How we handle new build mastic in Netley Marsh
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that’s what rushed new-build sealant usually lacks. We work on skirting & floors, bathrooms & en suites and kitchens, and common reasons people get in touch are joints pulling apart as timber shrinks and cracked caulk along new skirting.
Somewhere as small as Netley Marsh, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

What new build mastic looks like in Netley Marsh
Netley Marsh is close to the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around Netley Marsh, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Ashurst New Forest station, it’s worth checking the sealant early, while snags are still fresh.

How the visit works
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours in a single home. Somewhere as small as Netley Marsh, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
- Keep children and pets away from the work area

Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. In a small place like Netley Marsh, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts.
Why choose Mr Mastic in Netley Marsh

Different surfaces, different methods
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. We cut it out and reseal neatly.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly.

Your questions about new build mastic in Netley Marsh
I let a flat near Ashurst New Forest station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Netley Marsh?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is it normal for sealant to crack in a new home?
New homes dry out and move in their first couple of years, and sealant is often rushed onto dusty, unprimed surfaces. Both lead to early failure.
Will the old sealant be removed?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator.
What does new build mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, phone 0345 464 0079 or drop us an email with a short description of the job.
Can you work from my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
