Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Floor joint sealing for commercial buildings in St George in the East

Concrete floors in warehouses and factories are cut into bays by saw-cut joints and construction joints, and every one of those joints is an exposed edge under hard wheels. Our job is to put the right filler or sealant into them for the loads and the movement they see, so the arrises are supported and grit stays out. Site teams most often ask us about a gap opening alongside old joint filler and drivers complaining about joints on a route, across joints along racking aisles, forklift and pallet-truck routes and construction joints. One point of contact handles commercial sealant work in St George in the East from the first photos to the final walk-round, whether it’s one building or several.

Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What we are called out for in St George in the East

Left open, joints fill with grit, wrap and wood fragments. That debris is hard and levers at the edges as wheels pass, speeding up the damage.

Common reasons buildings call us in:

  • Joint fill separating from the concrete
  • Failing joints at loading bays and dock doors
  • Untidy open joints in a retail unit
  • Sealant pulled out along a truck route

A healthcare site such as Royal London Hospital (0.7 miles north of St George in the East) depends on car parks, ramps and service yards whose joints take traffic all day.

Before you book anyone

  • What the guarantee covers, and for how long
  • Will CSCS-carded applicators be on site?
  • How the joint faces will be prepared and primed
  • How they handle RAMS and site documents

Questions to ask before you appoint anyone

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. 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. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Preparing the site

  • Have the specification and drawings to hand
  • Make sure the joints can be reached
  • Flag any permit to work we’ll need

What sets the cost

What shapes the price:

  • Working within restricted access windows
  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements
  • Joint width, depth and condition

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

What we need to price the job

It doesn’t need to be a full survey. These details are enough to start:

  • Anything awkward about access or site hours
  • The asbestos register, for older buildings
  • What the building is and how it’s used
  • The product your specification calls for

Need a figure for a tender or a budget? We will quote against your scope and drawings that you can work with. For a chat about it beforehand, call the office on 01277 525 020 or send photos by email.

Leave it or put it right?

Tape, or whatever sealant is in the stores cupboard, may look like a fix for a while. Neither is made to carry wheels and traffic soon pulls it out. A product chosen for the traffic and movement does the job once. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

General trades versus a specialist

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Surface by surface

Semi-rigid joint fillers

On industrial routes, a semi-rigid filler is often the right choice. We place them to depth and trim them level with the slab.

Flexible floor sealants

A flexible sealant suits perimeter and movement joints away from the heaviest traffic. Closed-cell backing rod goes in first, keeping the bead shallow and gripping only the two faces.

St George in the East: questions and answers

Can you take on a job at a hospital such as Royal London Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Can you work at a site such as Princes Court Business Centre, by St George in the East?

Yes, sites like Princes Court Business Centre are within our area, along with the rest of St George in the East. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Should floor joints be filled or sealed?

It depends on the traffic and the movement. Forklift routes generally call for a semi-rigid filler that holds the arrises, while joints that move more take a flexible sealant.

Does weather matter for sealant work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

What happens if old sealant might contain asbestos?

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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

Joints that move: notes for St George in the East

In London, decks, bays and service yards typically have to keep running, so we seal in sections and hand areas back as each cures. St George in the East has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Another example is City Business Centre, 0.7 miles south-east of St George in the East, where floors and yards would be done in stages around the occupiers.
