About our fire stopping in Great Wakering

No fire sealant works on its own: its test evidence covers one product in one kind of wall or floor, with set services, gaps, depths and backing. Before we seal anything, we check the opening against the detail it is meant to follow, and we say so if it doesn’t fit. We work on small duct penetrations where the tested detail allows, joints between fire-resisting walls and floors and cable penetrations, and the failures we are asked to look at most are penetration schedules that need working through and fire seals cut back for extra cables and never reinstated. Facilities teams, main contractors and managing agents in Great Wakering tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around Great Wakering, penetration and linear seals tend to be one-building jobs. With the specification and photos of the gaps, we can give a fixed quote and bring the right products.

Our workmanship is guaranteed for 12 months, in Great Wakering as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Quoting for work in Great Wakering

Before we quote, we look at:

  • Removal of failed or old sealant
  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • Backing rod, priming and other preparation

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

What we need to price the job

A good diagnosis starts with the right details. Let us know:

  • The asbestos register, for older buildings
  • Clear photos of the problem areas
  • How the joints are reached, and at what height
  • Any specification or named product

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or send details through our quote form.

Commercial clients in Great Wakering

Building owners and managing agents use us on everything from one building to a spread of sites around Great Wakering. One quote can cover more than one site, which keeps the paperwork simple.

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

Our process

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Several jobs near Great Wakering can be grouped on one trip. Mention the building’s opening times and we will work within them.

  1. First we go through the drawings, schedule or specification for the seals.
  2. Every penetration is compared with its detail: wall or floor type, service, gap size and depth.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  4. We fit the backing the detail asks for, to the stated depth.
  5. We apply the specified sealant to the depth and around the services as the detail shows.
  6. If an opening needs something other than sealant, we tell you instead of improvising.

Preparing the site

  • Let building users know which areas are affected
  • Arrange parking or a loading space
  • Tell us which areas need to stay in use

Ask for a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Maintenance after handover

To get the most from the new sealant:

  • Have penetrations checked while they can still be seen
  • Treat an open penetration as a priority repair
  • Keep general-purpose fillers away from compartment walls
  • Ask the designer to confirm details early on refits

Give the sealant its full cure time before ceilings, boxing or decoration go over it. Not every fire-rated product can be painted, so check the product data first.

Make reporting new openings part of every permit to work in service areas. It costs little and catches breaches early.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Fire stopping around Great Wakering: how the place shapes the job

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. What we install is set by the specification, and it goes in to the tested detail. Great Wakering lies roughly 39 miles out from central London. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.

For a unit at a site such as Star Lane Industrial Estate, 0.7 miles west of Great Wakering, new power or data runs between office and warehouse can breach a compartment wall. For a school such as Great Wakering Primary Academy, penetration sealing fits best at the end of the summer works. Campus buildings at universities such as University of Essex, 4.1 miles to the west of Great Wakering, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified.

Great Wakering is about 1 mile north-east of Shoeburyness, in Essex. Any commercial site in Great Wakering is covered, for single jobs and planned programmes alike. 644 places across Essex fall within our area, Great Wakering among them. London is covered too, around 39 miles from Great Wakering.

Surface by surface

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We work through the areas on your schedule methodically.

Metal pipes

Copper and steel pipes are a common service penetration for fire-rated sealant. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

Your questions answered

Could you schedule work at a campus like University of Essex for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

How does the move away from BS 476 affect penetration seals in Great Wakering?

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

How do you deal with asbestos in old sealant?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

How long does a typical visit take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

How much does the work cost?

Each job is quoted on its own details. To get one, phone 01277 525 020 or email the details over with a description of the work.

Do you seal on top of existing sealant?

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