About our new build mastic in Milngavie
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over with a sealant suited to each area. We work on plot handovers, show homes and windows & doors, and common reasons people get in touch are second-fix sealing on new plots and smeared, uneven beads picked up at snagging.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

How long does the job take?
As a guide, most jobs take a few hours for most snagging lists, longer for a run of plots. Bigger jobs take longer.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take a few hours in a single home. Outside jobs in Milngavie need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts
- Tell us about access, such as stairs, a lift or high-level joints

What affects the quote in Milngavie

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
- Keep pictures and emails about snagging items
- Report sealant problems to your builder during the snagging period
Don’t stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Left alone, a small crack can become a leak.
What new build mastic looks like in Milngavie
Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.

Why act early in Milngavie
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Around Milngavie, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

DIY versus a professional finish
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
