External mastic in Wickham St Paul, done properly
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We take the old material out and do it properly. Common call-outs are for movement joints with cracked, split or missing sealant and rain getting behind render or cladding at a joint, across concrete & block, joints between brick and frames and brickwork movement joints.
Around Wickham St Paul, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
Most of a good job is in the preparation, so that is 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. Somewhere like Wickham St Paul needs a little journey planning: 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 checking each joint, agreeing the ones to redo and how we’ll reach them.
- 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.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Mention if the joints have been sealed before
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints

Wickham St Paul buildings and the weather
Historic houses like Hedingham Castle (about 2.7 miles west) are a reminder that the area around Wickham St Paul has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Homes close to Church of All Saints include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Wickham St Paul: your questions answered

Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Why is there a gap in my brick wall?
It’s a deliberate gap that lets the wall expand and contract without cracking. It should be filled with flexible sealant, never mortar.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

What else we do in Wickham St Paul
Surface by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so neither cracks the other.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly if the joint can be cleared.
Why deal with it now?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost, so the problem grows beyond the joint itself. In a small place like Wickham St Paul, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why us?
- White, clear, grey or coloured to suit, where the product allows
- You choose the colour before work begins
- Experience in homes, commercial sites and hotels
- A 12-month guarantee on all work

What we cannot put right
Before booking, it’s worth knowing the limits:
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
- Adding movement joints to masonry that has none
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
Surfaces we seal
- Copings & trims
- Façade panels
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
Common problems we fix in Wickham St Paul
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for these signs:
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
- Panel joints letting water in
- Joints with sealant missing in places
For landlords with property near Sudbury (Suffolk) station, split movement joints are easy to miss on a rental until damp shows inside.

DIY versus a professional finish
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 are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
