Landlords and Letting Agents

Keeping Rental Properties in Good Order

Mouldy, discoloured sealant makes a bathroom look neglected, and failed sealant can let water get behind a bath or shower and damage the walls, floor and ceiling below.

Resealing between tenancies is a simple way to freshen a property up before new tenants move in. We reseal for landlords and letting agents across Berkshire and arrange access with you, your agent or your tenant.

What we can do in a rental

  • Baths, showers, basins and kitchen worktops resealed
  • Window and door frames resealed on the inside
  • Skirting, window boards and architraves sealed ready for decorating
