External mastic in Lindsell
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it and we use one wherever it does. We work on copings & trims, render & cladding joints and concrete & block, and common reasons people get in touch are joints pointed up with cement by mistake and joints with sealant missing in places.
Older homes in small places like Lindsell may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Our work is backed for twelve months, in Lindsell and everywhere else we cover.

What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Lindsell, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Advice
Lindsell: your questions answered
Is there a guarantee on external mastic in Lindsell?
Every job comes with our 12-month guarantee, wherever it is. We’re also fully insured and ARBOMaster approved.
Do you cover Lindsell for external mastic?
Yes, Lindsell is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
How long does external mastic take?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. We’ll confirm how long when we quote.
How the job changes by surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Common problems we fix in Lindsell
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Most people get in touch after spotting one of these:
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
- Plants rooting in failed movement joints
- Movement joints filled with mortar instead of sealant
If you live in an older home near Church of St Mary the Virgin, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Comparing quotes
- How the joint is cleaned and prepared
- What happens if they find a problem under the old sealant
- Is the old sealant removed completely?
- Is VAT in the price?
Keeping the joints in good condition
So the new joints stay in good condition:
- Never let anyone fill a movement joint with mortar
- Wash walls gently around the sealant
- Show decorators and builders where the movement joints are
- Check the sealant is paintable before painting near it
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
What else we do in Lindsell
Can I do it myself?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
What external mastic looks like in Lindsell
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Horham Hall (about 3.6 miles north-west) are a reminder that the area around Lindsell has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
Managing a site like Putteridge High School? Then larger buildings have long runs of movement joint that eventually need resealing.
