Expansion joint sealing in Charlton, done properly
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. If you have layers of sealant in a movement joint and sealant peeling off one face of the joint, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Charlton tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Smaller community and commercial buildings around Charlton have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Our workmanship is guaranteed for 12 months, wherever the site is. If our installation lets you down in that time, we return and fix it.

Leave it or put it right?
A torn seal left alone usually gets worse. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Converted and older buildings near places like Charlton tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Pricing movement joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Common questions from Charlton clients
Do we have to stop operations in Charlton while the joints are sealed?
In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.
Can you work on a hospital site such as Chichester Centre?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
How long will the joint resealing take?
Expect a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases and phased work can stretch that to suit your site. Cure time before reopening is confirmed on the day.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use.
Do you take on small jobs?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
After the work
To get the most from the new sealant:
- Look over external and deck joints after a hard winter
- Sweep decks, ramps and floors so grit doesn’t collect in the joints
- Keep racking legs and heavy point loads off floor joints
- Inspect movement joints alongside other routine building checks
Floor joints on main traffic routes need watching more closely than the rest. Keep racking feet and heavy point loads off joint lines and flag chipped arrises before they spread.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Sealing early protects the edges.

Joints that move: notes for Charlton
Charlton is about 49 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. Charlton is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.
For estates staff at a university like University of Chichester (4.7 miles south of Charlton), building and paving joints are part of the planned maintenance list. A healthcare site such as Chichester Centre (4.6 miles south of Charlton) depends on car parks, ramps and service yards whose joints take traffic all day.
Charlton is about 5 miles north of Chichester, in West Sussex. Any commercial site in Charlton is covered, whether it’s a single job or part of a planned programme. Across West Sussex, 373 places are covered, including Charlton. Our Portsmouth page has more on work in that area (16 miles or so).

Common problems we fix in Charlton
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.
What tends to prompt an enquiry:
- Car park joints leaking onto vehicles below
- Joints where the bead has lost adhesion
- Expansion joints split through the centre of the bead
- Arrises breaking up along floor joints
For a school such as Singleton CofE Primary School, playground and building joints can be done in the holidays.

Our process
At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Charlton need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- 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.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Explain the parking and delivery arrangements
- Confirm the product named in the specification
- Share the asbestos register for older buildings
