External mastic for homes and businesses in Crowhurst
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We’re often asked to deal with joints with sealant missing in places and failed sealant between panels on a façade, across render & cladding joints, copings & trims and concrete & block.
Somewhere as small as Crowhurst, homes and farm buildings often face open ground, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
All our work comes with our 12-month guarantee, wherever you are in East Sussex.

Crowhurst: your questions answered
Is Crowhurst within the area you cover?
Yes, Crowhurst is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
I let a flat near Crowhurst station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
How much does external mastic cost in Crowhurst?
Size, access and the old material all affect the cost. Ask us for a quote.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages.
Will the new joint stand out?
The sealant colour is picked to suit the wall. There’s a wide choice of exterior colours.
Common problems we fix in Crowhurst
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
If you can see any of these, it’s time to have the joints looked at:
- Cracked joints where brick meets render or frames
- Weathered mastic that no longer stretches
- Weeds or debris growing in open joints
- Rigid filler in a joint that should flex
For landlords with property near Crowhurst station, outside joints that have cracked can let damp into a rental, so check them between lets.

Surface by surface
Brickwork movement joints
Brick movement joints are often mistaken for a missing mortar line. If that is happened, we rake it out and reseal it properly where it can be done safely.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.
Landlord and commercial work in Crowhurst
Landlords and letting agents in Crowhurst can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
How to look after the new joints
After the cure time, these simple habits help:
- Get split or bare joints resealed while the damage is small
- Clear growth from the base of walls and joints
- Make sure movement joints are not pointed over
- Check the sealant is paintable before painting near it
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Crowhurst buildings and the weather
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Durhamford Manor (about 3.8 miles north) nearby, there’s older building stock in the area around Crowhurst as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
If you live in an older home near The Parish Church of St George, older walls, gutters and the joints where extensions meet them need a flexible sealant. Managing a site like Crowhurst CofE Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How it works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on the building, including the tidy-up. Somewhere like Crowhurst needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip 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.
- The joint faces are cleaned and primed where the sealant needs 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
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
- Tell us about any water getting in
