New Build Mastic in Strontian
Problem with your new-build sealant joints in Strontian? We cut out the old, prepare the joints and apply the right sealant.
- Shower seals failing in the first year or two
- Messy sealant that spoils new finishes
- Skirting joints opening in the first winter
How we handle new build mastic in Strontian
Building dust is behind a lot of failed new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly rather than sitting on a layer of grit. Common call-outs are for new-build shower sealant that has already split and cracked sealant around new window and door frames, on skirting & floors, windows & doors and plot handovers.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
We stand behind the work with a one-year guarantee.

What the job involves on each surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. We reseal it with a weatherproof, flexible sealant.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Signs you need new build mastic in Strontian
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints aren’t always given time to dry.
Signs it’s time to call us include:
- Second-fix sealing on new plots
- Frame joints opening as the plaster dries
- Sealant that never bonded to the surface
- Leaking shower tray seals in a new home
For jobs in and around Strontian, choosing the right material for each joint is as important as a tidy finish.

Why act early in Strontian
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. 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.
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk and we’ll give you an honest view and a quote.
Why book with us
- Quality sealants from Arbo and Everbuild
- Tidy, careful work
- We never seal over old sealant
- One-year guarantee on every job
Honest limits
Before you book, it’s worth knowing the limits:
- Deciding who is responsible under a builder’s warranty
- A tray or bath that is not properly supported, until it’s fixed
- Settlement cracks that need a surveyor
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we will tell you honestly before booking.

The process
At the end, we look at the finished work together and tell you how long to leave it. The visit itself generally takes anything from a few hours to several days, depending on the number of plots, depending on the amount of work. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- Each area is checked and left with its cure time.
Preparing for the visit
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

What new build mastic looks like in Strontian
Strontian 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. The west of Scotland is wetter than the east, which means plot mastic and the sealant in new homes has to cope with a lot of rain.
Around Strontian, as everywhere, new build mastic is only as good as the preparation behind it.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
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.
