Remedial sealant in Bonchurch, done properly
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint won’t last, however tidy it looks. We take it out and use a sealant made for that joint. We work on mouldy bath & shower sealant, failed movement joints and expansion joints, and people most often call us about caulk or the wrong sealant used in a wet area and thick, messy sealant smeared over tiles.
Somewhere as small as Bonchurch, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What remedial sealant looks like in Bonchurch
Bonchurch is within about 1 mile of 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. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Schools such as St Catherine's School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Shanklin station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Bonchurch is about 2 miles south of Shanklin, in the Isle of Wight. We provide remedial sealant to homes and businesses in Bonchurch and the surrounding area. Bonchurch is one of 125 places in the Isle of Wight we cover. For nearby work, see our Portsmouth page, about 15 miles away.

Bonchurch: your questions answered
Do you work for landlords with property near Shanklin 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’ll give you a fixed price before we start.
Do you take on hotel work around Bonchurch?
Yes, hotels and guest houses are among the places we work. Rooms can be done a few at a time, so the building stays open.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.
What if the leak isn’t the sealant?
That is why we look for the cause first. If the fault is elsewhere, you’ll know before any work is done.
How much does remedial sealant cost in Bonchurch?
It depends on the job, so we quote each one individually. To get one, ring 0345 464 0079 or email us with a short description of the job.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Is it messy?
We keep the work tidy. We protect what’s around the joints, and we clear up when we are done.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What happens on the day
Once we are on site, 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 for most joints, depending on how much old sealant has to come out. For a village or hamlet like Bonchurch, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Tell us about any water getting in
- Mention if the joints have been sealed before
- Clear items away from the joints we’re working on
Getting a quote

For landlords and businesses
If you manage several properties in or around Bonchurch, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
Hotels need rooms back in use, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Common problems we fix in Bonchurch
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, and the sealant lifts or goes mouldy from underneath.
Keep an eye out for any of the following:
- Sealant that came away because the surface wasn’t prepared
- Sealant applied over old sealant that has lifted
- Leaks that keep coming back after resealing
- Thick, messy sealant smeared over tiles
Homes close to Old St. Boniface Church include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

- What happens if the job turns out different

What affects the cost of remedial sealant
The price is agreed before any work begins. It’s based on:
- The number and length of the joints
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
Doing several joints on one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- Any previous sealing or DIY work
- The rough size of the job
- How we’d reach the joints
- A few pictures by email, if you can
Want a quote for remedial sealant? Please phone 0345 464 0079 or email us and tell us about the job. You’ll know what we plan to do, and what it will cost, before any work begins.
Looking after it afterwards
After the cure time, these simple habits help:
- Don’t wait for a small gap to become a leak
- Air the bathroom so the sealant can dry
- Don’t point over movement joints
- Check trays and worktops do not move
Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or send us an email.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
How the job changes by surface
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. Once it’s all removed, the joint is treated so the new sealant starts clean.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and tell you about any damage we find.
