External mastic for homes and businesses in Newenden
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we don’t skip that step. If you have movement joints filled with mortar instead of sealant and sealant pulling away from one side of the joint, we can help, whatever the surface.
In a village or hamlet like Newenden, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Joints on those walls need a sealant that moves with the building and stays in place.
There’s a 12-month guarantee on every job, large or small.

What the job involves on each surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. We reseal them with a low-modulus sealant over backing rod in a colour to suit the brick.

What affects the quote in Newenden
Every job gets its own quote. This is what makes a difference:
- The size of the job
- The product the joint needs
- Whether the work is at height
- The number of rooms or windows
Doing several joints on one visit normally makes better use of the time than several 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
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
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.
What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve 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 as small as Newenden, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us if parking is tricky
- Move anything stored near the joints
- Let us know about earlier repairs to the joints

What happens if it’s left?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way. Older cottages and farmhouses around Newenden can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Newenden: your questions answered
Do you cover Newenden for external mastic?
Yes, Newenden is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Is Newenden within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it messy?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
What should I tell you?
A short description and the location. We’ll ask anything else we need to know.
Are you fully insured?
Yes, we are fully insured.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Ground-floor joints are simple; for higher work, tell us about the building and we will confirm what’s needed.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so it does not stand out.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Aftercare tips
Aftercare is simple:
- Look over the joints every year, ideally after winter
- Wash walls gently around the sealant
- Check the sealant is paintable before painting near it
- Keep water from gutters off the wall
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges over time.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
What external mastic looks like in Newenden
Historic houses like Great Dixter (about 1.7 miles south-west) are a reminder that the area around Newenden has older buildings as well as new. In older buildings, 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.
Homes close to Parish Church of St Peter include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. In and around Newenden, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
