Deadwater Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for homes and businesses in Deadwater and across Hampshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Repeat leaks from the same joint
- Caulk or the wrong sealant used in a wet area
- Sealant applied over old sealant that has lifted
Why deal with it now?
Ripping out a bathroom isn’t normally needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we’ll tell you. In a smaller place like Deadwater, 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 is usually more efficient than separate visits. We will give you a clear price for the lot.
Why us?
- Anti-fungal silicone where joints get wet
- Neat joints and a tidy finish
- Colour picked to suit the job
- Over 20 years’ experience

About our remedial sealant in Deadwater
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we’ll tell you rather than reseal something that won’t fix it. We work on expansion joints, failed movement joints and leaking tray & enclosure joints, and the jobs we see most are dark patches showing through the sealant and leaks that keep coming back after resealing.
In a smaller place like Deadwater, homes are mostly houses and bungalows rather than flats, from older cottages to newer builds. Sealant and grout wear out here just as they do in a big town.
All our work is covered by our one-year guarantee.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How the job changes by surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Mouldy bath & shower sealant
Black mould inside the bead won’t scrub out. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.

Deadwater questions
Will you come out to Deadwater?
Yes. Deadwater is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Liphook station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
Where are you based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
What if resealing will not fix my leak?
In that case, we tell you what we’ve found. You may need a plumber or bathroom fitter before any new sealant goes on.
Can you reseal a split movement joint?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or send us an email.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Common problems we fix in Deadwater
Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. At that point it has to come out.
People normally contact us after spotting something like this:
- Leaks that keep coming back after resealing
- Beads that never stuck properly
- Mould trapped under a layer of silicone
- Worktop sealant that has shrunk and split
Homes close to St Mark's Sacred Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Bathrooms and kitchens in Deadwater
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Letting a property close to Liphook station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. Managing a site like Mill Chase Academy? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

The process
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a job in Deadwater, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can

What affects the cost of remedial sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of rooms or windows
- The old material and how stubborn it is
- Working hours on commercial sites
- Access and height
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us and we’ll give you an honest view and a quote.
Asking for a quote
Photos help, but a description is a good start. Please mention:
- Where the property is
- Roughly how big the job is
- A few pictures by email, if you can
- The problem you’ve noticed
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use a soft cloth, not a scourer, on silicone
- Check ceilings under showers for marks
- Don’t wait for a small gap to become a leak
- Air the bathroom so the sealant can dry
If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.
