How the job changes by surface
Brickwork and blockwork joints
A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing.
Car park decks and ramps
Water coming through deck joints is the usual first sign. The old seal comes out, the edges are prepared and the joint resealed flagging broken edges along the way.
Expansion joint sealing in Romney Street, done properly
Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap. A sealant suited to traffic and the expected movement goes in and the work can be phased so parts of the car park stay open. We work on cladding panel joints, blockwork control joints and precast concrete panel joints, and the failures we are asked to look at most are spalled or broken joint edges in floors and decks and previous reseals laid over old sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Romney Street, that means joint design, primers and backing rod as standard.
Smaller community and commercial buildings around Romney Street have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

What we are called out for in Romney Street
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. Movement capability is set out in BS EN ISO 11600.
Common reasons buildings call us in:
- Torn sealant in brick or block movement joints
- Sealant peeling off one face of the joint
- Debris jammed in movement joints
- Weathered movement joint sealant that no longer flexes
At places like Blue Chalet Industrial Park (1.8 miles north-east of Romney Street), joints are sealed a section at a time so operations carry on.

What else we do in Romney Street
Romney Street: questions and answers
Can you work on a hospital site such as Sevenoaks Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Romney Street too small for you to travel to?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
What happens if it rains on the day?
A wet joint can’t be sealed properly. We agree a revised date with you.
Can you work on car park ramps and decks?
Yes. Let us know the opening hours and which levels or bays have to stay available and we will plan around them.
What’s the quickest route to a quote?
You can use the quote form on this site; alternatively, give us a call on 01277 525 020 or send photos by email. Include photos or drawings if you have them.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Why act early in Romney Street
A torn seal left alone usually gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Halls, stores and units around places like Romney Street may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Cost factors for movement joints
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- How much existing material needs removing
- Distance, for remote addresses
- Access and working height
- Joint width, depth and condition
We don’t publish prices, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
Sending details for a quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Whether an asbestos survey exists
- Any specification or named product
- Drawings or a marked-up plan, if available
- Access details, including height
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Our process
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself normally taking a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. If others near Romney Street need work, visits can be combined. You will have a fixed quote before work starts.
- Photos, joint lengths and drawings come to us, or we visit.
- 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.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
Before we start on site
- Flag any permit to work we’ll need
- Make sure the joints can be reached
- Tell us your opening times and when work is allowed

After the work
Regular inspection catches problems early. Specifically:
- Keep scrapers and ploughs from dragging across joint sealant
- Plan racking layouts so feet don’t land on a joint
- Put movement joints on the planned maintenance inspection round
- Note which joints were done, when, and with what
Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.
Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers, and the damage spreads along the joint. Sealing early protects the edges.
Traffic, movement and joints around Romney Street
Romney Street lies roughly 18 miles out from central London. 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. Romney Street 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, while winter salting gets into any joint left open.
For an estate such as Sevenoaks Hospital, 3.3 miles south-west of Romney Street, the joints in ramps, decks and long building elevations all need attention over time. On industrial estates such as West Kingsdown Industrial Estate, 1.7 miles north-east of Romney Street, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.
Romney Street is about 4 miles north-east of Sevenoaks, in Kent. Across the TN15 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Romney Street is one of 931 places we cover in Kent. London is covered too, around 18 miles from Romney Street.
