Floor joint sealing in Lancing

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How the job changes by surface

Loading bays and dock areas

Joints at dock doors need a product that copes with the traffic and the conditions. Phasing is planned around your delivery schedule.

Saw-cut induced joints

Sawn joints make up most of the joint length in a typical industrial floor. We clear them back to clean concrete and fill them to the depth the product calls for with a flush finish.

Floor joint sealing in Lancing

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so if the edges need repair before any filling, we will say so and leave that decision with you. If you’re dealing with filler that has parted from one face and chipped and spalling edges along forklift routes, we can put it right, on retail and showroom floors, forklift and pallet-truck routes and construction joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Lancing it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

Around places the size of Lancing, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.

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

Why deal with it now?

Dirt and spillage gather in open joints where scrubber-driers can’t get it out. In shops, showrooms and clean production areas that matters for hygiene and appearance. Flush, filled joints leave nothing for cleaners to dig out. For buildings in places like Lancing, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why clients in Lancing choose us

  • Fully insured, including public liability cover
  • Clear, fixed quotes
  • One contact handling all your sites
  • Work to your specification and the manufacturer’s guidance

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:

  • Wide or random cracking that suggests a structural issue
  • A failing floor coating, which is a flooring contractor’s job
  • Slab panels that rock or move under load

If you’re not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

Joints and surfaces we work on

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

Aftercare for building managers

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

  • Respect the cure time before traffic returns
  • Start with the dock areas, where joints fail soonest
  • Clear packed debris from open joints regularly
  • Mention any aggressive cleaning regime at quote stage

On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. That is common and is normally dealt with by topping up once the slab has settled down in most cases.

Every day an open joint stays full of grit, the edges take more punishment. Getting it filled stops the damage before it becomes a repair.

How the quote is worked out

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Access and working height
  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits
  • Which sealant the job calls for

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Details that help us quote

A few photos plus some basic facts will normally do. It helps to include:

  • Access details, including height
  • The site address and postcode
  • Whether the building will be occupied during the work
  • Photos of the joints, close up and from further back

For a fixed quote, call the office on 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. Our quote form is another easy route.

Your questions answered

Is a hospital such as Worthing Hospital somewhere you can work?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

Does a coastal location like Lancing affect which sealant is used?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

Do you use semi-rigid filler or flexible sealant on floor joints?

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

How soon can traffic go back on the floor?

Each product has its own cure time, and cold floors slow it down. Phasing is planned with that in mind.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and we will price the work to it.

How do you choose the sealant?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Diagnose, treat, sign off

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. What matters most for a job in Lancing is a clear list of what needs doing, so send photographs of each area. A fixed quote follows.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. You get a fixed quote with the product and the phasing set out.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Preparing the site

  • Warn occupants and staff about the work
  • Have the specification and drawings to hand
  • Point out any areas we must not close

Getting a fixed quote

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, ring 01277 525 020 or send details through our quote form.

Warehouse floors and decks around Lancing

Lancing lies within about 1 mile of the sea. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, and edges left open tend to break up faster. Lancing is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, while winter salting gets into any joint left open.

Office parks like Lancing Business Park (to the south-west of Lancing) have decks, ramps and clad elevations whose joints take movement every day. Large sites such as Worthing Hospital (to the south-west of Lancing) have car parks, service roads and long elevations with movement joints in brick and panels. Phasing is what makes joint work possible on busy sites such as Rectory Farm Road Business Park (0.9 miles north-west of Lancing): one bay, aisle or car park row at a time.

Lancing is about 3 miles east of Worthing, in West Sussex. Commercial clients in Lancing use us for work on floor joints. We work across 373 places in West Sussex. Our Brighton page has more on work in that area (8 miles or so).
