About our floor joint sealing in Hackney Wick

We have been sealing commercial joints since 2005. Applicators carry CSCS cards and work to your site rules, and we are CHAS accredited and a Constructionline member holding public liability insurance. Completed joints come with a 12-month guarantee on our workmanship. We work on retail and showroom floors, joints along racking aisles and saw-cut induced joints, and the failures we are asked to look at most are scruffy, dirty joint lines on a shop or showroom floor and drivers complaining about joints on a route. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Hackney Wick, preparation and product choice get the time they need.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. Planning a job in Hackney Wick means thinking about access, loading times and the ULEZ as well as the joints.

A 12-month guarantee applies to all our work in Greater London. Should something we installed fail, call 01277 525 020 or email the details over and we’ll come back to it.

Traffic, movement and joints around Hackney Wick

Few London car parks or loading bays can be taken out of use for more than a short spell, which is why we work a few bays at a time. The 3 miles around Hackney Wick take in at least three named trading estates, business parks or retail parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.

Phasing is what makes joint work possible on busy sites such as Victoria Park Industrial Centre (less than half a mile west of Hackney Wick): one bay, aisle or car park row at a time. For estates staff at a university like University of Staffordshire London Campus, under half a mile north of Hackney Wick, building and paving joints are part of the planned maintenance list. Hospital campuses such as Homerton University Hospital (to the north-west of Hackney Wick) grow in stages, leaving movement joints wherever new blocks meet old.

Hackney Wick is about 1 mile west of Stratford, in Greater London. Hackney Wick sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Our Greater London coverage takes in 764 places, from busy centres to rural villages.

If you need floor joint sealing in E3, E9 and E20, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Buildings on Wick Lane, Dace Road and Wyke Road are within our area. Just outside Hackney Wick, we also work in Fish Island (1 mile south), Donnybrook Quarter (1 mile south-west), Old Ford (1 mile south), Temple Mills (1 mile north-east) and East Village (1 mile north-east). Bigger towns within reach include London (4 miles south-west), City of Westminster (6 miles west), Marylebone (6 miles west), Kensington (8 miles west), St Pancras (4 miles west) and Shoreditch (3 miles south-west).

What’s near Hackney Wick

We work on buildings around Mulberry UTC, Mabley Green and Mulberry UTC and the streets around them. Hackney Wick has its own railway station: Hackney Wick station. Nearby you will also find Tower of London (3.3 miles south-west) and V&A East (less than half a mile east). Not far away are Tower Hill and Old Ford Island.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Diagnose, treat, sign off

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. You get a fixed quote with the product and the phasing set out.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. We fill each joint to depth and finish it flush so wheels roll straight across.
  6. We tell you when each zone can carry trucks again and move on to the next.

Before we start on site

  • Move anything stored against the joints
  • Have the specification and drawings to hand
  • Let building users know which areas are affected

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Hackney Wick: questions and answers

Do you take on work at healthcare sites like Homerton University Hospital?

Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you take on work at estates like Hamlet Industrial Estate, close to Hackney Wick?

Yes. Our area takes in Hackney Wick and its surroundings, with estates and business parks such as Hamlet Industrial Estate included. Photos and a short description are enough for a first look.

How long does a job like this take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

What happens if the joint edges are damaged?

We check the edges as part of the survey. Where they have broken away, we’ll tell you before quoting the filling, so nothing is filled that won’t hold.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Should floor joints be filled or sealed?

There isn’t one answer for a whole floor. Hard wheels need edge support, which points to a semi-rigid filler, and movement joints or perimeters need something flexible. You will see the choice for each area in the quote.

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Allow for topping up joints as a new slab settles
  • Stop forks and pallets being dragged across joints
  • Sweep debris out of open joints until they can be filled
  • Respect the cure time before traffic returns

Dragged forks and pallets gouge joints and edges alike. Even a well-filled joint can be damaged by steel scraping along it.

Grit in an open joint does damage every time a wheel crosses it. Filling it ends that cycle while it is still a straightforward job.

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

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

What sets the cost

These are the things that shape the price:

  • How accessible the joints are
  • How much there is to seal
  • Induction, permit and paperwork requirements
  • The size and state of each joint

Pricing floor joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What we need to price the job

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • What the building is and how it’s used
  • When you need the work done
  • Clear photographs of the problem areas
  • The site address and postcode

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

When something else is needed

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Damaged or worn floor coatings and screeds
  • Spalled arrises, which need an edge repair first
  • Slab panels that rock or move under load

If in doubt, ring 01277 525 020 or use the quote form and we will say what we think before you book.
