Fire stopping in Great Tey

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

Cost factors for service penetrations

A fixed quote reflects the actual work. It allows for:

  • Removal of failed or old sealant
  • Joint width, depth and condition
  • Any access equipment needed
  • Quantities, in metres or numbers

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

What to include in your enquiry

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

  • How the joints are reached, and at what height
  • The type of building and who uses it
  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email a schedule or drawings to discuss it first.

Fire stopping for commercial buildings in Great Tey

Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. The enquiries we see most involve openings left by services added after handover and openings found when ceilings come down for a refit, on linear gaps at wall heads, cable penetrations and pipe penetrations. Looking for mastic applicators who cover Great Tey? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Barn and farm-building conversions near places like Great Tey often combine new partitions with old walls. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

Fire-rated sealing for Great Tey buildings

At about 45 miles from central London, Great Tey is within reach of the capital. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal. Approved Document B is the English guidance that covers fire stopping around openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail.

Large healthcare estates like Halstead Hospital (5.7 miles north-west of Great Tey) change their services often, so penetration seals are worth checking after M&E work. For a building such as Church of St Barnabas, new heating or data runs are the usual reason penetrations need sealing. Offices at parks like Earls Colne Business Park, 2.9 miles west of Great Tey, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

Great Tey is about 5 miles south-east of Halstead, in Essex. We send applicators to Great Tey for service penetrations, handled exactly as we handle every other area. 644 places across Essex fall within our area, Great Tey among them. We also cover London, some 45 miles away.

Anyone looking for fire stopping in CO6 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Maintenance after handover

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Leave fire sealant to cure fully before covering it
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Ask the designer to confirm details early on refits
  • Record which product was used where

After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small; found late, it can be one of many.

Common questions from Great Tey clients

Is Great Tey off your patch?

Not at all. Great Tey is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you take on work at healthcare sites like Halstead Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Can you quote from photographs?

That depends on the size and complexity of the job. Simple work can often be priced from photographs, while larger or less clear jobs get a site visit first.

Will you write the fire-stopping specification?

No. The specification comes from your designer, fire engineer or building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.

Do the same rules apply to fire stopping in Scotland?

Our work covers Greater London, the South East and every Scottish council area. In Scotland, clause 2.1.14 of the non-domestic Technical Handbook says service penetrations should keep at least the fire resistance of the wall or floor, with proprietary products tested for the end use.

Is the work guaranteed?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

General trades versus a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

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.

Commercial clients in Great Tey

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

We work for building owners and managing agents on everything from one building to a spread of sites around Great Tey. One quote can cover more than one site, so there’s one set of paperwork to deal with.

How a job runs

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 Great Tey can be grouped with others nearby. You will have a fixed quote before work starts.

  1. First we go through the drawings, schedule or specification for the seals.
  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. We fit the backing the detail asks for, to the stated depth.
  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.

Getting the site ready

  • Have the specification and drawings to hand
  • Tell us what induction or permit system the site runs
  • Send your site hours and access windows

Get a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

Related advice

Leave it or put it right?

An unsealed opening affects more than fire safety: they also carry noise, draughts and smells between rooms. Sealing them to the specified detail deals with the fire risk first, and the other benefits follow. Around Great Tey, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
