About our new build mastic in Wisborough Green
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on windows & doors, bathrooms & en suites and show homes, and people most often call us about cracked caulk along new skirting and plot mastic for developers ahead of handover.
In a village or hamlet like Wisborough Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Every job is covered by our one-year guarantee, wherever you are in West Sussex.

Related advice
Why act early in Wisborough Green
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Resealing promptly protects the new finishes around it. Around Wisborough Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Kitchens
Beside the sink, the joint takes water every day. A kitchen sealant goes in there suited to the job.
When to call us in Wisborough Green
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Both fail early.
The problems people generally mention when they call include:
- Plot mastic for developers ahead of handover
- Sealant applied over dusty or wet surfaces
- Frame joints opening as the plaster dries
- Skirting joints opening in the first winter
For new homes near Billingshurst station, it’s worth checking the sealant early, while snags are still fresh.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Your questions about new build mastic in Wisborough Green
Do you cover smaller places like Wisborough Green?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is Wisborough Green in your area for new build mastic?
Yes. We work across London and the South East, and Wisborough Green is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
Do you guarantee your work?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before any work starts.
Do you work through snagging lists?
Yes. Send it with photos and we’ll quote for the sealant items. If something is not sealant, we will say so.
Should I wait before resealing?
Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
When something else is needed
We won’t take on work that will not last, so here’s what sealant can’t put right:
- Disputes or warranty claims with your builder
- Cracked trays, tiles or worktops
- Cracking that points to a structural problem
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think before booking.
