About our external mastic in Coalhill
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We are often asked to deal with failed seals between different materials and damp patches traced to an open external joint, on joints between brick and frames, copings & trims and façade panels.
Around Coalhill, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.
Big or small, it’s backed by our one-year guarantee in Coalhill and across Essex.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Common problems we fix in Coalhill
Using the wrong sealant is another common reason. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
Any of these means the joints need attention:
- Cracked joints where brick meets render or frames
- Sealant pulling away from one side of the joint
- Hard, crazed mastic that has stopped moving
- Joints pointed up with cement by mistake
Homes close to Church of St Peter include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- When the joint can take water or movement
- What happens if the job turns out different
- The length of the guarantee
- How much experience the applicator has
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. For a village or hamlet like Coalhill, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.

Will you come out to Coalhill?

What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.
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.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
When is the sealant fully cured?
Cure times vary by product and the conditions. We tell you how long to leave it before we go.
Can you do several jobs on one visit?
Yes. More than one area can be quoted together.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Surface by surface
Brickwork movement joints
Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Coalhill buildings and the weather
Historic houses like Danbury Place (about 4.5 miles north) are a reminder that the area around Coalhill has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. The South East is one of 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 let a flat or house near Battlesbridge station, outside joints that have cracked can let damp into a rental, so check them between lets.

What else we do in Coalhill
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
How to look after the new joints
So the new joints stay in good condition:
- Never let anyone fill a movement joint with mortar
- Walk round the building once a year and look at the joints
- Tell anyone working on the walls about the movement joints
- Ask before painting over external sealant
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.
