Remedial sealant in Upper Farringdon

Landlords, agents and businesses in Upper Farringdon

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Remedial sealant for homes and businesses in Upper Farringdon

Water on the floor does not always mean failed silicone. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we will tell you rather than reseal something that won’t fix it. We work on expansion joints, botched or over-sealed joints and leaking tray & enclosure joints, and people most often call us about floor or wall movement joints that have failed and leaks that keep coming back after resealing.

Homes around Upper Farringdon are mostly 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.

We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Have loose fittings fixed before resealing
  • Get the cause of a repeat leak found before resealing
  • Look for stains below bathrooms now and then
  • Air the bathroom so the sealant can dry

Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.

If a joint has failed more than once, stop resealing it. Have someone find out why, otherwise the next attempt will fail too.

What we cannot put right

New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Failed tanking or loose tiles behind the sealant
  • A tray or bath that is cracked
  • Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed

If in doubt, ring 0345 464 0079 or email us and we will say what we think.

What we seal

  • Leaking tray & enclosure joints
  • Shrunken worktop sealant
  • Mouldy bath & shower sealant
  • Expansion joints
  • Failed movement joints
  • Botched or over-sealed joints

DIY versus a professional finish

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

What we’re called out for in Upper Farringdon

Joint depth matters. A bead bonded on three sides, or laid too thick, cannot flex, so it tears when the joint moves. Backing sets the depth and stops that.

Keep an eye out for these signs:

  • Decorators’ caulk around a bath or shower
  • Leaks that keep coming back after resealing
  • Floor or wall movement joints that have failed
  • Black mould underneath the bead

For landlords with property near Alton station, a joint that keeps failing is best fixed properly while the property is empty.

What your quote should include

  • Whether they seal over old material or remove it
  • Which sealant they’ll use, and why
  • Who does the work, and how experienced they are
  • How long the guarantee is

How to choose a mastic man

Different surfaces, different methods

Over-sealed & botched joints

A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.

Mouldy bath & shower sealant

Mould can sit behind the silicone, not just in it. Once it’s all removed, the joint is treated.

What happens on the day

Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. In a small place like Upper Farringdon, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First we work out whether the problem is the sealant, movement or a leak.
  2. Old beads and residue are removed down to clean surfaces.
  3. We treat any mould and dry the joint thoroughly.
  4. The right product goes in, with backing where the joint moves.
  5. We finish neatly and point out anything that needs another trade.

Preparing for the visit

  • Tell us if parking is tricky
  • Tell us about any previous sealing or DIY attempts
  • On commercial sites, let us know about site rules

Do you cover smaller places like Upper Farringdon?

Yes, Upper Farringdon is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Someone resealed my shower and it’s leaking again. Can you help?

Yes, normally. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.

Is there any odour?

Sometimes, a little. Any smell clears as the sealant cures.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

What should I tell you?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply call 0345 464 0079 or send us an email.

When is the sealant fully cured?

Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.

Can old silicone be taken off without scratching the tiles?

Yes, with care. The old bead is cut and lifted with tools that suit the surface, then clean off the residue. Any existing damage is pointed out before any work starts.
