How we handle floor joint sealing in Surrey Canal

A working floor can rarely be closed for days on end, so the work is split into zones and treated one area at a time. Tell us your site hours and access windows and we’ll plan around them so the rest of the operation keeps going. We work on joints along racking aisles, loading bays and construction joints, and the failures we are asked to look at most are filler that has parted from one face and untidy open joints in a retail unit. Most enquiries from Surrey Canal start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around Surrey Canal, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.

Work we carry out in Greater London comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Questions we are asked in Surrey Canal

Is a hospital such as Guy's Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Do you work in London buildings with loading restrictions?

Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for

Are you CHAS accredited?

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

Is the floor joint work guaranteed?

Every job has our 12-month guarantee. It covers our workmanship, not later slab movement or damage from impacts.

How do we get a quote for floor joints?

Send details through our quote form or by email, with the traffic on each area. We then send a fixed quote that shows the products and zones.

When can forklifts run over new joint filler?

Cure times vary with the product and the conditions. You’ll get a reopening time for each area when we agree the phasing.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Common problems we fix in Surrey Canal

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.

Typical triggers for a call:

  • Brittle joint filler breaking up
  • Joint edges breaking up under truck wheels
  • Trucks and loads jolting over damaged joints
  • Failing joints at loading bays and dock doors

At places like Bermondsey Trading Estate, which lies north-west of Surrey Canal, joints are sealed a section at a time so operations carry on.

Questions to ask before you book

  • The terms of the workmanship guarantee
  • How they’ll work around occupants
  • How they handle RAMS and site documents
  • Will CSCS-carded applicators be on site?

How to choose a sealant contractor

Cost factors for floor joints

Before we quote, we look at:

  • Access and working height
  • Phasing around occupants
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

What to include in your enquiry

Good information means a firmer quote. When you get in touch, include:

  • Rough lengths or quantities, or drawings if you have them
  • Specification clauses that apply
  • The postcode of the building
  • Asbestos survey details if the building is older

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Joints that move: notes for Surrey Canal

In London, decks, bays and service yards normally have to keep running, which is why we work a few bays at a time. Surrey Canal 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.

At a retail site such as Surrey Quays Shopping Centre (0.7 miles north of Surrey Canal), trolleys, cages and cars run over floor and slab joints all day. On a site such as Orion Business Centre, less than half a mile south-east of Surrey Canal, the movement joints are in car park slabs, paving and building elevations.

Surrey Canal is about 1 mile north-west of New Cross, in Greater London. Looking for floor joint sealing in Surrey Canal? We can help, as we do across Greater London. Our Greater London coverage takes in 764 places.

Anyone looking for floor joint sealing in SE16, SE15 and SE14 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. For a building on Pump Lane, Bush Road and Water Lane or nearby, send details and we will quote for floor joints. Surrey Canal sits on or close to the A200 and A2208. Just outside Surrey Canal, we also work in South Bermondsey (1 mile west), Surrey Quays (1 mile north-east), Rotherhithe (1 mile north), Peckham (1 mile south-west) and Deptford (1 mile south-east). A short drive away, we cover City of Westminster (5 miles north-west), Marylebone (5 miles north-west), Kensington (7 miles west), St Pancras (4 miles north-west), Shoreditch (3 miles north-west) and Walthamstow (7 miles north).

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Level or flatness problems across the floor
  • Spalled arrises, which need an edge repair first
  • A failing floor coating, which is a flooring contractor’s job

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

Joints and surfaces we work on

  • Loading bays
  • Construction joints
  • Forklift and pallet-truck routes
  • Retail and showroom floors
  • Joints along racking aisles
  • Saw-cut induced joints

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. In Surrey Canal, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.

  1. We agree the traffic routes and phasing with your site team.
  2. Any joints with broken edges are flagged before work starts.
  3. Failed material and debris are removed and the joint cleaned.
  4. The chosen filler or sealant goes in flush with the slab.
  5. Each area is handed back when ready for traffic.

What we need from you

  • Tell us your opening times and when work is allowed
  • Make sure the joints can be reached
  • Flag any permit to work we will need

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.

Advice

What happens if it’s left?

Painting or coating straight over joints rarely lasts. Joints need their own treatment, whether or not the floor is coated. In Surrey Canal, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • CSCS-carded applicators
  • Fixed quotes based on photos, drawings or a visit
  • CHAS accredited contractor
  • Constructionline member for supplier checks

Looking after the joints

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

  • Remind operators to lift rather than drag
  • Record damaged joints with a photo and a location
  • Walk the main routes and inspect joint lines on a regular cycle
  • Put loading bays at the top of the list

Dragged forks and pallets gouge joints and edges alike. Steel tines will mark a good joint over time.

Treating joints while the arrises are sound keeps the work simple. Once they have broken away, edge repair comes first and that takes longer and closes areas for longer.
