New build mastic in Shipbourne
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have sealant applied over dusty or wet surfaces and worktop and upstand sealant coming away, we can help.
Around Shipbourne, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
There’s a 12-month guarantee on every job, large or small.

Common questions in Shipbourne
Is Shipbourne within the area you cover?
Yes, Shipbourne is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you do new build mastic in Shipbourne?
Yes. We work across London and the South East, and Shipbourne is part of that. Just call 0345 464 0079 or email us with a few details of the job.
My new home is still under warranty. Should I contact you?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it is not sorted, or keeps failing, get in touch with us.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Is it messy?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you work through snagging lists?
Yes. Photos of each sealant item help us quote. If something is not sealant, we’ll say so.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Aftercare tips
So the new joints stay in good condition:
- Follow the cure time we give you
- Do not wait for the house to settle if water is getting through
- Record problems with dated pictures
- Don’t seal over failed sealant yourself
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.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant and protects the rest of the house.
What the job involves on each surface
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing to keep callbacks down.
Kitchens
As a new house dries, worktops and walls shift a little, which opens gaps along the back. A fresh flexible bead closes them.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.

When to call us in Shipbourne
A new house holds a lot of water from the build, and it dries out over the first couple of years. Drying timber shrinks and pulls joints apart.
Keep an eye out for these signs:
- Beads laid onto grit and dust from the build
- Leaking shower tray seals in a new home
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
Around Shipbourne, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- How hidden problems are handled
- Whether VAT is included
- The length of the guarantee

Why deal with it now?
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. Around Shipbourne, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
