Floor joint sealing for St Mary's Bay sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Wide or random cracking that suggests a structural issue
  • Joint edges that have already broken away, which need repairing before filling (we’ll tell you if so)
  • A failing floor coating, which is a flooring contractor’s job

If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer.

What we seal

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

Floor joint sealing for commercial buildings in St Mary's Bay

It isn’t only heavy industry. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, where a gappy, dirty joint looks untidy and snags castors. A neat, flush fill makes the floor easier to clean and look after. Site teams most often ask us about a gap opening alongside old joint filler and joint edges breaking up under truck wheels, across retail and showroom floors, saw-cut induced joints and joints along racking aisles. Whoever orders the work in St Mary's Bay, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

In a smaller place such as St Mary's Bay, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Concrete floors and yards in these buildings move and crack like any others.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or email the details over and we’ll arrange a return visit.

Why it’s worth doing now in St Mary's Bay

A floor coating laid over open joints soon cracks along the joint lines. The joints have to be filled or sealed as joints before or alongside any coating work. In a smaller place such as St Mary's Bay, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

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

Diagnose, treat, sign off

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Work in places the size of St Mary's Bay 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. Each joint is cut or routed back to clean, sound concrete.
  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.

Advice

Common questions from St Mary's Bay clients

Our building in St Mary's Bay is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Is St Mary's Bay off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

What do you need from us to quote?

A rough joint length, a few photographs and a site plan are typically enough for a quick quote. For larger floors, a site visit is often best, and you can call the office on 01277 525 020 or email a schedule or drawings to arrange it.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

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.

Is the floor joint work guaranteed?

There is a 12-month guarantee on our workmanship and the work is covered by public liability insurance.

What happens if the joint edges are damaged?

We check the edges as part of the survey. Damaged edges are flagged up front so the filling isn’t wasted.

What we are called out for in St Mary's Bay

Pallet-truck and forklift wheels concentrate weight on a tiny contact patch. Crossing an open joint, the wheel drops and knocks the opposite arris, and repeated impacts break the concrete away.

Most enquiries start with something like this:

  • Grimy joint lines spoiling a showroom floor
  • Soft sealant dragged out of trafficked joints
  • Dock area joints that have failed first
  • Filler that has parted from one face

In a school such as The Marsh Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.

What to look for in a quote

  • The terms of the workmanship guarantee
  • How they’ll work around occupants
  • Whether old or failed sealant will be cut out, not overlaid
  • How they handle RAMS and site documents

Questions to ask before you appoint anyone

Where floor joints take the most wear near St Mary's Bay

The sea is no more than about 1 mile from St Mary's Bay. 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. Rainfall across the South East, St Mary's Bay included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint.

In and around St Mary's Bay, the right filler or sealant for each joint depends on the traffic and the movement it takes.

St Mary's Bay is about 6 miles south-west of Hythe, in Kent. We cover St Mary's Bay and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. Our Kent coverage takes in 931 places. There’s a separate page for Brighton, roughly 50 miles from St Mary's Bay.

General trades versus a specialist

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.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
