Slabs, ramps and loading bays in Little London
The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Little London is about 61 miles from central London. The roads out of London are lined with trade parks and distribution sheds.
A healthcare site such as Andover Hospital (Grounds) (to the south-west of Little London) depends on car parks, ramps and service yards whose joints take traffic all day. At places like Walworth Business Park, which lies south of Little London, joints are sealed a section at a time so operations carry on.

About our expansion joint sealing in Little London
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors on sites in Little London. We work on car park decks and ramps, blockwork control joints and cladding panel joints, and what we are called in for most is weathered movement joint sealant that no longer flexes and previous reseals laid over old sealant. A single leaking joint is often how a building in Little London first comes to us: we look at the rest while we’re there and tell you what we find.
In and around smaller places like Little London, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Questions about Little London
Does your area include sites such as Glenmore Trade Park, near Little London?
Yes. Estates, retail parks and business parks around Little London, Glenmore Trade Park among them, are all within reach. Photos and a short description are enough for a first look.
Is Little London too small for you to travel to?
No. Places such as Little London are covered as much as the big towns. 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.
Which product is best for expansion joints?
Movement capability matters most. Where two different materials meet, a hybrid sealant can be the better choice.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Is colour matching possible?
In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Can the building stay open while you work?
In most cases, yes. Phased work can be planned so areas stay in use.
What we are called out for in Little London
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
Most enquiries start with one or more of the following:
- Brittle, chalky sealant on external joints
- Water getting into the wall through a failed joint
- New sealant over old, now failing
- Arrises breaking up along floor joints
Schools like Smannell and Enham Church of England (Aided) Primary School often have long brick elevations with movement joints that age quietly.
What your quote should include
- Whether primer will be used where the manufacturer specifies it
- Will CSCS-carded applicators be on site?
- What the guarantee covers, and for how long
- How the existing material will be dealt with
What sets the cost
We price every job individually. The things that drive the figure:
- Joint width, depth and condition
- Travel to remote or island sites
- Quantities, in metres or numbers
- Removal of failed or old sealant
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Access details, including height
- Approximate linear metres or a joint schedule
- The postcode of the building
- Your programme or deadline
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, phone 01277 525 020 or send details through our quote form.
When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
From enquiry to sign-off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Little London are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- 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.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- A sealant suited to the movement and traffic is laid to depth and tooled.
- Each area is handed back after its cure time, under our 12-month guarantee.
Getting the site ready
- Let building users know which areas are affected
- Tell us your opening times and when work is allowed
- Let us know about inductions and permits

Different surfaces, different methods
Joints between different materials
Some mixed-material joints suit a hybrid sealant. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.
Concrete and precast panel joints
Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.
Looking after the joints
After handover, a little attention goes a long way:
- Include every elevation and deck joint in periodic inspections
- Look over external and deck joints after a hard winter
- Report split or peeling joint sealant early
- Note which joints were done, when, and with what
Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.
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.
