About our new build mastic in Sullington
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 work on plot handovers, bathrooms & en suites and show homes, and common reasons people get in touch are shower seals failing in the first year or two and worktop and upstand sealant coming away.
For a small place like Sullington, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
Big or small, it’s backed by our 12-month guarantee in Sullington and across West Sussex.

Aftercare tips
Aftercare is simple:
- Look at the sealant regularly in the first couple of years
- Get a leaking seal dealt with straight away
- Wait for the cure time before using a resealed shower
- Keep pictures and emails about snagging items
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
When to call us in Sullington
Fresh sealant can be knocked or cut by trades finishing off. If it’s disturbed before curing, the joint can be left weak.

Will it make a mess?

What affects the cost of new build mastic
We quote each job individually. These are the things that affect it:
- Any working-time requirements on site
- The number of rooms or windows
- The size of the job
- Whether there’s mould to deal with
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

To make quoting easier, please include:
- How many joints, rooms or windows are involved
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- What’s wrong with the joints now
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or drop us an email.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
How the visit works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on the number of plots, depending on how much there is to do. Somewhere like Sullington needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- Each joint is cleaned of dust and grit, then primed if required.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
