How we handle external mastic in Berwick
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. Common call-outs are for hard, crazed mastic that has stopped moving and water getting into walls through failed joints, on copings & trims, façade panels and joints between brick and frames.
Somewhere as small as Berwick, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. 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.

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes anything from a few hours to several days, depending on the building. Somewhere like Berwick needs a little journey planning: 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 we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- 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
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints

DIY sealant or a professional job?
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.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Why deal with it now?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way. Older cottages and farmhouses around Berwick can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

External mastic in Berwick: local notes
Berwick 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. With historic houses such as Westenhanger Castle (about 0.9 miles north) nearby, there’s older building stock in the area around Berwick as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Lympne Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you let a flat or house near Westenhanger station, outside joints that have cracked can let damp into a rental, so check them between lets.

How we quote for external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- The old material and how stubborn it is
- Which sealant suits the joint
- Whether there’s mould to deal with
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
When you call or email, it’s useful to know:
- If someone has resealed it before
- The address or postcode of the job
- How many joints, rooms or windows are involved
- The problem you’ve noticed
For a quote, ring 0345 464 0079 or email us with the location and a short description of the problem. We will send you a clear quote before any work starts.
When to call us in Berwick
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, so it pulls away from the edges.
The problems people usually mention when they call are:
- Plants rooting in failed movement joints
- Damp patches traced to an open external joint
- Failed sealant between panels on a façade
- Joints with sealant missing in places
If you live in an older home near Church of St Stephen, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before booking
- What product goes in the joint
- Is VAT in the price?
- What preparation is included
- How long to leave it before use
Berwick questions
Is external mastic in a coastal place like Berwick any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you help a landlord with a rental near Westenhanger station?
Yes, we work for landlords and letting agents. 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 the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
What information do you need?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or email us.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
How long does external mastic last?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. Check them each year and reseal when they split or harden. Every job carries our one-year guarantee.
