External Mastic in Cousley Wood
Movement joints in Cousley Wood need attention? We remove the old material, prepare the joints and seal them properly.
- Failed sealant between panels on a façade
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
Honest limits
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Structural movement, which needs a surveyor or engineer
- Failed render or damaged cladding panels
- Cracks in the bricks or render themselves, away from the joints
If in doubt, phone 0345 464 0079 or email us and we’ll say what we think.
Surfaces we seal
- Façade panels
- Joints between brick and frames
- Concrete & block
- Brickwork movement joints
- Copings & trims
- Render & cladding joints
External mastic in Cousley Wood
For buildings in Cousley Wood, we reseal external joints of all kinds, from brick movement joints to cladding panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on copings & trims, brickwork movement joints and façade panels, and people most often call us about leaking joints around cladding and façade panels and cracked joints where brick meets render or frames.
In a village or hamlet like Cousley Wood, older cottages and farm buildings often stand in the open, 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 of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes anything from a few hours to several days, depending on the building, depending on the amount of work. For a village or hamlet like Cousley Wood, 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.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Mention any tricky access
- For business premises, tell us about site rules or sign-in

How we quote for external mastic
Jobs vary more than people expect. What affects the quote:
- Any working-time requirements on site

Landlords, agents and businesses in Cousley Wood
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.
How the job changes by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out and helps it last.

When to call us in Cousley Wood
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
Keep an eye out for these signs:
- Weathered mastic that no longer stretches
- Sealant pulling away from one side of the joint
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
Homes close to Rehoboth Chapel include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Cousley Wood: your questions answered
Can you help a landlord with a rental near Wadhurst station?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear quote.
Is Cousley Wood in your area for external mastic?
Yes. We work across London and the South East, and Cousley Wood is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
How long does external mastic take?
It depends on the size of the job, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.
Why do you put foam in the joint first?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we will tell you the cure time.
Where is Mr Mastic based?
We are based in Crawley, and we work across South East England, London and Scotland.
Can I do it myself?
That depends on the joint. 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.
Are you fully insured?
Yes. We are fully insured.
Walls and rooflines in Cousley Wood
Historic houses like Wadhurst Castle (about 1.6 miles south-west) are a reminder that the area around Cousley Wood has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Managing a site like Uplands Community College? Then its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Wadhurst station, split movement joints are easy to miss on a rental until damp shows inside.

Why deal with it now?
Resealing a run of joints in one go is normally better than patching one at a time. They’ve weathered the same way and it means sorting access once. Where a wall is exposed, as many are in small places like Cousley Wood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.
