Bathroom resealing for homes and businesses in Gelston
It isn’t only bathrooms. The joint between worktop and wall, the edge of the sink and the bottom of the splashback all take splashes every day, and water that gets into the back edge of a worktop can swell the board. Kitchen joints get a sealant suited to kitchens, colour-matched where it shows. If you have smears of silicone across the tiles and damp behind the bath or under the tray, we can put it right, whatever the surface.
In and around a place like Gelston, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are normally the first signs.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Bathrooms and kitchens in Gelston
Scotland’s water is generally soft, so sealant and grout see less limescale than in much of England. Mould is another matter: a bathroom that stays damp still turns sealant and grout black. In Scotland, private landlords have to meet the Repairing Standard, which covers keeping fixtures and fittings in a reasonable state of repair. Tired, leaking sealant is worth putting right before a new tenant moves in.
Around Gelston, as everywhere, bathroom resealing is only as good as the preparation behind it.

The process
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a couple of hours for a single bath or shower. Outdoor work around Gelston depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- Protection goes down around the bath, shower or worktop.
- We cut away the old sealant and clean off what’s left.
- We treat any mould and let the joint dry properly.
- Any bath is filled with water, then we lay a bead of anti-fungal silicone in white, clear or a matching colour.
- The joint is finished neatly and we explain when it can get wet.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on

Advice
Surface by surface
Basins & vanity units
Basins take less water than showers, but the joint behind them is splashed every day. Old sealant there often goes black at the corners, so it’s cut out and renewed just like a bath joint.
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, because cooking grease stops sealant bonding. Proper degreasing is what helps the new joint last.
Honest limits
A few problems are outside what sealant work can do:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Cracks in the tray itself rather than the joint
- A bath or tray that moves because it is not properly supported
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Gelston: your questions answered
Can you do bathroom resealing in Gelston?
Yes, Gelston is within the area we cover. We work across all of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Is Gelston within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
How long does it take to reseal a bath or shower?
A single bath or shower takes about a couple of hours, old sealant removal included. A full bathroom and kitchen can take most of a day.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Do you work for hotels and businesses?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

What else we do in Gelston
Common problems we fix in Gelston
Older sealant shrinks and hardens. Along worktops it tends to pull back from the wall, opening a hairline gap that lets water and crumbs in. Heat from the hob and strong sprays speed it along.
It’s worth asking for a quote if you see:
- Cracked, shrunken or lifting silicone
- Leaking joints on a shower screen
- Black spots spreading through the bead
- Smears of silicone across the tiles
In the older streets around Kirkland Of Gelston, walls and floors in older homes can move, and sealant and grout show it first.

Why it’s worth doing now in Gelston
Tired sealant isn’t a reason to replace a bath or shower. A new bead often brings the whole room back, provided the bath, tray and tiles are in good order. If we find a deeper problem, you will hear it from us. Exposed walls in smaller Scottish places take a lot of wind and rain, 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. We give a clear quote before we start.
What you get with us
- Colour agreed with you before any work starts
- Full insurance on every job
- We leave the area clean and tidy
- Experience in homes, commercial sites and hotels

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
