Bathroom resealing in New Southgate, done properly
Showers work their sealant harder than baths. Trays, enclosures, screen profiles and wet room floors all need a flexible, waterproof seal. They’re resealed with anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. If you are dealing with water getting behind the kitchen upstand and sealant that has split, shrunk or peeled away, we can help.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. A compact bathroom that steams up every day is hard on silicone and grout, and homes in New Southgate are no different.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Why act early in New Southgate
Mould removers can fade the surface of a stained bead, but mould that has grown into the sealant tends to return. The lasting answer is to remove the bead and start again. In a flat in New Southgate, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

Surface by surface
Kitchen worktops & upstands
Worktop joints get wet and wiped every day. The new bead is colour-matched where it shows, so the line doesn’t stand out.
Wet rooms
A wet room floor and its walls can move independently, so the corners need a flexible seal, not grout. Cracked grout in a corner can be cut out and replaced with silicone.
Common questions in New Southgate
I let a flat near New Southgate station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is parking a problem for a job in New Southgate?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Does the resealing come with a guarantee?
Yes. All our work comes with a 12-month guarantee, and we are fully insured.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can you reseal around my kitchen sink and worktop?
Yes. We reseal worktop upstands, sinks and splashbacks, with a sealant suited to kitchens, colour-matched where it shows.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is it OK to put new sealant on top of the old bead?
No. New silicone will not bond to old silicone, so it peels away and hides mould and water. We always take the old sealant out completely.
Bathroom resealing around New Southgate
New Southgate has hotels and guest accommodation nearby. Hotel bathrooms are part of our work as well as homes, and can be done room by room. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
New Southgate is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. In the older streets around St Paul's Church, walls and floors in older homes can move, and sealant and grout show it first.

Landlord and commercial work in New Southgate
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes two to three hours for a typical bath, depending on how much old sealant there is. In a London area like New Southgate, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We protect the area and cut out all of the old sealant, including the film left on the tiles.
- The joint is cleaned, degreased and treated for mould.
- The joint is left to dry, and baths are filled with water first.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- We tidy up and give you the cure time, usually around 24 hours.
Preparing for the visit
- Tell us about any water getting in
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

What we are called out for in New Southgate
Mould is the reason many people want their sealant replaced. Steamy rooms that do not dry out keep the silicone damp for hours, and once it has grown into the bead, cleaning rarely gets it out.
Any of these means the joints need attention:
- Water getting behind the kitchen upstand
- A messy, uneven bead from a previous reseal
- Two layers of silicone, both failing
- Water escaping at the shower enclosure
If you let a flat or house near New Southgate station, a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
How we quote for bathroom resealing
Jobs vary more than people expect. What affects the quote:
- The old material and how stubborn it is
- Access and height
- Whether there’s mould to deal with
- The number and length of the joints
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- Where the property is
- Any previous sealing or DIY work
- The type of property
We do not publish a price list. Instead, your job gets its own clear quote. To arrange one, call 0345 464 0079 or email us.
