Remedial sealant in Heathfield, done properly
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. We work on leaking tray & enclosure joints, botched or over-sealed joints and expansion joints, and the jobs we see most are caulk or the wrong sealant used in a wet area and gaps opening along the back of the worktop.
In a smaller place like Heathfield, homes are mostly houses and bungalows rather than flats, some older and some much newer. Bathrooms and kitchens here get the same daily wear as anywhere, and the sealant and grout show it first.
All our work comes with a 12-month guarantee.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
What we do, step by step
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours, depending on how many layers have to come out in most cases. A visit to Heathfield is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions
- Keep pets and children clear of the area while we work

When it isn’t the sealant
We won’t take on work that won’t last, so here’s what sealant cannot put right:
- A tray or bath that’s cracked
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A leaking trap, valve or supply pipe
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.

Do you need remedial sealant in Heathfield?
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. Each fails in its own way.
If you can see any of these, it’s time to have the joints looked at:
- Products that weren’t meant for the joint
- A second bead peeling off the first
- Torn expansion joints
- Wide, uneven beads that look worse than the old ones
Managing a site like Parkside Community Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
What to look for in a quote
- How hidden problems are handled
- Is the old sealant removed completely?

Why it’s worth doing now in Heathfield
Stripping out botched sealant adds time to a 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 Heathfield, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Old sealant always removed completely
- Every job guaranteed for a year
- Over 20 years’ experience
- You choose the colour before work begins

How the job changes by surface
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. We strip it, degrease the joint and reseal.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Heathfield questions
Will you come out to Heathfield?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Heathfield for remedial sealant?
Yes. We work across London and the South East, and Heathfield is part of that. Just phone 0345 464 0079 or email us with a few details of the job.
Do you have insurance?
Yes. Mr Mastic is fully insured.
What if the leak is not the sealant?
Then we explain what we’ve found. You may need a plumber or bathroom fitter before any new sealant goes on.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, so we find that first.
Bathrooms and kitchens in Heathfield
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 St Richards Church, older homes can move a little, which is hard on rigid grout and tired sealant.
