Problem with your new-build sealant joints in Telscombe Cliffs? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

New build mastic in Telscombe Cliffs, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. Typical jobs include beads laid onto grit and dust from the build and leaking shower tray seals in a new home, on skirting & floors, show homes and plot handovers.
Where new homes go up in smaller places like Telscombe Cliffs, it’s often a small development or a single plot. Each still needs its sealant and floor joints finished properly from day one.
Big or small, it’s backed by our one-year guarantee.

How it works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work starts. The work usually takes anything from a few hours to several days, depending on the number of plots. In a smaller place like Telscombe Cliffs, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises

Telscombe Cliffs: your questions answered
I let a flat near Newhaven Town station. Can you help?
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’ll give you a clear price.
Can you do new build mastic in Telscombe Cliffs?
Yes, Telscombe Cliffs is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
What should I tell you?
A short description and the location, with pictures by email if possible. We will ask anything else we need to know.
What colour sealant will you use?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job, large or small.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. We cut the old bead out completely.
When something else is needed
To be straight with you, some problems need a different trade:
- Plumbing faults behind the sealant
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Avoid running a DIY bead over the old one
- Keep water off fresh sealant until it has cured
- Wipe joints with warm soapy water
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you.
Joints and finishes in Telscombe Cliffs homes
Telscombe Cliffs is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. 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.
In and around Telscombe Cliffs, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Newhaven Town station, it’s worth checking the sealant early, while snags are still fresh.
