About our external mastic in Priestwood
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the joint does not stand out. We work on brickwork movement joints, copings & trims and render & cladding joints, and the jobs we see most are hard, crazed mastic that has stopped moving and weeds or debris growing in open joints.
Around Priestwood, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.
Big or small, you get the same 12-month guarantee.

Common problems we fix in Priestwood
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Keep an eye out for any of the following:
- Joints with sealant missing in places
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
Homes close to Church of Our Lady of the Meadow include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How it works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Priestwood, the journey is planned in advance: 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 inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit

What external mastic looks like in Priestwood
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Cobham College (about 2.6 miles north-east) are a reminder that the area around Priestwood 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.
If you look after a building such as Meopham School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Sole Street station, split movement joints are easy to miss on a rental until damp shows inside.

Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Damp that isn’t coming from the joint
- Cutting new joints into brickwork, which is building work rather than sealant work
- Failed render or damaged cladding panels

Priestwood: your questions answered
Can you do external mastic in Priestwood?
Yes, Priestwood is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will it make a mess?

How much does external mastic cost in Priestwood?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall. If it has already been filled, we can usually cut it out and reseal it.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Why is there a gap in my brick wall?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It should be filled with flexible sealant, never mortar.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Different surfaces, different methods
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.
Render joints
Render is weaker at the surface than brick, so a sealant that stretches easily protects the edges. We prime where the product needs it.
