External & façade joints in Baldslow, East Sussex
Movement joints in Baldslow need attention? We cut out the old, prepare the joints and apply the right sealant.
- Failed seals between different materials
- Panel joints letting water in
- Joints with sealant missing in places
How we handle external mastic in Baldslow
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what access is needed. We work on façade panels, brickwork movement joints and concrete & block, and people most often call us about weathered mastic that no longer stretches and water getting into walls through failed joints.
Outside joints can only be sealed when they’re dry, so work in Baldslow is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What the job involves on each surface
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.

What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. Where a wall is exposed, as many are in small places like Baldslow, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

- Cracked brickwork or render that needs a builder or plasterer
- Loose or hollow render, which needs re-rendering
- Walls that need new movement joints cut into them

How we quote for external mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Working hours on commercial sites
- The type of sealant required
- The old material and how stubborn it is
- Access and height
What you pay reflects the work, not a rough estimate. That is why we ask about the job first.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- The type of property
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
What we do, step by step
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere like Baldslow needs a little journey planning: 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 look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

Advice
Looking after it afterwards
Looking after new joints is easy:
- Deal with leaking gutters that soak the joints below
- Keep soil, plants and ivy away from the joints
- Make sure movement joints are not pointed over
- Walk round the building once a year and look at the joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
What external mastic looks like in Baldslow
Baldslow is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Durhamford Manor (about 3.8 miles north-west) nearby, there’s older building stock in the area around Baldslow as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Managing a site like Ark Helenswood Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For landlords with property near Ore station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to Church of St John the Evangelist include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.

Baldslow: your questions answered
Does living near the coast affect external mastic in Baldslow?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Do you work for landlords with property near Ore station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover Baldslow?
Yes, we do. Our applicators work in Baldslow, and the service is the same as everywhere else.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. The sealant is chosen to bond to both sides with primer where required.
Can I add another job to the visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Can new sealant go over the old?
No. The old sealant always comes out first.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
