Remedial sealant & repairs in Coryton, Thurrock

About our remedial sealant in Coryton
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. If you are dealing with caulk or the wrong sealant used in a wet area and repeat leaks from the same joint, we can help.
Somewhere as small as Coryton, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.
You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Landlord and commercial work in Coryton
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
What we’re called out for in Coryton
Products get mixed up: caulk where it gets wet, rigid sealant where things move, or an acetoxy silicone on a surface it can mark. None of them last.
Keep an eye out for any of the following:
- Wide, uneven beads that look worse than the old ones
- Leaks that keep coming back after resealing
- Mould trapped under a layer of silicone
- Sealant that came away because the surface wasn’t prepared
For landlords with property near Benfleet station, botched sealant from a previous quick fix is easier to strip out between tenants.

Can you strip sealant from an acrylic tray safely?

Where is Mr Mastic based?

What if resealing won’t fix my leak?
You’ll hear it from us. A cracked tray, faulty valve or leaking waste needs a different trade, so we will not pretend it will.
Do you have insurance?

Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
When something else is needed
It helps to know what we cannot do:
- A leaking trap, valve or supply pipe
- A bath, tray or worktop that moves until it’s properly fixed
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before you book.
What we seal
- Failed movement joints
- Shrunken worktop sealant

- Leaking tray & enclosure joints
- Expansion joints
Surface by surface
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.
How to look after the new joints
After the cure time, these simple habits help:
- Do not add new sealant on top of old
- Don’t wait for a small gap to become a leak
- Do not point over movement joints
- Have loose fittings fixed before resealing
Leave the new joint to cure fully before it gets wet or moves: generally around 24 hours, or as long as we advise.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied, and the area is left clean. In a small place like Coryton, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in

Advice
Bathrooms and kitchens in Coryton
Coryton is within about 1 mile of the coast. Coastal homes, holiday lets and guest houses can see heavy bathroom use in busy months, which wears sealant and grout out faster than in a quiet home. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In and around Coryton, as anywhere, good remedial sealant starts with a clean, dry, properly prepared joint.

Leave it or put it right?
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. In a small place like Coryton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
