Commercial clients in Thorpe-le-Soken

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 Thorpe-le-Soken can sit alongside others in a wider programme across Essex.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

Fire stopping for commercial buildings in Thorpe-le-Soken

We should be clear about what we do and don’t do. The designer, fire engineer or building control decides which fire stopping is required; sign-off sits with them too. We fit the specified fire-rated sealant following that specification and the maker’s installation guidance on buildings around Thorpe-le-Soken. The enquiries we see most involve fire stopping installed outside its tested range and openings left by services added after handover, across pipe penetrations, cable penetrations and service gaps in risers. A single leaking joint is often how a building in Thorpe-le-Soken first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Thorpe-le-Soken, many commercial buildings are conversions or extensions of older ones, so it’s worth confirming the wall or floor type before choosing the seal. The right product depends on the wall or floor and the services passing through, and we will tell you if the detail calls for something other than sealant.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we’re clear about what is covered before work starts.

General trades versus a specialist

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.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Thorpe-le-Soken: questions and answers

What does the BS 476 change mean for fire-rated sealant in Thorpe-le-Soken?

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. Our part doesn’t change: the specified product, to its tested detail.

Do you cover business parks and estates near Thorpe-le-Soken, such as Rice Bridge Industrial Estate?

Yes. We cover Thorpe-le-Soken and the area around it, including industrial estates, business parks and retail parks such as Rice Bridge Industrial Estate. A few photographs and the unit address let us price the work.

Is the work guaranteed?

Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

What will the job cost?

It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.

Are you CHAS accredited?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

What the job involves on each surface

Masonry and concrete

Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point against the detail’s limits.

Linear joints

Head-of-wall gaps, slab edges and wall junctions are linear joints. Their tested detail, under BS EN 1366-4, sets the width, depth, backing and movement allowed and the installation has to fit inside those limits.

Keeping the joints sound

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

  • Foam or ordinary sealant is never a fire-seal repair
  • Leave fire sealant to cure fully before covering it
  • Treat an open penetration as a priority repair
  • File the specified details where the next contractor can find them

Allow the manufacturer’s stated cure time before boxing in or decorating. Some fire-rated sealants accept paint and some don’t.

Regular walk-rounds of service areas are worth the time. A cracked or disturbed seal found early is a small job.

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If neighbouring businesses or buildings around Thorpe-le-Soken need work too, visits can be combined. Tell us your site hours and we will plan around 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. 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. If an opening needs something other than sealant, we tell you instead of improvising.

What we need from you

  • Let us know about inductions and permits
  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed

Advice

Why deal with it now?

Sealing behind the M&E trades area by area beats a sweep at the end. Openings are visible, access is open and nothing has to be taken down. For buildings in places like Thorpe-le-Soken, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What you get with us

  • A fixed quote before work starts
  • Workmanship guaranteed for 12 months
  • Joints cleaned back to sound surfaces
  • Sealing commercial buildings since 2005

Fire stopping in Thorpe-le-Soken: the local picture

Thorpe-le-Soken lies roughly 60 miles out 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. 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. Our part stays the same: the specified product, installed to its tested detail.

On estates like Rice Bridge Industrial Estate, 0.9 miles to the south of Thorpe-le-Soken, the wall between office and warehouse is often fire-resisting, and cables through it need the specified seal. Holiday works at schools like Rolph CofE Primary School often leave service openings to seal before pupils return. In a building such as Parish Church of St Michael, any service penetration through a fire-resisting wall should be sealed to the specified detail.
