- A second bead peeling off the first
- Sealant peeling off a dusty or damp surface
- Dark patches showing through the sealant
What the job involves on each surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler can’t move. Where it can be raked out, we replace it with flexible sealant.
Over-sealed & botched joints
Every layer has to come out, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Remedial sealant for homes and businesses in The Hyde
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. We work on failed movement joints, botched or over-sealed joints and shrunken worktop sealant, and people most often call us about over-sealed joints coming away and smears and lumps from a botched reseal.
London homes include a lot of flats, conversions and mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in The Hyde more than a cosmetic job.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Check ceilings under showers for marks
- Find out why the sealant failed first
- Never fill a movement joint with mortar or grout
- Don’t add new sealant on top of old
Ventilation keeps mould away from the new bead: use the extractor or open a window after showering.
Don’t keep resealing the same joint. Have someone find out why, otherwise the next attempt will fail too.
What affects the quote in The Hyde
The price is agreed before any work begins. It takes into account:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Any working-time requirements on site
- The type of sealant required
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.
Helping us quote
There’s no need for technical detail. Just tell us:
- Roughly how big the job is
- The problem you’ve noticed
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you are ready, phone 0345 464 0079 or drop us an email.
Places near The Hyde

Remedial sealant around The Hyde
There are hotels and other places to stay in and around The Hyde. Hotel bathrooms are part of our work as well as homes, and can be done room by room. London’s water is hard, which leaves limescale on sealant, grout and taps.
The Hyde is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Hendon station? Then a joint that keeps failing is best fixed properly while the property is empty.

Why it’s worth doing now in The Hyde
Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in The Hyde, the repair is bigger than a sealant job.

What happens on the day
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours, depending on how many layers have to come out. In a London area like The Hyde, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.

Common questions in The Hyde
Do you take on hotel work around The Hyde?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Is parking a problem for a job in The Hyde?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Where are you based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Can you take off two layers of silicone?
Yes. We remove every layer; new silicone doesn’t bond to old silicone, which is why over-sealing fails.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Signs you need remedial sealant in The Hyde
One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the top layer lifts and water and mould collect between the two.
Keep an eye out for any of the following:
- Beads that never stuck properly
- Mould trapped under a layer of silicone
- Floor or wall movement joints that have failed
- Worktop sealant that has shrunk and split
Managing a site like The Hyde School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before you book
- What guarantee comes with the work
- How much experience the applicator has
- Is VAT in the price?
- Whether you can choose the colour
Honest limits
A few problems are outside what sealant work can do:
- Movement from fittings that aren’t supported
- A cracked shower tray or bath (that needs repair or replacing)
- Water damage behind tiles that needs a tiler
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
