Nether Street Remedial Sealant
Remedial sealant for Nether Street, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Repeat leaks from the same joint
- Mould trapped under a layer of silicone
- Worktop sealant that has shrunk and split
What happens if it’s left?
Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Where a wall is exposed, as many are in small places like Nether Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.

When it is not the sealant
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- A leaking trap, valve or supply pipe
- A tray or worktop that needs refixing first
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think.
What we seal
- Leaking tray & enclosure joints
- Botched or over-sealed joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Expansion joints
- Failed movement joints
Surface by surface
Movement & expansion joints
Joints filled with mortar, grout or rigid filler cannot move. Where it can be raked out, we replace it with flexible sealant.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning.

Nether Street homes and their sealant
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.
Rented homes near Harlow Town station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as Parish Church of St John the Baptist, older homes can move a little, which is hard on rigid grout and tired sealant.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

What else we do in Nether Street
Signs you need remedial sealant in Nether Street
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
If you can see any of these, it’s time to have the joints looked at:
- Kitchen joints letting water behind the worktop
- Dark patches showing through the sealant
- Decorators’ caulk around a bath or shower
- A shower that leaks however often it’s resealed
Managing a site like Widford School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- Who does the work, and how experienced they are
- What guarantee comes with the work
- What happens if they find a problem under the old sealant
- How the joint is cleaned and prepared
Your questions about remedial sealant in Nether Street
I let a flat near Harlow Town station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 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 do remedial sealant in Nether Street?
Yes. We work across London and the South East, and Nether Street is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can you take off two layers of silicone?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Does remedial work come with a guarantee?
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 will it take to strip and reseal the joint?
The number of joints and layers decides it. You’ll have a timescale before any work begins.
What we do, step by step
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours, depending on how many layers have to come out, and we explain the cure time before we leave. Somewhere as small as Nether Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at how the sealant has failed and check for movement or a leak path.
- All the old sealant comes out, including any layers underneath.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Getting ready for the visit
