New build mastic in Fort William, done properly
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. If you are dealing with sealant applied over dusty or wet surfaces and shower seals failing in the first year or two, we can help.
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.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we’ll put it right.

What sealant work cannot fix
In fairness, there are a few things sealant will not fix:
- Damaged fittings that need replacing
- Leaks from pipes, valves or wastes, which need a plumber
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

New build mastic in Fort William: local notes
Fort William is within about 1 mile of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. 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.
For new homes near Fort William station, it’s worth checking the sealant early, while snags are still fresh.

Fort William: your questions answered
Do you work for landlords with property near Fort William station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Can you do new build mastic in Fort William?
Yes. Our work covers the whole of Scotland, and Fort William is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. If something isn’t sealant, we will say so.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Will you just run a new bead over the existing one?
No. New silicone won’t bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we’re using and why.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Why it’s worth doing now in Fort William
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time, and they’re avoidable with good preparation. In an older home around Fort William, damp from a failed joint can get into timber and plaster.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk and we will talk you through it.

Do you need new build mastic in Fort William?
A new house holds a lot of water from the build, which takes a year or two to dry out. As it does, timber shrinks and joints open and the sealant has to cope with the movement.
The problems people normally mention when they call include:
- Beads laid onto grit and dust from the build
- New-build shower sealant that has already split
- Skirting joints opening in the first winter
- Gaps opening as the house dries out and settles
In and around Fort William, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
