Remedial sealant in Lee-on-the-Solent, done properly
Movement and expansion joints fail when the sealant cannot stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you have products that weren’t meant for the joint and a shower that leaks however often it’s resealed, we can put it right, on mouldy bath & shower sealant, shrunken worktop sealant and failed movement joints alike.
In a smaller place like Lee-on-the-Solent, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
Each job carries a 12-month guarantee.

What happens on the day
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most joints, depending on how much old sealant has to come out and we leave things clean and tidy. For a job in Lee-on-the-Solent, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
DIY sealant or a professional job?
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 does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Lee-on-the-Solent questions
Will you come out to Lee-on-the-Solent?

Can you help a landlord with a rental near Fareham station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.

Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Can you remove sealant that’s been put over old sealant?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s what makes the new bead last.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, so we find that first.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.

Quotes for remedial sealant in Lee-on-the-Solent
We quote each job individually. These are the things that affect it:
- Access and height
- Which sealant suits the joint
- The old material and how stubborn it is
- How much there is to do
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- A few photos by email, if you can
- What’s wrong with the joints now
- Where the property is
- If it’s domestic, commercial or a hotel
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.
How to look after the new joints
Looking after new joints is easy:
- Report a tray that rocks or a worktop that lifts
- Run the fan after every shower
- Act on a lifting corner straight away
- Look for stains below bathrooms now and then
Keep the room ventilated: run the fan during and after showers, or open a window.
Movement joints that have split let water into the structure, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.
What remedial sealant looks like in Lee-on-the-Solent
Lee-on-the-Solent is close to 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. Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Letting a property close to Fareham station? Then botched sealant from a previous quick fix is easier to strip out between tenants. Schools such as Lee-On-the-Solent Infant and Nursery School are buildings too, and 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. Homes close to Church of St Faith include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Why deal with it now?
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. In a smaller place like Lee-on-the-Solent, 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.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
