New build mastic in Milton-under-Wychwood
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. We’re often asked to deal with internal frame sealant that has split and sealant that never bonded to the surface, across bathrooms & en suites, plot handovers and skirting & floors.
Around Milton-under-Wychwood, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Whatever the size of the job, it’s backed by our 12-month guarantee in Milton-under-Wychwood and across Oxfordshire.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Open a window or run the fan after bathing
- Record problems with dated pictures
- Follow the cure time we give you
- Avoid scourers and strong chemicals on sealant
Watch the joints as the house settles. Small gaps can appear as the house dries, and they’re simple to reseal once movement has slowed.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. Somewhere as small as Milton-under-Wychwood, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit

Surface by surface
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one that suits the frame.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.

Is it normal for sealant to crack in a new home?
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.
Can you do several jobs on one visit?
Yes, we can. More than one area can be quoted together.
Can you reseal over the builder’s sealant?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Can I send you my snagging list?
