Remedial sealant in Ashburton, done properly
Remedial jobs in Ashburton generally fall into a few patterns: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. If you have worktop sealant that has shrunk and split and sealant that came away because the surface wasn’t prepared, we can help, whatever the surface.
Hard London water leaves limescale on sealant, grout and taps alike. For a bathroom or kitchen in Ashburton, getting the joints right keeps water where it belongs and the room looking clean.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

What affects the quote in Ashburton
Some jobs are bigger than they look, and some smaller. The main factors:
- Access and height
- The number of rooms or windows
- The number and length of the joints
- Any working-time requirements on site
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
When you contact us, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- A few pictures by email, if you can
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Leave it or put it right?
Another bead over the top will not fix a failed joint. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Ashburton.
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

Common questions in Ashburton
Could a tired shower seal in my Ashburton flat affect the neighbours 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. It’s far simpler to replace tired sealant early than to deal with a neighbour’s ceiling.
Can you help a landlord with a rental near Norwood Junction station?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear quote.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available and agree one before work begins.
Can old silicone be taken off without scratching the tiles?
Yes, with care. The old bead is cut and lifted with tools that suit the surface, and the residue is cleaned away. We point out any damage that’s already there.
What if the leak isn’t the sealant?
We’ll tell you. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
What information do you need?
The location, the problem and the rough size of the job. Photos by email help too.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
When it isn’t the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Failed tanking or loose tiles behind the sealant
- Sealant in an older building that needs testing for asbestos first
- A tray or worktop that needs refixing first
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Where we work in Ashburton

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What remedial sealant looks like in Ashburton
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. London’s water is hard, so limescale builds up on sealant, grout and fittings.
For landlords with property near Norwood Junction station, a joint that keeps failing is best fixed properly while the property is empty. Ashburton is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For an older house near a landmark such as Church of St Luke, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

What the job involves on each surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out so the new sealant starts clean.
Looking after it afterwards
After the cure time, these simple habits help:
- Do not point over movement joints
- Find out why the sealant failed first
- Keep bleach and abrasives off the bead
- Never seal over old silicone
Where we’ve pointed out another fault, have it put right, or the new joint may fail again.
Don’t keep resealing the same joint. Have someone find out why, or the next bead will go the same way.
What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours, depending on how many layers have to come out. In Ashburton, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
