Expansion joint sealing around Clement Street: how the place shapes the job
At about 14 miles from central London, Clement Street 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. Clement Street has at least three named business or industrial parks inside a 3-mile radius. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
At places like Mills Trading Estate, 1.7 miles south-east of Clement Street, joints are sealed a section at a time so operations carry on. On a site such as Button Street Business Park, 0.8 miles south of Clement Street, the movement joints are in car park slabs, paving and building elevations.
Clement Street is about 2 miles south of Dartford, in Kent. We cover Clement Street, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Clement Street is one of 931 places we cover in Kent. London is covered too, some 14 miles away.

About our expansion joint sealing in Clement Street
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. 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. We work on blockwork control joints, car park decks and ramps and cladding panel joints, and the usual reasons a site gets in touch are sealant peeling off one face of the joint and weathered movement joint sealant that no longer flexes. A single leaking joint is often how a building in Clement Street first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Clement Street, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, speak to us on 01277 525 020 or email us and we will arrange a return visit.

Do you need expansion joint sealing in Clement Street?
Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks and opens at the next temperature swing.
Look out for the following:
- Debris jammed in movement joints
- Brittle, chalky sealant on external joints
- Movement joints with split or torn sealant
- Leaks through car park deck joints onto the level below
Schools such as Sutton-At-Hone Church of England Primary School have movement joints in their walls and floors that are easy to overlook.

Leave it or put it right?
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use, compared with a full closure. Tell us what has to stay open and we will plan around it. Converted and older buildings near places like Clement Street tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Different surfaces, different methods
Joints between different materials
Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves.
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.
Common questions from Clement Street clients
Is hospital work, at somewhere like Darent Valley Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Is Clement Street too small for you to travel to?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Are you insured?
Yes. Our insurance certificate can be sent alongside the quote.
Is any job too small?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.
Cost factors for movement joints
We price every job individually. The things that drive the figure:
- The total length or number of joints
- Site requirements such as inductions and permits
- How accessible the joints are
- How much existing material needs removing
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
Before you send an enquiry
Good information means a firmer quote. Helpful details to send:
- Anything awkward about access or site hours
- Any dates the work must fit around
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or ring 01277 525 020 or email drawings and photos if you’d rather talk the job through.
Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Keep traffic off new joints until the cure time is up
- Avoid parking heavy plant or pallets on joint lines
- Raise snow-clearing blades over deck joints where possible
- Note which joints were done, when, and with what
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. Regular sweeping keeps joint lines clear.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster. Sealing early protects the edges.
How a job runs
Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a building around Clement Street, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- 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.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
Preparing the site
