New build mastic in Stanswood
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 plot handovers, skirting & floors and kitchens, and people most often call us about cracked sealant around new window and door frames and sealant applied over dusty or wet surfaces.
In a village or hamlet like Stanswood, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

Stanswood questions
I let a flat near Hamble station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Do you cover Stanswood for new build mastic?
Yes. Our work covers London and the South East, and Stanswood is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
How long does new build mastic take?
Most jobs take a few hours for most snagging lists, longer for a run of plots, including the preparation. Your quote will say how long we expect yours to take.
Why does sealant fail so quickly in new builds?
There are generally two causes: the house moving as it dries, and sealant that never bonded properly. Cutting it out and resealing properly fixes both.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Do you work for developers?
Yes. Plot mastic and second-fix sealing for developers is part of our work. Send us the plot schedule and we will quote.
Can you reseal over the builder’s sealant?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Landlord and commercial work in Stanswood
We work for landlords and agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order.
Housing providers, facilities teams and property managers book us too in Stanswood and across Hampshire. We can quote a run of properties together, and we’re fully insured.
Looking after it afterwards
To keep the joints looking good and working properly:
- Ventilate bathrooms well, especially in the first year
- Keep water off fresh sealant until it has cured
- Avoid running a DIY bead over the old one
- Wipe joints with warm soapy water
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
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.
What happens on the day
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours in a single home. For a village or hamlet like Stanswood, 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 go through the snagging list or plot schedule and agree the joints to do.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Mention any tricky access
- Let us know about parking restrictions
- Clear the area around the work

Related advice
Different surfaces, different methods
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed.
Honest limits
In fairness, some problems need a different trade:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Do you need new build mastic in Stanswood?
Sealant applied onto damp surfaces doesn’t bond well. Site programmes do not always leave time for joints to dry first.
Signs it’s time to call us include:
- Sealant work across a run of new homes
- New-build shower sealant that has already split
- Cracked caulk along new skirting
- Beads laid onto grit and dust from the build
For new homes near Hamble station, it’s worth checking the sealant early, while snags are still fresh.

DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
New build mastic around Stanswood
Stanswood 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Stanswood, as everywhere, new build mastic is only as good as the preparation behind it.
