About our remedial sealant in Washington

Remedial work is what we do when sealant has failed or been done badly. New sealant over old, smeared beads, unsuitable products and hidden mould all need stripping out. We work on failed movement joints, shrunken worktop sealant and leaking tray & enclosure joints, and common reasons people get in touch are smears and lumps from a botched reseal and gaps opening along the back of the worktop.

Somewhere as small as Washington, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Movement in older walls and floors tends to show first as cracked grout or split sealant.

Your job is guaranteed for a year, as with all our work.

Can I do it myself?

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

Remedial sealant in Washington: local notes

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

Managing a site like St Mary's CofE Primary School? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Homes close to The Parish Church of St Mary include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Questions from Washington

What guarantee comes with remedial sealant in Washington?

All our work, in Washington and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.

Is Washington in your area for remedial sealant?

Yes, Washington is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear price.

Are you ARBOMaster approved?

Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.

Do the sealants smell?

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

Are you fully insured?

Yes. We’re fully insured.

What should I tell you?

Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or email us.

How much does remedial sealant cost in Washington?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

Why act early in Washington

Stripping out botched sealant adds time to a reseal, but not by much: the work takes a few hours for a typical bath or shower, longer where several layers have been applied. Compared with chasing the same leak every few months, it’s time well spent. Where a wall is exposed, as many are in small places like Washington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please call 0345 464 0079 or send us an email and we’ll talk you through it.

The process

We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. Somewhere as small as Washington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We start by checking the joint for movement, leaks and the reason it failed.
  2. We strip the joint completely, removing any layers below.
  3. Next, any mould is treated and the joint dried.
  4. Where the joint moves, backing and a flexible sealant suited to the movement go in.
  5. The new joint is tooled neatly and we explain anything else we found.

Before we arrive

  • Clear items away from the joints we’re working on
  • Keep pets and children clear of the area while we work
  • Let us know about stairs, lifts or work at height

Related advice

Keeping the joints in good condition

Looking after new joints is easy:

  • Don’t add new sealant on top of old
  • Clean sealant with mild products only
  • Report a tray that rocks or a worktop that lifts
  • Deal with small splits early

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

Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Sorting it early limits the damage.

What we can’t put right

It helps to know what we cannot do too:

  • Water damage behind tiles that needs a tiler
  • Older mastics that may need an asbestos check before removal
  • Leaks from a shower valve, waste or pipework (a plumber’s job)

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