DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Remedial sealant in Barnes
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out. If you have over-sealed joints coming away and dark patches showing through the sealant, we can put it right, on botched or over-sealed joints, shrunken worktop sealant and leaking tray & enclosure joints alike.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Barnes are no different.
All of our work is guaranteed for twelve months.

Can you reseal a split movement joint?

What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.

Yes. We cut out all the old sealant and clean the joint.
Can old silicone be taken off without scratching the tiles?
Yes. We take our time over removal, particularly on softer surfaces like acrylic.
Barnes homes and their sealant
In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London’s water is hard, so limescale builds up on sealant, grout and fittings.
If you look after a building such as St Osmund's Catholic 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. Barnes is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Looking after it afterwards
After the cure time, these simple habits help:
- Use a soft cloth, not a scourer, on silicone
- Do not point over movement joints
- Keep the room well ventilated
- Find out why the sealant failed first
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Do you need remedial sealant in Barnes?
Using the wrong product is a common cause: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. Each fails in its own way.
It’s worth asking for a quote if you see:
- Sealant applied over old sealant that has lifted
- Kitchen joints letting water behind the worktop
- Thick, messy sealant smeared over tiles
- Decorators’ caulk around a bath or shower
If you live in an older home near Barnes Methodist Church, walls and floors in older homes can move, and sealant and grout show it first.

How we quote for remedial sealant
Every job gets its own quote. These are the things that affect it:
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- The number and length of the joints
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- A few photos by email, if you can
- Whether it has been sealed before
- What’s wrong with the joints now
- Whether it’s a home or a business
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
What happens on the day
When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work begins. Most jobs take a few hours, depending on how many layers have to come out. In a London area like Barnes, 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.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
How to prepare
- On commercial sites, let us know about site rules
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

What else we do in Barnes
Different surfaces, different methods
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
