About our remedial sealant in Cox Green

Removing failed sealant is the hardest part of the job. We cut out every layer, clear the residue and degrease the surfaces, taking care not to scratch the surfaces around it. Only then can new sealant bond. Typical jobs include worktop sealant that has shrunk and split and movement joints that have split or pulled away, across failed movement joints, shrunken worktop sealant and leaking tray & enclosure joints.

Homes around Cox Green range from older cottages to more recent houses. Older homes can move a little with the seasons, which is hard on tired sealant and rigid grout.

Every job comes with a 12-month guarantee.

Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.

What affects the cost of remedial sealant

Jobs vary more than people expect. What affects the quote:

  • Mould in or behind the old joints
  • Which sealant suits the joint
  • The number and length of the joints
  • How many rooms, windows or areas are involved

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Helping us quote

To make quoting easier, let us know:

  • What’s wrong with the joints now
  • Where the property is
  • How we’d reach the joints
  • Any previous sealing or DIY work

What sealant work cannot fix

We won’t take on work that will not last, so these are the limits:

  • A tray or worktop that needs refixing first
  • Failed tanking or loose tiles behind the sealant
  • Plumbing leaks behind walls or under trays

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

What we seal

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

How the job changes by surface

Worktops & kitchens

Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed.

Windows & doors

Failed frame mastic is often hard, cracked and in several layers. We remove it all and clean back to sound surfaces before backing and resealing.

How the visit works

We keep the work tidy and contained to the joints we’re treating. The job normally takes a few hours for a typical bath or shower, longer where several layers have been applied, and we tell you how long to leave it before we go. For a job in Cox Green, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We protect the surfaces around the joint.
  2. Every layer of failed sealant is stripped out.
  3. We clean and degrease the joint and look for signs of movement or water.
  4. Once dry, a suitable sealant is applied and tooled.
  5. We give you the cure time and explain what caused the failure.

How to prepare

  • Tell us if parking is tricky
  • Mention if the joints have been sealed before
  • Where the joints are inside, avoid wetting them before we arrive

Related advice

Should I try it myself first?

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.

Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

When to call us in Cox Green

Even good sealant ages. Mould grows into the silicone, the surface hardens and the bead shrinks. At that point it has to come out.

People normally contact us when they notice one of these:

  • Gaps opening along the back of the worktop
  • Sealant peeling off a dusty or damp surface
  • Black mould underneath the bead
  • Wide, uneven beads that look worse than the old ones

Homes close to All Saints' Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Do you work for hotels and guest houses in Cox Green?

Yes. Hotel and guest-house work is part of what we do. Work can be planned room by room, and out-of-hours working can be arranged.

Can failed expansion joints be resealed?

Yes. Mr Mastic is an ARBOMaster approved applicator and we’re fully insured too.
