- Lumpy, uneven sealant from a DIY attempt
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Bathroom resealing for homes and businesses in Kinsbourne Green
A fresh bead of silicone changes how a bathroom looks more than most people expect. Mouldy silicone makes even a new bathroom look neglected, and a neat new joint puts that right in a short visit. It also seals the gaps that let water behind the bath. We are often asked to deal with leaking joints on a shower screen and gaps between the worktop and the wall, on shower trays & enclosures, basins & vanity units and kitchen worktops & upstands.
Being in a small place like Kinsbourne Green makes no difference to the job itself: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Common questions in Kinsbourne Green
I let a flat near Harpenden station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover Kinsbourne Green for bathroom resealing?
Yes. Our work covers London and the South East, and Kinsbourne Green is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
What colours of sealant can you use?
There’s a choice: white, clear and colours to suit tiles and worktops. We can help you pick when we quote.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Kinsbourne Green.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
Surface by surface
Sinks & splashbacks
Where a splashback meets the worktop, there’s a joint that catches every splash. We renew it in clear, white or a matched colour.
Kitchen worktops & upstands
Worktop joints get wet and wiped every day. The new bead is colour-matched where it shows.
Leave it or put it right?
Leaving a split or mouldy bead only stores up trouble. Water that gets behind a bath soaks into the floor, the panel and sometimes the ceiling below, turning a small job into a building repair. In a small place like Kinsbourne Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
What you get with us
- Domestic, commercial and hotel work
- Arbo and Everbuild products
- Sanitary silicone with an anti-fungal additive in wet areas
- Colour agreed with you before any work starts
Looking after it afterwards
After the cure time, these simple habits help:
- Use gentle cleaners on the silicone
- Move toiletries away from the joint
- Wipe the sealant dry after showering
- Keep scourers and sharp tools away from the bead
Don’t stand bottles along the bead, as they hold water against it. Squeegeeing the walls and tray after use helps the joint dry.
There’s no need to wait for a full refurbishment. Like paintwork, sealant needs renewing from time to time, and renewing it as soon as it fails protects everything around it.
The process
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. Most jobs take a morning or an afternoon for most single baths and showers. Somewhere like Kinsbourne Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We look at every joint first and check for movement or leaks.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- Joints are degreased and any mould is treated.
- When the joint is dry, and a bath has been filled with water, the new silicone goes on.
- We tool the bead to a neat finish and give you the cure time, usually around 24 hours.
Before we arrive
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area

What we are called out for in Kinsbourne Green
The wrong product fails fast. Acrylic caulk and general-purpose sealants are not designed for a joint that is wet every day, so they crack, discolour or grow mould quickly. Wet areas call for a sanitary silicone with an anti-fungal additive.
Any of these means the joints need attention:
- Gaps where the bath or tray has moved
- Leaks into the floor or ceiling below
- Black spots spreading through the bead
- Sealant that has split, shrunk or peeled away
For landlords with property near Harpenden station, mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets.
What your quote should include
- How the colour is chosen
- Whether they seal over old material or remove it
- What product goes in the joint

What bathroom resealing looks like in Kinsbourne Green
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Managing a site like Wood End School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to Saint Mary the Virgin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
