnes Street (1 mile south-east). Bigger towns within reach include Maidstone (9 miles east), Sevenoaks (7 miles north-west), Royal Tunbridge Wells (7 miles south-west), Gravesend (14 miles north), Tonbridge (3 miles south-west) and Northfleet (14 miles north).

What’s near Hadlow

We work on buildings around Hadlow Rural Community School, Hadlow College and The Rose & Crown pub and the streets around them. Hadlow’s nearest station is Beltring station, about 3.3 miles south-east of the centre. A little further out are Hadlow Tower museum (under half a mile south-east) and Tonbridge Cottage Hospital (4.3 miles south-west). Green spaces nearby include Barden Lake and Tudeley Woods RSPB reserve.

What sealant work can’t fix

Some faults sit outside our scope, and we say so rather than covering them up:

  • Large openings beyond what any sealant detail covers
  • Construction that lacks the fire resistance the seal relies on
  • Issuing fire ratings or certificates for seals

If you are not sure, just give us a call on 01277 525 020 or use the quote form and we’ll give you a straight answer.

Joints and surfaces we work on

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

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Record which product was used where
  • Get seals inspected before ceilings and boxing close
  • Make fire stopping part of every scope that crosses a fire-resisting wall

After every round of M&E works, check that the openings created have been sealed. Building it into each contractor’s sign-off keeps the walls intact.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.

Cost factors for service penetrations

These are the things that shape the price:

  • Quantities, in metres or numbers
  • Location, for remote and island sites
  • Working within restricted access windows
  • Specialist products, such as fire-rated or hygienic sealants

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Details that help us quote

We can often quote from photos and a few details. It helps to include:

  • A wide shot and a close-up of the area
  • Any dates the work must fit around
  • The asbestos register, for older buildings
  • Specification clauses that apply

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Your questions answered

Is Hadlow too small for you to travel to?

Not at all. Hadlow is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Can you work at a site such as The Alders Industrial Estate, by Hadlow?

Yes. Our area takes in Hadlow and its surroundings, with estates and business parks such as The Alders Industrial Estate included. Photos and a short description are enough for a first look.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

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’ll confirm the colours available for the specified product.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Hadlow need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Unsuitable fillers and loose debris are taken out of each opening.
  4. Mineral wool or other backing goes in wherever the detail asks.
  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.

Before we start on site

  • Share the asbestos register for older buildings
  • Flag any permit to work we will need
  • Share your working hours and any access restrictions
