Remedial sealant in Kingston upon Thames

Remedial sealant in Kingston upon Thames

The wrong product in the wrong joint won’t last, however tidy it looks. Out it comes, and in goes a sealant suited to the job. We work on failed movement joints, shrunken worktop sealant and expansion joints, and the jobs we see most are a second bead peeling off the first and thick, messy sealant smeared over tiles.

Hard London water leaves limescale on sealant, grout and taps alike. In Kingston upon Thames, remedial sealant is as much about a room looking cared for as about keeping water out.

Each job carries a 12-month guarantee, large or small.

How we quote for remedial sealant

We do not publish a price list. What we look at:

  • The number and length of the joints
  • Any mould that needs treating
  • How easy the joints are to reach
  • Working hours on commercial sites

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. The price is agreed before we begin.

What to tell us for a quote

A few details help us give you an accurate quote. When you ask for a quote, tell us:

  • Where the job is, and your postcode
  • Roughly how big the job is
  • Whether it has been sealed before
  • If it’s domestic, commercial or a hotel

For a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. You will have a clear quote before work begins.

Do you need remedial sealant in Kingston upon Thames?

One of the commonest remedial jobs is sealant on top of sealant. Silicone does not bond to silicone, so the new layer peels, and damp and mould settle between them.

The problems people generally mention when they call include:

  • Repeat leaks from the same joint
  • Movement joints that have split or pulled away
  • Sealant applied over old sealant that has lifted
  • Gaps opening along the back of the worktop

Kingston upon Thames is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What your quote should include

  • How the surfaces are prepared before sealing
  • Is the old sealant removed completely?
  • How long to leave it before use
  • What product goes in the joint

FAQs for Kingston upon Thames

Is parking an issue for remedial sealant in Kingston upon Thames?

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.

I live in a flat in Kingston upon Thames. Can a failed seal leak into the flat below?

Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that is down. Cutting out the old sealant and laying a new bead early stops it getting that far.

What sealant do you use?

Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.

Where is Mr Mastic based?

We work from Crawley. Our applicators cover Kingston upon Thames, along with the rest of our area.

Do the sealants smell?

There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.

What do you need from me for a quote?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or email us.

Can tenants book the work?

Of course. Check with your landlord; we can send the quote to them too.

What does remedial sealant cost?

Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.

For landlords with property near Kingston station, botched sealant from a previous quick fix is easier to strip out between tenants. If you live in an older home near Church of St Luke, older homes can move a little, which is hard on rigid grout and tired sealant.

How it works

There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for most joints, depending on how much old sealant has to come out, including the tidy-up. In Kingston upon Thames, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.

  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. New sealant goes in once the joint is dry, and is tooled smooth.
  5. You get the cure time and our view on why the joint failed.

How to prepare

  • Keep pets and children clear of the area while we work
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any water getting in

Surface by surface

Movement & expansion joints

A sealant stuck to the back of the joint can’t stretch. Backing stops that, so the sealant grips the two sides only.

Windows & doors

Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.

Landlords, agents and businesses in Kingston upon Thames

For anyone letting property in or around Kingston upon Thames, several properties can go on one quote. Just tell us the addresses and what each one needs, and photos by email help.

Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

Why deal with it now?

Spraying mould remover on a sealed-over joint does not reach what’s underneath. Removal is the only way to get at it, so the joint can be treated and resealed. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

Combining jobs into one visit usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear quote for the lot.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. We suggest:

  • Clean sealant with mild products only
  • Get the cause of a repeat leak found before resealing
  • Look for stains below bathrooms now and then
  • Have loose fittings fixed before resealing

Where we’ve pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.

A failing joint rarely gets better on its own. Each use pushes more water behind the bead, into floors, walls or ceilings. Sorting it early limits the damage.
