Fire stopping in Battersea, done properly

Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. We work to the product’s tested detail for every seal. We work on small duct penetrations where the tested detail allows, pipe penetrations and service gaps in risers, and the failures we’re asked to look at most are fire stopping installed outside its tested range and fire seals cut back for extra cables and never reinstated. Searching for sealant specialists in Battersea? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

London has many occupied offices, blocks and mixed-use buildings where services are added and rerouted all the time. Where the specification names fire-rated sealant, it goes in exactly as the manufacturer’s test evidence shows for that wall or floor.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.

  1. First we confirm the product and tested details named in the specification.
  2. Openings are measured and grouped by detail.
  3. Improvised fillers and failed sealant are removed.
  4. Mineral wool or other backing is fitted where required.
  5. Fire-rated or intumescent sealant goes in around the services and is tooled off.
  6. Completed areas are checked with you, with the records agreed when we quoted.

Before we start on site

  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance

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, give us a call on 01277 525 020 or send details through our quote form.

Questions about Battersea

Can you seal around new services in a hotel near Battersea?

Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.

Will you take on work at estates like Parkfield Industrial Estate, close to Battersea?

Yes, sites like Parkfield Industrial Estate are within our area, along with the rest of Battersea. To start, just call 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

What will the job cost?

There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Where services cross fire walls in Battersea

Battersea has a good number of hotels close by, all within 2 miles. A hotel refit often runs new services through compartment walls between bedrooms and corridors, and each opening needs the specified seal. The 2 miles around Battersea include three care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal.

Shop fits in centres such as Brompton Cross District Shopping Centre., 2.1 miles north of Battersea, can bring new services through fire-resisting walls between units, which then need the specified seal. At a university such as Royal College of Art, which lies north of Battersea, labs, lecture blocks and residences are re-serviced often, so penetration seals are best checked after M&E work.

Battersea is about 3 miles south-east of Kensington, in Greater London. We cover commercial sites throughout Battersea. Battersea is one of 764 places in Greater London on our list for service penetrations.

Anyone looking for fire stopping in SW11, SW18 and SW4 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. For a building on York Road, Este Road and Home Road or nearby, we can quote for service penetrations. Battersea sits on or close to the A3207, which helps when planning parking and deliveries for the job. Sites close to Battersea are covered too, including Clapham Junction (1 mile north-west), Sands End (1 mile north-west), Chelsea Harbour (1 mile north-west), Wandsworth (1 mile south-west) and Clapham (1 mile east). Further afield, our area takes in London (4 miles north-east), City of Westminster (4 miles north), Marylebone (4 miles north), Kensington (3 miles north-west), St Pancras (5 miles north-east) and Shoreditch (6 miles north-east).

Around Battersea, our work takes us to commercial buildings near The Falcon pub, Emanuel School and Imperial Park and the streets around them.

Green spaces nearby include Henman Hill and Battersea Park Lake.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Surface by surface

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.

Masonry and concrete

Block walls and concrete floors are common substrates for penetration seals. Dust and debris are cleared from the opening, so the sealant and any backing sit properly.

Aftercare for building managers

After handover, a little attention goes a long way:

  • Report damaged or disturbed seals as soon as they’re spotted
  • Look above ceilings when tiles are lifted for other jobs
  • Don’t let anyone top up a fire seal with the wrong product
  • Record which product was used where

After every round of M&E works, check that the openings created have been sealed. A short check at the end of each job saves a long hunt later.

Looking at service areas on a regular cycle pays off. A cracked or disturbed seal found early is a small job; found late, it can be one of many.

Cost factors for service penetrations

Quotes vary with the job. It mainly depends on:

  • Which sealant the job calls for
  • Phasing around occupants
  • Backing rod, priming and other preparation
  • Induction, permit and paperwork requirements

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Before you send an enquiry

Good information means a firmer quote. Helpful details to send:

  • Drawings or a marked-up plan, if available
  • The site address and postcode
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or email drawings and photos to discuss it first.

When to call us in Battersea

Openings in fire-resisting walls typically appear when services are added or changed. A new cable pulled by an electrician, a pipe rerouted by a plumber or a data run drilled through a riser can leave the hole behind. Across several fit-outs, the openings add up.

Common reasons buildings call us in:

  • Seals that don’t match their tested detail
  • Damaged fire seals in risers and voids
  • Penetration schedules that need working through
  • Fire sealant pulled out of the opening

At a college such as South Thames College Wandsworth Campus, which lies south-west of Battersea, checking penetration seals after summer M&E works is good practice.
