Bathroom resealing in Portsmouth Point, done properly
Showers work their sealant harder than baths. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. They’re resealed with anti-fungal sanitary silicone, tooled smooth so water runs off instead of sitting in a ridge. We work on shower trays & enclosures, basins & vanity units and kitchen worktops & upstands, and the jobs we see most are gaps where the bath or tray has moved and gaps between the worktop and the wall.
Homes around Portsmouth Point range from older cottages to more recent houses. In older homes, walls and floors can move a little more, so the right flexible sealant matters.
All of our work is guaranteed for twelve months.

Why it’s worth doing now in Portsmouth Point
Dealing with sealant early is a short job: it takes a couple of hours for a single bath or shower. Wait for a leak and you may be looking at panels off, drying out and redecorating too. In a smaller place like Portsmouth Point, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Bathroom resealing in Portsmouth Point: local notes
Portsmouth Point 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. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
Letting a property close to Portsmouth Harbour station? Then a reseal between tenants is a quick way to make the bathroom and kitchen look cared for. If you live in an older home near Portsmouth Garrison church, walls and floors in older homes can move, and sealant and grout show it first.
Portsmouth Point is about 2 miles west of Southsea, in Portsmouth. Jobs in Portsmouth Point get the same care as everywhere else we work: old sealant removed completely, careful preparation and a 12-month guarantee. 19 places in Portsmouth are on our list, large and small.

Questions from Portsmouth Point
I let a flat near Portsmouth Harbour station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you take on hotel work around Portsmouth Point?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Are you fully insured?
Yes. Mr Mastic is fully insured.
My sealant has gone black. Can you sort it?
Yes, we replace the mouldy bead. Cleaning products may lighten it, but the lasting fix is new anti-fungal silicone on a clean, treated joint. Good ventilation helps keep it away.
How long does it take to reseal a bath or shower?
It takes half a day or less for one room, longer when the kitchen is included. You will know how long to expect before we start.
How do I get a quote for bathroom resealing in Portsmouth Point?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or send us an email with a short description of the job.
Do you do kitchens as well as bathrooms?
Yes. Worktops, sinks and splashbacks are all part of the job, in a kitchen-suitable sealant, matched to the worktop where it’s on show.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you are 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.
When to call us in Portsmouth Point
Silicone does not last for ever. Daily water, heat and cleaning products take their toll over the years, so its life depends on how the room is used, cleaned and aired.
Common reasons people contact us are:
- Gaps where the bath or tray has moved
- Damp behind the bath or under the tray
- Smears of silicone across the tiles
- Leaking joints on a shower screen
Schools such as St Jude's CofE Primary School are buildings too, and washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

Aftercare tips
Looking after new joints is easy:
- Avoid abrasive pads on the sealant
- Wipe up water along the back of the worktop
- Move toiletries away from the joint
- Open a window or run the fan so the room dries
Wipe up standing water along the worktop joint and keep hot pans off the bead. The drier the joint stays, the longer it lasts.
Watch for the early signs: lifting ends, gaps, dark shadows under the bead or a stain downstairs. If you spot one, it’s time to reseal.
How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes around two hours for one bath or shower, longer for a whole bathroom. In a smaller place like Portsmouth Point, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First the area is protected and every bit of old sealant removed.
- We clean and degrease the joint and treat any mould.
- We let it dry fully and fill the bath with water before sealing.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We clear away and tell you when it can get wet, normally after around 24 hours.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Clear the area around the work
- Plan for the work area to be out of bounds to pets and children
