New-build mastic & snagging in Cookley Green, Oxfordshire
New build mastic across Cookley Green and nearby, with old sealant always removed completely.
- Gaps opening as the house dries out and settles
- Leaking shower tray seals in a new home
- Cracked caulk along new skirting
Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
About our new build mastic in Cookley Green
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. If you have shower seals failing in the first year or two and plot mastic for developers ahead of handover, we can put it right, whatever the surface.
Somewhere as small as Cookley Green, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
Whatever the size of the job, it’s backed by our one-year guarantee in Cookley Green and across Oxfordshire.

The process
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work starts. Most jobs take a few hours for most snagging lists, longer for a run of plots. In a small place like Cookley Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Each joint is cleaned of dust and grit, then primed if required.
- We apply a sealant that suits each joint and tool it to a neat finish.
- Finally, each room is checked and you’re given the cure time.
Getting ready for the visit
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

What sealant work cannot fix
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Plumbing faults behind the sealant
- Structural cracks in walls or ceilings
- Broken tiles or a split tray
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

What new build mastic looks like in Cookley Green
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

What happens if it’s left?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around Cookley Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before we start.

Do you need new build mastic in Cookley Green?
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Keep an eye out for any of the following:
- Gaps between new skirting and floors
- Internal frame sealant that has split
- Kitchen sealant that has pulled off the wall
- Sealant that never bonded to the surface
For jobs in and around Cookley Green, choosing the right material for each joint is as important as a tidy finish.
Comparing quotes
- Whether VAT is included
- How much experience the applicator has
- Which colour the sealant will be
- When the joint can take water or movement
Looking after it afterwards
So the new joints stay in good condition:
- Wait for the cure time before using a resealed shower
- Keep pictures and emails about snagging items
- Check bath and shower seals every few months as the house settles
- Open a window or run the fan after bathing
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
