Remedial sealant for homes and businesses in Merton Abbey

If a joint has been resealed and is leaking again, it’s worth a proper look. It helps to have pictures when you ring 0345 464 0079 or email us, along with when it was last resealed. We work on mouldy bath & shower sealant, failed movement joints and expansion joints, and common reasons people get in touch are a shower that leaks however often it’s resealed and sealant applied over old sealant that has lifted.

In much of London, period terraces have been converted into flats over the years, and bathrooms were often squeezed into small rooms. A compact bathroom that steams up every day is hard on silicone and grout.

All of our work is guaranteed for twelve months.

How the visit works

You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes a few hours for most joints, depending on how much old sealant has to come out in most cases. In Merton Abbey, 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. We protect the surfaces around the joint.
  2. The botched or failed sealant is cut away completely.
  3. The joint is degreased and checked for movement and leaks.
  4. Once dry, a suitable sealant is applied and tooled.
  5. We give you the cure time and explain what caused the failure.

Getting ready for the visit

  • Let us know about earlier repairs to the joints
  • Plan for the work area to be out of bounds to pets and children
  • Tell us about any water getting in

Aftercare tips

Good habits help new joints last longer. Our tips:

  • Keep movement joints clear of mortar and paint
  • Find out why the sealant failed first
  • Report a tray that rocks or a worktop that lifts
  • Look for stains below bathrooms now and then

If we’ve found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant can’t hold back a problem underneath.

Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.

How we quote for remedial sealant

Some jobs are bigger than they look, and some smaller. The main factors:

  • Working hours on commercial sites
  • Access and height
  • How many rooms, windows or areas are involved
  • The amount of work

Combining jobs into one visit is usually more efficient than separate visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.

What we need to know

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • The rough size of the job
  • Where the job is, and your postcode
  • Photos by email, if that is easy
  • What the problem is, such as mould, gaps, leaks or cracking

Getting a quote is simple: tell us what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we will take it from there.

Work for landlords, hotels and businesses

We also work for property managers and facilities teams. We can quote a run of properties together.

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

What remedial sealant looks like in Merton Abbey

In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early. London has hard water, which leaves limescale on sealant, grout and taps.

As a London address, Merton Abbey can be tricky for parking: let us know about parking bays, permits or a driveway. Letting a property close to Haydons Road station? Then botched sealant from a previous quick fix is easier to strip out between tenants. Schools such as Haslemere Primary School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

FAQs for Merton Abbey

Is parking a problem for a job in Merton Abbey?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

Could a tired shower seal in my Merton Abbey flat affect the neighbours below?

Yes, and the first sign is often a stain on the ceiling below. Cutting out the old sealant and laying a new bead early stops it getting that far.

Will there be a smell?

Possibly a little. Any smell clears as the sealant cures.

Are you an approved applicator?

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

What do you put in the joint?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Do I have to be there?

That depends on where the joints are. For work indoors, someone needs to let us in.

Can I add another job to the visit?

Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Do you have insurance?

Yes, we’re fully insured for every job we do.

Honest limits

Before booking, it’s worth knowing the limits too:

  • A tray or worktop that needs refixing first
  • Cracks in the fitting rather than the joint
  • Tiles that have come away from the wall

Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

What we seal

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

Why it’s worth doing now in Merton Abbey

Spraying mould remover on a sealed-over joint does not reach what’s underneath. The layers have to come out, so the joint can be treated and resealed. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Merton Abbey.

Surface by surface

Windows & doors

Frames resealed over the top end up with hard, layered mastic. All of it is cut out and the frame and wall cleaned before backing and resealing.

Leaking trays & enclosures

Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before we reseal.
