Different surfaces, different methods
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. We reseal them with a flexible sealant.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
How we handle new build mastic in Milton
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. Typical jobs include shower seals failing in the first year or two and joints pulling apart as timber shrinks, on skirting & floors, kitchens and windows & doors.
Scotland’s cities are still adding new flats and houses, and new-home owners often find sealant snags in the first year or two.
All of our work is guaranteed for twelve months.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Resist patching a failed seal with a tube from the DIY shop
- Follow the cure time we give you
- Keep pictures and emails about snagging items
- Clean sealant with mild detergent, not abrasives
Leave the sealant for the cure time we give you before showering or bathing. Silicone is normally left for about a day.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.

New build mastic around Milton
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. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
For new homes near Possilpark & Parkhouse station, it’s worth checking the sealant early, while snags are still fresh.

When you call or email, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Whether it has been sealed before
- Roughly how big the job is
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you are ready, send an email to info@mrmastic.co.uk.
Why act early in Milton
DIY kits do not solve the main problems with new-build sealant: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. For landlords in Milton, damp and leaks can be a Repairing Standard issue, so failed sealant is best replaced before it becomes a complaint.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- A tray or bath that isn’t properly supported, until it’s fixed
- Leaks from pipes, valves or wastes, which need a plumber
- Damaged fittings that need replacing

The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Many homes in Scotland’s cities are tenement flats, reached through a shared close and up a common stair. In Milton, it helps to know the floor, the door entry arrangements and the nearest parking.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Preparing for the visit
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

What we’re called out for in Milton
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant around new window and door frames
- Second-fix sealing on new plots
- Skirting joints opening in the first winter
- Gaps behind new kitchen upstands
Around Milton, as everywhere, new build mastic is only as good as the preparation behind it.
