Remedial sealant in Great Gaddesden, done properly
Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. If you have products that weren’t meant for the joint and movement joints that have split or pulled away, we can put it right, whatever the surface.
For a small place like Great Gaddesden, 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Great Gaddesden homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
In the older streets around Church of St John the Baptist, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Berkhamsted station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. For site and facilities teams at buildings such as Great Gaddesden Church of England Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How the visit works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before any work starts. The work generally takes a few hours for most joints, depending on how much old sealant has to come out. Somewhere like Great Gaddesden 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.
- We protect the surfaces around the joint.
- The botched or failed sealant is cut away completely.
- 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.
Getting ready for the visit
- Let us know about parking restrictions
- Where the joints are inside, avoid wetting them before we arrive

Should I try it myself first?
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.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.

Keeping the joints in good condition
Looking after new joints is easy:
- Don’t point over movement joints
- Clean sealant with mild products only
- Have loose fittings fixed before resealing
- Air the bathroom so the sealant can dry
Keep an eye on the joint at first, especially if movement was the problem. Should anything change, ring 0345 464 0079 or send us an email.
If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.
Why deal with it now?
Ripping out a bathroom is not generally needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we will tell you. Around Great Gaddesden, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.
