Remedial sealant in Sonning Common

How we handle remedial sealant in Sonning Common

Remedial jobs in Sonning Common usually fall into a few patterns: sealant over sealant, mould under the bead, leaks that come back and movement joints that have split. Each is stripped back and done again properly. We work on failed movement joints, shrunken worktop sealant and leaking tray & enclosure joints, and people most often call us about beads that never stuck properly and gaps opening along the back of the worktop.

Even in a smaller place like Sonning Common, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: all the old material out, the joint cleaned and dried, then new sealant or grout.

We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Different surfaces, different methods

Worktops & kitchens

Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed.

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 it works

We keep the work tidy and contained to the joints we are treating, 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. A visit to Sonning Common is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.

  1. Surrounding tiles, trays and frames are protected first.
  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.

Why deal with it now?

Leaks that are left keep doing damage out of sight: soaked floorboards, ceiling stains below and blown plaster. By comparison, sorting the joint is quick. Homes in smaller places like Sonning Common can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

How we quote for remedial sealant

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

  • The type of sealant required
  • How many rooms, windows or areas are involved
  • Whether old sealant or filler has to be cut out
  • Whether the work is at height

What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

Asking for a quote

There’s no need for technical detail. It helps if you can tell us:

  • If someone has resealed it before
  • Any access issues, like height or stairs
  • The type of property
  • How many joints, rooms or windows are involved

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. Whenever you’re ready, ring 0345 464 0079 or email us.

What remedial sealant looks like in Sonning Common

Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

If you look after a building such as Sonning Common Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes. If you live in an older home near The Church of Christ the King, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Honest limits

We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:

  • Plumbing leaks behind walls or under trays
  • A tray or bath that’s cracked
  • A tray or worktop that needs refixing first

Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly before booking.

What we seal

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

Keeping the joints in good condition

No joint lasts for ever, but care makes a real difference. A few tips:

  • Keep bleach and abrasives off the bead
  • Check trays and worktops do not move
  • Check ceilings under showers for marks
  • Run the fan after every shower

Keep an eye on the joint at first, particularly where the original failure was caused by movement. If anything changes, just ring 0345 464 0079 or drop us an email.

A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. Resealing while the edges are sound is simpler.

Do you need remedial sealant in Sonning Common?

Silicone only bonds to surfaces that are clean and dry. Residue, moisture or dust left in the joint weaken the bond, so it starts lifting sooner than it should.

It’s worth asking for a quote if you see:

  • Repeat leaks from the same joint
  • Smears and lumps from a botched reseal
  • Torn expansion joints
  • Worktop sealant that has shrunk and split

If you let a flat or house near Henley-On-Thames station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

Before booking anyone

  • What guarantee comes with the work
  • Whether you can choose the colour
  • What happens if they find a problem under the old sealant
  • How much experience the applicator has

Questions from Sonning Common

Do you cover Sonning Common for remedial sealant?

Yes. Our work covers London and the South East, and Sonning Common is part of that. Just phone 0345 464 0079 or email us with a few details of the job.

Can you help a landlord with a rental near Henley-On-Thames station?

Yes, we work for landlords and agents. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.

What if the leak is not the sealant?

We check for that before we reseal. If the fault is elsewhere, you will know before any work is done.

Do you have insurance?

Yes. Mr Mastic is fully insured.

Do you fix expansion and movement joints?

Yes. The depth is set with backing so the sealant only bonds to the two sides, which lets it stretch.

Do the sealants smell?

That depends on the sealant. Some products have a noticeable smell, others very little.

How do I get a quote for remedial sealant in Sonning Common?

We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.

How long will it take to strip and reseal the joint?

Longer than a simple reseal, because every layer has to come out. Most jobs take a few hours.
