Expansion joint sealing in Kingswood
The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. Site teams most often ask us about rain penetration at brick or block movement joints and arrises breaking up along floor joints, across podiums and floor movement joints, blockwork control joints and cladding panel joints.

In and around smaller places like Kingswood, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Proprietary pre-formed expansion joint systems
- Changing the joint layout or spacing of a structure
- Crumbling edges that would give a new bead nothing sound to grip
If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.

What the job involves on each surface
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again.
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Slabs, ramps and loading bays in Kingswood
Rainfall across the South East, Kingswood included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. At about 46 miles from central London, Kingswood is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.
In a school such as Grendon Underwood Combined School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

FAQs: Kingswood
Will you take on work at estates like Lawn Farm Business Centre, close to Kingswood?
Yes, sites like Lawn Farm Business Centre are within our area, along with the rest of Kingswood. Send details of the unit and the work through our quote form for a quick quote.
Is a smaller place like Kingswood outside your area?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work on car park ramps and decks?
Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.
What happens if old sealant might contain asbestos?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. 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. Removing asbestos is a job for asbestos specialists, not us.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Can the building stay open while you work?
Usually, yes. Phased work can be planned so areas stay in use.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Keep racking legs and heavy point loads off floor joints
- Keep scrapers and ploughs from dragging across joint sealant
- Treat a small split as a warning, not a cosmetic issue
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check. If anything looks wrong, ring 01277 525 020 or use the quote form with photographs.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. Keeping the seal sound avoids all of that.
Doing it in-house
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Diagnose, treat, sign off
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. Smaller jobs around Kingswood can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Share your working hours and any access restrictions
- For older buildings, check the asbestos register before work
- Point out any areas we must not close

What tends to prompt an enquiry:
- Water getting into the wall through a failed joint
- Sealant peeling off one face of the joint
- Weathered movement joint sealant that no longer flexes
- New sealant over old, now failing

- Do they follow the manufacturer’s priming guidance?
