Floor joint sealing near Sompting

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

Floor joint sealing in Sompting, done properly

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, area by area where it needs to be. If you have untidy open joints in a retail unit and a gap opening alongside old joint filler, we can help, on construction joints, saw-cut induced joints and retail and showroom floors alike. Whoever orders the work in Sompting, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Rural business units around smaller places such as Sompting often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Structural cracking in the slab
  • Worn screed or surface finishes
  • Unstable slabs moving under traffic

If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think before you book.

Joints and surfaces we work on

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

When to bring in a specialist

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.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Questions we’re asked in Sompting

Is a smaller place like Sompting outside your area?

Not at all. Sompting is within our area. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can being near the sea in Sompting affect the sealant we need?

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.

Is the floor joint work guaranteed?

A 12-month guarantee covers the work we do. It covers our workmanship, not later slab movement or damage from impacts.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we will confirm it when we quote.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you fill joints where the arrises have spalled?

We check the edges as part of the survey. Where they have broken away, we’ll tell you before quoting the filling, so nothing is filled that won’t hold.

Owners, agents and contractors

If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

CHAS accredited and a Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Maintenance after handover

Regular inspection catches problems early. Specifically:

  • Respect the cure time before traffic returns
  • Sweep debris out of open joints until they can be filled
  • Start with the dock areas, where joints fail soonest
  • Check joint lines on busy aisles regularly

We will give you a time before trucks can run over the new joints and it pays to stick to it. Cones or barriers stop the first driver cutting the corner.

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.

On site: what to expect

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Work in places the size of Sompting is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. Zones reopen once cured and the work moves on.

Preparing the site

  • Agree which areas must stay open
  • Share your working hours and any access restrictions
  • Let building users know which areas are affected

Advice

What we are called out for in Sompting

Small, hard wheels put a lot of load through a very small area. Crossing an open joint, the wheel drops and knocks the opposite arris, and repeated impacts break the concrete away.

Things that typically lead to an enquiry:

  • A gap opening alongside old joint filler
  • Sealant pulled out along a truck route
  • Broken arrises where pallet trucks cross
  • Unfilled floor joints collecting dirt and grit

At places like Lancing Business Park (0.7 miles south of Sompting), joints are sealed a section at a time so operations carry on.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • Which product they’ll use, and why it suits the joint
  • The terms of the workmanship guarantee
  • How they’ll work around occupants

Questions to ask before you appoint anyone

Warehouse floors and decks around Sompting

Sompting lies within about 2 miles of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. At least three named trading, business or retail sites lie within about 3 miles of Sompting. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Large sites such as Worthing Hospital, 1.6 miles south-west of Sompting, have car parks, service roads and long elevations with movement joints in brick and panels. Schools such as Sompting Village Primary School have movement joints in their walls and floors that are easy to overlook.
