What affects the quote in Liss
Every job gets its own quote. This is what makes a difference:
- The old material and how stubborn it is
- Any mould that needs treating
- How much there is to do
- Whether the work is at height
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 explain what it covers.
Asking for a quote
Before you ask for a quote, have a think about:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.
Remedial sealant in Liss
Some sealant jobs aren’t a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out. We work on mouldy bath & shower sealant, shrunken worktop sealant and failed movement joints, and people most often call us about smears and lumps from a botched reseal and decorators’ caulk around a bath or shower.
Even in a smaller place like Liss, bathrooms and kitchens see heavy daily use. Older or newer, every room gets the same approach: all the old material out, the joint cleaned and dried, then new sealant or grout.
There’s a 12-month guarantee on every job.

Why act early in Liss
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful stripping is where most of our time goes. Around Liss, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

How the job changes by surface
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. 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.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Water damage behind tiles that needs a tiler
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Botched or over-sealed joints
- Expansion joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Common problems we fix in Liss
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Common reasons people contact us are:
- Wide, uneven beads that look worse than the old ones
- Sealant that came away because the surface wasn’t prepared
- Leaks that keep coming back after resealing
- Movement joints that have split or pulled away
For an older house near a landmark such as Church of St Mary, walls and floors in older homes can move, and sealant and grout show it first.

Remedial sealant around Liss
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Liss has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Rented homes near Liss station change hands often, and a joint that keeps failing is best fixed properly while the property is empty. Managing a site like Liss Infant School? Then 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.

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. For a job in Liss, 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.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

Common questions in Liss
Will you come out to Liss?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for hotels and guest houses in Liss?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
How do I get a quote for remedial sealant in Liss?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you take off two layers of silicone?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
