Should I try it myself first?

If you’re set on DIY, put the effort into 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.

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Run the fan after every shower
  • Deal with small splits early
  • Have loose fittings fixed before resealing
  • Never seal over old silicone

Give the new sealant its full cure time: follow the cure time we give you.

If a joint has failed more than once, stop resealing it. Get the cause found first, otherwise the next attempt will fail too.

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

Can old silicone be taken off without scratching the tiles?

Yes. Careful removal is most of a remedial job, particularly on softer surfaces like acrylic.

Common problems we fix in Potters Bar

A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.

Signs it’s time to call us include:

  • Wide, uneven beads that look worse than the old ones
  • A second bead peeling off the first
  • Black mould underneath the bead
  • Leaks that keep coming back after resealing

Schools such as Ladbrooke Junior Mixed and Infant School are buildings too, and 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.

How it works

There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours, depending on how many layers have to come out for a typical job. In Potters Bar, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.

  1. First we find out how and where the joint has failed.
  2. We strip the joint completely, removing any layers below.
  3. The joint is cleaned, treated for mould and left to dry.
  4. Moving joints get backing and a flexible sealant to suit.
  5. Finally we finish the joint and talk you through what we found.

  • Try not to wet indoor joints just before the visit
