Michelmersh New Build Mastic
Our applicators work in Michelmersh on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.

New build mastic in Michelmersh, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference since hurried prep is behind a lot of new-build failures. We work on show homes, windows & doors and skirting & floors, and people most often call us about beads laid onto grit and dust from the build and frame joints opening as the plaster dries.
For a small place like Michelmersh, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
All our work comes with our 12-month guarantee.

Can I do it myself?
A careful DIYer can reseal a simple joint, 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.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Common questions in Michelmersh
Can you do new build mastic in Michelmersh?
Yes, Michelmersh is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Can you help a landlord with a rental near Mottisfont & Dunbridge station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Is it worth resealing while the house is still settling?
Any seal that is leaking should be redone straight away. Cosmetic gaps can wait until the first year or two of movement has passed.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, large or small.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Resist patching a failed seal with a tube from the DIY shop
- Get a leaking seal dealt with straight away
- Put sealant faults on your snagging list early
- Use the extractor fan every time you shower
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
When to call us in Michelmersh
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly.
These are the problems we are asked about most:
- Worktop and upstand sealant coming away
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
- Gaps opening as the house dries out and settles
If you’ve bought a new home near Mottisfont & Dunbridge station, the sealant around baths, showers and frames is worth checking in the first year or two.
