New build mastic in Ardlui, done properly
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. We are often asked to deal with sealant applied over dusty or wet surfaces and smeared, uneven beads picked up at snagging, across plot handovers, show homes and windows & doors.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

What we are called out for in Ardlui
Sealant applied onto damp surfaces does not bond well. Site programmes don’t always leave time for joints to dry before the sealant goes on.
Look out for these signs:
- Cracked sealant around new window and door frames
- Gaps between new skirting and floors
- Leaking shower tray seals in a new home
- Sealant that never bonded to the surface
For new homes near Ardlui station, it’s worth checking the sealant early, while snags are still fresh.

What new build mastic looks like in Ardlui
Ardlui 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.
In and around Ardlui, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Leaks from pipes, valves or wastes, which need a plumber
- Movement caused by a poorly fitted tray or bath
- Structural cracks in walls or ceilings
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before booking.

Ardlui questions
I let a flat near Ardlui station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Can you do new build mastic in Ardlui?
Yes, Ardlui is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Is it worth resealing while the house is still settling?
Where water is getting through, do not wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
What should I tell you?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.
Do you take on second-fix sealing for builders?
Yes. We carry out plot mastic and second-fix sealing for builders and developers. Send us the plot schedule and we’ll quote.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we’re fully insured too.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we have agreed the job, you don’t need to watch us work.
What happens if it’s left?
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. A lasting seal starts with removing the old one completely. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask about the job first and send you a clear quote before any work starts.
Why us?
- We leave the area clean and tidy
- White, clear, grey or another colour, product permitting
- Any old sealant cut out fully, not covered over
- We agree the colour with you first

How to look after the new joints
After the cure time, these simple habits help:
- Watch for new gaps as the house dries out
- Wipe joints with warm soapy water
- Keep water off fresh sealant until it has cured
- Record problems with dated pictures
Do not stand on the bath edge or the lip of the tray. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
