New Build Mastic in South Warnborough

- Joints pulling apart as timber shrinks
New build mastic in South Warnborough, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you’re dealing with shower seals failing in the first year or two and worktop and upstand sealant coming away, we can put it right, whatever the surface.
Somewhere as small as South Warnborough, 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.
All our work is covered by our one-year guarantee, wherever you are in Hampshire.

What the job involves on each surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out.
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one.

Common questions in South Warnborough
Do you work for landlords with property near Hook station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Do you cover smaller places like South Warnborough?
Yes, South Warnborough is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix doesn’t last, we can help.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule ready for handover. Get in touch with the number of plots and the scope and we’ll quote.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We’ll agree it with you first.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

When to call us in South Warnborough
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly, and the problem shows up after you move in.
Any of these means the joints need attention:
- Sealant applied over dusty or wet surfaces
- Kitchen sealant that has pulled off the wall
- Cracked caulk along new skirting
- Leaking shower tray seals in a new home
For new homes near Hook station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote
- What happens if the job turns out different
- How the joint is cleaned and prepared
- When the joint can take water or movement
- Which sealant they’ll use, and why
Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like South Warnborough, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.
Why us?
- Every job guaranteed for a year
- An ARBOMaster approved applicator
- Any old sealant cut out fully, not covered over
- White, clear, grey or coloured to suit, where the product allows

How to look after the new joints
After the cure time, these simple habits help:
- Check bath and shower seals every few months as the house settles
- Put sealant faults on your snagging list early
- Follow the cure time we give you
- Don’t wait for the house to settle if water is getting through
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture does not sit on the sealant.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
