DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
How we handle remedial sealant in Stonehills
The wrong product in the wrong joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. We work on expansion joints, leaking tray & enclosure joints and shrunken worktop sealant, and the jobs we see most are dark patches showing through the sealant and worktop sealant that has shrunk and split.
Being in a small place like Stonehills makes no difference to the job itself: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
Each job carries a 12-month guarantee, whatever its size.

Over-sealed & botched joints

How the visit works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere like Stonehills needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Clear the area around the work
- For business premises, tell us about site rules or sign-in

FAQs for Stonehills
Do you work in hotels near Stonehills?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
I let a flat near Hamble station. Can you help?
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 send us an email with the address and what needs doing, and we will give you a clear quote.
How long does the work take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.
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.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours for many products, and we’ll agree it with you first.
Can failed expansion joints be resealed?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Are you fully insured?
Yes, we are fully insured.
How long before the joint can be used?
It depends on the product. Before we leave, we will tell you the cure time.
Stonehills homes and their sealant
Stonehills is close to 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 Stonehills. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
Schools such as Fawley Infant 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 All Saints include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Never fill a movement joint with mortar or grout
- Check trays and worktops don’t move
- Use a soft cloth, not a scourer, on silicone
- Run the fan after every shower
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or email us.
Don’t keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
Why act early in Stonehills
Stripping out botched sealant adds time to a reseal, but not by much: it takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. Where a wall is exposed, as many are in small places like Stonehills, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
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. Call for a quick quote and we will go through it with you.

Common problems we fix in Stonehills
Sealant needs a clean, dry surface with no grease on it. Soap film, dust, damp or old residue stop it gripping, so it starts lifting sooner than it should.
These are the problems we’re asked about most:
- Caulk or the wrong sealant used in a wet area
- Sealant that came away because the surface wasn’t prepared
- Wide, uneven beads that look worse than the old ones
- Repeat leaks from the same joint
If you let a flat or house near Hamble station, botched sealant from a previous quick fix is easier to strip out between tenants.
