How we handle remedial sealant in South Street
Remedial work is what we do when sealant has failed or been done badly. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out before the joint can be done properly. We work on mouldy bath & shower sealant, shrunken worktop sealant and expansion joints, and the jobs we see most are sealant applied over old sealant that has lifted and movement joints that have split or pulled away.
Somewhere as small as South Street, 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.
Your job is guaranteed for a year, as with all our work.

Surface by surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces.
What affects the cost of remedial sealant
There’s no set price list, because jobs vary so much. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- When we can work, for business premises
- How many rooms, windows or areas are involved
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- The rough size of the job
- The address or postcode of the job
We do not publish a price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or send us an email.
Bathrooms and kitchens in South Street
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of St Peter and St Paul, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. If you let a flat or house near Selling station, botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like Boughton-under-Blean and Dunkirk Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Check ceilings under showers for marks
- Clean sealant with mild products only
- Find out why the sealant failed first
- Do not point over movement joints
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or email us.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. A joint with sound edges is far easier to reseal.
How it works
Once we are on site, we check the joints match what you told us. 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 South 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.
- The joint is cleaned, treated for mould and left to 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.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Keep pets and children clear of the area while we work

Will it make a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
My shower still leaks after a reseal. Can you sort it?
Yes, generally. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Can you reseal a split movement joint?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, and reseal with a flexible product.
Why act early in South Street
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Where a wall is exposed, as many are in small places like South Street, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before we start.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
