What the job involves on each surface
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning.
Remedial sealant in California
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all have to come out. We work on leaking tray & enclosure joints, expansion joints and failed movement joints, and people most often call us about leaks that keep coming back after resealing and over-sealed joints coming away.
Around California, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
Our work is backed for twelve months, in California and everywhere else we cover.

Common questions in California
Can you do remedial sealant in California?
Yes. We work across London and the South East, and California is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will send you a clear quote.
Is California within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses, and we are fully insured.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What should I tell you?
A short description and the location. We will ask anything else we need to know.
How long does the work take?
Allow a few hours, depending on how many layers have to come out. We will give you a timescale when we quote.
How much does remedial sealant cost in California?
Size, access and the old material all affect the cost. Ask us for a quote.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What affects the cost of remedial sealant
The quote reflects the job in front of us. We take into account:
- Whether there’s mould to deal with
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- How much there is to do
Combining jobs into one visit is generally more efficient than separate visits. We’ll send you a clear quote for the lot.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Bathrooms and kitchens in California
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as Gorse Ride Junior School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you let a flat or house near Crowthorne station, a joint that keeps failing is best fixed properly while the property is empty. Homes close to Church of St James include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Look for stains below bathrooms now and then
- Don’t point over movement joints
- Get the cause of a repeat leak found before resealing
- Have loose fittings fixed before resealing
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours, depending on how many layers have to come out, and the area is left clean. Somewhere as small as California, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- On commercial sites, let us know about site rules

Related advice
Why act early in California
Remedial work takes longer than a straight reseal, but not by much: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. In a small place like California, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
