Biokil Crown Approved Contractors

Contractors, such as Bell Street Preservation, issuing the Biokil Crown 30 Year Protection Guarantee Scheme must have fulfilled the conditions and attained the standard required for acceptance as a Biokil Crown Approved Contractor. This standard is based on working to BS6576 for the diagnosis and installation of a damp-proof course and BWPDA code of practice for remedial timber infestation diagnosis and treatment.

30 Year Protection Scheme Guarantee

As a Biokil Crown Approved Contractor, Bell Street Preservation backs our confidence in our work and the materials used with a guarantee of 20 or 30 years, against a recurrence of the problem within that time. 30 years is a long time and many things can happen, including the company who issued the guarantee going into liquidation, this could render an ordinary guarantee worthless. As an Approved Biokil Crown Contractor, Bell Street Preservation is initially responsible for honouring any remedial works that may be required under the terms of the guarantee, but should we retire or cease trading the unexpired period of the guarantee will be honoured by Biokil Crown who will arrange for any necessary retreatment works to be carried out at no additional cost to the customer.  The Biokil Crown 30 Year Protection Scheme Guarantee covers materials and labour against a recurrence of Rising Damp, Woodworm, Wet Rot or Dry Rot or problems arising from John Newton dry lining in the treated area for a period of 30 years.
