When it isn’t the sealant

Some problems need a builder, plumber or other trade rather than us:

  • A shower tray, bath or basin that’s cracked or broken
  • Certifying fire stopping or building compliance
  • Leaking pipework, valves or wastes (a plumber’s job)

If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think before you book.

Surfaces we seal

  • Office washrooms & kitchens
  • Hotel bathrooms
  • Welfare facilities

  • Retail & leisure sites

How it works

All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of rooms. A visit to Blacklands 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. We start by looking at the rooms and agreeing what’s needed.
  2. We agree when we will work, with early or out-of-hours slots where they can be arranged.
  3. Areas are protected and the failed sealant removed.
  4. Joints are dried, then resealed and tooled neatly.
  5. Housekeeping or site staff are told when each area can be used.

How to prepare

  • Clear items away from the joints we’re working on
  • Mention any tricky access
  • Plan for the work area to be out of bounds to pets and children

Why it’s worth doing now in Blacklands

A leaking shower in a hotel room or flat above can damage the ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. Around Blacklands, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.

The cost reflects the work involved, not guesswork. That’s why we ask about the job first.

Why Blacklands clients choose us

  • White, clear, grey or coloured to suit, where the product allows
  • Arbo and Everbuild products
  • ARBOMaster approved applicator
  • Neat joints and a tidy finish

Take a look at our cost guide and what customers say.

Looking after it afterwards

So the new joints stay in good condition:

  • Keep strong chemicals and scourers off the joints
  • Pass on the cure time to whoever cleans the rooms
  • Put a squeegee in each shower
  • Log resealing so you know what’s due

Keep the extraction running and maintained. In internal bathrooms, a weak or broken fan lets moisture linger, and that’s what keeps mould away.

Black sealant in a staff washroom or guest bathroom draws complaints. Left long enough, it spreads through the bead, so the fix is replacement.

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.

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.

For landlords and businesses

For anyone letting property in or around Blacklands, several properties can be quoted together. Just tell us the addresses and what each one needs.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

How the job changes by surface

Office washrooms & kitchens

Office washrooms and tea points are used all day, so the work can be arranged for quieter times. Basins, urinals, worktops and sinks are all resealed.

Student & care accommodation

Empty rooms between terms or tenancies are easy to reseal, though occupied rooms can be done too.

Workplaces and buildings in Blacklands

For seaside hotels, guest houses and holiday lets around Blacklands, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. 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 church, hall or community building such as Christ Church, its kitchen and washroom sealant needs looking after like anywhere else. For landlords with property near Ore station, we can quote for one property or a whole portfolio of rentals. Managing a site like Ark Blacklands Primary Academy? Then busy washrooms and kitchens can be resealed in phases so they stay open.
