Trusted remedial sealant in Brasted

Remedial sealant in Brasted

Not every leak is a sealant leak. 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. Common call-outs are for sealant peeling off a dusty or damp surface and products that weren’t meant for the joint, across failed movement joints, mouldy bath & shower sealant and leaking tray & enclosure joints.

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.

A 12-month guarantee comes as standard, so you are covered after we have gone.

DIY versus a professional finish

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.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

What affects the cost of remedial sealant

Your quote is based on your job. We look at:

  • The old material and how stubborn it is
  • The type of sealant required
  • The number of rooms or windows
  • How much there is to do

What it costs depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

What we need to know

When you call or email, it’s useful to know:

  • What the problem is, such as mould, gaps, leaks or cracking
  • How we’d reach the joints
  • A few photos by email, if you can
  • Where the job is, and your postcode

To get a quote, ring 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. You’ll have a clear quote before work begins.

What happens if it’s left?

Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. 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.

Doing several joints on one visit usually makes better use of the time than several visits. We’ll send you a clear quote for the lot.

What you get with us

  • Sealant colour chosen to suit
  • Full insurance on every job
  • Approved under the ARBOMaster scheme
  • Homes, businesses and hotels

Aftercare tips

After the cure time, these simple habits help:

  • Air the bathroom so the sealant can dry
  • Don’t point over movement joints
  • Check ceilings under showers for marks
  • Always have old sealant cut out, not covered

If the joint ever needs renewing, have it cut out, not sealed over. Over-sealing is how many remedial jobs start, so the old bead should always come out first.

Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.

When something else is needed

To be straight with you, there are a few things sealant will not fix:

  • Failed tanking or loose tiles behind the sealant
  • A tray or bath that’s cracked
  • A leaking trap, valve or supply pipe

If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Surfaces we seal

  • Failed movement joints
  • Shrunken worktop sealant
  • Mouldy bath & shower sealant

Remedial sealant in Brasted: local notes

London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. 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.

Homes close to Church of St Martin include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them. Managing a site like Combe Bank School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. If you let a flat or house near Dunton Green station, a joint that keeps failing is best fixed properly while the property is empty.

How the visit works

We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours, depending on how many layers have to come out, and we tell you how long to leave it before we go. In a London area like Brasted, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. We look at how the sealant has failed and check for movement or a leak path.
  2. Every layer of old sealant is cut and cleaned out.
  3. Next, any mould is treated and the joint dried.
  4. Moving joints get backing and a flexible sealant to suit.
  5. Finally we finish the joint and talk you through what we found.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Tell us if parking is tricky
  • Plan for the work area to be out of bounds to pets and children

Related advice

What the job involves on each surface

Movement & expansion joints

Bonding on three sides is a common reason movement joints tear. Backing rod or bond-breaker tape prevents it, so the sealant grips the two sides only.

Worktops & kitchens

Kitchen joints often have grease and cleaning residue deep in them, so we spend extra time cleaning.

Brasted: your questions answered

Can parking be tricky for a visit in Brasted?

In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.

I let a flat near Dunton Green station. Can you help?

Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.

Do you do commercial work?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

Can you remove sealant that’s been put over old sealant?

Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.

Does someone need to be in?

That depends on where the joints are. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

Can you match the sealant colour?

We’ll suggest a colour to suit the surroundings. The choice depends on the product the joint needs.
