What affects the cost of remedial sealant
We quote each job individually. These are the things that affect it:
- Whether there’s mould to deal with
- Working hours on commercial sites
- The old material and how stubborn it is
- Whether the work is at height
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What we need to know
When you call or email, it’s useful to know:
- Any previous sealing or DIY work
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- Photos by email, if that is easy
We quote each job on its own. Simply drop us a line at info@mrmastic.co.uk and describe the job and send pictures if you have them.
Remedial sealant for homes and businesses in Thrumster
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you email us at info@mrmastic.co.uk, along with when it was last resealed. We work on botched or over-sealed joints, mouldy bath & shower sealant and leaking tray & enclosure joints, and the jobs we see most are smears and lumps from a botched reseal and products that weren’t meant for the joint.
A bathroom in a place like Thrumster gets the same daily wear as one in a city flat. Limescale is less of a problem with Scotland’s generally soft water, but mould still takes hold in damp sealant and grout.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Why act early in Thrumster
Another bead over the top won’t fix a failed joint. It cannot bond to what’s underneath, so the leak carries on and there’s now more to remove. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Always have old sealant cut out, not covered
- Get the cause of a repeat leak found before resealing
- Run the fan after every shower
- Check trays and worktops don’t move
Keep the room ventilated: run the fan during and after showers, or open a window.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
What we do, step by step
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Around Thrumster, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We start by checking the joint for movement, leaks and the reason it failed.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Mention any tricky access

Advice
Common questions in Thrumster
I let a flat near Wick station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can go on one quote. You can drop us a line at info@mrmastic.co.uk with the details for a clear quote.
Is Thrumster in your area for remedial sealant?
Yes. Our work covers the whole of Scotland, and Thrumster is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear quote.
Which products do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
How long will it take to strip and reseal the joint?
Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours, and we confirm the time with your quote.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Do you have insurance?
Yes. We’re fully insured, and we’ve been doing sealant work for more than 20 years.
Can old silicone be taken off without scratching the tiles?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. Any existing damage is pointed out before work begins.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Should I try it myself first?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
- Movement from fittings that are not supported
If you’re not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before you book.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Failed movement joints
What else we do in Thrumster
Common problems we fix in Thrumster
Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.
It’s worth asking for a quote if you see:
- Dark patches showing through the sealant
- Kitchen joints letting water behind the worktop
- Caulk or the wrong sealant used in a wet area
- Smears and lumps from a botched reseal
For landlords with property near Wick station, botched sealant from a previous quick fix is easier to strip out between tenants.
What your quote should include
- Whether they’re fully insured
- Whether VAT is included
- Whether you can choose the colour
- Which sealant they’ll use, and why
What remedial sealant looks like in Thrumster
Thrumster is close to the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. But mould still grows into sealant and grout in a room that doesn’t dry out.
In and around Thrumster, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.
