About our new build mastic in College Milton
Across College Milton, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. If you have sealant work across a run of new homes and sealant that never bonded to the surface, we can help, whatever the surface.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
The process
There isn’t much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours in a single home, including the tidy-up. Somewhere like College Milton may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- 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.
- Each area is checked and left with its cure time.
Before we arrive
- On commercial sites, let us know about site rules
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

How we quote for new build mastic
We quote each job individually. These are the things that affect it:
- How much old sealant there is and how hard it is to remove
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- Working hours on commercial sites
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

New build mastic in College Milton: local notes
College Milton is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
In and around College Milton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For new homes near Hairmyres station, it’s worth checking the sealant early, while snags are still fresh.
College Milton is about 1 mile north-west of East Kilbride, in South Lanarkshire. Jobs in College Milton get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. Our area takes in 139 places across South Lanarkshire. You can also see our page for Glasgow, about 6 miles away.

How to look after the new joints
A little care helps the new joints last. Our advice:
- Follow the cure time we give you
- Act quickly if a seal starts to leak
- Put sealant faults on your snagging list early
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing so moisture does not sit on the sealant.
Report failed sealant to the builder while you’re in the snagging period. After that, putting it right may fall to you, so raise it early.
When it is not the sealant
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Settlement cracks that need a surveyor
- Leaking fittings rather than failed sealant
- Your warranty claim itself, which is between you and the builder
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.

Why it’s worth doing now in College Milton
If you are still in the builder’s snagging or warranty period, ask them to put it right first. If it keeps failing or isn’t dealt with, we can reseal it properly. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
Why book with us
- A sealant colour to suit the surroundings
- Any old sealant cut out fully, not covered over
- Approved under the ARBOMaster scheme
- 180+ five-star Google reviews

Is there a guarantee?
Yes. All our work carries our 12-month guarantee.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. If something is not sealant, we will say so.
Why has my new-build shower seal failed already?
New homes dry out and move in their first couple of years, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Should I wait before resealing?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
