Remedial sealant in King's Walden
Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. New sealant only bonds to a clean, dry joint. If you are dealing with thick, messy sealant smeared over tiles and sealant applied over old sealant that has lifted, we can put it right.
For a small place like King's Walden, remedial sealant is planned like any other job: it just means planning the journey and access beforehand. Once we are there, the bathroom or kitchen gets the same care as anywhere else.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Signs you need remedial sealant in King's Walden
Products get mixed up: 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.
Any of these means the joints need attention:
- Caulk or the wrong sealant used in a wet area
- Gaps opening along the back of the worktop
- A second bead peeling off the first
- A shower that leaks however often it’s resealed
For landlords with property near Luton Airport Parkway station, a joint that keeps failing is best fixed properly while the property is empty.
Before booking anyone
- How the joint is cleaned and prepared
- Is VAT in the price?
- Whether they’re fully insured
- Who turns up on the day
Bathrooms and kitchens in King's Walden
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.
If you look after a building such as Breachwood Green Junior Mixed and Infant School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. Homes close to Church of St Mary include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Landlords, agents and businesses in King's Walden
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Surface by surface
Mouldy bath & shower sealant
Mould that has grown into silicone doesn’t clean out for good. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.
When something else is needed
Sealant isn’t the answer to every problem, and we will tell you before any work starts. It will not solve:
- Movement from fittings that aren’t supported
- A tray or bath that’s cracked
- Leaks from a shower valve, waste or pipework (a plumber’s job)
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before booking.
Surfaces we seal
- Failed movement joints
- Shrunken worktop sealant
- Mouldy bath & shower sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a typical bath or shower, longer where several layers have been applied in most cases. In a small place like King's Walden, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
Before we arrive
- Let us know about stairs, lifts or work at height
- Tell us about any water getting in
- Clear the area around the work
