Wateringbury External Mastic
External mastic across Wateringbury and nearby, with every bit of old sealant taken out first and a 12-month guarantee.
- Movement joints with cracked, split or missing sealant
- Weathered mastic that no longer stretches
- Moss and dirt in joints with no sealant left
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Act on the first splits you see
- Don’t let climbing plants root in the sealant
- Leave the joints unpainted unless we have said otherwise
- Fix overflowing gutters above sealed joints
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
External mastic in Wateringbury
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. We’re often asked to deal with weeds or debris growing in open joints and hard, crazed mastic that has stopped moving, across copings & trims, joints between brick and frames and concrete & block.
External sealant needs dry, clean surfaces, so work around Wateringbury is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What external mastic looks like in Wateringbury
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 Old Soar Manor (about 4.4 miles west) are a reminder that the area around Wateringbury 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.
Homes close to Church of St John the Baptist include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. Letting a property close to Wateringbury station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Wateringbury Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

What affects the quote in Wateringbury
There’s no set price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- Which sealant suits the joint
- The old material and how stubborn it is
- When we can work, for business premises
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll send you a clear quote for the lot.
What to tell us for a quote
When you call or email, it’s useful to know:
- The address or postcode of the job
- Roughly how big the job is
- Any access issues, like height or stairs
- The problem you’ve noticed
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. When it suits you, phone 0345 464 0079 or email us.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

Why it’s worth doing now in Wateringbury
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. A stiffer product can damage the joint edge as it fails. Around Wateringbury, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
What you get with us
- Old sealant always removed completely
- Sanitary silicone with an anti-fungal additive in wet areas

Wateringbury: your questions answered
Do you cover Wateringbury for external mastic?
Yes. Our work covers London and the South East, and Wateringbury is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
I let a flat near Wateringbury station. Can you help?
Yes, we work for landlords and agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
How do I get a quote for external mastic in Wateringbury?
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. We agree the price before any work begins.
How do you reach high-level joints?
It depends on the height and the site. Low-level joints are straightforward; for higher work, tell us about the building and we will confirm what’s needed.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so the joint between them must be flexible. We choose one that suits both surfaces.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it does not stand out.
Are you fully insured?
Yes. Mr Mastic is fully insured.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll give you a quote.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
What the job involves on each surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
How it works
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Wateringbury, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on
