About our new build mastic in New Milton
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, bathrooms & en suites and show homes, and the jobs we see most are gaps between new skirting and floors and gaps opening as the house dries out and settles.
If you’ve bought a new home in or near New Milton, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.
There’s a 12-month guarantee on every job, whatever its size.

New homes and floors in New Milton
New Milton is close to the coast. New homes near the sea put their outside mastic to work from day one, 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.
For new homes near New Milton station, it’s worth checking the sealant early, while snags are still fresh.

What else we do in New Milton
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Clean sealant with mild detergent, not abrasives
- Put sealant faults on your snagging list early
- Do not wait for the house to settle if water is getting through
- Watch for new gaps as the house dries out
Don’t stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Catching it early keeps the fix to the sealant.
What we can’t put right
Sealant isn’t the answer to every problem, and we’ll tell you before we start. Sealant will not put right:
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
- Broken tiles or a split tray
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
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.
Surface by surface
Plot handovers
Developers can send the plot schedule and specification and we’ll quote. Sealant work across the plot is covered.
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
For landlords and businesses
If you manage several properties in or around New Milton, several properties can be quoted together. Send us the addresses and the work at each, and pictures by email help.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Common problems we fix in New Milton
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Most people get in touch when they notice one of these:
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
- Cracks appearing as a new home settles
In and around New Milton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- Is the old sealant removed completely?
- Whether they’re fully insured
- How the colour is chosen
- Who does the work, and how experienced they are
The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots. Parking around New Milton is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked for movement before any work starts.
- 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.
- We check every joint and leave you with the cure times.
How to prepare
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
