How we handle commercial sealant in Cold Ash

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, chosen to suit each joint.

Do you need commercial sealant in Cold Ash?

Staff kitchens and food areas see constant splashing and wiping, so sealant there wears and stains. Worktop and sink joints are often the first to go.

People generally contact us when they notice something like this:

  • Washroom sealant that looks dirty however often it’s cleaned
  • Washrooms that need sorting before an inspection
  • Sealant failing again soon after quick repairs
  • Leaks from showers into rooms or ceilings below

If you look after a church, hall or community building such as St. Mark's Church, its kitchen and washroom sealant needs looking after like anywhere else.

Before you book anyone

  • Which sealant they’ll use, and why
  • When the joint can take water or movement
  • What happens if the job turns out different
  • Whether all the old sealant comes out first

What happens on the day

Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take a morning for a small washroom, and a planned programme for bigger sites. Somewhere like Cold Ash needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. Tell us the rooms, hours and site rules, and we’ll plan the programme.
  2. We go through your site’s paperwork needs, such as RAMS, before work begins.
  3. In each room, the old bead comes out and the joint is cleaned and treated.
  4. Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
  5. Each finished area is checked with you and given a cure time.

How to prepare

  • Mention any parking rules near the property
  • Move anything stored near the joints
  • Let us know about stairs, lifts or work at height

Aftercare tips

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

  • Schedule work around occupancy
  • Don’t leave a failed joint until the next refurbishment
  • Pass on the cure time to whoever cleans the rooms
  • Encourage users to squeegee shower walls

Strong chemicals and scourers wear silicone out faster. Ask cleaners to use mild products and soft cloths on the sealant.

Watch for the warning signs: mould, splits, peeling corners or water marks downstairs. Any of these means the joints need attention.

No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

Yes. All of the old material is cut out and the joint cleaned.
