Bathroom resealing for homes and businesses in Portchester
A reseal only lasts if the joint is properly prepared. The old sealant is removed to the last smear, then the joint is cleaned, degreased and treated for mould. Only once it’s dry does the new bead go on. Common call-outs are for shrunken sealant along the back of a worktop and lumpy, uneven sealant from a DIY attempt, on shower trays & enclosures, kitchen worktops & upstands and wet rooms.
In a smaller place like Portchester, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Portchester homes and their sealant
Portchester is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, and sealant and grout that work that hard wear out sooner. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you live in an older home near Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first. Schools such as Castle Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a couple of hours for a single bath or shower and we leave things clean and tidy. A visit to Portchester is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint first and check for movement or leaks.
- The old silicone is cut out completely, along with the film it leaves on the tiles.
- Joints are degreased and any mould is treated.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- We tool the bead to a neat finish and give you the cure time, usually around 24 hours.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises

Advice
Why act early in Portchester
You do not need a new bathroom because the sealant looks bad. A new bead often brings the whole room back, as long as the fittings themselves are sound. If something else is wrong, we will tell you. Homes in smaller places like Portchester can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

Portchester: your questions answered
Can you do bathroom resealing in Portchester?
Yes, Portchester is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Can you help a landlord with a rental near Portchester station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
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.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
How long before the new sealant can get wet?
Silicone is touch-dry quite quickly, but it takes longer to cure. Keep water off it for around 24 hours, or follow the cure time we give you.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Is white the only colour available?
We can use white, clear or a colour to suit. On a worktop we colour-match where the joint shows.
How the job changes by surface
Sinks & splashbacks
Where a splashback meets the worktop, there’s a joint that catches every splash. We renew it in clear, white or a matched colour.
Shower trays & enclosures
Shower trays are sealed to the wall, and enclosures are sealed to the tray and tiles. Both get soaked every time the shower runs, so each is cut out and renewed with anti-fungal sanitary silicone.
Do you need bathroom resealing in Portchester?
Silicone does not last for ever. Daily water, heat and cleaning products take their toll over the years, and how long it lasts comes down to use, cleaning and ventilation.
The most common problems we see are:
- Gaps where the bath or tray has moved
- Black mould in the silicone that won’t clean off
- Sealant that has split, shrunk or peeled away
- Leaks into the floor or ceiling below
Letting a property close to Portchester station? Then fresh sealant around the bath, shower and sink between tenancies helps a property present well and keeps leaks at bay.
