When something else is needed

A few problems are outside what sealant work can do:

  • Damaged sanitaryware that needs replacing
  • Extraction that isn’t working, which needs an electrician or ventilation contractor
  • Fire risk assessments or certification

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

Commercial sealant in Markyate, done properly

Wet areas get anti-fungal sanitary silicone, and kitchens get a food-safe product where it’s needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. We’re often asked to deal with leaking joints in shower rooms and changing areas and leaks from showers into rooms or ceilings below, on student & care accommodation, hotel bathrooms and rental portfolios.

Commercial work around a smaller place like Markyate usually means a pub, a shop, a school or small business units rather than office blocks. Each needs the same care with its sealant as any larger building.

You get a one-year guarantee, the same in Markyate as everywhere else we work.

Should I try it myself 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.

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

What affects the cost of commercial sealant

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Mould in or behind the old joints
  • The amount of work
  • Working hours on commercial sites
  • Whether old sealant or filler has to be cut out

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

Asking for a quote

What to tell us when you ask for a quote:

  • If it’s domestic, commercial or a hotel
  • The problem you’ve noticed
  • How many joints, rooms or windows are involved
  • Where the job is, and your postcode

Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work and give you a clear price.

When to call us in Markyate

Plenty of commercial bathrooms have no window at all, and where extraction is poor, damp hangs around. That’s when black mould sets into the bead.

Most people get in touch after spotting one of these:

  • Sealant failing again soon after quick repairs
  • Worktop sealant that has shrunk and stained
  • Failed floor-level joints in accessible wet rooms
  • Tired sealant ahead of a health and safety audit

Our hiring checklist

Surface by surface

Office washrooms & kitchens

A row of basins on a vanity top has a long joint that collects water. We renew it in one tidy, continuous bead.

Welfare facilities

Welfare facilities, shower rooms and changing areas need to stay usable. We can plan the work in sections so some facilities stay open.

Will you come out to Markyate?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.

Can I choose the sealant colour?

We help you choose a colour that suits, from white and clear to greys and other shades. The product needed can limit the range.

There’s no set price, as it 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.

Workplaces and buildings in Markyate

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.

For buildings such as Markyate Methodist Church, its kitchen and washroom sealant needs looking after like anywhere else. Managing a site like Markyate Village School and Nursery? Then washroom and kitchen sealant can be programmed around term times or opening hours.

All told, the work takes anything from a few hours to several days, depending on the number of rooms.

  1. We agree a programme with you: which rooms, in what order, at what times.
  2. Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
  3. Old sealant is cut out room by room and joints cleaned and treated.
  4. We reseal with the right product for each joint.
  5. Each finished area is checked with you and given a cure time.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints
  • Where the joints are inside, avoid wetting them before we arrive
