What affects the quote in Sandwick
There’s no set price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- The old material and how stubborn it is
- The product the joint needs
- How easy the joints are to reach
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
You don’t need to know the technical terms. Just tell us:
- The rough size of the job
- How we’d reach the joints
- Where the property is
- Any previous sealing or DIY work
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Remedial sealant in Sandwick
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. Typical jobs include leaks that keep coming back after resealing and sealant peeling off a dusty or damp surface, across botched or over-sealed joints, failed movement joints and expansion joints.
A bathroom in a place like Sandwick gets the same daily wear as one in a city flat. Generally soft Scottish water means less limescale, but steam still lets mould into sealant and grout.
We stand behind the work with a 12-month guarantee, so you’re covered after we have gone.

How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. In smaller Scottish places, parking is usually less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
How to prepare
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Move anything stored near the joints

Advice
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Movement from fittings that aren’t supported
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.

What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. 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.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
Why us?
- White, clear, grey or another colour, product permitting
- We agree the colour with you first
- A 12-month guarantee on all work
- Experience in homes, commercial sites and hotels

Keeping the joints in good condition
So the new joints stay in good condition:
- Check trays and worktops do not move
- Deal with small splits early
- Always have old sealant cut out, not covered
- Air the bathroom so the sealant can dry
Keep the room ventilated: run the fan during and after showers, or open a window.
If a joint has failed more than once, stop resealing it. Have someone find out why, or the next bead will go the same way.
Bathrooms and kitchens in Sandwick
Sandwick is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Scottish Water supplies are generally soft, so limescale is less of a problem than in hard-water areas. Mould is another matter: a bathroom that stays damp still turns sealant and grout black.
In and around Sandwick, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Signs you need remedial sealant in Sandwick
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Any of these means the joints need attention:
- Products that weren’t meant for the joint
- Floor or wall movement joints that have failed
- Black mould underneath the bead
- Worktop sealant that has shrunk and split
For jobs in and around Sandwick, choosing the right material for each joint is as important as a tidy finish.

What the job involves on each surface
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
