Why act early in Rodmersham Green
Sealing over the top of old mastic doesn’t hold for long. The new layer cannot bond properly to old, weathered material, so we always take the old sealant out. Older cottages and farmhouses around Rodmersham Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

External mastic in Rodmersham Green
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We are often asked to deal with plants rooting in failed movement joints and failed sealant between panels on a façade, across brickwork movement joints, render & cladding joints and façade panels.
Older homes in small places like Rodmersham Green may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
Whatever the size of the job, you get the same one-year guarantee.

The process
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Rodmersham Green, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

External mastic in Rodmersham Green: local notes
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Rodmersham School? Then larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Sittingbourne station? Then outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to Church of St Nicholas include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Rodmersham Green: your questions answered
I let a flat near Sittingbourne station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Rodmersham Green?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you reach joints on upper floors?
Each building is different. Send us pictures and a rough idea of the height and we’ll confirm how they can be reached safely.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before any work starts.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you insured?
Yes, we’re fully insured.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Leave the joints unpainted unless we’ve said otherwise
- Wash walls gently around the sealant
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
Landlords, agents and businesses in Rodmersham Green
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What sealant work can’t fix
We won’t take on work that will not last, so these are the limits:
- Damp that is not coming from the joint
- Movement that is more than a sealant joint can take
- Walls that need new movement joints cut into them
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.
