Remedial sealant in Dartford, done properly
If a joint has been resealed and is leaking again, it’s worth a proper look. Send photos when you ring 0345 464 0079 or send us an email, along with when it was last resealed. If you have floor or wall movement joints that have failed and products that weren’t meant for the joint, we can put it right.
Plenty of homes in a town like Dartford have had new bathrooms and kitchens over the years, some more than once. Sealant run over the top of an old bead is a common cause of leaks and mould, so we take every joint back to clean before anything new goes in.
Your job is guaranteed for a year, as with all our work.
Common questions in Dartford
Do you work for landlords with property near Dartford station?

Is Dartford in your area for remedial sealant?

Can you strip sealant from an acrylic tray safely?

Then we explain what we’ve found. You may need a plumber or bathroom fitter.
Do you have insurance?
Yes. Mr Mastic is fully insured.
Can you match the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before work begins.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we’ll agree access with you when we book.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us.
Why act early in Dartford
Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Around Dartford, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.

What we do, step by step
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. A visit in Dartford needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Let us know about earlier repairs to the joints

Related advice
Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
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.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured for the work.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
How the job changes by surface
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
Over-sealed & botched joints
A thick bead smeared across tiles often hides mould or gaps. Taking it back shows what’s underneath, then reseal neatly.
How we quote for remedial sealant
We do not publish a price list. What we look at:
- How easy the joints are to reach
- The size of the job
- The product the joint needs
- Any mould that needs treating
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
Asking for a quote
Photos by email are helpful but not essential. Try to tell us:
- Whether it’s a home or a business
- A few pictures by email, if you can
- Where the property is
- How we’d reach the joints
We do not publish a price list. Instead, we send you a clear quote for your job. To get started, phone 0345 464 0079 or email us.

Looking after it afterwards
So the new joints stay in good condition:
- Don’t point over movement joints
- Always have old sealant cut out, not covered
- Report a tray that rocks or a worktop that lifts
- Get the cause of a repeat leak found before resealing
Do not let anyone seal over it later. New silicone does not bond to old, so the old bead should always come out first.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
