New build mastic for homes and businesses in Polbeth
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. If you have leaking shower tray seals in a new home and internal frame sealant that has split, we can put it right, whatever the surface.
Work in a place like Polbeth is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Why it’s worth doing now in Polbeth
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.

What new build mastic looks like in Polbeth

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
When to call us in Polbeth
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry before the sealant goes on.
People usually contact us when they notice something like this:
- Second-fix sealing on new plots
- Gaps opening as the house dries out and settles
- Beads laid onto grit and dust from the build
- Internal frame sealant that has split
If you’ve bought a new home near West Calder station, the sealant around baths, showers and frames is worth checking in the first year or two.

How the visit works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It usually takes anything from a few hours to several days, depending on the number of plots.

- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.

What should I tell you?
A short description and the location, with photos by email if possible. We’ll ask anything else we need to know.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you use white or clear sealant?
It depends on the joint: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We will agree it with you first.
Do you guarantee your work?
Yes, for a year. If anything isn’t right with the work within the year, let us know and we will sort it.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Put sealant faults on your snagging list early
- Avoid scourers and strong chemicals on sealant
- Do not wait for the house to settle if water is getting through
- Resist patching a failed seal with a tube from the DIY shop
Clean the sealant with a mild detergent and a soft cloth. Keep scourers and harsh chemicals off it, which can damage the surface.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
