Walls and rooflines in High Park Corner
High Park Corner is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
For an older house near a landmark such as The Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant. For site and facilities teams at buildings such as Fingringhoe Church of England Voluntary Aided Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Wivenhoe station, outside joints that have cracked can let damp into a rental, so check them between lets.

How the visit works
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like High Park Corner, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- 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.
How to prepare
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Mention any parking rules near the property

DIY versus a professional finish
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.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Honest limits
Before you book, it’s worth knowing the limits too:
- Walls that need new movement joints cut into them
- Structural movement, which needs a surveyor or engineer
- Cracking across the wall rather than at a joint
If you are not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

Landlords, agents and businesses in High Park Corner
Landlords and letting agents in High Park Corner can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
How to look after the new joints
To keep the joints looking good and working properly:
- Check external joints each spring
- Leave the joints unpainted unless we have said otherwise
- Get split or bare joints resealed while the damage is small
- Keep movement joints as flexible joints, not mortar
Don’t paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.

High Park Corner questions
Can you help a landlord with a rental near Wivenhoe station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Do you cover smaller places like High Park Corner?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
What’s an expansion joint in brickwork?
A vertical gap in a long brick wall is usually a movement joint. It gives the wall room to move, and it should be sealed with a flexible sealant.
Can you match the colour of my brickwork?
We choose a sealant colour to suit the brick, stone or render, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
Do you use backing rod?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Why deal with it now?
Resealing a run of joints in one go is normally better than patching one at a time. Joints of the same age tend to fail together, and access only has to be arranged once. Older cottages and farmhouses around High Park Corner can have timber 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, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
