When required Ampteam technical department will produce a detailed customised specification for the entire installation.


Site Survey "Try" Samples


Whilst many gutters are similar in size and profile and there are many standard profiles in existence, there are very few, if any, where the roof sheet and eaves condition relationship with the gutters are the same.


We have, therefore, in the vast majority of instances, dissimilar arrangements that require an exclusive solution for the gutter liner to accommodate.


To facilitate these unique conditions Ampteam technical staff and the Approved Contractor Network, provide on site surveys to ensure a correct solution.


Detailed dimensions of gutters, eaves conditions and lengths are taken along with specific measurements of roof areas discharging to gutters with outlet positions and types of outlets being recorded.


Ampteam technical department translate this information and produce detailed drawings of the Unifold® solution together with calculations, where necessary, to prove the design.


This is normally presented, together with a supply and install quotation from an approved contractor.


The UNIFOLD® Solution


01384 252777 Phone us


In order to prove a Unifold® solution, particularly where access is deemed to be difficult, "try" samples are available to test fit the gutter. These are free of charge and are usually available within 48 hours of notification.


Cleaning and Maintenance


As with all gutters, Unifold® requires inspection and cleaning. This should be on a planned schedule, which considers the local environment and the frequency of debris build-up in the gutters. A log should be kept of all roof activity.


For detailed instructions on maintenance please refer to the Care and Maintenance guide. Through Ampteam Limited, the Approved Contractor Network is available to clean, inspect and effect necessary repairs should this service be required.


Twenty year Guarantee


The Unifold® system is backed by comprehensive 20 year guarantee. This guarantee warrants that the gutter lining is free from defects in material, manufacturing workmanship and installation.
