New Build Mastic in South Town
Our applicators work in South Town on plot mastic for developers and snagging failed sealant in new homes. Old sealant removed completely, joints prepared properly.
- Smeared, uneven beads picked up at snagging
- Kitchen sealant that has pulled off the wall
- Shower seals failing in the first year or two
Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep water off fresh sealant until it has cured
- Open a window or run the fan after bathing
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
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.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you so report it promptly.
About our new build mastic in South Town
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation. If you have untidy sealant flagged on a snagging list and sealant that never bonded to the surface, we can help, whatever the surface.
Somewhere as small as South Town, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Whatever the size of the job, it’s backed by our one-year guarantee in South Town and across Hampshire.

Landlords, agents and businesses in South Town
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What affects the quote in South Town
We quote each job individually. These are the things that affect it:
- Mould in or behind the old joints
- The old material and how stubborn it is
- How many rooms, windows or areas are involved
- The product the joint needs
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
Photos help, but a description is a good start. Try to tell us:
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
- Where the job is, and your postcode
- Any access issues, like height or stairs
For new build mastic in South Town, phone 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
When something else is needed
To be straight with you, some problems need a different trade:
- Settlement cracks that need a surveyor
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
What we seal
- Plot handovers
- Skirting & floors
- Kitchens
- Bathrooms & en suites
- Show homes
- Windows & doors
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

FAQs for South Town

Why does sealant fail so quickly in new builds?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.

Do you need new build mastic in South Town?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Keep an eye out for any of the following:
- Sealant that never bonded to the surface
- Cracked sealant around new window and door frames
- Cracks appearing as a new home settles
- Messy sealant that spoils new finishes
For new homes near Alton station, it’s worth checking the sealant early, while snags are still fresh.
