Why it’s worth doing now in Southcourt
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours, depending on how many layers have to come out. It’s far less disruption than resealing the same joint again and again. Homes in smaller places like Southcourt can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
Why us?
- Old sealant always removed completely
- Fully insured
- Trusted Arbo and Everbuild sealants
- Sealant colour chosen to suit

Remedial sealant in Southcourt, done properly
Water on the floor doesn’t always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that’s what we find, we’ll tell you rather than reseal something that will not fix it. Typical jobs include beads that never stuck properly and dark patches showing through the sealant, across shrunken worktop sealant, mouldy bath & shower sealant and expansion joints.
Smaller places like Southcourt still have plenty of bathrooms that work hard every day. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: all the old material out, the joint cleaned and dried, then new sealant or grout.
Your job is guaranteed for a year, as with all our work.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, 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.
The process
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on how many layers have to come out in most cases. A visit to Southcourt is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
How to prepare
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Bathrooms and kitchens in Southcourt
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. Southcourt has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
For an older house near a landmark such as Church of the Good Shepherd, older homes can move a little, which is hard on rigid grout and tired sealant. Rented homes near Aylesbury station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. If you look after a building such as Ashmead Combined School, we reseal washrooms and kitchens in schools and businesses as well as homes.

Surface by surface
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, matched to the frame colour.
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.
What sealant work cannot fix
Some problems need a builder, plumber or other trade rather than us:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Cracks in the fitting rather than the joint
- A tray or worktop that needs refixing first
Not sure which it is? You can ring 0345 464 0079 or drop us an email and we will tell you honestly before you book.
Surfaces we seal
- Expansion joints
- Shrunken worktop sealant
- Leaking tray & enclosure joints

Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Someone sealed over the old bead. Can you fix it?
Yes. We cut out all the layers and clean off the film, before resealing with a single bead.
What if the leak is not the sealant?
We’ll tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing won’t fix it, and we won’t reseal for the sake of it.
Do you guarantee remedial jobs?
Yes, for 12 months. If we have pointed out another problem, getting it fixed helps the new joint last.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all.
Can you fix a reseal that hasn’t worked?
Yes, generally. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Keep the room well ventilated
- Find out why the sealant failed first
- Don’t wait for a small gap to become a leak
- Always have old sealant cut out, not covered
Keep the room ventilated: run the fan during and after showers, or open a window.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
