Hursley Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for homes and businesses in Hursley and across Hampshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Products that weren’t meant for the joint
- Thick, messy sealant smeared over tiles
- Black mould underneath the bead
Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep movement joints clear of mortar and paint
- Never seal over old silicone
- Have loose fittings fixed before resealing
- Keep bleach and abrasives off the bead
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old, so the old bead should always come out first.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
How we handle remedial sealant in Hursley
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. Common call-outs are for decorators’ caulk around a bath or shower and smears and lumps from a botched reseal, across leaking tray & enclosure joints, mouldy bath & shower sealant and expansion joints.
Somewhere as small as Hursley, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or email us.

How we quote for remedial sealant
We quote each job individually. These are the things that affect it:
- Whether old sealant or filler has to be cut out
- The type of sealant required
- Access and height
- Any working-time requirements on site
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or send us an email for an honest opinion and a quote.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- What’s wrong with the joints now
- The address or postcode of the job
- If it’s domestic, commercial or a hotel
- The rough size of the job
For remedial sealant in Hursley, ring 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and you will get a clear quote before work begins.
Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Different surfaces, different methods
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. We strip it, degrease the joint and reseal in a colour to suit.
Leaking trays & enclosures
If the tray is cracked, or the leak is from the valve or waste, sealant will not fix it. We say so rather than reseal.
What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. Somewhere like Hursley needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children

Hursley homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
In the older streets around Church of All Saints, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For site and facilities teams at buildings such as John Keble Church of England 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.
Hursley is about 3 miles north of Chandler's Ford, in Hampshire. Anywhere in SO21, our applicators can take on remedial sealant. Our Hampshire coverage runs to 683 places, and Hursley is one of them. Southampton is on our list too, around 7 miles away.

Questions from Hursley
Can you help a landlord with a rental near Shawford station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Hursley in your area for remedial sealant?
Yes, Hursley is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you when we finish.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
Can you remove old sealant without damaging the bath?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. We point out any damage that is already there.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we’re using and why.
What sealant work cannot fix
We will not take on work that will not last, so here’s what sealant can’t put right:
- Water damage behind tiles that needs a tiler
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Older mastics that may need an asbestos check before removal
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think before booking.
What we seal
- Expansion joints
- Failed movement joints
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Shrunken worktop sealant
What we’re called out for in Hursley
A lot of failed joints have been sealed over rather than replaced. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.
Common reasons people contact us are:
- Smears and lumps from a botched reseal
- Caulk or the wrong sealant used in a wet area
- Sealant applied over old sealant that has lifted
- Gaps opening along the back of the worktop
Rented homes near Shawford station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.
