Bathroom & kitchen resealing in Kingsbury, Greater London
Problem with your baths, showers and worktops in Kingsbury? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- A bead that has pulled away from the tiles
- A joint torn by a bath that flexes
- Water getting behind the bath panel
Leave it or put it right?
Most of the work in a good reseal happens before any silicone goes on: cutting out every trace of the old bead, cleaning, treating mould and letting the joint dry. Without that preparation, the new bead will not last. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Kingsbury.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or send us an email.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Open a window or run the fan so the room dries
- Use gentle cleaners on the silicone
- Look for lifting corners and small gaps now and then
- Dry the bead with a towel now and then
Keep bottles and razors off the sealant line, because they trap water against the silicone. Squeegeeing the walls and tray after use keeps water from sitting on the joint.
A failed kitchen joint is easy to miss. Water gets behind the upstand and into the edge of a laminate worktop, where it can make the board swell. Resealing before that happens protects the worktop.
How we quote for bathroom resealing
You’ll get a clear quote before work begins. It takes into account:
- Whether there’s mould to deal with
- The product the joint needs
- How much old sealant there is and how hard it is to remove
- Access and height
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
What we need to know
What to tell us when you ask for a quote:
- A few photos by email, if you can
- How we’d reach the joints
- Where the job is, and your postcode
- Any previous sealing or DIY work
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.

Kingsbury questions
Is parking an issue for bathroom resealing in Kingsbury?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Can you help a landlord with a rental near Hendon station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or email us with the details for a clear quote.
How do I get a quote for bathroom resealing in Kingsbury?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Can new silicone go straight over the old?
No, and it’s one of the main reasons reseals fail. We cut out all of the old sealant, clean the joint and start again.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How long before the new sealant can get wet?
We give you the cure time before we leave, and it’s normally around 24 hours. Using it sooner can damage the bead.
What we do, step by step
There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes around two hours for one bath or shower, longer for a whole bathroom from start to finish. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We start by protecting the area and stripping out the old bead.
- The joint is cleaned, degreased and treated for mould.
- We let it dry fully and fill the bath with water before sealing.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- We clear away and tell you when it can get wet, generally after around 24 hours.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children

What the job involves on each surface
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A sound joint along the back edge stops that.
Wet rooms
Not every wet room leak is a sealant problem. We check the joints and say so if the fault looks to be elsewhere.
