How we handle new build mastic in Over Wallop
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so the joint is cut out, cleaned, dried and resealed. We work on plot handovers, kitchens and windows & doors, and people most often call us about skirting joints opening in the first winter and gaps opening as the house dries out and settles.
In a village or hamlet like Over Wallop, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Every job comes with our one-year guarantee, wherever you are in Hampshire.

Questions from Over Wallop
Can you do new build mastic in Over Wallop?
Yes, Over Wallop is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing.
Is Over Wallop within the area you cover?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
How long does the job take?
Most jobs take a few hours in a single home, including the preparation. We’ll confirm how long when we quote.
Is it worth resealing while the house is still settling?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply ring 0345 464 0079 or email us.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
Is there any odour?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Clean sealant with mild detergent, not abrasives
- Put sealant faults on your snagging list early
- Photograph failed sealant before it’s redone
- Keep water off fresh sealant until it has cured
Avoid standing on the rim of the bath or the edge of the tray. Report any movement in a bath or tray.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.

What we’re called out for in Over Wallop
Sealant is often one of the last jobs before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
Common reasons people contact us include:
- Sealant applied over dusty or wet surfaces
- Internal frame sealant that has split
- Worktop and upstand sealant coming away
- Leaking shower tray seals in a new home
For new homes near Grateley station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- What insurance they hold
- Who does the work, and how experienced they are
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
When it isn’t the sealant
New sealant cannot fix everything, and we will tell you before any work starts. Sealant will not put right:
- Broken tiles or a split tray
- Your warranty claim itself, which is between you and the builder
- Leaks from pipes, valves or wastes, which need a plumber
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.
