Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
The process
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before we start. The work generally takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Great Stonar, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Move anything stored near the joints
- Mention any parking rules near the property
- Tell us about any water getting in

Why act early in Great Stonar
Repeat failures have a cause. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Older cottages and farmhouses around Great Stonar can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or send us an email.

When to call us in Great Stonar
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.
Look out for any of the following:
- Wide, uneven beads that look worse than the old ones
- Decorators’ caulk around a bath or shower
- Gaps opening along the back of the worktop
- Dark patches showing through the sealant
Rented homes near Sandwich station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before booking
- Which sealant they’ll use, and why
- Are they insured?
- Is VAT in the price?
- Whether all the old sealant comes out first

Questions from Great Stonar
Do you work in hotels near Great Stonar?
Yes, hospitality work, including hotels, is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.
Do you come to Great Stonar?
Yes. We cover Great Stonar, as part of our work across South East England, London and Scotland. To book, ring 0345 464 0079 or email us.
Someone sealed over the old bead. Can you fix it?
Yes. Both layers come out; over-sealing fails because silicone won’t bond to silicone.
My shower still leaks after a reseal. Can you sort it?
Yes, usually. We check it’s the sealant and not the tray, valve or waste, then strip and reseal the joints.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
How long will it take to strip and reseal the joint?
That depends on how many layers there are and how many joints. We will tell you before we start.
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Keep an eye on the ceiling below the bathroom
- Keep the room well ventilated
- Report a tray that rocks or a worktop that lifts
- Never seal over old silicone
If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Remedial sealant in Great Stonar: local notes
Great Stonar is within about 2 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Great Stonar has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room.
For site and facilities teams at buildings such as Sandwich Infant School, we reseal washrooms and kitchens in schools and businesses as well as homes. For an older house near a landmark such as St Mary's Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
