External mastic for homes and businesses in Telscombe Cliffs
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant. If you are dealing with brick movement joints where the sealant has split and gaps where render, brick and frames meet, we can put it right.
Around Telscombe Cliffs, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Every job comes with our one-year guarantee.

Common questions in Telscombe Cliffs
Can you help a landlord with a rental near Newhaven Town station?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.
Is external mastic in a coastal place like Telscombe Cliffs any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Can I add another job to the visit?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Will the new joint stand out?
The sealant colour is picked to suit the wall, so the joint sits quietly in the wall. There’s a wide choice of exterior colours.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
The process
On the day, we look over the joints with you first. We protect the surfaces around the joints before we start. Most jobs take a few hours for a handful of joints, longer for a whole elevation. For a job in Telscombe Cliffs, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

What affects the quote in Telscombe Cliffs
Some jobs are bigger than they look, and some smaller. What affects the quote:
- How many areas need sealing
- How easy the joints are to reach
- Any mould that needs treating
- The old material and how stubborn it is
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- How we’d reach the joints
- Where the property is
- Whether it has been sealed before
- A few photos by email, if you can

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Deal with leaking gutters that soak the joints below
- Check external joints each spring
- Clear growth from the base of walls and joints
- Ask before painting over external sealant
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Resealing it early helps prevent that.

What external mastic looks like in Telscombe Cliffs
Telscombe Cliffs is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. 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.
Schools such as Telscombe Cliffs Community Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Rented homes near Newhaven Town station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

What we’re called out for in Telscombe Cliffs
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
Signs it’s time to call us include:
- Joints pointed up with cement by mistake
- Gaps where render, brick and frames meet
- Brick movement joints where the sealant has split
- Moss and dirt in joints with no sealant left
Homes close to Ascension Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before booking
- Whether VAT is included
- How the colour is chosen
- How the joint is cleaned and prepared
- What insurance they hold
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, 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.
