Bathroom Resealing in Copnor
Professional bathroom resealing in and around Copnor, with old sealant always removed completely and a one-year guarantee.
- Splits where the tray meets the wall
- Mouldy sealant that has gone black
- Gaps between the worktop and the wall
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen. Parking around Copnor is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- The joint is left to dry, and baths are filled with water first.
- New anti-fungal silicone goes on in a colour to suit and is tooled to a clean finish.
- We clear away and tell you when it can get wet, generally after around 24 hours.
How to prepare
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Let us know about parking restrictions

Bathroom resealing in Copnor, done properly
Across Copnor, the joints we reseal are the ones that fail in any home: the long edge of the bath, the base of the shower tray, the back of the basin and the line along the worktop. Each one is stripped, cleaned and dried before new silicone goes in. Typical jobs include leaks into the floor or ceiling below and cracked, shrunken or lifting silicone, on sinks & splashbacks, shower trays & enclosures and wet rooms.
Even in a smaller place like Copnor, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Leave it or put it right?
Sorting it now is quick: the work takes a morning or an afternoon for most single baths and showers. Wait for a leak and you may be looking at panels off, drying out and redecorating too. Around Copnor, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Looking after it afterwards
Looking after new joints is easy:
- Keep an eye on the corners, where splits start
- Clean with a mild bathroom cleaner and a soft cloth
- Wipe up water along the back of the worktop
- Squeegee the walls and tray after use
Good ventilation does more than any cleaner. Run the extractor fan during and after a shower, so the silicone gets a chance to dry.
Each shower pushes a little more water through a failed joint. Over time that water reaches floors, walls and ceilings. Early resealing closes the gap before damage is done.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What bathroom resealing looks like in Copnor
Copnor is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Copnor has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For landlords with property near Fratton station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. If you look after a building such as Westover Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Questions from Copnor
Do you work for landlords with property near Fratton station?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do you work in hotels near Copnor?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
What does bathroom resealing cost?
It depends on the job, so we quote each one individually. For a quick quote, call 0345 464 0079 or email us and let us know what needs doing and where.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can mouldy silicone be sorted out?
Yes, by replacing the sealant. Sprays can fade the marks, but cutting it out and resealing is what lasts. Good ventilation helps keep it away.
When can I use the bath or shower again?
Around 24 hours is typical, and we confirm the time for the product used. Getting it wet too early can spoil the new joint.
Is white the only colour available?
White, clear and a range of colours are available. Where the joint is on show, we match it to the surface.

Signs you need bathroom resealing in Copnor
A bath shifts a little every time it’s filled and emptied. An acrylic bath flexes under load, while a poorly supported tray can shift underfoot. Over time the joint tears or pulls away from the tile.
Keep an eye out for these signs:
- A reseal done over the top of the old bead
- Mouldy sealant that has gone black
- Smears of silicone across the tiles
- Water getting behind the bath panel
In the older streets around Church of St Alban, older homes can move a little, which is hard on rigid grout and tired sealant.
Questions to ask before booking
- Whether you can choose the colour
- Is the old sealant removed completely?
- How much experience the applicator has
- Whether they’re fully insured
