New build mastic in St Cyrus
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 sealant actually sticks. If you have new-build shower sealant that has already split and cracked sealant around new window and door frames, we can help, whatever the surface.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
St Cyrus: your questions answered
Will you come out to St Cyrus?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Montrose station. Can you help?
Yes, rental work is part of what we do. You can drop us a line at info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before any work starts.
Can I add another job to the visit?
Yes, we can. More than one area can be quoted together.
How long should I leave it?
Different products cure at different speeds, so please follow the time we give you when we finish.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we’re done.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can new sealant go on top of the old bead?
No. New silicone will not bond to old silicone, so sealing over the top fails quickly. The old sealant always comes out first.
Why it’s worth doing now in St Cyrus
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and send you a clear quote before any work starts.

What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours in a single home, and we tell you how long to leave it before we go. Outdoor work around St Cyrus depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Mention any leaks or damp you’ve noticed

Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Record problems with dated pictures
- Report sealant problems to your builder during the snagging period
- Wipe joints with warm soapy water
- Look at the sealant regularly in the first couple of years
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant.

- Access and height
