Remedial sealant & repairs in Gillock, Highland
Our applicators work in Gillock on removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- A shower that leaks however often it’s resealed
- Thick, messy sealant smeared over tiles
- Dark patches showing through the sealant
Aftercare tips
After the cure time, these simple habits help:
- Get the cause of a repeat leak found before resealing
- Clean sealant with mild products only
- Never fill a movement joint with mortar or grout
- Report a tray that rocks or a worktop that lifts
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Mould trapped under over-sealed joints spreads unseen. By the time it shows through, the joint is well past saving.
Remedial sealant for homes and businesses in Gillock
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, then a flexible sealant matched to the movement goes in. We work on botched or over-sealed joints, mouldy bath & shower sealant and failed movement joints, and common reasons people get in touch are over-sealed joints coming away and kitchen joints letting water behind the worktop.
A bathroom in a place like Gillock 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.
The work is covered for a year after we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

What happens on the day
Once we are on site, 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 most joints, depending on how much old sealant has to come out. In smaller Scottish places, parking is generally 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.
- We start by checking the joint for movement, leaks and the reason it failed.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Let us know about earlier repairs to the joints
- Clear the area around the work
- Let us know if you’ve seen damp or leaks

Why deal with it now?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. Dealing with the joint now is a small job by comparison. In a place like Gillock, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- We agree the colour with you first
- Anti-fungal silicone where joints get wet
- ARBOMaster approved applicator
- A sealant colour to suit the surroundings

Gillock: your questions answered
Do you work for landlords with property near Georgemas Junction station?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Is Gillock in your area for remedial sealant?

Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Gillock, along with the rest of our area.
Can you strip sealant from an acrylic tray safely?
Yes. Residue is removed with a product suited to the surface rather than scraped hard, so the new sealant bonds cleanly.
Can you fix a reseal that hasn’t worked?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Movement from fittings that are not supported
- Sealant in an older building that needs testing for asbestos first
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.

What remedial sealant looks like in Gillock
Private landlords in Scotland must be registered and meet the Repairing Standard, which includes keeping fixtures and fittings in reasonable repair. Tired, leaking sealant is worth putting right before a new tenant moves in. 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 and around Gillock, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint. Rented homes near Georgemas Junction station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
