Remedial sealant for Grays homes and businesses

What happens on the day

We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours, depending on how many layers have to come out. For a job in Grays, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.

  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.

Getting ready for the visit

Advice

Remedial sealant in Grays

Two decades of sealant work means we recognise most failures quickly. We’re ARBOMaster approved and fully insured, and remedial work carries our one-year guarantee. We work on shrunken worktop sealant, mouldy bath & shower sealant and failed movement joints, and common reasons people get in touch are torn expansion joints and smears and lumps from a botched reseal.

Grays mixes older houses with estates built more recently, and bathrooms range from decades-old suites to brand-new ones. Whatever their age, sealant and grout tend to go before anything else.

Every job is covered by our 12-month guarantee.

DIY versus a professional finish

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

Keeping the joints in good condition

How long the joints last depends on use and care. We suggest:

  • Check ceilings under showers for marks
  • Keep the room well ventilated
  • Do not point over movement joints
  • Have loose fittings fixed before resealing

Leave the new joint to cure fully before it gets wet or moves: follow the cure time we give you.

A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.

Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Is Grays in your area for remedial sealant?

Where do you work from?

Can I add another job to the visit?

Someone resealed my shower and it’s leaking again. Can you help?

Yes, usually. First we check whether the leak is the sealant at all, then the joints are stripped and resealed.

How long should I leave it?

Different products cure at different speeds, so follow the cure time we give you.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Will you leave a mess?

No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Remedial sealant around Grays

Grays is within about 3 miles of the coast. Near the coast, holiday lets and guest houses can see bathrooms used by one guest after another, and sealant and grout that work that hard wear out sooner. Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.

Managing a site like Quarry Hill Academy? Then its toilets, changing areas and kitchens need their sealant renewed like any other building’s. Rented homes near Grays station change hands often, and botched sealant from a previous quick fix is easier to strip out between tenants.

What happens if it’s left?

Leaks that are left keep doing damage out of sight: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick. Around Grays, failed sealant lets water into hidden places, such as under the floor, behind a panel or into a wall. Whatever the joint, failed sealant only gets worse.

What affects the quote in Grays

Jobs vary more than people expect. The main factors:

  • Any working-time requirements on site
  • Any mould that needs treating
  • The number and length of the joints
  • How many rooms, windows or areas are involved

What it costs depends on the amount of work, how much old material has to come out and how easy the joints are to reach. We give a clear quote before work begins.

Helping us quote

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

  • What the problem is, such as mould, gaps, leaks or cracking
  • The address or postcode of the job
  • The type of property
  • How we’d reach the joints

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved before giving you a price.

Common problems we fix in Grays

All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, especially in damp, poorly aired rooms. Then the only fix is removal and a new bead.

Any of these means the joints need attention:

  • Repeat leaks from the same joint
  • Floor or wall movement joints that have failed
  • Over-sealed joints coming away
  • Sealant peeling off a dusty or damp surface

If you live in an older home near St John the Evangelist, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Leaking trays & enclosures

Where the joints are the problem, every bead is stripped and resealed with anti-fungal sanitary silicone, including the screen profile and tray edges.

Worktops & kitchens

A loose worktop splits its sealant. It needs fixing down first, and we’ll tell you if we find it.
