Commercial clients in Plumstead

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Plumstead can sit alongside others in a wider programme.

About our floor joint sealing in Plumstead

We diagnose the floor first rather than guessing at a product: how wide the joints are, signs of ongoing movement, the wheel types crossing them and the state of the arrises. From that we choose between a semi-rigid filler and a more flexible sealant and the answer can differ from one zone to the next. If you have broken arrises where pallet trucks cross and drivers complaining about joints on a route, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Plumstead from the first photographs to the final walk-round, whether it’s one building or several.

London’s floor joints are concentrated in warehouses and trade units, car parks, podiums and decks. In Plumstead, as everywhere in London, access, loading and the ULEZ all come into the plan.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Aftercare for building managers

To get the most from the new sealant:

  • Ask drivers not to drag forks or pallets
  • Mention any aggressive cleaning regime at quote stage
  • Walk the main routes and inspect joint lines on a regular cycle
  • Plan for a top-up on newer floors

Normal floor cleaning is fine once the product has cured. Tell us about aggressive cleaning products or hot washing at quote stage so the product suits them.

Joint damage starts slowly and then speeds up. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.

What we are called out for in Plumstead

An ageing filler or sealant can go brittle and split especially under daily scrubbing and traffic. At that point it neither holds the edges nor keeps debris out.

What tends to prompt an enquiry:

  • Broken arrises where pallet trucks cross
  • A gap opening alongside old joint filler
  • Grimy joint lines spoiling a showroom floor
  • Flexible sealant torn out by wheels

Parks like Gateway Business Centre (under half a mile north of Plumstead) combine paved areas, car parks and building elevations, each with joints that move.

Our contractor checklist

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.

  1. First, the zones and order of work are agreed with you.
  2. Any joints with broken edges are flagged before work starts.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Before we start on site

  • Tell us which areas need to stay in use
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Damaged or worn floor coatings and screeds
  • Unstable slabs moving under traffic
  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)

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

What we seal

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

Traffic, movement and joints around Plumstead

Less than 3 miles from Plumstead there are at least three named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. Few London car parks or loading bays can be taken out of use for more than a short spell, so the work is broken into short sections agreed with the building manager.

Retail centres such as Gallions Reach Shopping Park, 1.6 miles to the north of Plumstead, have floors, service yards and car parks with joints under constant traffic. Phasing is what makes joint work possible on busy sites such as Woolwich Dockyard Industrial Estate (1.3 miles west of Plumstead): one bay, aisle or car park row at a time.

Questions we’re asked in Plumstead

Can you take on a job at a hospital such as Queen Elizabeth Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Do you cover business parks and estates near Plumstead, such as Gateway Business Centre?

Yes. We cover Plumstead and the area around it, including industrial estates, business parks and retail parks such as Gateway Business Centre. Photos and a short description are enough for a first look.

What do you need from us to quote?

Send details through our quote form or by email, with the traffic on each area. A fixed quote follows that shows the products and zones.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we will send them with the quote.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

What site paperwork can you supply?

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.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Why deal with it now?

Some runs only need partial renewal or topping up. If old material is sound on one face and only a fine gap has opened, it may not all have to come out and the quote shows which approach suits each run. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

A quote for floor joints depends on how many there are, their condition and the access, plus any specification you’re working to. Ask us for a fixed quote.
