New homes and floors in Inverarnan
Inverarnan 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 Inverarnan, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Don’t seal over failed sealant yourself
- Get a leaking seal dealt with right away
- Look at the sealant regularly in the first couple of years
- Keep photos and emails about snagging items
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
When to call us in Inverarnan
A new house holds a lot of water from the build, and it dries out over the first couple of years. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
The problems people generally mention when they call include:
- Sealant work across a run of new homes
- Sealant that never bonded to the surface
- Leaking shower tray seals in a new home
- Gaps opening as the house dries out and settles
For new homes near Ardlui station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before you book
- How much experience the applicator has
- When the joint can take water or movement
- How the colour is chosen
- What product goes in the joint

Why act early in Inverarnan
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, send an email to info@mrmastic.co.uk and we will give you an honest view and a quote.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, 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 a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
Inverarnan questions
Is Inverarnan in your area for new build mastic?
Yes, Inverarnan is within the area we cover. Our work covers the whole of Scotland. You can email us at info@mrmastic.co.uk and let us know what needs doing.
Do you work for landlords with property near Ardlui station?
Yes, we work for landlords and agents. You can email us at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Do you use white or clear sealant?
White and clear are the most common, but other colours are available. We choose one to suit the room and agree it with you.
Do you work through snagging lists?
Yes. Send us the sealant items on the list, with pictures if you can and we’ll give you a quote. We will tell you if anything on it is not a sealant job.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common as timber and plaster dry out. Poor preparation at handover adds to it.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
