Remedial sealant for homes and businesses in Tewin
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. If you have products that weren’t meant for the joint and repeat leaks from the same joint, we can help, whatever the surface.
For a small place like Tewin, remedial sealant is planned like any other job: the journey and access are simply agreed in advance. In the bathroom or kitchen, the work is the same as in any town.
Each job carries a 12-month guarantee, whatever its size.

Tewin: your questions answered
Do you cover smaller places like Tewin?
Yes, Tewin is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Welwyn North station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator.
Someone sealed over the old bead. Can you fix it?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
How long does the work take?
The number of joints and layers decides it. We’ll tell you before work begins.
Will you leave a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we are using.
Can you match the sealant colour?
We help you choose a colour that suits. The product needed can limit the range.
What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. It normally takes a few hours, depending on how many layers have to come out. Somewhere like Tewin needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
Before we arrive
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

Tewin homes and their sealant
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
For an older house near a landmark such as Church of St Peter, walls and floors in older homes can move, and sealant and grout show it first. Rented homes near Welwyn North station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants. Managing a site like Ridgeway Academy? Then 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.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Deal with small splits early
- Keep movement joints clear of mortar and paint
- Keep bleach and abrasives off the bead
- Report a tray that rocks or a worktop that lifts
Where we have pointed out another fault, have it put right, or the new joint may fail again.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants keeps a property looking cared for.
How the job changes by surface
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Mouldy bath & shower sealant
Mould often spreads under the bead as well as through it. We treat the exposed joint once the bead is out so the new sealant starts clean.
