About our new build mastic in Roundbush
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. If you have cracked caulk along new skirting and messy sealant that spoils new finishes, we can help, on plot handovers, kitchens and bathrooms & en suites alike.
Around Roundbush, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

New build mastic around Roundbush
Roundbush is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. 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 Roundbush, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Use the extractor fan every time you shower
- Don’t seal over failed sealant yourself
- Clean sealant with mild detergent, not abrasives
- Keep pictures and emails about snagging items
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
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.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Leaking fittings rather than failed sealant
- Cracking that points to a structural problem
- Damaged fittings that need replacing
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.

What we do, step by step
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere like Roundbush needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height
- Plan for the work area to be out of bounds to pets and children

Advice
What we are called out for in Roundbush
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry first.
These are the problems we’re asked about most:
- Messy sealant that spoils new finishes
- Frame joints opening as the plaster dries
- Kitchen sealant that has pulled off the wall
- Plot mastic for developers ahead of handover
If you’ve bought a new home near North Fambridge station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why does sealant fail so quickly in new builds?
It’s common, and there are generally two reasons: movement as the house dries and settles, and sealant laid onto dust without primer. Cutting it out and resealing properly fixes both.
Surface by surface
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one that suits the frame.
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
For landlords and businesses
We also work for property managers and facilities teams. We can quote a run of properties together.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
