What the job involves on each surface
Show homes
Tired or marked sealant in a show home can be renewed. The old bead comes out and a clean new one goes in.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
New build mastic in Thurso, done properly
Failed shower seals, gaps along the skirting and messy beads are common items on a new-home snagging list. While the builder’s snagging or warranty period runs, report it to them first. We work on show homes, plot handovers and skirting & floors, and the jobs we see most are cracks appearing as a new home settles and kitchen sealant that has pulled off the wall.
A lot of new homes in Scotland are timber-framed, and they settle in their first years, which can open up skirting and floor joints early on.
Our work is backed for twelve months.

What affects the quote in Thurso
Your quote is based on your job. We take into account:
- The number and length of the joints
- Access and height
- Any mould that needs treating
- Any working-time requirements on site
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
What to tell us when you ask for a quote:
- Roughly how big the job is
- The address or postcode of the job
- How we’d reach the joints
- Any previous sealing or DIY work
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
When to call us in Thurso
Later trades and the final clean can damage fresh sealant. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
Most people get in touch when they notice something like this:
- Leaking shower tray seals in a new home
- Frame joints opening as the plaster dries
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
In and around Thurso, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Thurso questions
Is new build mastic in Thurso guaranteed?
All our work, in Thurso and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
I let a flat near Thurso station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear quote.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.
Do you cover Thurso?
Yes. We work in Thurso. For a quote, drop us a line at info@mrmastic.co.uk.

How to look after the new joints
So the new joints stay in good condition:
- Get a leaking seal dealt with right away
- Wait for the cure time before using a resealed shower
- Avoid scourers and strong chemicals on sealant
- Look at the sealant regularly in the first couple of years
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing to help keep mould away.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
New build mastic in Thurso: local notes
Thurso is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so it’s worth checking at snagging. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Thurso station, the sealant around baths, showers and frames is worth checking in the first year or two.
