About our remedial sealant in Grahame Park
Two decades of sealant work means we recognise most failures quickly. We’re fully insured ARBOMaster approved applicators, and remedial work carries our 12-month guarantee. If you have sealant peeling off a dusty or damp surface and wide, uneven beads that look worse than the old ones, we can help.
In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Grahame Park are no different.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What remedial sealant looks like in Grahame Park
London has hard water, which leaves limescale on sealant, grout and taps. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early.
In the older streets around St Augustine Grahame Park, timber floors under older bathrooms flex, so joints need a sealant that moves with them. As a London address, Grahame Park can be tricky for parking: let us know about parking bays, permits or a driveway. For landlords with property near Mill Hill Broadway station, a joint that keeps failing is best fixed properly while the property is empty.

What we do, step by step
When we get to you, 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 a typical bath or shower, longer where several layers have been applied. In a London area like Grahame Park, 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.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- 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
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Use a soft cloth, not a scourer, on silicone
- Get the cause of a repeat leak found before resealing
- Act on a lifting corner right away
- Check ceilings under showers for marks
Give the new sealant its full cure time: normally around 24 hours, or as long as we advise.
A split movement joint lets rain into walls and floors, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
What affects the quote in Grahame Park
You will get a clear quote before we start. It’s based on:
- The number of rooms or windows
- The number and length of the joints
- Which sealant suits the joint
- Any mould that needs treating
The cost depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts.
Asking for a quote
When you contact us, these details help:
- If someone has resealed it before
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or send us an email.
When it isn’t the sealant
New sealant can’t fix everything, and we’ll tell you before any work starts. It won’t solve:
- Failed tanking or loose tiles behind the sealant
- A cracked shower tray or bath (that needs repair or replacing)
- A leaking trap, valve or supply pipe
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Expansion joints
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Shrunken worktop sealant
- Failed movement joints
Why act early in Grahame Park
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email.

Surface by surface
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before we reseal.
Grahame Park questions
I live in a flat in Grahame Park. Can a failed seal leak into the flat below?
Yes, it can. Water that gets past failed sealant or cracked grout can run under the bath or tray and show up on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Do you work in hotels near Grahame Park?
Yes, we work for hotels as well as homes and businesses. Rooms can be done a few at a time, so the building stays open.
Do you guarantee remedial jobs?
Yes, for 12 months. Where we’ve flagged another fault, it needs fixing for the joint to last.
Can old silicone be taken off without scratching the tiles?
Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.
Can I choose the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.
How long does the work take?
It takes a few hours for a typical bath or shower, longer where several layers have been applied. We will give you a timescale when we quote.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Do you work in Grahame Park?
We do. Grahame Park is part of the area we cover.
