How we handle new build mastic in Kelloholm
Some new-home owners let the house settle before resealing. For small cosmetic gaps, that is reasonable, but a seal that’s letting water through needs doing now. Common call-outs are for plot mastic for developers ahead of handover and cracked sealant around new window and door frames, on skirting & floors, bathrooms & en suites and windows & doors.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
After the cure time, these simple habits help:
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
- Ventilate bathrooms well, especially in the first year
- Resist patching a failed seal with a tube from the DIY shop
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.

To make quoting easier, please include:
- Any previous sealing or DIY work

DIY versus a professional finish
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 a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Your questions about new build mastic in Kelloholm
Do you cover smaller places like Kelloholm?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Kelloholm for new build mastic?
Yes, Kelloholm is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and tell us what needs doing.
Will you just run a new bead over the existing one?
No. Over-sealing traps mould and water and soon fails. All the old sealant comes out before work begins.
Do you use white or clear sealant?
That depends on what the joint meets: white or clear in most bathrooms, and a colour to suit worktops, frames and floors elsewhere. We agree the colour before work begins.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Both lead to early failure.
What sealant do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.

Why it’s worth doing now in Kelloholm
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. In an older home around Kelloholm, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.
