Bathroom Resealing in Colindale
Our applicators work in Colindale on bath, shower, basin, wet room, worktop and sink resealing. Old sealant removed completely, joints prepared properly.
- A bead that has pulled away from the tiles
- A reseal done over the top of the old bead
- Lumpy, uneven sealant from a DIY attempt
What we’re called out for in Colindale
Older sealant shrinks and hardens. In kitchens it often shrinks away from the back edge, opening a hairline gap that lets water and crumbs in. Hot pans and harsh cleaners do not help.
Common reasons people contact us are:
- Black mould in the silicone that won’t clean off
- Gaps between the worktop and the wall
- Two layers of silicone, both failing
- Leaking joints on a shower screen
For an older house near a landmark such as St Matthias the Apostle church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Bathroom resealing in Colindale
We fill the bath before sealing it. A full bath sits slightly lower than an empty one, so the bead isn’t stretched the first time someone gets in. Quick jobs often leave it out, and it makes a real difference. We work on kitchen worktops & upstands, baths and sinks & splashbacks, and common reasons people get in touch are new sealant laid over old sealant that is now lifting and splits where the tray meets the wall.
In much of London, period terraces have been converted into flats over the years, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest.
You get a 12-month guarantee, the same in Colindale as everywhere else we work.

Honest limits
Sealant isn’t the answer to every problem, and we will tell you before work begins. It will not solve:
- Movement from a bath with loose feet or no proper support
- A cracked shower tray or bath (that needs repair or replacement)
- Damage behind the tiles that needs a tiler
If in doubt, call 0345 464 0079 or send us an email and we will say what we think before booking.
Joints and surfaces we work on
- Wet rooms
- Baths
- Basins & vanity units
- Sinks & splashbacks
- Kitchen worktops & upstands
- Shower trays & enclosures
Different surfaces, different methods
Sinks & splashbacks
Water getting under the rim of an inset sink can soak the worktop. We reseal the visible edge of the sink where it has failed.
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, since cooking leaves a film that stops silicone sticking. Proper degreasing is what helps the new joint last.
Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Colindale: your questions answered
Do you work for landlords with property near Hendon station?
Yes. We work for landlords and letting agents as well as homeowners. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Do you work for hotels and guest houses in Colindale?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
How long before the new sealant can get wet?
Around 24 hours is typical, and we confirm the time for the product used. Getting it wet too early can spoil the new joint.
Do you guarantee your resealing?
Yes. All our work comes with a 12-month guarantee.
Do you reseal kitchen worktops and sinks too?
Yes. Where it’s needed by the sink, we use a food-safe sealant.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
How much does bathroom resealing cost in Colindale?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before any work starts.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
Why deal with it now?
Dealing with sealant early is a short job: the work takes a couple of hours for a single bath or shower. Wait for a leak and you may be looking at panels off, drying out and redecorating too. In a flat in Colindale, 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.
Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Colindale homes and their sealant
There are hotels and other places to stay in and around Colindale. 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, which is why it’s worth fixing early.
Managing a site like Colindale Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. Colindale is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

What else we do in Colindale
What happens on the day
There is not much for you to do on the day. Show us the job and we will take it from there. The work itself takes a couple of hours for one bath or shower, or most of a day for a full bathroom and kitchen from start to finish. In Colindale, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- Joints are degreased and any mould is treated.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you are told the cure time, generally around 24 hours.
Preparing for the visit
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
