Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Expansion joint sealing for commercial buildings in Charvil
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. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. If you have expansion joints filled with dirt and stones and damp inside where a wall movement joint has failed, we can help. One point of contact handles commercial sealant work in Charvil from the first photos to the final walk-round, whether it’s one building or several.
In a smaller place such as Charvil, 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.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application.

Why deal with it now?
Resealing is usually the answer, not replacing the element. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we’ll tell you they need repairing first. Small buildings around Charvil suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Floors, slabs and movement joints in Charvil
The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. At about 34 miles from central London, Charvil is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.
At places like Castle End Business Park (2.1 miles north-east of Charvil), joints are sealed a section at a time so operations carry on. Retail parks like Loddon Vale Shopping Centre, 1.5 miles south of Charvil, have long runs of car park and yard joints taking daily traffic. Schools like Waingels College often have long brick elevations with movement joints that age quietly.

Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Clear dirt from joint lines during routine cleaning
- Inspect movement joints alongside other routine building checks
- Report split or peeling joint sealant early
- Avoid parking heavy plant or pallets on joint lines
Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in. If anything looks wrong, call 01277 525 020 or email a schedule or drawings with photographs.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a site in Charvil, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- We check every joint before sign-off, and the work carries our 12-month guarantee.

How the job changes by surface
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond.
Podium joints
Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:
- Structural movement beyond what the joints were designed for (that needs a structural engineer)
- Waterproofing layers buried beneath the sealant
- Joints too narrow for the movement, which need redesigning by the engineer
If you are not sure, just call 01277 525 020 or send photos by email and we will give you a straight answer.
Surfaces we seal
- Car park decks and ramps
- Cladding panel joints
- Podiums and floor movement joints

Your questions answered
Can you work at a site such as Loddon Vale Shopping Centre, by Charvil?
Yes. Estates, retail parks and business parks around Charvil, Loddon Vale Shopping Centre among them, are all within reach. Photos and a short description are enough for a first look.
Is Charvil off your patch?
Not at all. Charvil is within our area. We work across Greater London and 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.
Is any job too small?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What about RAMS and site documents?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Can you quote from photographs?
It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
