Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Our process
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For a building around Radwinter, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- Next, we fix a price and confirm the sealant we propose for the movement.
- We strip out the old seal and prepare the faces.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Finished joints are checked and backed by our 12-month guarantee.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Send asbestos survey details if the building is pre-2000
- Agree which areas must stay open

Expansion joint sealing in Radwinter, done properly
Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side, so failed seals soon lead to leaks onto the level below and broken edges. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. Most enquiries involve expansion joints split through the centre of the bead and water dripping through deck or ramp joints, on car park decks and ramps, precast concrete panel joints and podiums and floor movement joints. A specialist sealant contractor works differently from a general builder: on jobs in Radwinter, preparation and product choice get the time they need.
Halls, schools and small commercial buildings near places like Radwinter have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the job changes by surface
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it.
Internal floor movement joints
Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them.
Looking after the joints
Once the work is signed off, a little attention goes a long way:
- Look over external and deck joints after a hard winter
- Keep scrapers and ploughs from dragging across joint sealant
- Include every elevation and deck joint in periodic inspections
- Act on the first tear or lifting edge rather than waiting
Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. A routine sweep is the simplest protection.
Unsupported floor joint edges spall under forklift and pallet-truck wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Sealing early protects the edges.
Slabs, ramps and loading bays in Radwinter
The South East is one of the drier parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint. Central London is about 40 miles from Radwinter. The roads out of London are lined with trade parks and distribution sheds.
For an estate such as Saffron Walden Community Hospital, 3.6 miles west of Radwinter, the joints in ramps, decks and long building elevations all need attention over time. Schools like Radwinter Church of England Voluntary Aided Primary School often have long brick elevations with movement joints that age quietly.
Radwinter is about 4 miles east of Saffron Walden, in Essex. Across the CB10 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Essex coverage takes in 644 places, from busy centres to rural villages. Sites around London have their own page, about 40 miles away.
We cover the CB10 postcode districts. If your site is on East View Close, Water Lane and Gillon Way or close by, send details and we will quote for movement joints. If your building is just outside Radwinter, we cover The Common (1 mile north), Maple End (1 mile west), Wimbish (1 mile south-west), Hempstead (2 miles east) and Church End (3 miles north-west). Bigger towns within reach include Braintree (13 miles south-east), Saffron Walden (4 miles west), Halstead (14 miles east), Great Dunmow (10 miles south), Stansted Mountfitchet (10 miles south-west) and Great Notley (13 miles south-east).

Common questions from Radwinter clients
Is Radwinter too small for you to travel to?
Not at all. Radwinter is within our area. 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 a hospital site such as Saffron Walden Community Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is movement joint sealing guaranteed?
Our workmanship on movement joints carries a 12-month guarantee. The guarantee covers how we sealed, not damage caused afterwards.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Can staff carry on working while you’re here?
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 take on small jobs?
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.
Why deal with it now?
A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Resealing early keeps the work to sealant. Converted and older buildings near places like Radwinter tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

What sealant work can’t fix
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Joints too narrow for the movement, which need redesigning by the engineer
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Cracking or settlement that calls for an engineer’s assessment
If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
