How the job changes by surface
Car park decks and ramps
Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again flagging broken edges along the way.
Podium joints
Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.
Common questions from Cotman's Ash clients
Is a smaller place like Cotman's Ash outside your area?
Not at all. Cotman's Ash is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Chaucer Business Park, near Cotman's Ash?
Yes. Our area takes in Cotman's Ash and its surroundings, with estates and business parks such as Chaucer Business Park included. Photos and a short description are enough for a first look.
Can you quote from photos?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we’ll arrange a visit before quoting.
What guarantee do you give on joint sealing?
The workmanship is guaranteed for 12 months from sign-off, and we are fully insured for public liability. Keeping joints clear of debris helps them last.
How long does movement joint sealing take?
Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Timings are set out in the quote, including any phasing.
What’s the difference between an expansion joint and a movement joint?
It’s a deliberate gap that lets the structure move without cracking. Expansion joint is a name often used for the same thing and both need a flexible seal.
How do you choose the sealant?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
For managing agents and facilities managers
We work for building owners and managing agents on everything from one building to a spread of sites around Cotman's Ash. Several sites can go on one quote, so there’s one set of paperwork to deal with.

How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. If others near Cotman's Ash need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
- Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- Each joint is inspected and handed over with our 12-month guarantee.

Advice
Why deal with it now?
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. Tell us what has to stay open and we will plan around it. One visit to deal with every failing joint makes more sense than several trips to a place like Cotman's Ash. Send photographs of each area and we’ll quote for the lot.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Expansion joint sealing around Cotman's Ash: what changes locally
Less than 3 miles from Cotman's Ash there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Cotman's Ash sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.
Large sites such as Sevenoaks Hospital (2.8 miles south-west of Cotman's Ash) have car parks, service roads and long elevations with movement joints in brick and panels. Across sites such as West Kingsdown Industrial Estate, 1.9 miles to the north-east of Cotman's Ash, floor and movement joints can be sealed in phases so units keep working. For a school such as Kemsing Primary School, playground and building joints can be done in the holidays.

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
