Renlon came to damp proof our living room as we are under going a refurb. We used Renlon as our neighbours had work done over 19 years ago by them and haven't had a problem since. There was a survey fee however we felt the cost was reasonable considering the detail and expertise of the report and drawings compared to a free one we had carried out by another company. Pricing was fair and the works was completed within the estimated time frame. Survey fee was taken off final bill. Happy customer.
