New build mastic in Boarhunt
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 using the right product for each joint. If you’re dealing with new-build shower sealant that has already split and smeared, uneven beads picked up at snagging, we can put it right, whatever the surface.
In a village or hamlet like Boarhunt, 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 isn’t right with it in that time, tell us and we will put it right.

How much does new build mastic cost in Boarhunt?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Can you reseal over the builder’s sealant?
No. The old sealant is cut out fully, the joint cleaned and primed where needed, and a new bead applied.
Where do you work from?
We work from Crawley. We cover Boarhunt and the rest of Hampshire.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Do you guarantee your work?
Yes. Each job is guaranteed for twelve months.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
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.
When something else is needed
In fairness, there are a few things sealant won’t fix:
- Plumbing faults behind the sealant
- Broken tiles or a split tray
- A tray or bath that isn’t properly supported, until it’s fixed
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Avoid scourers and strong chemicals on sealant
- Do not seal over failed sealant yourself
- Raise failed sealant with the developer while you are covered
- Keep water off fresh sealant until it has cured
Don’t stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
What new build mastic looks like in Boarhunt
Boarhunt is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.
If you’ve bought a new home near Portchester station, the sealant around baths, showers and frames is worth checking in the first year or two. Around Boarhunt, as everywhere, new build mastic is only as good as the preparation behind it.
