External & façade joints in South Willesborough, Kent
External mastic in South Willesborough from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Movement joints filled with mortar instead of sealant
- Hard, crazed mastic that has stopped moving
- Rain getting behind render or cladding at a joint
Common problems we fix in South Willesborough
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. 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:
- Rain getting behind render or cladding at a joint
- Failed sealant between panels on a façade
- Joints pointed up with cement by mistake
- Sealant pulling away from one side of the joint
Rented homes near Ashford International station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- How much experience the applicator has
- Which sealant they’ll use, and why
- Whether VAT is included
- When the joint can take water or movement
How we handle external mastic in South Willesborough
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. We work on concrete & block, joints between brick and frames and brickwork movement joints, and the jobs we see most are moss and dirt in joints with no sealant left and weathered mastic that no longer stretches.
Around South Willesborough, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
A one-year guarantee comes as standard, so you are covered after we have gone.

What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. In a smaller place like South Willesborough, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit

Landlord and commercial work in South Willesborough
For anyone letting property in or around South Willesborough, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What external mastic looks like in South Willesborough
With historic houses such as Godinton House (about 3 miles north-west) nearby, there’s older building stock in the area around South Willesborough 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant. Schools such as East Stour Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Questions from South Willesborough
Is South Willesborough within the area you cover?
Yes, South Willesborough is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Ashford International station?
Yes, we work for landlords and letting agents. You can phone 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 take out the old sealant first?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can you quote for more than one area?
Yes. Just list everything you need.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and renew it when it starts to fail.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.

Aftercare tips
To keep the joints looking good and working properly:
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
- Walk round the building once a year and look at the joints
- Keep water from gutters off the wall
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
