What the job involves on each surface

Movement & expansion joints

Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.

Mouldy bath & shower sealant

Black mould inside the bead won’t scrub out. The sealant is cut out completely, the joint treated with a mould remover and dried before anti-fungal sanitary silicone goes in.

How we handle remedial sealant in Maryland

In Maryland, as anywhere, remedial jobs tend to look alike: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. We strip each one back and start from scratch. We are often asked to deal with decorators’ caulk around a bath or shower and torn expansion joints, across mouldy bath & shower sealant, failed movement joints and shrunken worktop sealant.

Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Maryland, that’s a good reason to put tired sealant and grout right early.

Every job comes with a one-year guarantee.

Your questions about remedial sealant in Maryland

I let a flat near Stratford (London) station. Can you help?

Yes. We work for letting agents and landlords as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.

Can parking be tricky for a visit in Maryland?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.

Do you guarantee remedial jobs?

Yes, for 12 months. Where we have flagged another fault, it needs fixing for the joint to last.

Do you hold any approvals?

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

What should I tell you?

Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.

Do you take out the old sealant first?

Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Can old silicone be taken off without scratching the tiles?

Yes, with care. We cut and lift the old sealant with tools suited to the surface, then clean off the residue. We point out any damage that is already there.

Can I do it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Why it’s worth doing now in Maryland

Ripping out a bathroom is not usually needed. When the fittings are sound, stripping and resealing the joints is often enough. If they’re not, we will tell you. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Maryland, the repair is bigger than a sealant job.

Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Why book with us

  • 180+ five-star Google reviews
  • A sealant colour to suit the surroundings
  • We agree the colour with you first
  • Over 20 years’ experience

Read our cost guide or what customers say.

Can I do it myself?

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.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

When something else is needed

To be straight with you, some problems need a different trade:

  • A cracked shower tray or bath (that needs repair or replacing)
  • Tiles that have come away from the wall
  • Plumbing leaks behind walls or under trays

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

What we seal

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

Maryland homes and their sealant

London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, which is why it’s worth fixing early. There are hotels and other places to stay in and around Maryland. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.

If you let a flat or house near Stratford (London) station, a joint that keeps failing is best fixed properly while the property is empty. As a London address, Maryland can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. In the older streets around Church of St John the Evangelist, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Quotes for remedial sealant in Maryland

Call for a quick quote. What matters most is:

  • The product the joint needs
  • Whether old sealant or filler has to be cut out
  • Whether the work is at height
  • Working hours on commercial sites

What it costs depends on the amount of work, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

What to tell us for a quote

When you contact us, these details help:

  • Roughly how big the job is
  • If it’s domestic, commercial or a hotel
  • Any access issues, like height or stairs
  • Where the property is

Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will take it from there.

The process

We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours, depending on how many layers have to come out. In Maryland, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  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. We reseal with a product suited to the joint, backed where needed.
  5. We finish neatly and point out anything that needs another trade.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • For indoor joints, keep the area dry beforehand if you can
  • Let us know about stairs, lifts or work at height

Getting a quote

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

How to look after the new joints

Simple care keeps the joints in good condition. We recommend:

  • Never seal over old silicone
  • Get the cause of a repeat leak found before resealing
  • Don’t wait for a small gap to become a leak
  • Never fill a movement joint with mortar or grout

Give the new sealant its full cure time: usually around 24 hours, or as long as we advise.

Don’t keep resealing the same joint. Get the cause found first, otherwise the next attempt will fail too.
