Fire stopping near Tinkers Cross

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

Building owners, agents and FMs in Tinkers Cross

We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Fire stopping in Tinkers Cross

The test standards are BS EN 1366-3 for penetration seals and BS EN 1366-4 for linear joints, with results classified under BS EN 13501-2. That classification, such as EI 60 or EI 120, belongs to the product in its tested arrangement. So our job is to reproduce that arrangement faithfully. Site teams most often ask us about builders’ foam or ordinary silicone in compartment walls and seals that don’t match their tested detail, across pipe penetrations, service gaps in risers and small duct penetrations where the tested detail allows. A specialist sealant contractor works differently from a general builder: on jobs in Tinkers Cross, preparation and product choice get the time they need.

Barn and farm-building conversions near places like Tinkers Cross 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

On site: what to expect

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Tinkers Cross, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
  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.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Point out parking and an unloading spot
  • Tell staff and tenants when we will be in

Related advice

Why deal with it now?

Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed, so earlier action pays back. Halls, stores and units around places like Tinkers Cross may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Why appoint us

  • Health and safety: CHAS accredited
  • Public liability insurance in place
  • Joints cleaned back to sound surfaces
  • 12-month guarantee on workmanship

Read our cost guide and our accreditations.

What we are called out for in Tinkers Cross

Plenty of openings were simply never closed because they sat out of sight above a ceiling or inside a riser. Inspections, refurbishments and ceiling access normally bring them to light.

What tends to prompt an enquiry:

  • Seals disturbed by maintenance and left open
  • Unsealed joints where partitions meet the slab
  • Unsealed openings around new pipes and cables
  • Openings found when ceilings come down for a refit

Where a unit on an estate such as Arch Farm Industrial Estate, under half a mile to the south-east of Tinkers Cross, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

What your quote should include

  • Do they follow the manufacturer’s priming guidance?
  • Which product they’ll use, and why it suits the joint
  • How they handle RAMS and site documents
  • Can the work be phased to keep areas open?

How to choose a sealant contractor

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • The site’s rules and procedures
  • Specialist products, such as fire-rated or hygienic sealants
  • Phasing around occupants
  • Location, for remote and island sites

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Details that help us quote

A few photographs plus some basic facts will normally do. Please tell us:

  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode
  • How the joints are reached, and at what height
  • Photos of the joints, close up and from further back

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, ring 01277 525 020 or email a schedule or drawings.

Tinkers Cross: questions and answers

How does the move away from BS 476 affect penetration seals in Tinkers Cross?

References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.

Is Tinkers Cross off your patch?

No. Places such as Tinkers Cross are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

What hours do you work?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

What do you charge?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a quote and we’ll price it properly.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Our part stays the same: the specified product, installed to its tested detail.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Approving the work on behalf of building control
  • Fire doors, dampers or other fire safety equipment
  • Openings that need collars, wraps, batts or boards rather than sealant

If you are not sure, just phone 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Linear gaps at wall heads
  • Small duct penetrations where the tested detail allows
