Fire stopping for commercial buildings in Newick

We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. We work on service gaps in risers, pipe penetrations and joints between fire-resisting walls and floors, and the usual reasons a site gets in touch are damaged fire seals in risers and voids and expanding foam used as fire stopping. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Newick is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.

A job near Newick is typically planned around one visit, with the specification and photographs sent in advance. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

When to call us in Newick

Fire stopping can get squeezed at the end of a programme, or done by whoever is on site. That is how unsuitable products and improvised details end up in compartment walls and later need putting right.

Look out for the following:

  • Fire stopping installed outside its tested range
  • Fire-stopping items raised at inspection or handover
  • Open linear gaps along the top of fire-resisting walls
  • Old intumescent sealant that has split away

For a school such as Newick Church of England Primary School, penetration sealing fits best at the end of the summer works.

Questions to ask before you book

  • Their public liability cover
  • How they handle RAMS and site documents
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?

Our contractor checklist

How the quote is worked out

Quotes vary with the job. It mainly depends on:

  • The site’s rules and procedures
  • Backing rod, priming and other preparation
  • The total length or number of joints
  • Access and working height

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a quote once you have the details.

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
  • The type of building and who uses it
  • When you need the work done
  • Photos of the joints, close up and from further back

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, speak to us on 01277 525 020 or email a schedule or drawings.

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Record which product was used where
  • Keep general-purpose fillers away from compartment walls
  • Settle who seals which penetrations at the start of a project
  • Get seals inspected before ceilings and boxing close

Don’t patch a fire-rated seal with anything outside its tested detail. A repair should use the original product, installed the same way.

The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. That way the opening is sealed while the trade and access are still there.

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, and any that don’t are flagged.

Linear joints

Joints at the top of partitions may need to move as the slab above deflects. The specified product and backing for that movement are what goes in, along the full length of the run.

Compartment walls and floors in Newick

Central London is about 37 miles from Newick. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls. Fire stopping of openings and penetrations in England falls under Approved Document B. Its BS 476 references are being withdrawn from 2 September 2029, with BS EN 13501-2 classification taking over, subject to transitional arrangements. Either way, we install the specified product to its tested detail.

At a university such as University of Sussex, which lies south-west of Newick, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work. Wherever services are added at a hospital such as Uckfield Community Hospital (4 miles east of Newick) the compartment line has to be made good with the specified product.

Newick is about 4 miles west of Uckfield, in East Sussex. We send applicators to Newick for service penetrations. Newick is one of 308 places in East Sussex on our list. We also cover Brighton, some 12 miles away.

Work on service penetrations is covered throughout BN8, whatever the building. If your site is on High Street, Church Road and Station Road or close by, we can quote for service penetrations. Sites close to Newick are covered too, including Founthill (1 mile south-east), North Chailey (1 mile west), Chailey (1 mile south-west), South Street (2 miles south-west) and Down Street (3 miles north-east). Further afield, our area takes in Seaford (14 miles south), Lewes (7 miles south), Hailsham (13 miles south-east), Crowborough (9 miles north-east), Uckfield (4 miles east) and Newhaven (12 miles south).

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Newick may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. We ask for the product and detail your designer has specified.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  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. Completed areas are checked with you, with the records agreed when we quoted.

Advice

Why deal with it now?

Leave a penetration open and smoke and fire can cross into the next compartment far earlier than intended. Putting it right is normally a modest job when the openings are accessible. Left until ceilings are closed or a tenant moves in, the same work costs more access and more disruption. Around Newick, it’s better to renew all the failing joints at once, rather than one at a time. Photos of every joint help us quote for the whole job.

No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

FAQs: Newick

What happens to BS 476 references for fire stopping in Newick?

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.

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

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you quote from photographs?

It depends on the job. Simple work can often be priced from photographs, and bigger or more complex jobs usually get a visit.

How long before the joints can be used?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

Do you take on small jobs?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Can you work while the building is occupied?

In the majority of cases, yes. We phase the work so most of the building stays in use.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
