Remedial Sealant in Edgware
Problem with your failed sealant joints in Edgware? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Movement joints that have split or pulled away
- Mould trapped under a layer of silicone
- Sealant that came away because the surface wasn’t prepared
Can I do it myself?
If you are 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 fails, we can still redo it.
A careful DIYer can reseal a simple joint, 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.
Remedial sealant in Edgware
The wrong product in the wrong joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. If you are dealing with thick, messy sealant smeared over tiles and sealant that came away because the surface wasn’t prepared, we can help, on botched or over-sealed joints, shrunken worktop sealant and failed movement joints alike.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Edgware, getting the joints right keeps water where it belongs and the room looking clean.
Each job carries a 12-month guarantee, large or small.

Your questions about remedial sealant in Edgware
Do you work for landlords with property near Mill Hill Broadway station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
I live in a flat in Edgware. Can a failed seal leak into the flat below?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
How long does remedial resealing take?
Allow a few hours, depending on how many layers have to come out. You’ll know the timing when we quote.
My shower still leaks after a reseal. Can you sort it?
Yes. We’ll take all the sealant out, look for why it failed and reseal it properly.

What to tell us for a quote
Before you ask for a quote, have a think about:
- Where the property is
- The rough size of the job
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
Work for landlords, hotels and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A tray or bath that is cracked
- Water damage behind tiles that needs a tiler
- A tray or worktop that needs refixing first
If in doubt, ring 0345 464 0079 or email us and we will say what we think.
Joints and surfaces we work on
- Mouldy bath & shower sealant
- Leaking tray & enclosure joints
- Expansion joints
- Failed movement joints
- Botched or over-sealed joints
- Shrunken worktop sealant
Surface by surface
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. We check both before we reseal.
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.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check ceilings under showers for marks
- Do not point over movement joints
- Clean sealant with mild products only
- Get the cause of a repeat leak found before resealing
Don’t let anyone seal over it later. New silicone doesn’t bond to old.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into whatever is behind or below. Sorting it early limits the damage.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes a few hours, depending on how many layers have to come out, including the tidy-up. In a London area like Edgware, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property

What remedial sealant looks like in Edgware
London’s water is hard, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
