Remedial sealant in Southington, done properly
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we will tell you rather than reseal something that will not fix it. If you have kitchen joints letting water behind the worktop and wide, uneven beads that look worse than the old ones, we can put it right, on shrunken worktop sealant, botched or over-sealed joints and expansion joints alike.
Around Southington, it’s houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
All of our work is guaranteed for twelve months, in Southington and everywhere else we cover.

Southington 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.
For site and facilities teams at buildings such as Overton Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Letting a property close to Overton station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

What we are called out for in Southington
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
These are the problems we are asked about most:
- Repeat leaks from the same joint
- Over-sealed joints coming away
- Products that weren’t meant for the joint
- Black mould underneath the bead
Homes close to Church of St Mary include some older properties, and walls and floors in older homes can move, and sealant and grout show it first.

What we do, step by step
We keep the work tidy and contained to the area we are working on. Expect the work to take a few hours for most joints, depending on how much old sealant has to come out, and we explain the cure time before we leave. For a village or hamlet like Southington, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We look at how the sealant has failed and check for movement or a leak path.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- Moving joints get backing and a flexible sealant to suit.
- The new joint is tooled neatly and we explain anything else we found.

- Mention any sign-in or site rules at work premises

Surface by surface
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, letting the sealant flex between the two faces.
Windows & doors
Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces.
Landlord and commercial work in Southington
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
Why deal with it now?
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. It’s far less disruption than resealing the same joint again and again. Around Southington, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before work begins.

FAQs for Southington
I let a flat near Overton station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Southington?
Yes. Southington is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you remove sealant that is been put over old sealant?
Yes. Both layers come out; new silicone does not bond to old silicone, which is why over-sealing fails.
Can you remove old sealant without damaging the bath?
Yes. Residue is removed with a product suited to the surface rather than scraped hard.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
My shower still leaks after a reseal. Can you sort it?
Yes, usually. We check it’s the sealant and not the tray, valve or waste, then the joints are stripped and resealed.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.

What else we do in Southington
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Run the fan after every shower
- Get the cause of a repeat leak found before resealing
- Deal with small splits early
- Don’t point over movement joints
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
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.
DIY sealant or a professional job?
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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
