Remedial sealant in Butler's Cross
If a joint fails again and again, something is causing it. Movement, the wrong product or a leak from somewhere else will defeat even a perfect bead. We look for the cause before we reseal. If you’re dealing with beads that never stuck properly and caulk or the wrong sealant used in a wet area, we can put it right, whatever the surface.
Around Butler's Cross, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
You get a one-year guarantee, the same in Butler's Cross as everywhere else we work.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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.
What affects the cost of remedial sealant
Every job gets its own quote. This is what makes a difference:
- Whether there’s mould to deal with
- Whether old sealant or filler has to be cut out
- The product the joint needs
- The number of rooms or windows
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What to tell us for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- How many joints, rooms or windows are involved
- The type of property
- Photos by email, if that’s easy
- How we’d reach the joints
To get a quote, call 0345 464 0079 or send us an email with the location and a short description of the problem. You’ll have a clear quote before work begins.
How the visit works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours, depending on how many layers have to come out. In a small place like Butler's Cross, access is usually the main thing to plan. 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.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
Before we arrive
- Clear the area around the work
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
Getting a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we will take it from there.

How the job changes 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. New sealant needs a fully clean surface.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.
Leave it or put it right?
Adding more sealant is the usual quick fix, and it rarely works. It does not grip the old layer, so the leak carries on and there’s now more to remove. In a small place like Butler's Cross, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Doing several joints on one visit is generally more efficient than separate visits. We will send you a clear quote for the lot.

Bathrooms and kitchens in Butler's Cross
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.
For site and facilities teams at buildings such as John Colet School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. If you live in an older home near Church of St Peter and St Paul, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Do you do commercial work?

How long does the work take?

What we’re called out for in Butler's Cross
Even good sealant ages. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. At that point it has to come out.
Look out for any of the following:
- Smears and lumps from a botched reseal
- Repeat leaks from the same joint
- Beads that never stuck properly
- Black mould underneath the bead
Letting a property close to Little Kimble station? Then botched sealant from a previous quick fix is easier to strip out between tenants.
