External mastic in Peasmarsh, done properly
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on copings & trims, render & cladding joints and brickwork movement joints, and common reasons people get in touch are rigid filler in a joint that should flex and gaps where render, brick and frames meet.
Somewhere as small as Peasmarsh, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Our work is backed for twelve months, in Peasmarsh and everywhere else we cover.

Signs you need external mastic in Peasmarsh
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
These are the problems we are asked about most:
- Leaking joints around cladding and façade panels
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Water getting into walls through failed joints
Letting a property close to Rye station? Then split movement joints are easy to miss on a rental until damp shows inside.

What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Working hours on commercial sites
- Any mould that needs treating
- Whether the work is at height
- The number and length of the joints
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Peasmarsh questions
Do you work for landlords with property near Rye station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover Peasmarsh for external mastic?
Yes. We work across London and the South East, and Peasmarsh is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job.
Will the new joint stand out?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before any work starts.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can I do it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Have failed joints looked at early
- Keep water from gutters off the wall
- Walk round the building once a year and look at the joints
- Clear growth from the base of walls and joints
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
What we do, step by step
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Peasmarsh, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints

DIY sealant or a professional job?
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 does not work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

External mastic in Peasmarsh: local notes
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Lamb House (about 2.5 miles south-east) nearby, there’s older building stock in the area around Peasmarsh as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Schools such as Peasmarsh Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. In the older streets around The Parish Church of St Peter and St Paul, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Honest limits
To be straight with you, there are a few things sealant won’t fix:
- Structural movement, which needs a surveyor or engineer
- Render that’s blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
