How the visit works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the building. A visit to West Blatchington is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

External mastic for homes and businesses in West Blatchington
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on façade panels, copings & trims and concrete & block, and people most often call us about sealant that has lost its bond to the brick or render and water getting into walls through failed joints.
In a smaller place like West Blatchington, some homes face open ground, and walls and rooflines facing the weather take the worst of it. Joints on those sides are normally the first to go.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

External mastic in West Blatchington: local notes
West Blatchington is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Preston Manor & Gardens (about 1.3 miles east) are a reminder that the area around West Blatchington has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For site and facilities teams at buildings such as Aldrington CofE Primary School, larger buildings have long runs of movement joint that eventually need resealing. In the older streets around St Peter's Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. Rented homes near Aldrington station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Clear growth from the base of walls and joints
- Act on the first splits you see
- Tell anyone working on the walls about the movement joints
- Keep high-pressure jets off the joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.

FAQs for West Blatchington
Can you help a landlord with a rental near Aldrington station?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Will you come out to West Blatchington?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do you work at height?
It depends on the building. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
How long should I leave it?
Cure times vary by product and the temperature. We tell you how long to leave it before we go.
Can you do several jobs on one visit?
Yes. More than one area can go on one quote.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
What do you need from me for a quote?
A short description and the location. We will ask anything else we need to know.
What we cannot put right
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Render that is blown, hollow or coming away
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
Surfaces we seal
- Joints between brick and frames
- Brickwork movement joints
- Concrete & block
- Copings & trims
- Façade panels
- Render & cladding joints
Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. In an older home around West Blatchington, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How the job changes by surface
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
