How the job changes by surface
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.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement.
How we handle expansion joint sealing in Riverhead
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in. Resealing at the first signs of failure is far cheaper than repairing the material either side. The enquiries we see most involve joints packed with grit and debris and rain penetration at brick or block movement joints, on cladding panel joints, podiums and floor movement joints and brickwork movement joints. A single leaking joint is often how a building in Riverhead first comes to us: we look at the rest while we are there and tell you what we find.
Around places the size of Riverhead, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.
Our workmanship is guaranteed for 12 months, in Riverhead as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

FAQs: Riverhead
Would you work within a site like Sevenoaks Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Riverhead off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or email us. Include photos or drawings if you have them.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
What site paperwork can you supply?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
What we can’t put right
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Cracking or settlement that calls for an engineer’s assessment
- Leaks coming from the membrane rather than the joint seal
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly.
What we seal
- Blockwork control joints
- Precast concrete panel joints

Expansion joint sealing around Riverhead: points for this area
The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. At about 19 miles from central London, Riverhead is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London, and their floor joints take forklift and pallet-truck traffic all day.
Phasing is what makes joint work possible on busy sites such as Sevenoaks Business Centre (1.1 miles north-east of Riverhead): one bay, aisle or car park row at a time. Schools such as Amherst School have movement joints in their walls and floors that are easy to overlook.
Riverhead is about 1 mile west of Sevenoaks, in Kent. Across the TN13 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Kent coverage takes in 931 places, from busy centres to rural villages. For work in that direction, see our London page (19 miles or so).
Commercial sites across TN13 and TN14 are covered for movement joints. We cover commercial and managed buildings on London Road, Hamlin Road and Witches Lane. Close to Riverhead, our area also takes in Dunton Green (1 mile north), Bessels Green (1 mile south-west), Sevenoaks (1 mile east), Chipstead (1 mile west) and Kippington (1 mile south). A short drive away, we cover Maidstone (15 miles east), Dartford (11 miles north), Royal Tunbridge Wells (11 miles south), Gravesend (14 miles north-east), Tonbridge (8 miles south-east) and Northfleet (13 miles north-east).
Landmarks near Riverhead

The closest station to Riverhead is Sevenoaks station, about 0.8 miles south-east. Well-known places in the area include Kemsing Castle Bank (3 miles north-east) and Sevenoaks Museum (1.4 miles south-east). Not far away are Dryhill Nature Reserve and Betsom's Hill.
Aftercare for building managers
A few simple habits keep the new joints working:
- Raise snow-clearing blades over deck joints where possible
- Plan racking layouts so feet don’t land on a joint
- Reopen bays and walkways only after the stated cure time
- Record the sealant used and the date in the O&M file
Every joint we seal is backed by a 12-month guarantee on workmanship. Keep the handover details, product and date with your O&M records so future maintenance isn’t guesswork.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.
When to call us in Riverhead
Car park decks and floors face loads that walls never see. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.
Common reasons buildings call us in:
- Joints packed with grit and debris
- Weathered movement joint sealant that no longer flexes
- Water getting into the wall through a failed joint
- Sealant peeling off one face of the joint
Office parks like Salters Heath Business Centre, 0.9 miles south-west of Riverhead, have decks, ramps and clad elevations whose joints take movement every day.

On site: what to expect
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. What matters most for a job in Riverhead is a clear list of what needs doing. You’ll then get a fixed price for the work.
- First the joints are inspected, widths measured and the type of failure noted.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- 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.
Getting the site ready
- Warn occupants and staff about the work
- Share your working hours and any access restrictions
- Move anything stored against the joints
