When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Damaged metal nosings or cover plates over a joint
- Leaks coming from the membrane rather than the joint seal
- Crumbling edges that would give a new bead nothing sound to grip
Not sure which it is? You can call the office on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we look at:
- Whether the work must be split into stages
- Location, for remote and island sites
- Backing rod, priming and other preparation
- The total length or number of joints
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Rough lengths or quantities, or drawings if you have them
- A wide shot and a close-up of the area
- What the building is and how it’s used
- Any dates the work must fit around
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.
On site: what to expect
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Leverton are normally planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
What we need from you
- Tell us which areas need to stay in use
- For older buildings, check the asbestos register before work
- Flag any permit to work we will need
Quotes
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email us.

Expansion joint sealing around Leverton: how the place shapes the job
Less than 3 miles from Leverton there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. At about 62 miles from central London, Leverton is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day.
Another example is Hungerford Trading Estate (1.2 miles south of Leverton), where floors and yards would be done in stages around the occupiers. For buildings at a park such as Charnham Business Park, 0.7 miles south-east of Leverton, brick and panel movement joints are easy to forget until one leaks.

When to call us in Leverton
Sometimes the sealant holds but the substrate breaks away. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip, so we tell you if the edges need repairing first.
What tends to prompt an enquiry:
- Expansion joints split through the centre of the bead
- Leaks through car park deck joints onto the level below
- Joints packed with grit and debris
- Hardened, cracked sealant on exposed facades
In a school such as Chilton Foliat Church of England Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.
What to look for in a quote
- Can the work be phased to keep areas open?
- How long is the guarantee, and what does it include?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Do they follow the manufacturer’s priming guidance?
How the job changes by surface
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.
Podium joints
Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix and flag it if the membrane looks like the source.
Common questions from Leverton clients
Must our site in Leverton stop work while the joints are done?
In most 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’ll plan from there.
Is Leverton off your patch?
No. Places such as Leverton are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
When can the area be used after sealing?
We’ll confirm how long the chosen product needs to cure.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
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 work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
