Barnsole New Build Mastic
Our applicators work in Barnsole on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a 12-month guarantee.
- Skirting joints opening in the first winter
- Gaps behind new kitchen upstands
- Beads laid onto grit and dust from the build
What happens on the day
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Barnsole, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints

How we handle new build mastic in Barnsole
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. We work on kitchens, plot handovers and skirting & floors, and common reasons people get in touch are beads laid onto grit and dust from the build and gaps opening as the house dries out and settles.
For a small place like Barnsole, the journey and access are planned in advance, and the work itself is the same as on any site.
Big or small, it’s backed by our one-year guarantee.

Why act early in Barnsole
For developers, getting the sealant right first time saves return visits. Snagging visits for failed sealant cost time on every plot, and they’re avoidable with good preparation. Older cottages and farmhouses around Barnsole can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Common questions in Barnsole
Can you do new build mastic in Barnsole?
Yes. Our work covers London and the South East, and Barnsole is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
I let a flat near Adisham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you guarantee your work?
Yes, always. There’s a 12-month guarantee on every job.
Who should fix failed sealant in a new build?
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.
Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so it soon lifts and traps water. We cut the old bead out completely.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Why has my new-build shower seal failed already?
Lots of new homes see sealant crack early, because the house is drying and settling. Rushed application on dusty surfaces makes it worse.
Signs you need new build mastic in Barnsole
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
If you can see any of these, it’s time to have the joints looked at:
- Cracked caulk along new skirting
- Worktop and upstand sealant coming away
- Beads laid onto grit and dust from the build
- Leaking shower tray seals in a new home
If you’ve bought a new home near Adisham station, the sealant around baths, showers and frames is worth checking in the first year or two.
What your quote should include
- How the joint is cleaned and prepared
- Whether you can choose the colour
- Are they insured?
- How long to leave it before use
What the job involves on each surface
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Aftercare tips
Aftercare is simple:
- Put sealant faults on your snagging list early
- Keep pictures and emails about snagging items
- Follow the cure time we give you
- Avoid scourers and strong chemicals on sealant
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and protects the rest of the house.
