Expansion joint sealing in St Mary's Bay
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. We work on brickwork movement joints, precast concrete panel joints and blockwork control joints, and what we are called in for most is torn sealant in brick or block movement joints and brittle, chalky sealant on external joints. Whoever orders the work in St Mary's Bay, the brief is typically 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.
Every job we finish is backed by a 12-month workmanship guarantee, in St Mary's Bay as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.
Floors, slabs and movement joints in St Mary's Bay
With the shore within about 1 mile, St Mary's Bay counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, so it pays to keep them sealed. St Mary's Bay is about 57 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.
For floors and slabs around St Mary's Bay, the product is chosen for the traffic and the movement at each joint. In a school such as The Marsh Academy, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact. What matters most for a job in St Mary's Bay is a clear list of what needs doing. A fixed quote follows.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Finished joints are checked and backed by our 12-month guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Let building users know which areas are affected
- Send your site hours and access windows

How the job changes by surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen in a colour confirmed for that product.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them, and tell you if edges need repairing first.
After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Note which joints were done, when, and with what
- Clear dirt from joint lines during routine cleaning
- Act on the first tear or lifting edge rather than waiting
- Check joints after long freezing spells
In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort so you can prioritise and budget. We will tell you which movement joints need doing now and which can wait.

Site staff or a sealant specialist?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Questions we’re asked in St Mary's Bay
Our building in St Mary's Bay is near the coast: does that change the sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Does a site in St Mary's Bay have to shut while its joints are sealed?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Do you guarantee expansion joint work?
A 12-month guarantee covers our workmanship, and we are fully insured for public liability. Keeping joints clear of debris helps them last.
Does weather matter for sealant work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Are expansion joints and movement joints the same thing?
They’re closely related. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
What sealant work can’t fix
We check first that sealant really is the fix. It won’t put right:
- Crumbling edges that would give a new bead nothing sound to grip
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
Not sure which it is? You can speak to us on 01277 525 020 or use the quote form and we’ll tell you honestly.
