Commercial clients in Nevendon

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Fire stopping in Nevendon, done properly

Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you’re dealing with head-of-wall gaps with no fire seal and seals disturbed by maintenance and left open, we can put it right. Whoever orders the work in Nevendon, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Nevendon, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Include service cupboards in routine inspections
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Report damaged or disturbed seals as soon as they’re spotted
  • Record which product was used where

Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail using the same product.

A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate.

Should maintenance staff do it?

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

From enquiry to 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 the sealant is tooled off neatly. Smaller jobs around Nevendon can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. The specification and schedule come first, so we know which details apply.
  2. Access, permits and the order of areas are agreed with the site team.
  3. We compare every service penetration with its tested detail before sealing.
  4. Foam, ordinary sealant and debris come out first.
  5. The specified backing and sealant go in to depth and are finished neatly.
  6. We tell you about openings that need a different product.

Advice

Common problems we fix in Nevendon

Mixing products or improvising a detail breaks the link with the test evidence. An oversized gap, too shallow a bead, missing backing or two makers’ products combined are what we find most often.

Look out for the following:

  • Fire-rated sealant that has cracked or shrunk back
  • Unsealed penetrations discovered above suspended ceilings
  • Open linear gaps along the top of fire-resisting walls
  • Fire-stopping items raised at inspection or handover

Where a unit on an estate such as Burnt Mills Industrial Estate, which lies south-west of Nevendon, has fire-resisting walls between offices and warehouse, any new service through them should be sealed to the tested detail.

What to look for in a quote

  • Their pre-qualification and accreditations
  • Whether their applicators hold CSCS cards
  • What level of public liability insurance do they hold?
  • How the joint faces will be prepared and primed

Choosing a commercial sealant contractor

Service penetrations in Nevendon buildings

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 28 miles from Nevendon. Tenant changes on commuter-belt business parks mean regular fit-outs, and new services through compartment walls.

Theatres, wards and plant rooms at sites like Basildon University Hospital (to the south-west of Nevendon) all have compartment walls crossed by services. For a building such as Church of All Saints, new heating or data runs are the usual reason penetrations need sealing.

Nevendon is about 1 mile south of Wickford, in Essex. We send applicators to Nevendon for service penetrations. Our Essex coverage takes in 644 places. Our London page has more on work in that area (28 miles or so).

Anyone looking for fire stopping in SS12 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed.

Questions we are asked in Nevendon

Is Nevendon too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

What does the BS 476 change mean for fire-rated sealant in Nevendon?

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.

How soon can the area be used again?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Are you fully insured?

Yes. Our insurance certificate can be sent alongside the quote.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Large openings beyond what any sealant detail covers
  • Writing the fire-stopping specification
  • Signing off or certifying a building’s fire stopping

If you’re not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer.

What we seal

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