Honest limits
Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- A tray or worktop that needs refixing first
- Failed tanking or loose tiles behind the sealant
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.

How we quote for remedial sealant
There’s no set price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- Whether old sealant or filler has to be cut out
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.
Helping us quote
To make quoting easier, let us know:
- What the problem is, such as mould, gaps, leaks or cracking
- The address or postcode of the job
- If someone has resealed it before
- The rough size of the job
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
Signs you need remedial sealant in Castledykes
Joints that move need sealant that can stretch. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
People generally contact us when they notice one of these:
- Kitchen joints letting water behind the worktop
- Thick, messy sealant smeared over tiles
- Sealant applied over old sealant that has lifted
- Black mould underneath the bead
Managing a site like Dumfries Academy? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

What happens if it’s left?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Around Castledykes, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

Questions from Castledykes
Is Castledykes within the area you cover?
Yes. Castledykes is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for hotels and guest houses in Castledykes?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Can old silicone be taken off without scratching the tiles?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
What if the leak isn’t the sealant?
We will tell you. A cracked tray, faulty valve or leaking waste needs a different trade, and we will not reseal for the sake of it.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all.
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.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Check ceilings under showers for marks
- Get the cause of a repeat leak found before resealing
- Don’t point over movement joints
- Clean sealant with mild products only
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old, so the old bead should always come out first.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into whatever is behind or below. Early action keeps it to a sealant job.
What happens on the day
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before we start. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a place like Castledykes, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- On commercial sites, let us know about site rules
- Let us know if you’ve seen damp or leaks
