How we handle remedial sealant in Cannon's Green
With more than 20 years’ experience, our applicators have seen most of the ways sealant can fail. We’re fully insured ARBOMaster approved applicators, and every remedial job comes with a 12-month guarantee. If you are dealing with smears and lumps from a botched reseal and worktop sealant that has shrunk and split, we can help, on shrunken worktop sealant, failed movement joints and expansion joints alike.
Around Cannon's Green, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Signs you need remedial sealant in Cannon's Green
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould. At that point it has to come out.
If you can see any of these, it’s time to have the joints looked at:
- Dark patches showing through the sealant
- Over-sealed joints coming away
- Products that weren’t meant for the joint
- Movement joints that have split or pulled away
Managing a site like The Ongar Academy? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Report a tray that rocks or a worktop that lifts
- Keep an eye on the ceiling below the bathroom
- Never fill a movement joint with mortar or grout
- Air the bathroom so the sealant can dry
Keep an eye on the joint at first, particularly where the original failure was caused by movement. Should anything change, 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.
Questions from Cannon's Green
Is Cannon's Green within the area you cover?
Yes, Cannon's Green is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Is Cannon's Green in your area for remedial sealant?
Yes. Our work covers London and the South East, and Cannon's Green is part of that. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Can you fix a reseal that hasn’t worked?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
What if the leak isn’t the sealant?
In that case, we tell you what we have found. A plumber or fitter may be needed.
Do you fix expansion and movement joints?
Yes. Backing sets the depth and stops the sealant sticking to the back.
Can you strip sealant from an acrylic tray safely?
Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

What happens on the day
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Cannon's Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- 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.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Clear items away from the joints we are working on

- Tell us about access, such as stairs, a lift or high-level joints

Advice
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
We work for landlords and agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Cannon's Green homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Homes close to Church of St Nicholas include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

What affects the cost of remedial sealant
For a quick quote, just ask. The main things that affect it are:
- How easy the joints are to reach
- Any working-time requirements on site
- The size of the job
- Whether there’s mould to deal with
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Helping us quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- Photos by email, if that’s easy
- Whether it has been sealed before
- Whether it’s a home or a business
To get a quote, phone 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
Why it’s worth doing now in Cannon's Green
Another bead over the top will not fix a failed joint. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. Where a wall is exposed, as many are in small places like Cannon's Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or send us an email and we will talk you through it.
