How we handle remedial sealant in Aldwick
Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we’ll tell you rather than reseal something that won’t fix it. We work on botched or over-sealed joints, shrunken worktop sealant and mouldy bath & shower sealant, and common reasons people get in touch are mould trapped under a layer of silicone and leaks that keep coming back after resealing.
Homes around Aldwick range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.
Big or small, it’s backed by our 12-month guarantee.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours, depending on how many layers have to come out. A visit to Aldwick is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

Related advice
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Do not add new sealant on top of old
- Don’t wait for a small gap to become a leak
- Never fill a movement joint with mortar or grout
- Find out why the sealant failed first
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
How we quote for remedial sealant
The price is agreed before any work begins. It takes into account:
- Whether the work is at height
- How much there is to do
- The type of sealant required
- Whether there’s mould to deal with
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
Helping us quote
Before you ask for a quote, have a think about:
- The type of property
- Any previous sealing or DIY work
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand.
Bathrooms and kitchens in Aldwick
Aldwick 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. There are hotels and other places to stay in and around Aldwick. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For site and facilities teams at buildings such as Nyewood CofE Junior School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St Richard’s Church, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near Bognor Regis station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

FAQs for Aldwick
Do you cover smaller places like Aldwick?
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.

Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
What if resealing won’t fix my leak?
You’ll hear it from us. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, so we won’t pretend it will.
Can you take off two layers of silicone?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. All the sealant comes out, we find out why it failed, and the joint is resealed properly.
Where are you based?

Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Why deal with it now?
Stripping out botched sealant adds time to a reseal, but rarely a lot: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Homes in smaller places like Aldwick 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.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
