About our fire stopping in Eridge Green

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail. Site teams most often ask us about unsealed openings around new pipes and cables and builders’ foam or ordinary silicone in compartment walls, on cable penetrations, joints between fire-resisting walls and floors and service gaps in risers. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Eridge Green it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around smaller places like Eridge Green, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. If sealant is what the specification names, we install it around the services exactly as the maker’s detail sets out.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Aftercare for building managers

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Agree the fire-stopping specification before services go in
  • Get seals inspected before ceilings and boxing close
  • File the specified details where the next contractor can find them
  • Report damaged or disturbed seals as soon as they’re spotted

Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown and get them dealt with.

Keep a register of where seals are and what they are made of. It tells the next contractor exactly what to reinstate.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Eridge Green may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We read the specification, drawings or penetration schedule you send and raise any questions before we price.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  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. Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
  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

  • Tell us your opening times and when work is allowed
  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints

Your questions answered

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. The designer or fire engineer sets the specification, and we install the product to the manufacturer’s tested detail.

Is a hospital such as Tunbridge Wells Homeopathic Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Does weather matter for sealant work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Commercial clients in Eridge Green

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Honest limits

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Fire risk assessments, a job for a competent assessor
  • Issuing fire ratings or certificates for seals
  • Construction that lacks the fire resistance the seal relies on

If in doubt, call 01277 525 020 or email the details over and we will say what we think.

Joints and surfaces we work on

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

Common problems we fix in Eridge Green

On a busy project, programme pressure can mean fire stopping is rushed or left to whichever trade is closest. That is how unsuitable products and improvised details end up in compartment walls.

Look out for the following:

  • Damaged fire seals in risers and voids
  • Improvised or mixed-product fire seals
  • Unsealed penetrations discovered above suspended ceilings
  • Snag lists that include open service penetrations

In a building such as Holy Trinity Church, any service penetration through a fire-resisting wall should be sealed to the specified detail.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • Health and safety accreditation such as CHAS
  • Whether old or failed sealant will be cut out, not overlaid
  • How long is the guarantee, and what does it include?

Questions to ask before you appoint anyone

Surface by surface

Cables and cable bundles

New data and power cables are the most common breach we see. Openings around new cables are resealed to the detail.

Risers and ceiling voids

Risers and ceiling voids hold most of a building’s service penetrations. Access is often tight, so we agree it with you in advance along with any permits your site needs.

Fire stopping in Eridge Green: the local picture

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. Eridge Green lies roughly 31 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; the gaps need the specified seal.

On a hospital site such as Tunbridge Wells Homeopathic Hospital (2.8 miles north-east of Eridge Green), fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Residences at universities like Canterbury Christ Church University - Salomons (3.8 miles north of Eridge Green) have compartment walls that must be resealed whenever services change.

Eridge Green is about 3 miles south-west of Royal Tunbridge Wells, in East Sussex. Any commercial site in Eridge Green is covered, for single jobs and planned programmes alike.
