External mastic in Red Hill, done properly
On houses, flats and commercial buildings across Red Hill, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. Typical jobs include brick movement joints where the sealant has split and failed sealant between panels on a façade, across façade panels, joints between brick and frames and copings & trims.
External sealant needs dry, clean surfaces, so work around Red Hill is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
We stand behind the work with a one-year guarantee.

Honest limits
New sealant cannot fix everything, and we’ll tell you before we start. It won’t solve:
- Rising or penetrating damp from elsewhere in the wall
- Structural movement, which needs a surveyor or engineer
- Adding movement joints to masonry that has none

FAQs for Red Hill
Do you work for landlords with property near Wateringbury station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Is Red Hill within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Do you use backing rod?
We fit closed-cell backing rod wherever the joint depth needs controlling. It controls the depth and stops the sealant bonding to the back.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you work at height?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
What information do you need?
Let us know what needs doing and where, plus photos if you have them. If we need more, we will ask.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
How we quote for external mastic
The price is agreed before any work begins. It takes into account:
- The type of sealant required
- How many areas need sealing
- How easy the joints are to reach
- How much there is to do
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- If it’s domestic, commercial or a hotel
- Where the job is, and your postcode
- The problem you’ve noticed
- How we’d reach the joints
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we’ll explain what’s involved and send you a clear quote.
Red Hill buildings and the weather
With historic houses such as Old Soar Manor (about 4.8 miles west) nearby, there’s older building stock in the area around Red Hill as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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.
Homes close to Church of St Peter and St Paul include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move. If you look after a building such as Wateringbury Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Letting a property close to Wateringbury station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Around Red Hill
Around Red Hill, our work takes us to homes and buildings near The Malling School and North Pole pub, among other places.

Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. Around Red Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

How the visit works
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Red Hill, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

What the job involves on each surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Landlord and commercial work in Red Hill
We also work for property managers and facilities teams in Red Hill and across Kent. Several sites can go on one quote, and we’re fully insured.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Fix overflowing gutters above sealed joints
- Don’t let climbing plants root in the sealant
- Have failed joints looked at early
- Tell anyone working on the walls about the movement joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
