About our new build mastic in Tarbert
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you have gaps between new skirting and floors and messy sealant that spoils new finishes, we can help.
Around smaller Scottish places like Tarbert, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
Every job is covered by a one-year guarantee.

Tarbert: your questions answered
Do you cover Tarbert for new build mastic?
Yes, Tarbert is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job, and we will give you a clear quote.
Will you come out to Tarbert?
Yes, smaller places are covered as well as towns. We work across all of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for hotels and businesses?
Yes. Larger jobs can be planned room by room or area by area.
Is it normal for sealant to crack in a new home?
There are usually two causes: the house moving as it dries, and sealant that never bonded properly. A proper reseal deals with both.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the number of plots. We will tell you when we quote.
I’m a tenant. Can you help?

Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
How the job changes by surface
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
Skirting and floors
As timber and screed dry, skirting and floors shift. Caulk cracks; a flexible sealant moves with it painted or coloured to suit.
New build mastic in Tarbert: local notes
Tarbert 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. Work on the islands has to be planned around ferry crossings and the weather, so the more notice, the better.
Around Tarbert, as everywhere, new build mastic is only as good as the preparation behind it.

Signs you need new build mastic in Tarbert
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
If you can see any of these, it’s time to have the joints looked at:
- Second-fix sealing on new plots
- New-build shower sealant that has already split
- Cracked caulk along new skirting
- Joints pulling apart as timber shrinks
Whether the job is in Tarbert itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before booking
- When the joint can take water or movement
- Which sealant they’ll use, and why
- Who does the work, and how experienced they are
- Are they insured?
When something else is needed
We will not take on work that will not last, so here’s what sealant cannot put right:
- Movement caused by a poorly fitted tray or bath
- Disputes or warranty claims with your builder
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
Surfaces we seal
- Plot handovers
- Kitchens
- Show homes
- Windows & doors
- Bathrooms & en suites
- Skirting & floors
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Wait for the cure time before using a resealed shower
- Look at the sealant regularly in the first couple of years
- Report sealant problems to your builder during the snagging period
- Record problems with dated photos
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you, so raise it early.

Advice
Landlords, agents and businesses in Tarbert
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
