External Mastic in Godmersham
Sealing brickwork movement joints, render, cladding and façade joints for householders, landlords and businesses in Godmersham. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
- Weathered mastic that no longer stretches
DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
External mastic in Godmersham, done properly
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. If you are dealing with leaking joints around cladding and façade panels and moss and dirt in joints with no sealant left, we can put it right, on render & cladding joints, joints between brick and frames and concrete & block alike.
Older homes in small places like Godmersham 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.
All our work comes with a one-year guarantee, wherever you are in Kent.

Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.
How it works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes anything from a few hours to several days, depending on the building from start to finish. Somewhere like Godmersham needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.

When to call us in Godmersham
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Any of these means the joints need attention:
- Joints where the bead has come unstuck
- Movement joints filled with mortar instead of sealant
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
For an older house near a landmark such as Church of St Lawrence, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- How much experience the applicator has
- Which colour the sealant will be
- What product goes in the joint
- How hidden problems are handled
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Act on the first splits you see
- Ask before painting over external sealant
- Avoid pressure-washing directly into sealant joints
- Tell anyone working on the walls about the movement joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges and let water in behind.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established.
Why deal with it now?
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. Around Godmersham, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
