Why act early in Wallington

Every jolt over a broken joint passes into the truck, the load and the driver. That means extra wear on wheels and a rougher ride for staff, adding costs nobody plans for. A filled joint takes most of that out. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.

A quote for floor joints depends on how many there are, their condition and the access. Ask us for a fixed quote.

Why us?

  • A Constructionline member, so easy to vet
  • Work carried out by CSCS-carded applicators
  • Fully insured, including public liability cover
  • One contact handling all your sites

Floor joint sealing in Wallington, done properly

Open joints take a beating from forklift and pallet-truck wheels. Every pass chips at the bare concrete edge until a crisp saw cut becomes a wide, broken groove. Filling the joint properly gives the edges back their support, which is kinder to trucks, loads and operators. Site teams most often ask us about filler that has parted from one face and open saw cuts full of debris, across loading bays, joints along racking aisles and retail and showroom floors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Wallington, that means joint design, primers and backing rod as standard.

Areas such as a loading bay or car park deck in Wallington usually have to stay in use. Joints are done in sections, with bays coned off one after another, so the site keeps operating.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or more, depending on the metres of joint and how many zones the floor is split into, and our waste is bagged and taken away as we go. 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. We walk the floor and mark up joint widths, edge damage and traffic routes.
  2. The treatment and the zones are set out in a fixed quote.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. We extract the dust and prime the faces if the product needs it.
  5. The joint is filled to its specified depth and trimmed level.
  6. We hand each phase back when it can take traffic.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Tell staff and tenants when we’ll be in
  • Move anything stored against the joints

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.

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

What we’re called out for in Wallington

An ageing filler or sealant can go brittle and split, particularly where cleaning machines and traffic work it daily. Once it has gone hard or come loose, it protects nothing.

Clients normally get in touch after noticing one or more of the following:

  • Loading bay joints breaking down
  • Untidy open joints in a retail unit
  • Unfilled floor joints collecting dirt and grit
  • A gap opening alongside old joint filler

Retail centres such as Whitgift Centre (to the east of Wallington) have floors, service yards and car parks with joints under constant traffic.

What your quote should include

  • Their approach to joint depth and backing
  • Will RAMS and insurance details be available?
  • Who will actually carry out the work
  • Are they CHAS accredited or on Constructionline?

How to choose a sealant contractor

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)
  • Structural cracking in the slab
  • Level or flatness problems across the floor

If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

What we seal

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

When to bring in a specialist

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

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.

Common questions from Wallington clients

Is a hospital such as Queen Mary's Childrens' Hospital somewhere you can work?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Can you work at a site such as Anchor Business Park, by Wallington?

Yes. Our area takes in Wallington and its surroundings, with estates and business parks such as Anchor Business Park included. Send details of the unit and the work through our quote form for a quick quote.

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.

Is colour matching possible?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

How do we get a quote for floor joints?

Use our quote form, or email photos and a plan and tell us what runs on the floor. We then send a fixed quote that shows the products and zones.

Can you phase floor joint work around operations?

The work is phased. We work aisle by aisle or zone by zone so the rest of the floor stays in use. Tell us your site hours and access windows and we’ll plan around them.

What happens if the joint edges are damaged?

Filling against broken edges doesn’t last. We will tell you if the joint edges need repairing first and set out how that affects the job.

Traffic, movement and joints around Wallington

Less than 3 miles from Wallington 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. In London, decks, bays and service yards normally have to keep running, so joints are sealed in sections with each area handed back once cured.

Across sites such as Silver Wing Industrial Estate (1.2 miles east of Wallington), floor and movement joints can be sealed in phases so units keep working. Hospital campuses such as Queen Mary's Childrens' Hospital (1.8 miles north-west of Wallington) grow in stages, leaving movement joints wherever new blocks meet old.
