Our process
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. For work around Launton, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.
- First, the joints are inspected for width, movement and the type of failure.
- Next, we fix a price and confirm the sealant we propose for the movement.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Tell us which areas need to stay in use
- Tell us your opening times and when work is allowed

About our expansion joint sealing in Launton
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. Site teams most often ask us about sealant peeling off one face of the joint and water getting into the wall through a failed joint, on blockwork control joints, cladding panel joints and precast concrete panel joints. Whoever orders the work in Launton, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For a site near Launton, measurements and photos up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Questions about Launton
Is Launton off your patch?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Will you take on work at estates like Telford Road Industrial Estate, close to Launton?
Yes, sites like Telford Road Industrial Estate are within our area, along with the rest of Launton. Photos and a short description are enough for a first look.
Do the joint edges need to be sound before sealing?
Sound edges are essential. If they’re damaged, we’ll say so before any sealing.
What if there’s asbestos in the old mastic?
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. We don’t remove asbestos-containing materials.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Do you reseal car park expansion joints?
Yes, we do. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed and broken edges are flagged before sealing.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
What happens if it’s left?
Some quotes just add sealant over the old bead. A bead over the old seal can’t bond or flex, so it fails quickly. We cut out the old seal and prepare the faces every time. For buildings around smaller places like Launton, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

After the work
Once the work is signed off, these steps help:
- Include every elevation and deck joint in periodic inspections
- Keep racking legs and heavy point loads off floor joints
- Treat a small split as a warning, not a cosmetic issue
- Clear dirt from joint lines during routine cleaning
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.
Traffic, movement and joints around Launton
Launton 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. Central London is about 52 miles from Launton. Warehousing clusters around the motorways that ring and radiate from London.
Schools such as Launton Church of England Primary School have movement joints in their walls and floors that are easy to overlook. Sites like Bicester Community Hospital (to the west of Launton) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Launton is about 2 miles east of Bicester, in Oxfordshire. We cover Launton and the rest of Oxfordshire, with the same fixed quotes and 12-month guarantee as everywhere else. Our Oxfordshire coverage takes in 423 places. For work in that direction, see our Oxford page (11 miles or so).
Anyone looking for expansion joint sealing in OX26 and OX25 gets the same process as the rest of our area: send details, get a quote, we seal, guaranteed. Among the streets we cover are Station Road, Skinner Road and Ancil Avenue, and sites on any of them can send details for a fixed quote. Nearby places we also cover include Ambrosden (2 miles south), Lower Arncott (3 miles south), Chesterton (3 miles west), Upper Arncott (3 miles south) and Wendlebury (3 miles south-west) for movement joints. A short drive away, we cover Oxford (11 miles south-west), Banbury (15 miles north-west), Thame (12 miles south-east), Kidlington (9 miles south-west), Headington Quarry (10 miles south) and St John Street area (12 miles south-west).
What’s near Launton
Locally, jobs take us to sites close to Cooper School and The Bull Inn and the streets around them. The nearest railway station is Bicester North station, about 1.4 miles west of the centre. A little further out are Bicester Village (1.7 miles west) and Bicester Community Hospital (1.7 miles west). Not far away are Graven Hill and Upper Ray Meadows.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Leaks coming from the membrane rather than the joint seal
- Joints too narrow for the movement, which need redesigning by the engineer
- Damaged metal nosings or cover plates over a joint
If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.
What we seal
- Brickwork movement joints

General trades versus a specialist
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
What we’re called out for in Launton
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:
- Spalled or broken joint edges in floors and decks
- New sealant over old, now failing
- Movement joints with split or torn sealant
- Water dripping through deck or ramp joints
Phasing is what makes joint work possible on busy sites such as Talisman Business Centre (1.4 miles west of Launton): one bay, aisle or car park row at a time.
