How we handle floor joint sealing in New Malden

Few warehouses can shut a whole floor while joints are done, so we phase the work aisle by aisle or bay by bay. Share your site hours and access windows and the programme is built around them so the rest of the operation keeps going. We work on joints along racking aisles, forklift and pallet-truck routes and saw-cut induced joints, and the failures we’re asked to look at most are untidy open joints in a retail unit and loading bay joints breaking down. Most enquiries from New Malden start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. In New Malden, as everywhere in London, access, loading and the ULEZ all come into the plan.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Floor joint sealing around New Malden: how the place shapes the job

Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a day for smaller units, with bigger warehouse floors programmed over several visits, and we clear our waste as we work. Planning a London job such as one in New Malden starts with access. Send the building rules and access times with your enquiry.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. The quote fixes the price, names the filler or sealant and shows how the floor will be zoned.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  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.

Preparing the site

  • Share your working hours and any access restrictions
  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Surface by surface

Construction joints

Day joints vary, with or without armoured edges. If the edges look unsound, we’ll say so before any filling is done.

Semi-rigid joint fillers

For trafficked warehouse joints, semi-rigid fillers are common. They are installed to the depth the manufacturer specifies and finished flush.

Common questions from New Malden clients

Does your area include sites such as Shannon Commercial Centre, near New Malden?

Yes, sites like Shannon Commercial Centre are within our area, along with the rest of New Malden. A few photos and the unit address let us price the work.

Can you cope with the access rules in a London building?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We will confirm the colours available for the specified product.

How do you choose the sealant?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units 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.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

When to call us in New Malden

A soft, flexible sealant on a forklift route can’t hold the arrises up and the edges fail regardless. It can go the other way too: a stiff filler in a joint that keeps moving splits or comes away from the sides.

If one of these sounds familiar, it’s time for a closer look:

  • Loading bay joints breaking down
  • Soft sealant dragged out of trafficked joints
  • Saw-cut joints left open and packed with grit
  • Joint fill separating from the concrete

Office parks like Shannon Commercial Centre (0.8 miles east of New Malden) have decks, ramps and clad elevations whose joints take movement every day.

Questions to ask before you book

  • Their approach to joint depth and backing
  • Health and safety accreditation such as CHAS
  • How long is the guarantee, and what does it include?
  • How they handle RAMS and site documents
