How we handle new build mastic in Setley
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on skirting & floors, windows & doors and plot handovers, and common reasons people get in touch are smeared, uneven beads picked up at snagging and sealant applied over dusty or wet surfaces.
Somewhere as small as Setley, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

The process
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. Most jobs take a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Setley, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip 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.
- 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.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Tell us if parking is tricky
- Tell us about any water getting in

Advice
Why it’s worth doing now in Setley
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Where a wall is exposed, as many are in small places like Setley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Signs you need new build mastic in Setley
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
Most people get in touch when they notice one of these:
- Untidy sealant flagged on a snagging list
- Second-fix sealing on new plots
- Beads laid onto grit and dust from the build
- Gaps between new skirting and floors
Around Setley, as everywhere, new build mastic is only as good as the preparation behind it.

Setley: your questions answered
Do you work for landlords with property near Brockenhurst station?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Can you do new build mastic in Setley?
Yes, Setley is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before work begins.
Should I wait before resealing?
Any seal that’s leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we will tell you before work begins. Sealant won’t put right:
- Cracked trays, tiles or worktops
- Structural cracks in walls or ceilings
- Disputes or warranty claims with your builder
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
