Remedial sealant & repairs in Dedham, Essex
Problem with your failed sealant joints in Dedham? We remove the old material, prepare the joints and seal them properly.
- Black mould underneath the bead
- Sealant that came away because the surface wasn’t prepared
- Smears and lumps from a botched reseal
Signs you need remedial sealant in Dedham
How a joint is built matters as much as the product. A bead bonded on three sides, or laid too thick, cannot flex, and tears at the first real movement. Backing sets the depth and stops that.
Any of these means the joints need attention:
- A second bead peeling off the first
- Thick, messy sealant smeared over tiles
- Sealant that came away because the surface wasn’t prepared
- Decorators’ caulk around a bath or shower
Managing a site like Dedham Church of England Voluntary Controlled Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

Remedial sealant in Dedham
Getting old sealant out properly is slow, careful work. We cut out every layer, clear the residue and degrease the surfaces, without scratching tiles, trays or frames. Only then can new sealant bond. We are often asked to deal with sealant applied over old sealant that has lifted and decorators’ caulk around a bath or shower, on failed movement joints, expansion joints and mouldy bath & shower sealant.
Homes around Dedham are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
There’s a 12-month guarantee on every job, whatever its size.

FAQs for Dedham
Can you do remedial sealant in Dedham?
Yes. We work across London and the South East, and Dedham is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing.
Can you help a landlord with a rental near Manningtree station?

When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint before we leave.
Where are you based?
Mr Mastic is based in Crawley. We cover Dedham and the rest of Essex.
Someone resealed my shower and it’s leaking again. Can you help?
Yes. There’s usually a reason: sealant over sealant, movement or another leak, so we find that first.
How much does remedial sealant cost in Dedham?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Are you fully insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Should I try it myself first?
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 fails, we can still redo it.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

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 Dedham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in

What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and the residue left behind stops the next bead bonding. Careful removal is most of a remedial job. Where a wall is exposed, as many are in small places like Dedham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit usually makes better use of the time than several visits. You’ll get one clear quote for the whole job.
Why us?
- We leave the area clean and tidy
- A 12-month guarantee on all work
- Approved under the ARBOMaster scheme
- Arbo and Everbuild products

What the job involves on each surface
Movement & expansion joints
A sealant stuck to the back of the joint can’t stretch. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, and we will tell you if we find it.
What sealant work can’t fix
It helps to know what we cannot do too:
- A tray or bath that’s cracked
- Sealant in an older building that needs testing for asbestos first
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.
What we seal
- Shrunken worktop sealant
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Failed movement joints
- Mouldy bath & shower sealant
- Expansion joints
Bathrooms and kitchens in Dedham
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For landlords with property near Manningtree station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For an older house near a landmark such as Parish Church of St Mary, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
