Why it’s worth doing now in Horton
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Older cottages and farmhouses around Horton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
Why book with us
- A 12-month guarantee on all work
- Any old sealant cut out fully, not covered over
- A choice of colours where the product allows
- Tidy, careful work

How we handle external mastic in Horton
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on joints between brick and frames, copings & trims and concrete & block, and people most often call us about cracked joints where brick meets render or frames and joints where the bead has come unstuck.
Older homes in small places like Horton may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
There’s a 12-month guarantee on every job.

Outside joints around Horton
With historic houses such as Fitznells Manor (about 1.7 miles east) nearby, there’s older building stock in the area around Horton as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of St Mary the Virgin, an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Chessington South station, outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as St Mary's CofE (Aided) Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How do I get a quote for external mastic in Horton?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or email us and let us know what needs doing and where.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.

That depends on where the joints are. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Rising or penetrating damp from elsewhere in the wall
- Movement that is more than a sealant joint can take
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

How the job changes by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best in all weathers.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
What happens on the day
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Horton, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can

What affects the cost of external mastic
The quote reflects the job in front of us. We look at:
- How much there is to do
- Working hours on commercial sites
- Whether the work is at height
- Whether there’s mould to deal with
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
