New-build mastic & snagging in Polmadie, Glasgow
Problem with your new-build sealant joints in Polmadie? We remove the old material, prepare the joints and seal them properly.
- Internal frame sealant that has split
- Gaps behind new kitchen upstands
- Skirting joints opening in the first winter
Common problems we fix in Polmadie
New homes are full of moisture from plaster, screed and concrete, and it dries out over the first couple of years. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
People usually contact us after spotting one of these:
- Sealant applied over dusty or wet surfaces
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
- Cracked sealant around new window and door frames
Around Polmadie, as everywhere, new build mastic is only as good as the preparation behind it.

How we handle new build mastic in Polmadie
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. We work on skirting & floors, bathrooms & en suites and kitchens, and the jobs we see most are second-fix sealing on new plots and sealant that never bonded to the surface.
In older Scottish city flats, floors are often timber over joists, with skirting joints that open and close with the seasons. For a flat in Polmadie, a flexible sealant copes with that movement where filler would crack.
All our work is covered by a one-year guarantee.

New build mastic in Polmadie: local notes
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. Polmadie is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
If you’ve bought a new home near Croftfoot station, the sealant around baths, showers and frames is worth checking in the first year or two.

Polmadie questions
Is new build mastic in Polmadie guaranteed?
All our work, in Polmadie and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you work for landlords with property near Croftfoot station?
Yes. We work for landlords and letting agents as well as householders. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we will send you a clear quote.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
How long should I leave it?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Should I go to my builder first?
Start with the builder if you are in the snagging or warranty period. If it isn’t resolved, we’ll cut it out and reseal it.
Do you take on second-fix sealing for builders?
Yes. We take on second-fix sealant work across new plots. Good preparation keeps snagging to a minimum.
Are you fully insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can new sealant go on top of the old bead?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.

Looking after it afterwards
To keep the joints looking good and working properly:
- Wipe joints with warm soapy water
- Open a window or run the fan after bathing
- Check bath and shower seals every few months as the house settles
- Keep pictures and emails about snagging items
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day.
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 affects the cost of new build mastic
Jobs vary more than people expect. What affects the quote:
- Access and height
- Whether there’s mould to deal with
- The number of rooms or windows
- The size of the job
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
Before you ask for a quote, have a think about:
- A few photos by email, if you can
- Where the job is, and your postcode
- Whether it has been sealed before
- Any access issues, like height or stairs
