New-build mastic & snagging in East Lockinge, Oxfordshire
Our applicators work in East Lockinge on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Cracked sealant around new window and door frames
- Beads laid onto grit and dust from the build
- Gaps behind new kitchen upstands
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
About our new build mastic in East Lockinge
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, because that’s what rushed new-build sealant generally lacks. We work on show homes, windows & doors and bathrooms & en suites, and common reasons people get in touch are internal frame sealant that has split and gaps behind new kitchen upstands.
Work in a small place like East Lockinge just needs the journey and access planning, and once on site, the job is the same as anywhere.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Report sealant problems to your builder during the snagging period
- Act quickly if a seal starts to leak
- Avoid scourers and strong chemicals on sealant
- Open a window or run the fan after bathing
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.

What we are called out for in East Lockinge
The first winter with the heating on dries a new home quickly. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
If you can see any of these, it’s time to have the joints looked at:
- Gaps opening as the house dries out and settles
- Sealant work across a run of new homes
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
For jobs in and around East Lockinge, choosing the right material for each joint is as important as a tidy finish.
What your quote should include
- How the surfaces are prepared before sealing
- How much experience the applicator has
- Which colour the sealant will be
- Whether they seal over old material or remove it
