New build mastic in Newyears Green
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first. We work on show homes, plot handovers and windows & doors, and common reasons people get in touch are sealant work across a run of new homes and gaps between new skirting and floors.
In a village or hamlet like Newyears Green, 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.
Big or small, it’s backed by our one-year guarantee in Newyears Green and across Buckinghamshire.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Signs you need new build mastic in Newyears Green
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry before the sealant goes on.
These are the problems we’re asked about most:
- Skirting joints opening in the first winter
- Frame joints opening as the plaster dries
- Untidy sealant flagged on a snagging list
- New-build shower sealant that has already split
Around Newyears Green, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
- Which colour the sealant will be
- The length of the guarantee
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can call 0345 464 0079 or send us an email with a few pictures and we’ll tell you. In a small place like Newyears Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours in a single home in most cases. In a small place like Newyears Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

It depends on the size of the job, but as a guide it takes a few hours in a single home. We will give you a better idea when we quote.
Is it worth trying it myself?

How long should I leave it?

Can you match the sealant colour to my new kitchen or bathroom?
White and clear are the most common, but other colours are available. We choose one to suit the room.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Record problems with dated pictures
- Raise failed sealant with the developer while you’re covered
- Ventilate bathrooms well, especially in the first year
- Get a leaking seal dealt with right away
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
Report failed sealant to the builder while you are in the snagging period. Once it ends, the repair may be down to you so report it promptly.
