New build mastic in Oban
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We work on kitchens, bathrooms & en suites and windows & doors, and common reasons people get in touch are gaps between new skirting and floors and frame joints opening as the plaster dries.
Around smaller Scottish places like Oban, new homes tend to be single plots or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Big or small, you get the same one-year guarantee.

Your questions about new build mastic in Oban
Will you come out to Oban?
Yes, Oban is covered. We work across all 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 Oban station. Can you help?
Yes, rental work is part of what we do. 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.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints.
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 we start.
Can I send you my snagging list?
Yes. Snagging lists are a common starting point for us. We agree the sealant items with you before any work starts.
Can you reseal over the builder’s sealant?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
Is the work guaranteed?
Yes, for a year. If anything is not right with the work within the year, let us know and we’ll sort it.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Why it’s worth doing now in Oban
Resealing everything on a snagging list in one visit is usually simpler than chasing joints one at a time. You get one visit and one clear quote to plan around. 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.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- One-year guarantee on every job
- Approved under the ARBOMaster scheme
- Over 20 years’ experience

New build mastic in Oban: local notes
Oban is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Oban is in the west of Scotland, which is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
If you’ve bought a new home near Oban station, the sealant around baths, showers and frames is worth checking in the first year or two.
Oban is in Argyll and Bute. Homes, rented property, offices and hotels in Oban can book us for new build mastic, old or new, large or small. The work is guaranteed for a year.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep photos and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Get a leaking seal dealt with right away
- Watch for new gaps as the house dries out
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What we are called out for in Oban
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Both fail early.
Any of these means the joints need attention:
- Joints pulling apart as timber shrinks
- Internal frame sealant that has split
- Gaps between new skirting and floors
- Sealant work across a run of new homes
In and around Oban, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What we do, step by step
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. In smaller Scottish places, parking is generally 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 start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Tell us if parking is tricky
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
