What we can’t put right
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:
- Joints too narrow for the movement, which need redesigning by the engineer
- Concrete or masonry repairs along the arrises
- Movement on a scale no sealant is meant to absorb
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Expansion joint sealing in Little Coxwell
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Little Coxwell. If you’re dealing with leaks through car park deck joints onto the level below and previous reseals laid over old sealant, we can put it right, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, in Little Coxwell it comes down to the same thing: the right product in a properly prepared joint.
Halls, schools and small commercial buildings near places like Little Coxwell have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.
We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Our process
Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For a building around Little Coxwell, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
What we need from you
- Have the specification and drawings to hand
- Make sure the joints can be reached
- For older buildings, check the asbestos register before work

How the job changes by surface
Cladding panel joints
Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.
Podium joints
Podium decks are exposed and often trafficked. We choose a product that copes with feet, wheels and weather.
Expansion joint sealing in Little Coxwell: the local picture
At about 65 miles from central London, Little Coxwell is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors. Little Coxwell sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
For an estate such as Faringdon Day Hospital, 1.2 miles north of Little Coxwell, the joints in ramps, decks and long building elevations all need attention over time. Parks like Faringdon Business Park, 0.5 miles west of Little Coxwell, combine paved areas, car parks and building elevations, each with joints that move.

Common problems we fix in Little Coxwell
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.
If one of these sounds familiar, it’s time for a closer look:
- Sealant pulling off the joint face
- New sealant over old, now failing
- Chipped joint edges on forklift routes
- Leaks through car park deck joints onto the level below
Schools such as Faringdon Community College have movement joints in their walls and floors that are easy to overlook.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Health and safety accreditation such as CHAS
- Their public liability cover
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
When to bring in a specialist
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Aftercare for building managers
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Treat a small split as a warning, not a cosmetic issue
- Leave barriers in place until fresh joint sealant has cured
- Keep stones and debris out of open joint lines
- Look over external and deck joints after a hard winter
On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal.
When one joint fails, others of the same age are rarely far behind. Inspecting the whole run is worth the effort so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.
FAQs: Little Coxwell
Can you work at a site such as Faringdon Business Park, by Little Coxwell?
Yes, sites like Faringdon Business Park are within our area, along with the rest of Little Coxwell. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Is a smaller place like Little Coxwell outside your area?
Not at all. Little Coxwell is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Can you fit around our working hours?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Can you seal joints in cold or wet weather?
Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside, so we plan with the forecast in mind.
How long before the joints can be used?
Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.
Will you come and look before quoting?
Many jobs can be quoted from photographs, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Who decides which product is used?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
