Canary Wharf: questions and answers

Do you cover business parks and estates near Canary Wharf, such as Poplar Business Park?

Yes, sites like Poplar Business Park are within our area, along with the rest of Canary Wharf. Send details of the unit and the work through our quote form for a quick quote.

Will our hotel in Canary Wharf need to close for the work?

Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.

Will the building have to shut during the work?

Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.

Can you handle sealant work across several sites?

Yes, across South East England, Greater London and all of Scotland. One contact and one process for every building makes a portfolio easier to manage.

Is it OK to apply fresh sealant over existing beads?

Removal of the failed sealant is always part of the job. Laying new silicone on old gives it nothing to grip.

Could the old sealant in an older building contain asbestos?

On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Commercial sealant contractors in Canary Wharf

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed. If a material is suspected, work stops until it’s tested. Most enquiries involve external beads that have gone brittle and cracked and water staining near frames, panels or ceilings, across window and door perimeters, movement joints in walls and floors and external facade joints. Facilities teams, main contractors and managing agents in Canary Wharf tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Quotes for commercial sealant in Canary Wharf can come from photographs and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.

Around Canary Wharf, as across the capital, commercial buildings range from converted period premises to recent office and mixed-use blocks, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Maintenance after handover

Problems stay small when the joints are checked regularly. In particular:

  • Keep a record of which joints were resealed and when
  • Put external and wet-area joints on a regular inspection round
  • Respect the cure time before reopening an area
  • Deal with small splits before they become leaks

Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records.

A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

What the job involves on each surface

Fire-rated seals where specified

Fire-rated sealant is only one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services and gaps.

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.

Commercial sealant contractors in Canary Wharf: the local picture

Four care or nursing homes sit less than 2 miles from Canary Wharf. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms. Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. Our planning starts from those rules rather than working round them later.

In hotels such as London Marriott Hotel Canary Wharf, which lies north-west of Canary Wharf, refurbishments usually mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. In a retail centre such as Surrey Quays Shopping Centre, which lies south-west of Canary Wharf, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish. A business with units at Poplar Business Park and Thomas Road Industrial Estate needn’t use two contractors for its sealant.

Canary Wharf is about 2 miles north-west of Greenwich, in Greater London. Anywhere in E14, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Canary Wharf is one of 764 places we cover in Greater London.

Anyone looking for commercial sealant contractors in E14, SE16 and E22 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. For a building on Castor Lane, Cassilis Road and Dockyard Lane or nearby, send details and we’ll quote for sealant joints. You’ll find Canary Wharf on or near the A1261. Close to Canary Wharf, our area also takes in London Docklands (1 mile east), Poplar (1 mile north-east), Heron Quays (1 mile south-west), Coldharbour (1 mile east) and Blackwall (1 mile east). Further afield, our area takes in London (3 miles west), City of Westminster (6 miles west), Marylebone (6 miles west), Kensington (8 miles west), St Pancras (4 miles west) and Shoreditch (3 miles north-west).

Cost factors for sealant joints

Before we quote, we look at:

  • Whether the work must be split into stages
  • Specialist products, such as fire-rated or hygienic sealants
  • Quantities, in metres or numbers
  • Joint width, depth and condition

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What to include in your enquiry

A few photographs plus some basic facts will normally do. It helps to include:

  • Approximate linear metres or a joint schedule
  • Asbestos survey details if the building is older
  • Specification clauses that apply
  • A wide shot and a close-up of the area

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, speak to us on 01277 525 020 or email drawings and photos.

When to bring in a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Our process

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. All of Greater London is in the ULEZ, and kerbside space in Canary Wharf can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. You send photos, drawings or a list of the joints and areas involved, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Point out any areas we must not close
  • Warn occupants and staff about the work
  • Share the asbestos register for older buildings

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Honest limits

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Roof leaks that only look like a joint problem
  • Misted, cracked or failed glazing units (a glazier’s job)

Not sure which it is? You can give us a call on 01277 525 020 or email the details over and we’ll tell you honestly.
