What new build mastic looks like in Icklesham
Icklesham is within about 3 miles of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
In and around Icklesham, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic for homes and businesses in Icklesham
We never seal over a failed new-build bead. New silicone will not bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We’re often asked to deal with new-build shower sealant that has already split and untidy sealant flagged on a snagging list, across plot handovers, windows & doors and skirting & floors.
In a village or hamlet like Icklesham, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.

Common problems we fix in Icklesham
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
The problems people generally mention when they call include:
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
- Internal frame sealant that has split
- Messy sealant that spoils new finishes
For new homes near Winchelsea station, it’s worth checking the sealant early, while snags are still fresh.

Icklesham: your questions answered
Is Icklesham 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.
Can you help a landlord with a rental near Winchelsea station?
Yes, we work for landlords and agents. Just call 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
How long does new build mastic take?
Typically it takes anything from a few hours to several days, depending on the number of plots. Bigger jobs take longer, and we will say how long yours will take.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we will explain our choice.
Should I go to my builder first?
Start with your builder while their snagging or warranty period runs. After that, or if their repair keeps failing, we can do it.
Do you guarantee your work?
Yes. All our work carries a one-year guarantee.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator.
How we quote for new build mastic
Jobs vary more than people expect. The main factors:
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
- How many rooms, windows or areas are involved
- The product the joint needs
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- How many joints, rooms or windows are involved
- If someone has resealed it before
- A few photos by email, if you can
- Access, such as stairs, a lift or height
Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job, and we’ll take it from there.
Why act early in Icklesham
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote to plan around. Older cottages and farmhouses around Icklesham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Surface by surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
