Floor joint sealing near Downton

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

When something else is needed

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Joint edges that have already broken away, which need repairing before filling (we will tell you if so)
  • Level or flatness problems across the floor
  • Worn screed or surface finishes

If you’re not sure, just ring 01277 525 020 or send details through our quote form and we will give you a straight answer.

What we seal

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

About our floor joint sealing in Downton

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. We fill or seal them with a product matched to the traffic and the movement so the edges are held up and debris can’t pack in. We work on saw-cut induced joints, construction joints and loading bays, and the usual reasons a site gets in touch are grimy joint lines spoiling a showroom floor and joint edges breaking up under truck wheels. A single leaking joint is often how a building in Downton first comes to us: we look at the rest while we’re there and tell you what we find.

For a site near Downton, measurements and photos up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

On site: what to expect

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a building around Downton, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

What we need from you

  • Explain the parking and delivery arrangements
  • Clear stock, furniture or equipment away from the joints
  • Let us know about inductions and permits

What the job involves on each surface

Saw-cut induced joints

Open saw cuts collect grit and break at the arris. Filling them early keeps them tidy and protects the edges.

Construction joints

Some construction joints have steel edge protection, others are plain concrete. If the edges look unsound, we will say so before any filling is done.

After the work

After handover, a little attention goes a long way:

  • Record damaged joints with a photo and a location
  • Stop forks and pallets being dragged across joints
  • Tell us about strong cleaning chemicals before we quote
  • Expect fillers on young slabs to need a top-up

A routine walk of the busiest aisles shows how the joints are holding up. Look for separation down one side, new chips in the arris and debris gathering, and photograph anything that changes.

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.

Floor joint sealing in Downton: the local picture

The sea is no more than about 1 mile from Downton. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so a failed joint lets more in and the edges break up sooner. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

If you manage units on an estate such as Gore Road Industrial Estate, 2.4 miles to the west of Downton, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. A healthcare site such as Lymington New Forest Hospital (3.7 miles north-east of Downton) depends on car parks, ramps and service yards whose joints take traffic all day. For a school such as Hordle CofE (VA) Primary School, playground and building joints can be done in the holidays.

Downton is about 3 miles west of Lymington, in Hampshire. Anywhere in SO41, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 723 places across Hampshire fall within our area, including Downton. Southampton is covered too, around 16 miles from Downton.

We cover the SO41 postcode districts for floor joints. Among the streets we cover are Hordle Lane and Shorefield Road, and sites on any of them can send details for a fixed quote.

Your questions answered

Is a smaller place like Downton outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Is Gore Road Industrial Estate, near Downton, within your area?

Yes. Estates, retail parks and business parks around Downton, Gore Road Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

Can the sealant be colour-matched?

In many cases, 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.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Which is better for warehouse joints, filler or sealant?

The answer comes from the traffic and the joint’s movement. Forklift routes generally call for a semi-rigid filler that holds the arrises, while joints that move more take a flexible sealant.

How long will the new sealant last?

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

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Building owners and managing agents use us on everything from one building to a spread of sites around Downton. One quote can cover more than one site, which keeps the paperwork simple.

Should maintenance staff do it?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
