Remedial sealant in Ranfurly, done properly
A joint that keeps letting you down needs more than another bead. It helps to have pictures when you email us at info@mrmastic.co.uk, along with when it was last resealed. We work on failed movement joints, shrunken worktop sealant and leaking tray & enclosure joints, and people most often call us about over-sealed joints coming away and sealant that came away because the surface wasn’t prepared.
A bathroom in a place like Ranfurly 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 guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re 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 fails, we can still redo it.
How the visit works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. Around Ranfurly, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks

How the job changes by surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. We rake that out where it can be removed and seal with a flexible product.
Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before we reseal.
What affects the cost of remedial sealant
Call for a quick quote. The main things that affect it are:
- The size of the job
- Whether there’s mould to deal with
- The product the joint needs
- Access and height
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
To make quoting easier, please include:
- Pictures of the joints, sent by email
- Where the property is
- The problem you’ve noticed
- How many joints, rooms or windows are involved
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will come back to you with a quote.

What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Cracks in the fitting rather than the joint
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before you book.
Surfaces we seal
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
Work for landlords, hotels and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Remedial sealant around Ranfurly
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 does not dry out. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Failed sealant around a bath or shower is worth sorting between tenancies.
Rented homes near Milliken Park station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

Do you need remedial sealant in Ranfurly?
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Signs it’s time to call us include:
- Mould trapped under a layer of silicone
- Sealant applied over old sealant that has lifted
- Products that weren’t meant for the joint
- Sealant that came away because the surface wasn’t prepared
If you live in an older home near Ranfurly Church of Scotland, older homes can move a little, which is hard on rigid grout and tired sealant.
