About our remedial sealant in Wherwell
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 need stripping out. We work on botched or over-sealed joints, shrunken worktop sealant and leaking tray & enclosure joints, and common reasons people get in touch are floor or wall movement joints that have failed and products that weren’t meant for the joint.
Somewhere as small as Wherwell, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Each job carries a 12-month guarantee.

Quotes for remedial sealant in Wherwell
There’s no set price list. The quote depends on:
- How easy the joints are to reach
- Mould in or behind the old joints
- The type of sealant required
- The number and length of the joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- A few photos by email, if you can
- If it’s domestic, commercial or a hotel
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved before giving you a price.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. Somewhere like Wherwell needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking the joint for movement, leaks and the reason it failed.
- 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.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- Plan for the work area to be out of bounds to pets and children
- Mention any sign-in or site rules at work premises
- Clear the area around the work

Why act early in Wherwell
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. Around Wherwell, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Why us?
- White, clear, grey or another colour, product permitting
- Anti-fungal silicone where joints get wet
- Colour picked to suit the job
- Rated 4.9 stars on Google

Aftercare tips
Aftercare is simple:
- Don’t point over movement joints
- Check ceilings under showers for marks
- Use a soft cloth, not a scourer, on silicone
- Keep the room well ventilated
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.
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.
Common questions in Wherwell
Do you work for landlords with property near Andover station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Is Wherwell within the area you cover?
Yes. Wherwell is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
How long does the work take?
A little longer than a standard reseal. Most jobs take a few hours, and we confirm the time with your quote.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
Signs you need remedial sealant in Wherwell
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
Keep an eye out for any of the following:
- Leaks that keep coming back after resealing
- Beads that never stuck properly
- Gaps opening along the back of the worktop
- Movement joints that have split or pulled away
For an older house near a landmark such as Church of St Peter and Holy Cross, walls and floors in older homes can move, and sealant and grout show it first.

Remedial sealant in Wherwell: local notes
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

For site and facilities teams at buildings such as Wherwell Primary School, 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.
