About our remedial sealant in Deal
The wrong product in the wrong joint fails however neatly it’s applied. Out it comes, and in goes a sealant suited to the job. Typical jobs include kitchen joints letting water behind the worktop and wide, uneven beads that look worse than the old ones, across expansion joints, botched or over-sealed joints and shrunken worktop sealant.
Plenty of homes in a town like Deal have had new bathrooms and kitchens over the years, some more than once. Sealant run over the top of an old bead is a common cause of leaks and mould, so we take every joint back to clean before anything new goes in.
Whatever the size of the job, you get the same one-year guarantee in Deal and across Kent.

How the job changes by surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. New sealant needs a fully clean surface.
Worktops & kitchens
Kitchen joints often have grease and cleaning residue deep in them, so cleaning takes longer than in a bathroom.

Can I do it myself?
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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Use a soft cloth, not a scourer, on silicone
- Look for stains below bathrooms now and then
- Get the cause of a repeat leak found before resealing
- Have loose fittings fixed before resealing
Give the new sealant its full cure time: follow the cure time we give you.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before work begins. The work generally takes a few hours for most joints, depending on how much old sealant has to come out. In Deal, parking is rarely complicated, though it helps to know about driveways or restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- 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.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Mention if the joints have been sealed before
- Mention any tricky access
- Let us know about parking restrictions

Advice
Why it’s worth doing now in Deal
Hidden water does the most damage: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Gaps in sealant and mould in the bead never get better on their own, and in a busy household in Deal they spread with every shower and every downpour. Now is the easy time to put it right.
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.

Remedial sealant around Deal
Deal is close to the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, which wears sealant and grout out faster than in a quiet home. Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
For site and facilities teams at buildings such as Castle Community College, we reseal washrooms and kitchens in schools and businesses as well as homes. Homes close to St Saviour's include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. For landlords with property near Deal station, botched sealant from a previous quick fix is easier to strip out between tenants.
