New-build mastic & snagging in Charlestown, Highland
New-build sealant joints in Charlestown need attention? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Plot mastic for developers ahead of handover
- Gaps behind new kitchen upstands
- Shower seals failing in the first year or two
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Photograph failed sealant before it’s redone
- Follow the cure time we give you
- Get a leaking seal dealt with right away
- Raise failed sealant with the developer while you’re covered
Follow the cure time we give you before the area gets wet. Most silicones need around a day.
Early snagging is easier snagging. Left alone, a small crack can become a leak in a busy bathroom.
About our new build mastic in Charlestown
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first. We work on skirting & floors, windows & doors and kitchens, and the jobs we see most are second-fix sealing on new plots and worktop and upstand sealant coming away.
Around smaller Scottish places like Charlestown, 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.
Our work is backed for twelve months.

When to call us in Charlestown
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
The most common problems we see are:
- Sealant that never bonded to the surface
- Kitchen sealant that has pulled off the wall
- Gaps between new skirting and floors
- Internal frame sealant that has split
For new homes near Inverness station, it’s worth checking the sealant early, while snags are still fresh.

New build mastic in Charlestown: local notes
Charlestown is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Charlestown is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
Around Charlestown, as everywhere, new build mastic is only as good as the preparation behind it.

How the job changes by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
What happens if it’s left?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Around Charlestown, water from a failed joint in an older stone home can soak into timber and plaster.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll explain what it covers.
What you get with us
- Experience in homes, commercial sites and hotels
- A 12-month guarantee on all work
- Approved under the ARBOMaster scheme
- We agree the colour with you first

How it works
You do not need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the number of plots in most cases. For a place like Charlestown, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- 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.
How to prepare
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

What sealant work cannot fix
In fairness, some problems need a different trade:
- A tray or bath that is not properly supported, until it’s fixed
- Damaged fittings that need replacing
- Deciding who is responsible under a builder’s warranty
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.
