Langstone: your questions answered
Can you help a landlord with a rental near Havant station?
Yes, we work for letting agents and landlords. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Langstone within the area you cover?
Yes, Langstone is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do I need to be at home?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
How long before the new sealant can get wet?
The surface skins over fairly quickly, but the bead needs longer to cure right through. Keep water off it for around 24 hours, or as long as we advise for that product.
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.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so any old material comes out before anything new goes in.
Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
What should I tell you?
Tell us what needs doing and where, plus photos if you have them. We will ask anything else we need to know.
How we handle bathroom resealing in Langstone
Homes in Langstone have the same weak spots as anywhere else: bath edges, tray joints, basin backs and kitchen upstands. Each one is stripped, cleaned and dried before new silicone goes in. We’re often asked to deal with black spots spreading through the bead and lumpy, uneven sealant from a DIY attempt, across wet rooms, kitchen worktops & upstands and shower trays & enclosures.
Somewhere as small as Langstone, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
A 12-month guarantee comes as standard.

What affects the quote in Langstone
We don’t publish a price list, because jobs vary so much. The quote depends on:
- Mould in or behind the old joints
- Whether old sealant or filler has to be cut out
- The number of rooms or windows
- Any working-time requirements on site
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- If someone has resealed it before
- How we’d reach the joints
- The address or postcode of the job
Quotes start with a quick conversation. Describe the problem, the location and the size of the job. When it suits you, phone 0345 464 0079 or send us an email.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Run the extractor fan during and after every shower
- Dry the bead with a towel now and then
- Wipe up water along the back of the worktop
- Avoid abrasive pads on the sealant
Don’t stand bottles along the bead, as they hold water against it. Squeegeeing the walls and tray after use helps the joint dry.
Small signs come before a leak: lifting ends, gaps, dark shadows under the bead or a stain downstairs. Any of these means the joint needs attention.
Why deal with it now?
Mould removers can fade the surface of a stained bead, but where mould is inside the silicone it generally comes back. The lasting answer is to remove the bead and start again. Older cottages and farmhouses around Langstone can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

Signs you need bathroom resealing in Langstone
Sealing over old silicone is one of the commonest mistakes we find. New silicone won’t bond to old silicone, so it lifts, lets water in and traps mould underneath.
Look out for these signs:
- Leaks into the floor or ceiling below
- Sealant that has split, shrunk or peeled away
- Two layers of silicone, both failing
- Gaps between the worktop and the wall
Schools such as Bosmere Junior School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What the job involves on each surface
Shower trays & enclosures
A tray that rocks will split any sealant. We check for movement before we reseal, and if the tray needs refixing, we’ll say so.
Basins & vanity units
Basins take less water than showers, but the joint behind them is splashed every day. Corners behind basins are where mould tends to start, so it’s cut out and renewed just like a bath joint.
Bathroom resealing in Langstone: local notes
Langstone is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
For landlords with property near Havant station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. Homes close to Saint Nicholas' Chapel include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Everything for the job comes with us, so a second trip is avoided where possible.
- We start by protecting the area and stripping out the old bead, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- We let it dry fully and fill the bath with water before sealing.
- 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, usually after around 24 hours.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
