External mastic for homes and businesses in Tatsfield
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a matching colour. Typical jobs include damp patches traced to an open external joint and cracked joints where brick meets render or frames, on joints between brick and frames, render & cladding joints and façade panels.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Tatsfield, tell us how high the joints are and how to reach the back of the building.
Each job carries a 12-month guarantee, large or small.

What sealant work can’t fix
It helps to know what we cannot do too:
- Walls that need new movement joints cut into them
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.
What we seal
- Façade panels
- Render & cladding joints

- Concrete & block
Common problems we fix in Tatsfield
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
If you can see any of these, it’s time to have the joints looked at:
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
- Leaking joints around cladding and façade panels
- Joints pointed up with cement by mistake
For an older house near a landmark such as Church of St Mary the Virgin, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Before you book anyone
- How hidden problems are handled
- The length of the guarantee
- How the joint is cleaned and prepared
- Who does the work, and how experienced they are

Is it OK to fill a movement joint with cement?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose. A flexible sealant is the right fill.
How often do external joints need resealing?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and renew it when it starts to fail.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.
Is the work guaranteed?
Yes. Each job is guaranteed for twelve months.
Is it messy?
We keep the work tidy. We protect what’s around the joints.

Walls and rooflines in Tatsfield
In terraces and conversions, gutters and walls are often shared with the neighbours, so check who is responsible for the outside before booking. With historic houses such as Titsey Place (about 1.4 miles south-west) nearby, there’s older building stock in the area around Tatsfield 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.
For site and facilities teams at buildings such as Charles Darwin School, its movement joints, gutters and trims need looking after like any other building’s. As a London address, Tatsfield can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

What happens if it’s left?
Water gets in through a failed movement joint, behind render and cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
The process
We work through the job in order: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on the building, and the area is left clean. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Tatsfield. A visitor permit or a nearby bay makes the visit run more smoothly.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Clear the area around the work
