Fire stopping in Broad Green: the local picture

There are a number of hotels within about 2 miles of Broad Green. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. Broad Green lies roughly 44 miles out from central London. Offices around the capital are refitted often, and the cabling that follows can breach fire-resisting walls.

Schools such as Honywood Community Science School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards. Office fit-outs on sites such as Threshelfords Business Park, 2.4 miles to the south of Broad Green, add cabling and pipework through fire-resisting walls, and fire-rated sealant goes in where the specification calls for it.

Broad Green is about 6 miles south-east of Halstead, in Essex. Anywhere in CO6, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Essex coverage takes in 644 places. Sites around London have their own page, roughly 44 miles from Broad Green.

Fire stopping in Broad Green, done properly

Sealant is the specified answer for plenty of openings, such as metal pipes, cables and some small ducts where the detail covers them. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. If you have fire-rated sealant that has cracked or shrunk back and unsealed joints where partitions meet the slab, we can help. Most enquiries from Broad Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Rural conversions around Broad Green can put new fire-resisting partitions inside older structures. A penetration seal only performs as tested if product, substrate, service, gap and depth all match the detail.

A 12-month guarantee applies to all our work in Essex. If an installation problem shows up, call the office on 01277 525 020 or email the details over and we’ll arrange a return visit.

Commercial clients in Broad Green

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

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

After the work

A few simple habits keep the new joints working:

  • Put resealing into every M&E and fit-out package
  • Check risers and ceiling voids after each round of works
  • Get seals inspected before ceilings and boxing close
  • Treat an open penetration as a priority repair

Keep the product data and installation details with the building’s fire safety information. It makes later repairs much easier to match.

Keep a register of where seals are and what they are made of. When a new service goes through, everyone knows which product and detail to match, which saves guesswork.

How a job runs

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a single visit for a short list of penetrations, or a phased programme for a whole building. Smaller jobs around Broad Green can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We ask for the product and detail your designer has specified.
  2. We sort the openings by the detail each one needs.
  3. Old or wrong materials are cut out.
  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.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Tell staff and tenants when we’ll be in
  • Arrange parking or a loading space

Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

Questions we are asked in Broad Green

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

Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes 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 seal penetrations in a hotel in Broad Green after a refit?

Yes. We install fire-rated and intumescent sealant where it is specified. We match the product to the wall or floor and the services, and say if something other than sealant is needed.

Can you quote from photographs?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Is the work guaranteed?

Yes. Workmanship is guaranteed for 12 months.

How soon can the area be used again?

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

What hours do you work?

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

What if there’s asbestos in the old mastic?

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

When to call us in Broad Green

Damage plays a part too. Maintenance work can knock a seal, cut it back for an extra cable or remove it with an old pipe and the opening isn’t always resealed.

Look out for the following:

  • Unsealed openings around new pipes and cables
  • Seals that don’t match their tested detail
  • Fire sealant pulled out of the opening
  • Unsealed joints where partitions meet the slab

Older community buildings such as Church of St James that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Before you book anyone

  • Can the work be phased to keep areas open?
  • Do they follow the manufacturer’s priming guidance?
  • How the existing material will be dealt with
  • How joint depth will be controlled

Our contractor checklist

Doing it in-house

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

What the job involves on each surface

Metal pipes

Sealant details often cover copper and steel pipework. Pipe diameter, annular gap, sealant depth and any pipe insulation all have to match the detail, so we check each one.

Cables and cable bundles

Data cabling added after handover is a regular cause of open service penetrations. We reseal around them to the specified detail, and any bundle too large for sealant alone is flagged.
