About our new build mastic in Gateside
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. We work on skirting & floors, windows & doors and plot handovers, and common reasons people get in touch are worktop and upstand sealant coming away and smeared, uneven beads picked up at snagging.
Work in a place like Gateside is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
You get a 12-month guarantee, the same in Gateside as everywhere else we work.

Keeping the joints in good condition
Looking after new joints is easy:
- Avoid scourers and strong chemicals on sealant
- Avoid running a DIY bead over the old one
- Look at the sealant regularly in the first couple of years
- Put sealant faults on your snagging list early
Do not stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.

Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.
Signs you need new build mastic in Gateside
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes don’t always leave time for joints to dry.
Most people get in touch after spotting one of these:
- Skirting joints opening in the first winter
- Worktop and upstand sealant coming away
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
Whether the job is in Gateside itself or nearby, the right material for each joint matters as much as a neat finish.

New homes and floors in Gateside
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.

What we do, step by step
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours in a single home. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- We look at why each joint failed, including any movement.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
Before we arrive
- Mention any tricky access
- For business premises, tell us about site rules or sign-in
- Mention any parking rules near the property

What affects the quote in Gateside
There’s no set price list, because jobs vary so much. What we look at:
- Access and height
- Whether there’s mould to deal with
- The product the joint needs
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- What’s wrong with the joints now
- If someone has resealed it before
- Any access issues, like height or stairs
- The rough size of the job
We do not publish a price list. Instead, your job gets its own clear quote. To arrange one, drop us a line at info@mrmastic.co.uk.
Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Cutting out, cleaning and priming are what make the difference. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.
Why us?
- One-year guarantee on every job
- Full insurance on every job
- Neat joints and a tidy finish
- Old sealant always removed completely
