Fire stopping near Hockley

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Site staff or a sealant specialist?

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

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

How we handle fire stopping in Hockley

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. Those on your schedule are closed with the specified product. The enquiries we see most involve fire sealant pulled out of the opening and service penetrations left open after M&E works, across service gaps in risers, cable penetrations and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Hockley first comes to us: we look at the rest while we’re there and tell you what we find.

In places the size of Hockley, fire-resisting walls and floors are found in schools, care homes, health centres and mixed-use buildings. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.

Work we carry out in Essex comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email the details over and we’ll come back to it.

When it isn’t the sealant

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Writing the fire-stopping specification
  • Issuing fire ratings or certificates for seals
  • Walls or floors that aren’t fire-resisting to begin with

Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we’ll tell you honestly.

What we seal

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

Leave it or put it right?

Open penetrations multiply: each new service adds to the list. A schedule that is dealt with regularly stays manageable. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What you get with us

  • Old sealant cut out, never sealed over
  • Workmanship guaranteed for 12 months

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Several jobs near Hockley can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. First we confirm the product and tested details named in the specification.
  2. We sort the openings by the detail each one needs.
  3. Improvised fillers and failed sealant are removed.
  4. Where the detail needs backing, it goes in at the stated depth.
  5. We gun the sealant in to the specified depth around each service and tool it.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Preparing the site

  • Tell us which areas need to stay in use
  • Clear stock, furniture or equipment away from the joints
  • Warn occupants and staff about the work

Getting a fixed quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or email the details over.

Penetration seals near Hockley

Approved Document B is the English guidance that covers fire stopping around openings and penetrations. From 2 September 2029, BS 476 references are being taken out of Approved Document B, leaving BS EN 13501-2 classification as the route, subject to the Government’s transitional arrangements. Either way, we install the specified product to its tested detail. Hockley is about 33 miles from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls; the gaps need the specified seal.

For a site team at a college like South Essex College Stephenson Road Campus, 2.6 miles south of Hockley, fire-rated sealing is best scheduled after the summer works. For a hospital such as Rochford Hospital, 2.4 miles to the south-east of Hockley, penetration sealing is usually phased ward by ward, with infection-control rules agreed first. Holiday works at schools like Greensward Academy often leave service openings to seal before pupils return.

Questions we are asked in Hockley

Could you schedule work at a campus like South Essex College Stephenson Road Campus for the vacation?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Airport Business Park, near Hockley, within your area?

Yes. Our area takes in Hockley and its surroundings, with estates and business parks such as Airport Business Park included. Send details of the unit and the work through our quote form for a quick quote.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you fire stop behind the services contractors?

Yes, where there is a specification for those walls and floors. New services after M&E works often breach existing seals and we close them with the specified product.

Can the sealant be colour-matched?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Will you just go over the old 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.

Quoting for work in Hockley

We price every job individually. The things that drive the figure:

  • Access and working height
  • Phasing around occupants
  • Removal of failed or old sealant
  • The site’s rules and procedures

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 we need to price the job

However big the job, the same details help:

  • Asbestos survey details if the building is older
  • The product your specification calls for
  • Where the site is, with the postcode
  • Photos of the joints, close up and from further back

For a fixed quote, give us a call on 01277 525 020 or email the details over, telling us the site location and the nature of the job. Our quote form is another easy route.
