Fire stopping near Greatstone-on-Sea

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

Fire stopping in Greatstone-on-Sea, done properly

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required. What we bring is careful installation of the specified sealant, to the maker’s guidance. Most enquiries involve unsealed openings around new pipes and cables and fire-rated sealant that has cracked or shrunk back, across pipe penetrations, cable penetrations and small duct penetrations where the tested detail allows. One point of contact handles commercial sealant work in Greatstone-on-Sea from the first photos to the final walk-round, whether it’s one building or several.

A job near Greatstone-on-Sea is normally 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.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Smaller jobs around Greatstone-on-Sea can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Old or wrong materials are cut out.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Let building users know which areas are affected
  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Leave it or put it right?

An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. Halls, stores and units around places like Greatstone-on-Sea may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The price depends on the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

Compartments and services around Greatstone-on-Sea

Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Our part stays the same: the specified product, installed to its tested detail. At about 58 miles from central London, Greatstone-on-Sea is within reach of the capital. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Where a unit on an estate such as Peak Industrial Park, 2.2 miles to the south-west of Greatstone-on-Sea, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail. In a school such as Greatstone Primary School, fire-rated sealant goes in around service penetrations where it is specified. In a building such as St Peter's, any service penetration through a fire-resisting wall should be sealed to the specified detail.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Writing the fire-stopping specification
  • Fire doors, dampers or other fire safety equipment
  • Large openings beyond what any sealant detail covers

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly before you book.

Joints and surfaces we work on

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

What the job involves on each surface

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.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening.

Your questions answered

Is Greatstone-on-Sea too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you work in a care home in Greatstone-on-Sea without moving residents out?

Yes. Care settings are planned area by area, at times agreed with the home. Noise and disruption are kept to a minimum.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Can you work to our specification?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.

Will you sign off the seals for us?

No. Sign-off belongs to the designer or building control, not the installer. We will confirm the product and detail installed, and you can tell us what other records you need at quote stage.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Do you work in Scotland as well as England?

Scotland sets its own building regulations, with Technical Handbooks, and England uses Approved Document B. Wherever the site is, our work follows the specification and the tested detail.

Work for main contractors and building owners

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Site staff or a sealant specialist?

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
