Looking after it afterwards
To keep the joints looking good and working properly:
- Report a tray that rocks or a worktop that lifts
- Use a soft cloth, not a scourer, on silicone
- Ask why a joint failed before redoing it
- Act on a lifting corner straight away
If the joint ever needs renewing, have it cut out, not sealed over. New silicone doesn’t bond to old, so the old bead should always come out first.
A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into whatever is behind or below. Sorting it early limits the damage.
Remedial sealant for homes and businesses in Green Tye
A joint that keeps failing normally has a reason. A tray that moves, a worktop that isn’t fixed, the wrong sealant or water getting in elsewhere will defeat even a perfect bead. We look for the cause before we reseal. Common call-outs are for gaps opening along the back of the worktop and a shower that leaks however often it’s resealed, on expansion joints, mouldy bath & shower sealant and failed movement joints.
Somewhere as small as Green Tye, 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.
We stand behind the work with a one-year guarantee.

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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Your questions about remedial sealant in Green Tye
Will you come out to Green Tye?
Yes, Green Tye is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Bishops Stortford station?
Yes. We work for landlords and letting agents as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Can you remove old sealant without damaging the bath?
Yes. Careful removal is most of a remedial job, especially on acrylic, enamel and uPVC.
Can you take off two layers of silicone?
Yes. We cut out all the layers and clean off the film, then the joint is resealed once.
Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
How long before the joint can be used?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
How long does the work take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours for most joints, depending on how much old sealant has to come out. Somewhere as small as Green Tye, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- We finish neatly and point out anything that needs another trade.
How to prepare
- Let us know about earlier repairs to the joints
- For indoor joints, keep the area dry beforehand if you can
- Let us know about parking restrictions

Remedial sealant in Green Tye: local notes
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
For an older house near a landmark such as Church of St Thomas, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

Common problems we fix in Green Tye
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the top layer lifts and water and mould collect between the two.
Look out for any of the following:
- Dark patches showing through the sealant
- Thick, messy sealant smeared over tiles
- Kitchen joints letting water behind the worktop
- A shower that leaks however often it’s resealed
Rented homes near Bishops Stortford station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
Before you book anyone
- How much experience the applicator has
- What guarantee comes with the work
- How the surfaces are prepared before sealing
- What the cure time is
What happens if it’s left?
Mould under a bead can’t be reached by cleaning. Removal is the only way to get at it. Where a wall is exposed, as many are in small places like Green Tye, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
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.
