New build mastic in Tong
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. If you have worktop and upstand sealant coming away and sealant applied over dusty or wet surfaces, we can put it right, on kitchens, show homes and windows & doors alike.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
There’s a 12-month guarantee on every job, large or small.

Helping us quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- The type of property
- Photos by email, if that’s easy
- The rough size of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that is easy.
Aftercare tips
Aftercare is simple, and it makes a real difference:
- Don’t seal over failed sealant yourself
- Get a leaking seal dealt with straight away
- Check bath and shower seals every few months as the house settles
- Record problems with dated pictures
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
What the job involves on each surface
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens.

What does new build mastic cost?
Every job is different, so each one gets its own quote. For a quick quote, email us at info@mrmastic.co.uk with a short description of the job.

Who should fix failed sealant in a new build?
If you’re still within the builder’s snagging or warranty period, report it to them first. If it isn’t sorted, or keeps failing, get in touch with us.
What colour sealant will you use?
We use white, clear or a colour to suit the finishes. Tell us what you’d like when you get a quote.
Can you do plot mastic on a new development?
Yes. We work through plots to your schedule ready for handover. Tell us the plots and the joints involved for a clear quote.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
New build mastic around Tong

Common problems we fix in Tong
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry first.
Look out for any of the following:
- Shower seals failing in the first year or two
- Sealant that never bonded to the surface
- Worktop and upstand sealant coming away
- Messy sealant that spoils new finishes
For jobs in and around Tong, choosing the right material for each joint is as important as a tidy finish.
What your quote should include
- When the joint can take water or movement
- Whether all the old sealant comes out first
- What happens if they find a problem under the old sealant
- What product goes in the joint
