About our remedial sealant in Hartlip
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you call 0345 464 0079 or send us an email, and say how long ago it was last done. We work on mouldy bath & shower sealant, leaking tray & enclosure joints and failed movement joints, and common reasons people get in touch are leaks that keep coming back after resealing and sealant peeling off a dusty or damp surface.
In a village or hamlet like Hartlip, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
All our work comes with a one-year guarantee.

What affects the cost of remedial sealant
We do not publish a price list. What we look at:
- The size of the job
- Which sealant suits the joint
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What we need to know
When you call or email, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- A few pictures by email, if you can
- How many joints, rooms or windows are involved
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
What else we do in Hartlip
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Keep bleach and abrasives off the bead
- Look for stains below bathrooms now and then
- Never fill a movement joint with mortar or grout
- Don’t wait for a small gap to become a leak
Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just phone 0345 464 0079 or drop us an email.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
Common questions in Hartlip
Is Hartlip within the area you cover?
Yes, Hartlip is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Newington station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
What if resealing won’t fix my leak?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
When is the sealant fully cured?
It depends on the product. Before we leave, we will tell you the cure time.
Is remedial work guaranteed?
Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.
Can you reseal a split movement joint?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
How long does the work take?
Allow a few hours for a typical bath or shower, longer where several layers have been applied. You will know the timing when we quote.
Are you insured?
Yes. Mr Mastic is fully insured.
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 call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Why act early in Hartlip
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, leaving the leak in place and one more layer to cut out later. Where a wall is exposed, as many are in small places like Hartlip, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first.

Surface by surface
Mouldy bath & shower sealant
Where mould keeps coming back, ventilation is generally part of the cause. Along with resealing, we will mention if the room needs better ventilation.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
What we do, step by step
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on how many layers have to come out. Somewhere like Hartlip needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- Finally we finish the joint and talk you through what we found.
Preparing for the visit
- Clear items away from the joints we are working on
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or email us.
Related advice
When something else is needed
New sealant cannot fix everything, and we’ll tell you before we start. Sealant won’t put right:
- A tray or bath that’s cracked
- A bath, tray or worktop that moves until it’s properly fixed
- Older mastics that may need an asbestos check before removal
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.

Remedial sealant around Hartlip
Hartlip is within about 3 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you live in an older home near Church of St Michael, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For site and facilities teams at buildings such as Hartlip Endowed Church of England 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. Rented homes near Newington station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
