Commercial sealant around Cotman's Ash

Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.

For site and facilities teams at buildings such as Kemsing Primary School, washroom and kitchen sealant can be programmed around term times or opening hours. Community buildings like Church of Saint Mary the Virgin are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.

Landlords, agents and businesses in Cotman's Ash

Housing providers, facilities teams and property managers book us too in Cotman's Ash and across Kent. We can quote a run of properties together.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Check the joints during routine room inspections
  • Don’t leave a failed joint until the next refurbishment
  • Book larger programmes for quieter times of year
  • Ask cleaners to go gently on the silicone

Extract fans need to work. Where a room has no window, the fan is what dries it out, and that is what keeps mould away.

Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. When you see them, it’s time to plan a reseal.

Common problems we fix in Cotman's Ash

Quick fixes come back quickly. Sealing over old silicone, sealing wet joints or using the wrong product all lead to the same thing: another reseal before long.

People usually contact us when they notice something like this:

  • Mouldy washroom sealant that staff and guests notice
  • Tired sealant in let properties
  • Washrooms that need sorting before an inspection
  • Worktop sealant that has shrunk and stained

For landlords with property near Kemsing station, sealant work can be quoted for a single flat or a whole portfolio.

What to look for in a quote

  • How much experience the applicator has
  • Whether the sealant suits the joint
  • Whether they’re fully insured
  • How long to leave it before use

Choosing a sealant specialist

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.

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.

Honest limits

In fairness, there are a few things sealant won’t fix:

  • Assessing what fire stopping a building needs
  • A shower tray, bath or basin that is cracked or broken
  • Water damage behind the tiles that needs a tiler or builder

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Surfaces we seal

  • Hotel bathrooms
  • Retail & leisure sites
  • Student & care accommodation
  • Welfare facilities
  • Rental portfolios
  • Office washrooms & kitchens

Quotes for commercial sealant in Cotman's Ash

Jobs vary more than people expect. The main factors:

  • Working hours on commercial sites

  • The number of rooms or windows

Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

  • The type of property
  • What’s wrong with the joints now
  • Photos by email, if that is easy
  • Any previous sealing or DIY work

Asking for a quote is easy: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.

What happens on the day

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. Somewhere like Cotman's Ash needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. Tell us the rooms, hours and site rules, and we will plan the programme.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. Old sealant is cut out room by room and joints cleaned and treated.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Rooms are handed back in order, each with its cure time.

Before we arrive

  • For business premises, tell us about site rules or sign-in
  • Keep pets and children clear of the area while we work
  • Clear items away from the joints we are working on
