Colgrain Bathroom Resealing
Bath, shower, basin, wet room, worktop and sink resealing for homeowners, landlords and businesses in Colgrain. Fully insured, ARBOMaster approved and guaranteed for a year.
- Water getting behind the kitchen upstand
- Smears of silicone across the tiles
- Black spots spreading through the bead
Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Bathroom resealing for homes and businesses in Colgrain
A fresh bead of silicone changes how a bathroom looks more than most people expect. Mouldy silicone makes even a new bathroom look neglected, and a neat new joint puts that right in a short visit. Just as important, it closes the gaps water would otherwise get through. We work on shower trays & enclosures, kitchen worktops & upstands and basins & vanity units, and common reasons people get in touch are a bead that has pulled away from the tiles and water escaping at the shower enclosure.
In and around a place like Colgrain, homes range from older stone-built properties to newer houses. Where a building moves, cracked grout and split sealant are usually the first signs.
A one-year guarantee comes as standard, so you’re covered after we have gone.

When it is not the sealant
Before you book, it’s worth knowing the limits too:
- Cracked or missing grout between tiles (that is regrouting)
- A leaking waste, trap or valve
- Damage behind the tiles that needs a tiler

Leave it or put it right?
A failed joint gets more costly to put right the longer it’s left. Water that gets behind a bath soaks into the floor, the panel and sometimes the ceiling below, and that’s a far bigger job than a reseal. Around Colgrain, water from a failed joint in an older stone home can soak into timber and plaster.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes two to three hours for a typical bath, depending on how much old sealant there is. Outdoor work around Colgrain 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.
- Baths are filled first, then anti-fungal sanitary silicone is applied in a colour to suit.
- The joint is finished neatly and we explain when it can get wet.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints

Common problems we fix in Colgrain
Sealing over old silicone is one of the commonest mistakes we find. Fresh silicone cannot grip the old bead underneath, so it lifts, lets water in and traps mould underneath.
Keep an eye out for any of the following:
- Two layers of silicone, both failing
- Gaps between the worktop and the wall
- Smears of silicone across the tiles
- Mouldy sealant that has gone black

What bathroom resealing looks like in Colgrain
Colgrain is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. 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.
For site and facilities teams at buildings such as Hermitage Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
