Fire stopping in Navestock Side, done properly

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Other openings need collars, wraps, batts, pillows or boards. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on cable penetrations, joints between fire-resisting walls and floors and service gaps in risers, and what we’re called in for most is openings left by services added after handover and open linear gaps along the top of fire-resisting walls. Whoever orders the work in Navestock Side, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Smaller places such as Navestock Side still have buildings with fire-resisting walls and floors: schools, halls, care homes and commercial conversions. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

FAQs: Navestock Side

Can you work around term dates at a campus such as Havering Technical College?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you work on a hospital site such as Brentwood Community Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

What does an EI 60 rating mean?

BS EN 1366-3 covers penetration seals and BS EN 1366-4 covers linear joints. Classification follows BS EN 13501-2, where E is integrity, I is insulation and the number is minutes, as in EI 60. That rating only holds when the product is installed to its tested detail.

What do you charge?

Each job is quoted on its own details. For yours, speak to us on 01277 525 020 or email a schedule or drawings.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Work for main contractors and building owners

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Navestock Side can sit alongside others in a wider programme across Essex.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

From enquiry to sign-off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a building around Navestock Side, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. Old or wrong materials are cut out.
  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. We walk the completed areas with you and confirm the records agreed at quote stage.

Before we start on site

  • Make sure the joints can be reached
  • Have the specification and drawings to hand
  • Tell us what induction or permit system the site runs

Advice

Where services cross fire walls in Navestock Side

For England, the fire stopping of penetrations is dealt with in 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. What we install is set by the specification, and it goes in to the tested detail. Central London is about 18 miles from Navestock Side. 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 unit at a site such as Hallsford Bridge Industrial Estate (2.9 miles north of Navestock Side), new power or data runs between office and warehouse can breach a compartment wall. Wherever services are added at a hospital such as Brentwood Community Hospital (to the south-east of Navestock Side) the compartment line has to be made good with the specified product. Colleges such as Havering Technical College (2.9 miles south-west of Navestock Side) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Navestock Side is about 3 miles north-west of Brentwood, in Essex. Anywhere in CM14, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Essex coverage takes in 644 places. Our London page has more on work in that area, about 18 miles away.

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

  • Designing or specifying fire stopping, which sits with the designer or fire engineer
  • Approving the work on behalf of building control
  • Gaps in walls that were never built as compartment walls

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

What we seal

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

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Quoting for work in Navestock Side

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Which sealant the job calls for
  • Phasing around occupants
  • Distance, for remote addresses
  • Removal of failed or old sealant

Pricing service penetrations depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Access details, including height
  • The asbestos register, for older buildings
  • Any specification or named product
  • The site address and postcode

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email us.

Why act early in Navestock Side

An improvised seal can look finished while offering no tested performance. The fix is to remove it and reinstall to the detail, so it makes sense to get it right first time. Around Navestock Side, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

Why appoint us

  • Public liability insurance in place
  • 12-month guarantee on workmanship
  • Specification-led, product-correct work
  • Old sealant cut out, never sealed over
