Fire stopping across Royal Docks

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Fire stopping for commercial buildings in Royal Docks

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. If the detail calls for something other than sealant, we say so rather than force sealant into it. We work on service gaps in risers, joints between fire-resisting walls and floors and small duct penetrations where the tested detail allows, and the failures we’re asked to look at most are damaged fire seals in risers and voids and unsealed joints where partitions meet the slab. For commercial sealant work in Royal Docks, you deal with one contact from quote to sign-off, whether it’s one building or several.

In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. We install what the designer or fire engineer has specified, and if you need records of the work, tell us and we will confirm with the quote.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Fire stopping around Royal Docks: what changes locally

Royal Docks has plenty of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. There are seven care or nursing homes within about 2 miles of Royal Docks. Where new services have gone through compartment walls in a care setting, the gaps need the specified product.

In a retail centre such as Beckton Retail Park, which lies north-east of Royal Docks, any fire-resisting wall between units that is crossed by new services needs sealing to the tested detail. Campus buildings at universities such as University of East London, 0.9 miles to the east of Royal Docks, see constant changes to data and services, and fire-rated sealant goes in around new penetrations where it is specified. Wherever services are added at a hospital such as Newham University Hospital, 1.1 miles north of Royal Docks, the compartment line has to be made good with the specified product.

Royal Docks is about 1 mile south-east of Canning Town, in Greater London. Across the E16 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Royal Docks is one of 764 places we cover in Greater London. There’s a separate page for London, about 6 miles away.

Business premises anywhere in E16 and E6 are within our area for service penetrations. Among the streets we cover are Drew Road, Leyes Road and Camel Road, and sites on any of them can send details for a fixed quote. You’ll find Royal Docks on or near the A1020, so getting applicators and materials to site is simple. If your building is just outside Royal Docks, we cover Custom House (1 mile west), Silvertown (1 mile south-west), North Woolwich (1 mile south-east), West Silvertown (1 mile west) and Canning Town (1 mile north-west). Nearby towns on our patch include London (6 miles west), City of Westminster (8 miles west), Marylebone (8 miles west), Kensington (11 miles west), St Pancras (7 miles west) and Shoreditch (5 miles west).

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself typically takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We read the specification, drawings or penetration schedule you send and ask about anything unclear.
  2. On site, each opening is checked against the tested detail it is meant to follow.
  3. Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
  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.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification
  • Point out parking and an unloading spot

Royal Docks: questions and answers

Can you take on a job at a hospital such as Newham University Hospital?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you work around term dates at a campus such as University of East London?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Will fire-rated sealant work on every penetration?

No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we will tell you when that applies.

Do you cover Royal Docks?

Yes. Sites across Royal Docks are covered, and the same phone number covers every area.

What if there’s asbestos in the old mastic?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Do you seal openings left by new services?

Yes. Share the penetration schedule and product details. Work can run area by area behind the M&E trades keeping pace with the programme.

How do you choose the sealant?

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.

Why act early in Royal Docks

The longer openings stay, the more there tend to be: every new cable or pipe adds another. A schedule that is dealt with regularly stays manageable. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.

A quote for service penetrations depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

Why us?

  • CHAS accredited
  • A Constructionline member, so easy to vet
  • One number for every site we cover
  • 12-month guarantee on workmanship

Take a look at our cost guide or our accreditations.

Looking after the joints

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • File the specified details where the next contractor can find them
  • Settle who seals which penetrations at the start of a project
  • Make fire stopping part of every scope that crosses a fire-resisting wall
  • Check risers and ceiling voids after each round of works

After the work, brief anyone else working in the area that the openings are now sealed. If a seal has to be opened for a new service, it should be reinstated to the same detail using the same product.

Write fire stopping into the scope of any work crossing a compartment wall or floor. Then the seal goes in while the area is open, not months later.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Different surfaces, different methods

Drylining partitions

Holes in board are often cut larger than needed. An oversized hole may be outside the sealant’s range, and the detail may call for board patching or another product.

Risers and ceiling voids

Openings above suspended ceilings are easy to miss. We follow your schedule area by area.

How the quote is worked out

We price every job individually. The main factors are:

  • Working within restricted access windows
  • How much existing material needs removing
  • The total length or number of joints
  • Which sealant the job calls for

What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Details that help us quote

However big the job, these details speed things up:

  • Whether an asbestos survey exists
  • Anything awkward about access or site hours
  • Rough lengths or quantities, or drawings if you have them
  • The type of building and who uses it

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to phone 01277 525 020 or use the quote form.
