About our remedial sealant in North Street
Getting old sealant out properly is slow, careful work. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. If you have a second bead peeling off the first and torn expansion joints, we can put it right.
Homes around North Street are mostly houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
We stand behind the work with a one-year guarantee, so you are covered after we have gone.

FAQs for North Street
Is North Street in your area for remedial sealant?
Yes. We work across London and the South East, and North Street is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
What guarantee comes with remedial sealant in North Street?
All our work, in North Street and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. Repeat leaks normally come from over-sealing, movement or water getting in elsewhere, so we find that first.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
What should I tell you?
Only a few details: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or email us.

Why deal with it now?
Spraying mould remover on a sealed-over joint does not reach what’s underneath. Removal is the only way to get at it, and the joint treated and dried before resealing. Around North Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.

North Street homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of St Peter, walls and floors in older homes can move, and sealant and grout show it first.

When to call us in North Street
Some joints fail because water is reaching them from behind. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
These are the problems we’re asked about most:
- Dark patches showing through the sealant
- Sealant that came away because the surface wasn’t prepared
- Caulk or the wrong sealant used in a wet area
- Worktop sealant that has shrunk and split
If you look after a building such as Ropley Church of England Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as North Street, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Let us know about parking restrictions
- Tell us about access, such as stairs, a lift or high-level joints
- Move anything stored near the joints

Advice
What sealant work cannot fix
We’ll always be straight with you, so here’s what sealant cannot fix:
- A tray or worktop that needs refixing first
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A leaking trap, valve or supply pipe
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.
What we seal
- Expansion joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Failed movement joints
How the job changes by surface
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We will tell you what we find.
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath, then reseal neatly.
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
