New build mastic for homes and businesses in Lanark
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We’re often asked to deal with gaps between new skirting and floors and sealant work across a run of new homes, across windows & doors, bathrooms & en suites and plot handovers.
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.
Big or small, it’s backed by our one-year guarantee.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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, and the work is guaranteed for a year.
Why it’s worth doing now in Lanark
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, send an email to info@mrmastic.co.uk with pictures. In a place like Lanark, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please email us at info@mrmastic.co.uk.

Lanark: your questions answered
Is Lanark within the area you cover?
Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Lanark station. Can you help?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it.
Do you use white or clear sealant?
Most bathroom joints are white or clear, but sealant comes in other colours too. We match the colour to the finish before we begin.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. The old sealant always comes out first.
When is the sealant fully cured?
Cure times vary by product and the temperature. Before we leave, we will tell you the cure time.
Can I add another job to the visit?
Of course. Doing several areas at once is usually more efficient.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then drop us a line at info@mrmastic.co.uk.
Different surfaces, different methods
Plot handovers
Taking time over preparation reduces return visits. Dust from the build is removed first and primer used where needed.
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes anything from a few hours to several days, depending on the number of plots from start to finish. For a place like Lanark, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Each joint is checked for movement before work begins.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Clear items away from the joints we’re working on
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions
